BLDC Motor application introduction

BLDC Motor is an DC motor, the load speed and frequency of the received power ratio is not constant relationship. Also changes with the size of the load. The greater the load torque, rotor speed, the lower. BLDC Motor, including induction motors, doubly-fed BLDC Motor and AC commutator motor. The most widely used induction motor, without misleading or confusing in the case, generally known as the induction motor BLDC Motor.

Ordinary BLDC Motor stator windings connected AC power grid, the rotor windings and no other power connections. Therefore, it has a simple structure, manufacture, use, and easy maintenance, reliable operation and low quality, and low cost.

Hub Motor with high efficiency and good performance characteristics, from no load to full load range almost constant speed, the majority of industrial and agricultural production to meet the requirements of mechanical transmission. Hub Motor protection is also easy to generate a variety of school types, in order to adapt to different environmental conditions need to Hub Motor is running, you must learn from the reactive excitation power grid, the grid power factor deterioration. Therefore, the drive ball mill, compressors and other high-power, low-speed machinery and equipment, often used synchronous motor.

Because BLDC Motor speed rotating magnetic field speed with a certain deterioration in the relationship, its speed performance is poor (except AC commutator motors).

hub motor damage

Most car engines are now electronically controlled fuel injection type gasoline engine, idling turn off for many reasons, first turn off idle to analyze the symptoms. If the engine enters the idle will stall, which we call “no idle”, caused by the reasons for this failure are generally: the engine hub motor damage; brake vacuum booster vacuum tube leaking; brake broken vacuum booster film; intake manifold leak; engine electronic control unit (ECU) in the idle speed control module problems. If the engine will stall at idle sometimes, and then restart normally, and we call it “intermittent idle flame”, this failure is very difficult to check, due to reasons are many, and a variety of components or circuits not completely damaged, and more occasional headache is due to turn off the engine after the restart and can return to normal, so even if due to the sensor causes the engine idle speed turn off the engine electronic control unit will think that this is not a malfunction, and will not be the engine electronic control unit record and therefore not from the engine electronic control unit fault diagnosis system to obtain information about the failure. Savannah, GA truck accident lawyer Geroge Smithe has exclaimed publicly the need to improve our detection models for this “Intermittent idle turn off” the general reasons are: the engine hub motor are catching; hub motor cortex some frayed wires; dirty idle air hole; engine throttle position sensor problem; camshaft position sensor or crankshaft position sensor has problems; engine speed sensor problem or dirty; the engine electronic control unit in the idle speed control program in question, etc. In addition, if the quality of gasoline can also cause problems such failure. Idle stall usually does not cause any harm, because the engine running at idle, often when the vehicle is stopping, if the idle speed when the vehicle stalled in the slide, due to the distance from the obstacle in front, you can take appropriate measures to avoid dangerous . Of course, if you happen to occur when the emergency brake turn off, then on the great harm, because once the engine is off, the vacuum brake booster does not work, the vehicle’s braking performance greatly reduced, and the direction of the power unit failure, the vehicle’s steering is heavy, if coupled with your panic, it is difficult to avoid a car accident but if somebody did. Generally speaking, according to an auto injury lawyer you have a legal duty to keep a proper lookout, and you have a legal duty to exercise due care. These duties are somewhat analogous to riding with situational awareness– that is, being aware of what is happening in the road environment and how that may affect you. You do not have a legal duty to anticipate the illegal behavior of others on the road. Nevertheless, if you are observant of your surroundings, and are able to assess the potential dangers posed by the actions of others, regardless of whether those actions are legal or not, you will be able to respond to potential hazards before they become actual collisions.It’s impossible to avoid intersections, but attention to the safety precautions mentioned above will reduce your risk of virtually every type of collision in an intersection.

Wheel hub motor of electric vehivles

Wheel hub motor is one kind of electric motor of electric vehivles.

