It is primarily composed of electrical components that convert electrical energy into mechanical energy, including rotors, stator windings, housings, and speed sensors. The main function of a micromotor housing is to prevent the human body from touching or approaching live parts and rotating parts inside the housing, while preventing solid foreign matter from entering the motor. It also has dust and water-proof properties, preventing harmful effects caused by water entering the motor. With the development of society, micromotor housings are used when motor components need to be protected.
