Bike conversion kit dealer to open in Hangzhou

Posted by on January 1, 2022 Comments Off on Bike conversion kit dealer to open in Hangzhou

Bike conversion kit dealer to open in Hangzhou Lin Ping 18 stores. In the past, the monthly sales volume can reach 5000 or so, one year, sales of bike conversion kit can be nearly 6 million.

“Policy were published, bike conversion kit sales plummeted, and now only sell 3,000 units a month, a decrease of 40%.” Ping Lin said, because the future direction of bike conversion kit Mo Buzhun, many customers to wait and see , and other policies intended to clear before purchase, this attitude has seriously affected sales.

In 2009, bike conversion kit also affected by the introduction of a similar standard to market, but strong opposition from the manufacturers, the standard was eventually stopped. “This last effect is not large, because this is a joint notice from the four ministries, high standard, the final implementation is more likely.” Lin Ping that, if they follow the standards, then the bike conversion kit I am afraid that no one bought.

The bike conversion kit on the market price of 1,000 yuan to 3,000 general of dollars, but the price is only a few hundred dollars a bike. “If the bike conversion kit 20 kilometers per hour speed limit, speed is not such as bicycles, who are willing to spend a thousand or even a few thousand dollars to buy electric cars?” Entry pine to ask, since the use of bike conversion kit for the majority of office workers, each day use of a dozen kilometers, this distance, cycling and not feel tired.

“40 kg weight limit is also very funny.” Lin Ping excuse, a bike conversion kit, battery weight with motor, coupled with two wheels and brakes, doing probably 38 kg or so, then only 2 kg allocated to the frame. “2 kg of the frame, how to use will be broken, so the car can be safe? How a solid frame have to 10 kg!”

Lin Ping electric cars are mainly sold to Hangzhou City and its suburbs. Urban Fortunately, after the sale will automatically get a license, so the impact of policy on the sales of fairly small; but not the same suburb, sold the car without a license, because it involves the future will be allowed on the license, the business was blow more.

“National policy is clear impact on sales.” Said Lin Ping, Zhejiang earlier provisions for bike conversion kit is the maximum speed of not more than 25 km / h, weight does not exceed 50 kg. Despite the loose 10 kg, however, to compliance is not easy, so some consumers buy the product 36 volts, 48 ​​volts than a battery electric car less, less the weight of several kilograms. However, the 36-volt electric car endurance enough to use for some time, electric cars can go more than 20 kilometers, no way, some consumers had to spend money to modify the battery, the result would be more dangerous.

Lu Vehicle Co., Ltd. Deqing Huzhou sales was mainly targeted at rural users, Lv Jianhong, chairman, said before the monthly sales of about 350, now down to 300, the policy direction for rural customers somewhat concerns. “However, customers still favor the eventual purchase of the speed of faster, more expensive electric cars.” Lv Jianhong explained that, while the fastest speed of 35 km bike conversion kit sold for $ 2500, while the speed of 25 km only sell 1,900 yuan, but the Most consumers are still willing to buy the kind of 2,500 yuan, rural road as far uphill to go downhill bad.

Luyuan Electric Vehicle Co., Ltd. Ni Jie, chairman admitted, since the four ministries to strengthen bike conversion kit release management policy, Luyuan sales significantly affected, but the past few years, the entire bike conversion kit-sector output and output value in the rapid growth. Jie Ni bike conversion kit does not agree with a huge safety risk to the statement, he retorted: “According to statistics, in 2009 the number of deaths due to electric cars more than 3600, more than 5,000 people died while cycling, there are several automobile deaths per year million, the highest was eighty-nine million, bike conversion kit deaths in these types of transport in the lowest. ”

Enterprises in the South hardest hit

Policy of a four ministries, bike conversion kit companies have expressed the hope that national authorities will seriously study the needs of consumers and industry about the actual situation, the appropriate speed limit standards and to improve vehicle quality standards.

“If we can determine the speed limit 30 km to maintain the country’s 120 million electric car how almost no modification.” Ni Jie said Zuoxiu academicians advocated domestic bike conversion kit of the speed limit be fixed at 35 km, policies and conditions in front of the speed appear to be “a little high.” In the U.S., bike conversion kit of the speed limit is 32 km, 25 km speed limit in some countries in Europe.

