lead-acid electric bike battery

Posted by on January 14, 2022 Comments Off on lead-acid electric bike battery

One pair of lead-acid electric bike battery business of the special rectification action in the country’s largest production base bike conversion – Jiangsu, causing a chain reaction.

Electric car “sit in prices,” four or five hundred

“The electric bike battery I bought earlier this year, or a $ 500, now 700 yuan of how to become?” July 4, in Nanjing Ruijin Road, a brand of electric automobile electric car shop floor, the public dissatisfaction Chan asked shopkeepers.

Reporters visiting the market in more than 10 shops, each shop owner in the consumer, “Mozuipizai.” “After all, because electric bike battery in the price.” One owner said, the state strengthened the intensity of lead-acid electric bike battery after remediation, electric bike battery began to demand, “this two-day media a report, electric bike battery factory ‘ride in prices’, each up $ 20 a Electric cars use four electric bike battery, a rose is 80 yuan. ” Reporters asked a number of shops that sell, an electric car electric bike battery is good is 1,000 yuan, the poor have five 600.

The owner said, yesterday morning, the boss put the ready cash around to buy electric bike battery, “I heard that this month will be going up now are not we save point, it could take money can not buy, these days can only be changed supply channel. ”

electric bike battery prices, pushed up the price of electric cars. In a province famous brand of electric car shop, the boss out price list to reporters, “honest”: “In mid-June, we all sales shop in Nanjing uniform prices, the average one or two hundred.” But one industry price list after reading quietly told reporters, “The price of small cars rose two or three hundred dollars, increased more than 400 yuan.”

One has been engaged in the sale of electric vehicles for many years the owner said that from 2007 to 2009 the price of electric vehicles all the way up, we all make money on the entire chain. After 2009, rapid expansion of production capacity, the average price has declined by 400 yuan. “Now the electric car brands are doing the final assembly of integrated accessories factory prices rise, the pressure will certainly pass back.”

Reporters look at different stores that market, different brands, price increases are not the same, some tens of dollars, and some two hundred dollars. Suzhou, a brand of electric car dealers say,mainly a small number of big brand distributors and brand agents, their resilience and weak, big brand distributors in order to maintain sales volume, prices rose less up to less. “Electric bike battery prices, car prices have a good reason brewing end of this month, the price of electric cars will certainly continue to rise.”

bldc motor winding open circuit causes and treatment

Posted by on January 14, 2022 Comments Off on bldc motor winding open circuit causes and treatment

bldc motor winding open circuit the motor does not start, three-phase current imbalance, abnormal noise or vibration, temperature exceed the allowable value or smoke.

Winding open circuit due to poor welding or the use of corrosive fluxes, welding and then not cleaned, it may cause solder pot or loose; by mechanical stress or collision coil short-circuit, short circuit and ground fault also can lead burning, and burning in of a few wires in a short circuit or a few wires, the other a few wires as current as temperature rises, causing fever and winding circuit. Generally divided into disconnected end of one phase winding, inter-turn short circuit, parallel circuit branch office, multi-wire and burned in an open circuit, broken rotor cage.

hub motor short circuit causes:
1, when in the repair and maintenance problems touched off or manufacturing quality.
2, the winding of the components, pole (phase) winding and the lead group and the first welding wire and other wire bad, long-running hot sealing off.
3, by mechanical force and electromagnetic force or pull off the winding damage.
4, short circuit and the ground turns white sometimes cause severe burning or winding fuse and so on.

hub motor short-circuit approach:
1, open circuit at the end, the connection is completed weld, wrapped in insulating material, put pipe insulation, banding is good, and then dried.
2, as inter-turn winding, white short-circuit and ground and other reasons caused serious burnt windings should generally be replaced with new winding.
3, the open circuit point in the tank, is a small break to do emergency treatment, the use of groups out method to identify breakpoints and the Ministry of winding down its connected and insulated qualified to use. If your business is a buy and sell or something, you might need motors can be risky and dangerous.
4, the cage can be broken rotor cage welding, cold-connection of a repair or exchange.

Why hub motor out of step?

Posted by on January 14, 2022 Comments Off on Why hub motor out of step?

1, hub motor rotor of the stepper motor acceleration is slower than the rotating magnetic field, that is lower than the phase velocity change arising. This is because the lack of input electrical power, generated in the stepper motor torque can not make synchronous rotor speed to follow the stator magnetic field rotation rate, causing loss of step. And any high frequency than when the frequency is bound to work out of step. This illustrates the step-step motor drag is not enough. Once the reduced load, or increase the winding excitation current, it is possible to overcome the loss of step.

2, hub motor rotor speed is higher than the average of the average rotation speed of the stator magnetic field. Then the stator excitation power for longer periods, than the time required for the rotor step further, the rotor step process to get too much energy, resulting in pediment and the backlash of the swing oscillations. When severe enough to cause oscillation of step.
