Electric vehicle motor all universities ask, from principle, classification to application
The electric vehicle motor has different forms depending on the environment in which it is used and the frequency of use. Different types of motors have different characteristics. Permanent magnet DC motors are commonly used in electric vehicle motors. The so-called permanent magnet motor means that the motor coil is excited by a permanent magnet, and the coil is not excited. This saves the electric energy consumed during the operation of the excitation coil and improves the electromechanical conversion efficiency of the motor. This can reduce the running current and extend the mileage of the electric vehicle using the limited energy of the vehicle. Electric motor motor is divided into two categories according to the power-on form of the motor. It can be divided into two types: brush motor and brushless motor. According to the mechanical structure of the motor assembly, it is generally divided into “toothed” (high motor speed, need to go through the gear Deceleration) and "no teeth" (motor torque output does not undergo any deceleration) two categories. An electric motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor.