For a long time, bike conversion kit according to the traditional two camps are divided into north and south, the northern production bike conversion kit light, smart, and South production bike conversion kit bigger in size, speed, a style. “Southerners like to buy bigger, prettier of the electric car, do not like to pedal the bike is also equipped with electric cars.” Lv Jianhong that this relationship, and Southerners have more face-saving.

“South of the production car, a lot of weight to seventy to eighty kilograms, the north will more than fifty kilograms.” Lifan Technology Co., Ltd. is responsible for research and development of electric vehicle technology, Tan Bo introduction. The next best car industry, chairman of Tianjin car Xiaoming also believes that the speed limit so that once the strict implementation of the South against larger enterprises. He said the policy of pressure will bring two changes: one is due to reduced speed, the original by bike conversion kit to make a living will is no longer used, this will inevitably lead to market decline; another impact on the industry, the South ” luxury cars “section gradually disappear, and may even be completely gone, no longer have two camps north and south” personality “differences.

Market share will further focus

Some industry sources believe that the four ministries policies show the automotive, motorcycle industry favoritism. “Bike conversion kit motorcycle industry and competitive relationship between the industry, but the motorcycle industry a powerful force, lobbying ability, compared to just develop the bike conversion kit industry almost no voice.” Tan Bo explains. Jinan Qingqi, Qianjiang Motorcycle, motorcycle, etc. 9 Pearl River motorcycle companies have listed, and bike conversion kit companies in the country only 10 years of history, is the recent rapid development of six or seven things, the biggest listed companies are still waiting .

Since the bike conversion kit since the emergence of the industry are all chipping away toss up by private enterprise, but it has been subjected to heavy pressure, the future will continue to bear the various tests.

“The pressure will accelerate the industry consolidation, and ultimately the rest of the big brands, big business.” Lv Jianhong think. Committee of the China Bicycle Association, Bicycle Lu Jinlong cite a set of data: bike conversion kit number of firms in 2004, reached its peak in 2005, when the statistics over 2700, but a recent survey, the number has dropped to 1,000 the . Lu Jinlong think this is the result of industrial restructuring.

“In 2004, the largest annual output, but four or five million, now yield can reach 200 million, was almost the sum of the first 50 possessions can be seen the industry concentration is increasing, this is a good thing for the industry. “Lu Chin-lung said that in 2010 the domestic annual bike conversion kit2964.5 million, based on this figure, in his view, the future bike conversion kit enterprise scale annual output of 300,000 is reasonable.

“30 million capacity, if an annual output of 300,000, just 100 enough, but now there are a lot of domestic production in the 100,000 the following companies, so out certainly have to continue, more small companies will be forced to withdraw from the industry. “Based on industry analysis, Lu Chin-lung showed his point of view.

Restructuring electric motor need to be cautious

According to state regulations, bike conversion kit speed must be limited to within 20 kilometers per hour over the speed, you need to follow electric car electric moped electric motorcycle or management. It seems that defining bike conversion kit as standard, and therefore designated a huge market – the electric motor market. Many troubled bike conversion kit power steering motor companies expect the market. So, electric motor bike conversion kit market for some manufacturers and some investors, it is not a huge opportunity in the market?

Concerned about electric motorcycles and electric mopeds technical standards, have already announced. The surface it seems, bike conversion kit with the standard bike conversion kit, electric motorcycle electric motorcycle has standard, electric cars can be described as two entirely different sub-sectors, will receive a healthy development.

In fact, bike conversion kit in the country already has 120 million, is a huge industry, but the electric motor are not few. For the electric motor, Green Group, that the Ni Jie, the definition of electric motor should be the minimum speed limit, such as the minimum speed of not less than 60 km, and bike conversion kit is provided for a maximum speed limit are different.

Although the electric motor has its own standards, but in fact, who seems in some industries, electric motorcycles is difficult to do successfully. The most important reason is that there is no market. Why bike conversion kit to “fire up”, because the three points, one easy, the second is to save money, third is not the driving test.