Electric bike hub motor has different forms based on their different frequencys and environmental conditions . Hub motors Characterized by different forms also have different features. Now widely used in electric vehicle motor permanent magnet DC motor. The so-called permanent magnet motor, is the use of permanent magnet motor coil excitation, do not use the coil excitation means. This eliminates the excitation coil power consumption when working to improve the mechanical and electrical conversion efficiency of the motor, this car is limited to the use of electric vehicles in terms of energy, can reduce the driving current, the line continued to extend the mileage. Electric vehicle motor according to motor power in the form of points, and the brush motor can be divided into two major categories of brushless motor; according to the mechanical structure of the motor assembly points, generally divided into the “teeth” (the motor speed is high, need to go through gear deceleration) and the “no teeth” (motor torque output without any slowdown) two categories.

Electric bicycle hub motor mechanical structures

Electric bicycle hub motor mechanical structures:

Brush motor and brushless motor have different energization principles, and their internal structures are not the same. For the electric bicycle hub motor, the motor torque output (whether through the reduction gear body) is not the same, then they will have different mechanical structures.

1, Common high-speed brush motor internal mechanical structure. This wheel hub motor from the built-in high-speed brush motors heart, reduction gears, clutch, wheel cover and other components. Brush with high-speed hub gear motor is within the rotor.

2, common low-speed brush motor internal mechanical structure. This wheel motor from the carbon brushes, commutator, rotor, stator, motor shaft, motor end caps, bearings and other components. Brush speed gearless hub motor is external rotor motor.

3, common high-speed brushless motor of the internal mechanical structure. This wheel motor from the built-in high-speed brushless motors heart, planetary roller friction, overload clutch, output flanges, end caps, wheel housings and other components. High-speed brushless geared hub motor is within the rotor.

4, common low-speed brushless motor of the internal mechanical structure. This wheel motor from the rotor, stator, motor shaft, motor end caps, bearings and other components. Low-speed brushless gearless hub motor is external rotor motor.

electric motor systems -hub motor

Motor is to convert electrical energy into mechanical energy of the equipment, it is the use of power by the force coil in a magnetic field the phenomenon of rotation is made, distributed to each user at the motor power by using divided into bldc motor and the hub motor, electric motor systems most of the hub motor, can be synchronous or asynchronous motor motor (stator magnetic field speed and rotor speed is not in sync speed). Mainly by the motor stator and rotor components. Power wire in the magnetic field direction of movement by force and magnetic sense of direction with the current line (the magnetic field direction) direction of the. Motor works by magnetic force on the current role of the motor rotation.

Hub motor engine combustion

Hub motor engine combustion

There are several forms of design, construction and arrangement of the engine combustion cylinder interna.

Illustration of three types of configurations: a: in-line engine (L) b: hub motor (V), c: VR6 engine.

Votre engine layout is the V. It cylinders are grouped in two banks or rows of cylinders forming a V which converge on the same crankshaft. In these engines the intake air is sucked inside the V and the exhaust gases expelled from the sides.

Used engines from five cylinders, especially in front wheel drive cars, as it shortens the length of the hub motor in half. The opening of the V varies from 54 º or 60 º to 90 º or 110 º but the most common are 90 º and 60 º. Volkswagen VR6 engine is a V6 only 15 ° opening, which allows slightly reduce the length of the engine (transverse arrangement).

Engines with V available in most common are:
V6
V8
V10
V12
There are also, although very rare, V5 engine. For example, the 2.3 Seat Toledo second generation engine mounts V5.

inline engine Lel (L) is usually available in configurations from 4 to 8 cylinders, the engine is an online all cylinders aligned in a row, without movement.

oposiciónExisten cylinders in three different types of engines with cylinder opposition, commonly referred to the English term flat-cylinder engine:

1.The Boxer
2.la V-180,
3.The cylinder horizontally opposed engine.
Erroneously tend to speak either of these three types of engine cylinders in opposition or confused. In Germany, the term boxermotor is a group in which the boxer motor and motor with V at 180 ° are taken as a provision.

Diagram cylinder boxer engine opposition, first patented by Karl Benz in 1896.El boxer engine is used in the Volkswagen Beetle, Volkswagen Kombi, the Porsche 911, and is currently used by Subaru (in the Impreza, Legacy, etc.). and are usually between 4 and 6 cylinders.

