An electric motor, also known as a motor or electric motor, is an electrical device that converts electrical energy into mechanical energy and can be used to generate kinetic energy to drive other devices. There are many types of electric motors, but they can be roughly divided into AC motors and DC motors for different applications.

1. Main components of the electric motor
The electric motor consists of the following parts:
The machine base is equipped with a stator, rotor, and other components.
The stator consists of three parts: the stator core, the stator winding, and the machine base. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic field lines in the rotating magnetic field and generate (output) current.
The function of the rotor part is to obtain rotational torque under the action of a rotating magnetic field. It is mainly composed of rotor winding, rotor iron core, rotor shaft, fan, etc. According to their different constructions, rotors are divided into two types: squirrel cage and wound rotor. The rotor of medium and low power (below lookw) electric motors adopts a squirrel cage rotor. Copper bars are embedded in the rotor core slots, and the two ends of the copper bars are welded to the end rings. If the core is removed, the shape of the winding will resemble a squirrel cage
Definition and principle of electric motor
Electric motors and generators are devices that convert electrical energy and mechanical work. The equipment that uses electrical energy to perform mechanical work is called an electric motor, and the equipment that converts electrical energy into electrical energy is called a generator. Whether it is an electric motor or a generator depends on whether the current flows through a conductor in a magnetic field or moves in a magnetic field. The basic principle of electromagnetic force generation can be explained by Fleming's law of left and right.