But as a motor vehicle, electric motorcycle driving test must be, this is sufficient for the vast majority of consumers have been discouraged. Test a motor vehicle driver’s license, the cost will not speak, but also take some time to training. Second, the electric motor is no price advantage, and compared fuel motorcycle is not cheap. Buy a electric motor, generally get 4,000 yuan to 6,000 yuan, and this price can buy a motorcycle burning fuel, which power is strong, strong endurance, performance is stable. These do not have the electric motor, how can and fuel motorcycle competition?

Electric motorcycle business is difficult to survive another reason is the high registration threshold. According to regulations, electric motorcycles registered capital should be 80 million yuan or more, while domestic enterprises are bike conversion kit for small and medium private enterprises, out of 80 million yuan of funds to do test electric motor industry is difficult. Moreover, seeing there is no electric motor market, who would be willing to go to vote?

Real strength of the R & D, production of electric motorcycle, the motorcycle should be the original production company, they have sufficient funds, are familiar with the performance of high-speed vehicles, familiar with motorcycle manufacturing process, and are familiar with motorcycle customers. However, as a bike conversion kit practitioners say, even though they have the strength to do electric motorcycles, electric cars, but they are a stranger, do not understand and do not attach importance to electric cars. They do not have experience in the electric car veteran, looked down on bike conversion kit business, there is no interest in playing accompanied bike conversion kit business.

Another important reason comes from technique. According to the domestic industry’s practice bike conversion kit, speed of 50 km bike conversion kit, if you want to maintain the highest speed, the battery can only adhere to one hour. Want more than this time, there are insurmountable technical barriers.

The temptation to invest in lithium batteries

The four ministries issued “on the strengthening of bike conversion kit management,” which shook the whole bike conversion kit industry, the industry that standards will bike conversion kit industry chain – the battery industry to bring new opportunities.

Is expected to help policy subsidies

“120 million electric cars, more than 90% excessive.” Lifan Technology Co., Ltd. electric vehicle R & D department heads Tan Bo talk about his views, “if the strict requirements of the future rate of no more than 20 kilometers, that of the electric car industry , is lower rather than higher technical standards, it is very easy to do, and really easy ones to the future in technology, where the most tangled is the weight limit. ”

According to the 1999 release of “bike conversion kit general technical conditions”, bike conversion kit vehicle quality should be 40 kg. “Bike conversion kit from the weight of two parts, the body weight, and part of the battery weight, which is not easy to reduce the new standard is bound to stimulate corporate research and development of new lighter materials.” Tan Bo introduction, the traditional The bike conversion kit uses steel, if the weight, the steel thinning, thinning, although the weight will be reduced, but the quality is very difficult to pass, bike conversion kit of parts will be breakage. “Do is to fool people, the real solution is to use the new alloy, the industry standard will encourage enterprises to increase development of new materials.” He said, the steel can be used instead of aluminum-magnesium alloy, an aluminum-magnesium alloy foot twenty-three kg can replace the 9 kg of steel. Carbon fiber is lighter and more robust, but more expensive.

“The key is to use new materials and new batteries, the price will rise significantly.” Tan Bo example, an ordinary bike conversion kit if the price was 2,000 yuan, of alloy to reduce weight, the price will rise by 1 / 5 ~ 1 / 3 , that is, costs 300 yuan to 500 yuan, while the further use of lithium batteries, the price would go up $ 500, on the whole, designed to reduce the weight of the new electric cars, the price will be your $ 1,000.

The market price is not easy to accept. As the bike conversion kit market competition, a variety of components, costs are already transparent, the same type of car, will lose more than $ 50 each market, so the use of new materials, bike conversion kit sales is difficult to ensure.

However, it is not all gloomy news, coming a possible opportunity to help the lithium battery market.

“At present, China Bicycle Association, Bicycle Committee is seeking the state lithium battery electric vehicle sales business subsidies to help get to market faster lithium batteries to reduce the traditional lead-acid battery production caused by environmental lead contamination.” China Bicycle Association, Bicycle Committee Director Lu Chin-lung said. His argument is that, because reducing energy consumption and pollution, the state subsidies for electric cars are, then why can not lithium battery bike conversion kit to provide subsidies?

