[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrodynamic rotating torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is the effect of the magnetic field on the force of the current, which makes the motor rotate. When the existing electric motor is in use, due to the input of internal current and continuous rotation, the heat inside the motor becomes higher and higher. For this reason, it is generally necessary to guide the heat inside the motor, and dissipate the heat inside the motor through the input and output of airflow.
