What are the components of a starter?

[StEmiliano]

The starter is composed of three parts: the electric motor, the transmission mechanism, and the control device. It is specifically designed to start the engine and requires strong torque, thus drawing a large current, up to several hundred amperes. This characteristic distinguishes it from the generator. For example, it uses a DC series-wound motor, with both the rotor and stator wound with relatively thick rectangular cross-section copper wires; the drive mechanism employs a reduction gear structure; and the control mechanism uses an electromagnetic suction method. The motor used in the starter is a DC series-wound motor, whose function is to convert the electrical energy input from the lead-acid battery into mechanical energy, generating torque.