“Now our bike conversion kit, using 97% of lead-acid batteries, lithium batteries use only 3%, although not completely replace lead-acid batteries lithium batteries, but for businesses, lithium batteries have a huge space for development, electric car companies and battery research and development enterprises should seize the opportunity. “Lu Jinlong that, if the lithium battery electric vehicle subsidy per 400 yuan to 500 yuan, the basic lithium battery electric vehicles can make up the difference in the market, for lithium batteries to open the door to mass market, but once the rapid expansion of production scale, will further reduce the cost of lithium batteries.

Investment risk caused by technical problems

According to a statistics, China bike conversion kit lead-acid battery sales in 2009 already reached $ 12.2 billion from 2009 to 2011 compound annual growth expected to remain at 24%. Bike conversion kit to benefit from the rapid development of industry, battery industry, a thriving.

bike conversion kit production enterprises, has achieved more than listed. In the listing prospectus, these companies have focused rendering their bike conversion kit in the domestic market share and growth potential, to demonstrate that they can take a slice of the fast growing market.

June 11, 2007, days to first battery group to China stocks listed on the Main Board in Hong Kong as its business mainly in the production of electric cars environmentally friendly battery-based. Another battery giant – Chaowei Power Holdings Co., Ltd. 00951.HK also on July 7, 2010 successfully boarded the local capital market, raise funds amounted to HK $ 550 million. In the prospectus, the company announced in 2009, the domestic bike conversion kit with lead-acid battery market share of about 18.3%, the highest in the forefront.

In contrast, the domestic lithium battery company just to the fast lane. Suzhou Star Constant Power Co., Ltd. is the production of one of the largest lithium batteries, by Legend Capital, Institute of Physics, Chengdu Di Ao Group, a joint venture set up. On its Web site, the company also claimed that the domestic lithium battery product line, the largest investment companies. However, the company currently employs more than 500 people registered capital of 190 million yuan, with the leading enterprises in contrast to lead-acid batteries far. Industry sources pointed out that because of the scale is still relatively small, the lithium battery industry, there are significant investment opportunities.

“At present, lithium battery bike conversion kit sales is still relatively small, mainly because the user reason to buy for two reasons: first, because they live in high-rise buildings, lead-acid battery is too heavy, inconvenient to carry charge; the other is the fashion needs. “Deqing, Huzhou Lu Vehicle Co., Ltd., chairman of Lv Jianhong analysis, the next three to five years, the large-scale lithium batteries into the bike conversion kit market.

“However, in addition to electric vehicles using lithium batteries expensive than at present, there are still some difficult to overcome the shortcomings.” Tan Bo said lithium battery bike conversion kit can not start too fast, the load can not exceed 70 kg, that is, not with people. In contrast, lead-acid bike conversion kit is no problem loading more than 100 kilograms, can take people.

Zhejiang 001 Group, chairman of items that the lithium pine two other obvious shortcomings, first, the high cost, another point is the capacity of the explosive. “So much energy is released in one second, can not explode?” As the number of electric vehicle technology, inventors, pine familiar term in many areas of the industry, “lead-acid batteries as chemical batteries, has developed over 100 years , several decades before developing lithium batteries, is not stable. “He believes that investment in lithium battery high risk, one of his relatives had invested in tens of millions of lithium batteries on, but the business eventually because of technical problems difficult to overcome and shut down.

Popular electric bicycles, electric motorcycles most use DC motors, DC motor speed controller for many species. Electric vehicle controller core is the pulse-width modulation (PWM) device, and a sound controller, also has a battery voltage protection, motor overcurrent protection, power brakes, power display.
The size of the controller to power electric vehicles can be divided into high, medium power, low-power categories. Electric bikes use a low-power, cargo tricycle, and electric motors to be used in power and high power. With the motor from the sub, can be divided into brush, brushless two categories. About brushless controller, subject to current technology and cost constraints, the failure rate is higher. I believe that the brushless controller maintenance should be the main manufacturers. The applications have more brush control, is able to use similar controllers for direct substitution or maintenance.

July 21, will service the Shenzhen Metro Line 5 of the urban rail train, in the CSR Zhuzhou Electric Locomotive Co., Ltd. (hereinafter referred to as “CSR bike motor“) success off the assembly line. According to technical personnel, the Shenzhen subway train is the first time the use of domestic market traction electric bike motor, equipped with a CSR Zhuzhou bike hub motor Co., Ltd. successfully developed independently of the traction bike hub motor products. Reportedly, the bike hub motor than similar foreign products, cost 20% less cost.

