What kind of common electric vehicle motor?
Electric vehicle motor is generally DC motor, DC motor according to whether the internal use of permanent magnet, divided into permanent magnet motor and series motor two categories. The rotating part of the motor is called the rotor, and the non-rotating part is called the stator.

Characteristics of permanent magnet motor
The rotor or stator of a permanent magnet motor has a permanent magnet, and the other is wrapped with enamelled wire. A permanent magnet motor with the same power saves more power than a series motor.

Permanent magnet motor
The magnet of permanent magnet motor is afraid of high temperature. The quality of the permanent magnet motor will be demagnetized when the ambient temperature reaches 110°, and the better one can be demagnetized to 140°.
On the market, permanent magnet motors are commonly used in electric bicycles with a power of 180W-250W and electric motorcycles with a power of 350W-500W.
Series motor features
The rotor and stator of the series motor are wrapped with enamelled wire. Because it does not contain magnets, there is no demagnetizing phenomenon. Series motor belongs to brush motor. On the market, the common motor power of 400W-900W freight three wheels are used by series motor.
