[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. Motors can be divided into DC motors and AC motors according to the type of working power supply; they can be divided into DC motors, asynchronous motors, and synchronous motors according to the structure and working principle; they can be divided into capacitor-start single-phase asynchronous motors, capacitor-operated single-phase asynchronous motors, capacitor-start-operated single-phase asynchronous motors, and split-phase single-phase asynchronous motors according to the starting and running mode; they can be divided into drive motors and control motors according to their use.

A heat dissipation fan 9 is installed in the sleeve 7 through a fixing frame 8. The device has a simple structure and is easy to use. The heat dissipation mechanism can provide good heat dissipation capacity when a high-power motor is running, thereby avoiding heat accumulation inside the motor to affect the operating efficiency of the motor and ensuring the normal operation of the motor.