Construction cost of about 80 percent of foreign imports

CSR bike hub motor propaganda minister Zhu Jianfei told reporters the South, according to a long, high-strength technology validation test, the company’s traction electric bicycle hub motor of the technical indicators and very similar products imported, the cost is equivalent to the latter 80% follow-up maintenance costs only about 50% of the latter.

As a subway train the “heart”, traction bike hub motor is the core technology elements of the train, the train is pushing the cost of acquisition and maintenance of key components. According to the CSR bike hub motor to the source, every subway train by a total of 16 installed traction bike hub motor calculations, the cost of similar imported products equivalent to 80% of the standard means cost savings for each train at least 30 million, saving maintenance cost of $ 1.6 million. The Shenzhen Metro Line 5 quantities of eight trains, the subway operator side in one fell swoop to save the purchase and maintenance cost of more than 15 million yuan.

“China-made new subway excellent traction bike hub motor design, the technical indicators have reached international level of similar products, and by virtue of small size, light weight, excellent insulation properties, etc., more cost-effective than the international product.” CSR bike hub motor Publicity Minister Zhu Jianfei told reporters.

It is understood that the Shenzhen line 5 using Y Q-190-5-type asynchronous traction bike hub motor developed in November last year. “Our bike hub motor to meet the environmental climatic conditions in Shenzhen and lines, power supply and gauge conditions, reached the world advanced technology level.” Zhu Jianfei said. In addition to the quality of clearance, CSR bike hub motor with similar products, compared with a clear price advantage, is expected to slightly better in terms of competition.

Break the international monopoly of imported brands

Since 1984, successfully developed China’s first YQD -300 electric locomotive with AC traction bike hub motor has CSR bike hub motor in the year to promote technological breakthroughs in recent years, metro bike hub motor to speed up the localization process. And Shenzhen Metro Line 5 electric bicycle hub motor of similar products YQ -190-3 type bike hub motor landing in Beijing in December last year Fangshan Line subway. This year, the CSR Zhuzhou bike hub motor to provide traction electric bicycle hub motor project as well as Shanghai Metro Line 1, Shenyang Metro Line 2, Chongqing and Guangzhou Subway Line 6, 1,2,8 subway line.

“This year also includes the first major breakthrough into the European market, Izmir, Turkey to sign the light rail project, and volume manufacturing to 16, which is representative of the South China car bike hub motor bike hub motor subway traction vehicle with the European debut . “CSR bike hub motor to the reporter concerned. In addition, exports of CSR electric bicycle hub motor vehicles to maintain Singapore’s subway project supporting the development of electric bicycle hub motor, has achieved mass production, breaking the foreign giants for high-end metro and light rail traction system monopoly.

According to reports, South car sales this year expected to reach last year’s 2.5 times. And gradually replaced by a single manufacturer to create a combination of physical transformation and investment.

bike conversion kit for transport

Posted by on January 1, 2022 Comments Off on bike conversion kit for transport

bike conversion kit is the most common means of transport, is now able to buy everywhere, but the style and beautiful and light, as long as you want to buy, Na Zhaoqian to which the supermarket can be easily bought ride. In today’s traffic congestion is very severe cases, the cycling trip is a wise choice.

In the Great Northern Wilderness, I will not ride, even if someone took my car I can not go up (now still can not go it ^_^)。 After returning to the city, I Baijiazhuang Plant that is near the bulb before the bulb factory work, Chaoyang District. At that time I lived in the South of simple body work building, not far from the factory. We are morning and evening classes to work two shifts, early morning before 6:00 to duty, night shift will have 10 points to go home.
In order to rely on more than a moment when the early shift bed, I began to learn to drive a three-day course.

