Electric motors are important electromagnetic devices that provide power to various devices through the conversion of electrical and mechanical energy, and are an indispensable part of modern society.

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.

A motor, also known as a motor, is a device that converts electrical energy into mechanical energy through electromagnetic action. Electric motors convert or transmit electrical energy based on the law of electromagnetic induction. According to the working principle, motors can be divided into electric motors and generators.

The motor has good controllability, and the speed and torque of the motor can be easily adjusted by controlling the voltage and current. Meanwhile, the maintenance of the motor is relatively simple, with fewer parts and no need for lubrication, making maintenance work easier.
