It uses a energized coil (that is, a stator) to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotation torque. Since the rotor is constantly rotating during the working process of the motor, both ends of the rotor must be rotatably supported by bearing seats.

When the motor runs and the rotor rotates, the oil throwing ring rotates accordingly, and the oil throwing ring continuously The lubricating oil is thrown onto the bearing bush for lubricating and cooling. However, such motors have the problem that the temperature of the bearing pad and lubricating oil is too high (exceeding the safe operating temperature) during long-term operation, which may cause a burning pad accident and cause the bearing seat to be scrapped.