I heard my neighbors brother ride to school, take the initiative to lend me an old woman car, and enthusiastic and became my coach. Tightly clutching his back after the hanger, so I get to ride forward, rest assured, at first I did not dare look to the future, he kept looked at the ground, so the car will be a time to the side of the dump, thanks to a neighbor Big Brother’s escort, I almost can not Shuaiguo wrestle the riding of forward. Three days later, my riding skills have come a long way to grow, I can separate the two wheels along the road that circle around the riding too fast. Excited I was almost to the world declaring: I will eventually ride it! (Not included here pulley ah ^ _ ^)

Learned to ride, but the car where? The planned economy era, what to buy tickets should, bike conversion kit votes, sewing machine vote counting in a variety of furniture are the most scarce of the time. We factory pumping a few tickets every year, is the drawing of lots in accordance with the workshop team decision. The first time I hand a little bit smelly, nothing to catch. Finally caught a second bike conversion kit votes, so happy I can not wait to go home to my mother with me to buy a car. I remember when the Kanto shop near a bike conversion kit shop, I just bought a life where the first one bike conversion kit, the Flying Pigeon female car, 26’s, dark green color is very pretty, I I liked it, remember it took like 154 dollars. So the next day I started cycling to work, and daily round-trip time was reduced by nearly an hour it ^ _ ^.

Perhaps it is getting too much, I am pleased the less than six months, one day, a colleague to take my car to work, the results of a semi-tractor on the road and collided into my car and knocked out of shape, both wheels are almost twisted into a twist, but fortunately she were not injured. She had said he would pay me a new car, but she later changed his mind and refused to pay my car, I only agreed to repair. But my brother is that neighbors bike conversion kit Repair shop, shaking his head after he saw the car that did not fix it, even if the repair was able to ride away and will also affect the quality of life of the car. So I had to find that my colleagues once again express my meaning, I have a new car requires compensation, but also betray her, and insisted on the tube not pay car repair. She’s not unreasonable annoy me, I found the workshop director to complain, and the director is a very reasonable man, he and the secretary of the workshop repeatedly to do the work that my colleagues, she promised to pay me a new car.

So my first one bike conversion kit to come to an end with this result. Succeed it is a black, Flying Pigeon, 26 female car, the car has been accompanied me to the end of 2003, big day in front of my house was stolen by a thief. Now I travel all take the bus into the subway, every block on the road, I will miss the companionship I did get the bike conversion kit to …

he survey of electric bike conversion kit

Posted by on January 1, 2022 Comments Off on he survey of electric bike conversion kit

According to the survey of electric bike conversion kit has become the sale’s biggest problem, and serious problems to consumers, the convenience of electric bicycles as a result of the problem because the battery is not convenient, then the convenience of electric bikes on the greatly reduced, then consumers in the purchase of electric bicycles The process should be noted that the battery problem?

Primarily concerned with the battery capacity and voltage indicators. Electric vehicle battery is the main power source, the battery voltage and capacity is a combination of different combinations, electricity capacity, power, driving range so that the difference in the price are 2 to 3 times. So in the time of purchase, to find out the buy bike conversion kit in the end is how many volts, how many amps. Under normal circumstances, bike conversion kit 48-volt 20-amp 36 volt 10 amp than the fully charged one-time driving distance is longer, in general, the battery capacity, the greater the power, the price corresponding to high.

Second, we must ask electric vehicle warranty warranty period and specific content. Businesses are generally committed battery warranty for one year, but businesses said Paul, “year” is divided into periods of dollars: generally refers to the date of purchase, quality problems within six months of battery replacement, replacement of six months to a year maintenance of the old battery, continued to use the issue to a year after the business is not responsible.

Therefore, consumers in the purchase of electric vehicles and businesses time to negotiate a good battery specific warranty periods and the corresponding content, and indicated on the warranty card to avoid consumer disputes.

Finally, select the brand, service and reputation. Brand, service and word of mouth publicity is the best way to electric cars. Consumers buy not only to choose good quality car battery, but also than the service than the brand, pay attention to whether the product has a service point in the region, in the quality of service, reputation in the word of mouth how to fail the future of electric cars When, in the shortest possible time to be resolved.

Whether it is the battery or are in the purchase of electric bicycles should be noted, carefully follow the principle, and companies that focus on quality, focusing on after-sales service, so that electric bicycles can be a real blessing consumers!

