[0002] Before the automobile engine can run with its own power, it must rotate with the help of external force. The starter is a device that provides external force to start the engine. Existing starters generally consist of three parts: a DC motor, a transmission mechanism, and a control device. The DC motor includes an armature, and the structure of the armature generally includes a rotor shaft, an iron core assembly, a commutator, and a field winding.
