What are the components of automobile starters?

Starter is composed of motor, driving mechanism and control mechanism. It is specially used to start the engine and needs strong torque, so the current to pass is very large, reaching several hundred amperes, which determines the difference between it and the generator. For example, with DC series motors, the rotor and stator are all wound with thick rectangular cross-section copper wires; The driving mechanism adopts a reduction gear structure; The operating mechanism adopts electromagnetic magnetic attraction.