Small and medium-range torque torque (20Nm usually less) small medium large, full range

Low speed range (usually in the following 2000RPM, high torque motor is less than 1000RPM) high (up to 5000RPM), DC bldc motor can even reach 1 to 2 million r / min

Main control position control diverse intelligent control, position / speed / torque mode

Vibration at low speed smoothness (but with a sub-type of drive can be improved) is good, runs smooth

Accuracy is generally low, higher high when the sub-type drive (depends on the specific feedback device resolution)

Torque-frequency characteristics of high speed, good torque down fast torque characteristics, features hard

Overload overload feature will be out of step 3 to 10 times overload (short)

The majority of open-loop feedback control mode, the encoder can also be connected to prevent the loss of step closed loop encoder feedback

Encoder Type – Optical Rotary Encoder (Incremental / Absolute), resolver-based

Response speed is generally fast

How equipped with bldc motor controller?

According to the motor current, with the greater than or equal to the current drive. If you need a low vibration or high accuracy, can be equipped with a sub-type drive. For high torque motor, as with high voltage drive to get good high speed performance.

2 phase and 5 phase bldc motor What’s the difference, how to choose?

2-phase motor and low cost, but the larger the vibration at low speeds, the torque at high speed down quickly. 5-phase vibration motor is smaller, high-speed performance, compared with 2-phase motors, high-speed 30 to 50%, in some cases replace bldc motor.

When to select a DC servo system, servo it What’s the difference?

Bldc motor into a DC brush and brushless motors.

Brush motor, low cost, simple structure, starting torque, wide speed range, easy control, the need to maintain, but easy to maintain (for brushes), generate electromagnetic interference, the environment requirements. Therefore, it can be used for cost-sensitive general industrial and civil applications.

Brushless motor, small size, light weight, large output, fast response, high-speed, inertia is small, smooth rotation, torque and stability. Control complex, easy to implement intelligent, flexible way to their electronic commutation, the commutation can be square wave or sine wave commutation. Motor maintenance-free, high efficiency, low operating temperature, electromagnetic radiation is very small, long-life, can be used in various environments.

AC bldc motor is brushless motor, is divided into synchronous and asynchronous motors, motion control in general are currently with the synchronous motor, its power range, can do a lot of power. Large inertia, the maximum rotation speed is low, and with the power increases rapidly reduced. Therefore suitable for low speed applications running smoothly.

The motor should pay attention to the problem?

The power to run before you make the following checks:

1) the appropriateness of the supply voltage (overvoltage is likely to cause damage to the driver module); for the DC input of + / – polarity must not be wrong, the motor drive controller on the model or the current setting is appropriate (do not start too);

2) control signal line connected, secure, industrial site is best to consider shielding (such as the use of twisted-pair);

3) Do not put the need to take the start line all connected, only the most basic system even as, well, then gradually connection.

4) The grounding method must be clear, or the use of float is not connected.

5) began running half an hour to closely observe the motor state, such as the movement is normal, sound and temperature, and found the problem immediately stop adjustment.

leaf Super model car contest rules, no restrictions on the use of motors, as long as the right, players can choose the hub motor. Having an expert auto locksmith that you can call anytime is also a good
thing to have, though not necessary. If you are having a hard time finding an auto lock smith you can find an auto locksmith company in West Palm Beach FL here.So how to choose the right motor it? Oaks from little acorns, the motor is a fundamental part of the model car, the motor will have a direct decision model cars will eventually run fast? When you want to find out how much your car is worth can be a useful resource. With an office in San Diego they can help you get you paid quickly for your car. AC and DC motors are generally divided into two, thanks to battery-powered, combined with a model car of this level, it is generally used as the drive hub motor.It may be considered an exception to the brushless hub motor, and it is essentially a AC motor. The hub motor’s basic principle is nice and simple, there is no nonsense. Fixing a car can be difficult when you don’t have the right parts, but you can easily get new Bentley Parts from leaf Car Parts.

Specifically, the optional hub motor in the following categories: general motors, coreless motor, brushless motor.

