What are the types of electric motors for electric vehicles and what are the differences between them?At present, electric motors of electric vehicles are usually divided into three types: brushless high-speed motor, brushless low-speed motor, and brushless low-speed motor.The following xiaobian specific understanding.

What are the types of electric motors for electric vehicles and what are the differences between them?

1. Brush high-speed motor.The motor has high efficiency, strong ability of overloading and climbing, large starting torque, and output power after decelerating through the change gear device, with noise.

2. Brushless low-speed motor.No reduction gear, maintenance - free, noiseless advantages.However, the controller is complicated, with large starting current and poor climbing ability due to overload.

3. Brushless low-speed motor, no reducer gear device, simple structure, low cost, poor overload capacity at the beginning and high power consumption.Due to the high speed of brush high speed motor (3000 RPM for high speed motor, 500 RPM for low speed motor), large torque power needs to be output through reduction gear device after reduction, so the noise of brush high speed motor is relatively larger than that of low speed motor.

Miscellaneous brand cars, low-grade cars, assembly cars, in order to reduce the cost of more use of low-speed motor, you in the purchase of electric vehicles, do not because the motor sound slightly louder and the wrong choice.High-speed motor car price should be in 2000 yuan of above, low-speed motor car price is in 2000 yuan the following, generally the user purchases should be more careful, don't cry because it is the motor no noise, no wear is good, the main indicators is the efficiency of machine and power performance, low speed motor weakness is low efficiency, magnetic magnetic steel easy to fade, heavy weight, performance is poor, cycling, such as large power consumption.

Still want to remind, when buying electric car electric machine, still choose well-known brand, can assure the quality of the product better so.