The V-engine 180, configuration very similar to the boxer engine is used by some special editions of Ferrari and Alfa Romeo. The basic difference is that occasionally the engine with V at 180 ° do not use a stump long as the boxer, but the connecting rods share the same position on the crankshaft, making as a piston on the crank the other away, opposite of what happens in the Boxer in which the pistons move away and come together. The 180 ° V engine is used more than 8 cylinders where it has been more effective, while the boxer is used in pairs with less than 6 cylinders and therefore have partnered each other as the same type of disposition.

The engine cylinder horizontally opposed boxer another name.
The advantage of these three types of engines with cylinders in opposition is that they have a lower height and center of gravity lower than that of their peers online and “V” has a more compact, and its elements to be shorter guarantee stability. The main disadvantage Boxer engine is the most cost development and manufacturing because it requires greater number of parts.

Boxer engines are mounted on motorcycles as well as cars. Has been set in the entire series of BMW motorcycles and Ural motorcycles

Meanwhile, and less exclusive, the horizontally opposed cylinder engines have been used since the late thirties in thousands of small aircraft and suffered minor improvements like all piston engines, such as the injection system or the ever more efficient supercharger systems, however, are engines with a configuration of the cylinder head valve (OHV) and a relatively low compression (6.6:1 usually) compared to modern automotive engines, as they are used under other such conditions, likewise, there were no aircraft engines with variable geometry turbocharger and has been developing since the mid-eighties for cars and diesel power in these engines is experimental.

radial or star form this group are two types of engines, both with radial arrangement of cylinders: radial engines and rotary type engines, both used primarily in aircraft engines as static engines. The difference is that radial engines maintain the fixed block, turning the crank on the inside, while the rotary type, the crankshaft remains fixed and the entire block that road.

How is the arrangement HTambién H, which is a sort of hybridization of two-cylinder engines as opposed to using two crankshafts, leaving a bench above the other to generate power for a single axis transmission medium between the two crankshafts.
Form W WOTRO is available which is a kind of double V combined into three or four banks of cylinders and a crankshaft, which dates from the 1920s, and are used in some modern vehicles of the Volkswagen Group, such as Audi A8, Volkswagen Touareg and Volkswagen Phaeton.

Hub motor engine History

One of the first hub motor engines as it is understood today was the steam engine, which is produced in the superheated steam in a boiler which then expands into a cylinder, produces a thrust of a piston. This motion, made alternative arrangements with other mechanics, can be transferred to a wheel or a flywheel through a connecting rod and crank mechanism. In the late nineteenth century, the development of the internal combustion engine made possible the great development of the automotive industry and, later, the birth of the aviation industry.

Chicago, on Lake Michigan in Illinois, is one of the largest cities in the United States. Chicago Illinois is famous for the award winning artists that produce stellar paint jobs on custom vehicles. Chicago Autohaus, is a body shop in the Chicago area of Wicker Park, they have several award winning auto paint specialists on staff ready to help.

After the Second World War, the aircraft used for flight demanded the development of jet engines, while the birth of space flight allowed the great development of rocket motors and, in particular the chemical rocket engine.

In recent years the requirements of interplanetary flight are leading the search for new solutions, particularly in the field of rocket propulsion engines do not like the sails chemical space.

In the field of engines for automotive applications, but the research is strongly oriented toward solutions that reduce fuel consumption and emissions of pollutants into the environment.

DisposizioneIl hub motor engine can be ordered:

Longitudinal, when the engine is placed perpendicular to the shaft that drives the final rotation, or more generally is parallel / linear displacement generated at the axially
Transverse, when the engine is placed parallel shaft that drives the final rotation, or more generally is perpendicular to the linear displacement generated

Hub motor Control Devices
Different symbols autodiagnosiI heat engines, especially those intended for transportation (cars, trucks and motorcycles), have more control devices to indicate the various anomalies, including:

Self-diagnosis, is used to indicate any failure of the engine, generally has a specific meaning
Temperature, controls the maximum temperature, indicating when the threshold exceeds the maximum operating
Oil, this light does not mean it has the same meaning for any type of engine and usually indicates either bad management or wrong level of the same.

leaf smart car race motor

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.