1 General Electric. Is the most common, the most common motor.

2. Coreless hub motor. Coreless DC motors are permanent magnet, servo motor, the main difference with the ordinary use of the motor is coreless rotor, also called hollow cup-shaped rotor. Coreless motor compared with ordinary motor, has the following advantages:

a. higher energy conversion efficiency (a measure of its energy-saving features of indicators): The average efficiency of 70% or more, some products can reach more than 90% (normal 15-50% in the core motor);

b. Activate the brake quickly, fast response: mechanical time constant is less than 28 milliseconds, some products can reach 10 ms or less, the recommended area of ​​high speed running state, the speed control sensitivity;

c. reliable operation stability: adaptive ability, their speed fluctuations can be controlled in less than 2%;

d. less electromagnetic interference: the use of high-quality brushes, commutator structure, change the spark is small, can avoid the additional anti-jamming device; energy density: core motor with the same power compared to its weight, volume reduce 1/3-1/2; speed – voltage, speed – torque, torque – current standards such as the corresponding parameters presents a linear relationship.

Coreless motors are divided into brush and metal brush, brush carbon brush of high melting point than the metal resistance, strong overload capacity, peak current for frequent occasions (start / stop operation, forward and reverse operation, etc.)

3.brushless motor. Brushless motor stator windings made of three-phase symmetrical multi-star connection, with three-phase asynchronous motor is very similar. Stick with the motor rotor has magnetized permanent magnet, in order to detect the polarity of the motor rotor, the motor that has the position sensor. Drive from the power electronic devices and integrated circuits, etc., and its function is to: Accept the motor start, stop, brake signal to control the motor start, stop and braking; receiving position sensor signal and inversion signals used to control the reverse change the bridge off of the power tube to produce a continuous torque; accept the speed command and speed feedback signals used to control and adjust the speed; providing protection and display, and so on.

brushless motor and other motor comparison:

Advantages of brushless, brush motor on the brush to avoid damage to the defect, long service life. Fast speed, big power.

Disadvantages brushless machine load fluctuations may not respond, and this model contest for the motor load required to withstand very large fluctuations, the use of brushless motor may be (actually bound) appears the phenomenon of motor suddenly stopped. And brushless motor voltage range of smaller, less torque, control complexity, the current large to meet the requirements of the Japanese games do not brushless motor. So the basic rule out the brushless motor.

The above point of view, the most suitable for the game is hollow cup hub motor, had previously conducted experiments on the corresponding features coreless motor has a very profound impact. However, the coreless motor has its drawbacks, first of all is the price, coreless motors are more sophisticated motor, prices are generally very expensive, but also hundreds of cheap domestic one, expensive as MAXon, FAULHABER, thousands of one. With four-wheel drive, for example, the motor would take thousands, taking into account what the backup, put quite big ah. The other is the hub motor resistance than ordinary rough ah, improper use, then easily out mechanical failure, such as brush burn, the drive shaft off, I have broken several a night, a few thousand dollars gone ah.

Therefore, most of the teams, the more appropriate is the ordinary motor, the cheap, rough-resistant, pressure is good. Ordinary hub motor can be divided into several levels, the general classification by motor diameter, such as the RC130, RC260/RC280, RC380, RC540, and so on. Freescale is the RC380 motor racing competition organizing committee to provide Renesas level is RC260 motor. Generally the larger motor, the greater the power, the same level of motor parameters are also different.

If you pick it? Example. Suppose I want the rented car that can reach up to 4m / s speed, wheel diameter of 45mm, the transmission ratio 1:6, then the motor speed at least 10000r/min, taking into account the redundancy of the motor rated speed to achieve 14000r/min, only more but, even taking into account work by the overpressure, ie 6V motor in 10V (8 * 1.2) voltage, is higher than the motor rated speed 8000r/min, then you can visit royaldrive. Another important parameter is the power, experience, 1kg 3w about model car with the motor on it, of course, the power is the bigger the better.

Japan “MCR God” Haruo Shimazu car will use a committee of four to provide the motor (Mabuchi’s RC260-18130), as shown below, you can reach 3.8m / s average speed. And in 2009, Huazhong University of Science uses four RC-280 motor. Thus, an ordinary motor, as long as the design is reasonable, selection is correct, we can achieve good results. Select the motor, it is best to buy the regular manufacturers such as Johnson Electric, yushan motor, etc., generally corresponding specifications for reference, the quality is also reliable. After a long tiring day, your cars is just like you, it wants to have a best wash it deserves. You can bring in best pressure washers for your car to make it presentable and cool again.
