Synchronous motors can be divided into permanent magnet synchronous motors, hysteresis synchronous motors, and reluctance synchronous motors based on the different magnetic fields. Asynchronous motors include induction type and AC commutator type, among which induction type asynchronous motors can be further divided into three-phase asynchronous motors and shield pole asynchronous motors.

Electric motors have high reliability, and their core components such as the stator and rotor are well-designed, resulting in a long lifespan and extremely low failure rate. During the operation of the motor, the pressure, vibration, and noise are all very small and almost negligible, ensuring its stable and reliable working performance. Electric motors have no smoke, odor, and low noise during operation, making them an environmentally friendly driving method.
