[0002] Before the automobile engine can run with its own power, it must rotate with the help of external force, mainly using the automobile starter. The automobile starter can convert the electrical energy of the battery into mechanical energy, drive the engine flywheel to rotate and start the engine. The automobile starter includes necessary armatures, commutators, magnetic poles, brushes, keyway bearings, housings and rear end covers.
