The electrical energy provided by the battery is converted into mechanical energy, and the rotating torque is generated through electromagnetic action.

DC motor
The electrical energy provided by the battery is converted into mechanical energy, and the rotating torque is generated through electromagnetic action.
The interior includes armature (rotor), stator (field winding), commutator, brush and other components.
transmission mechanism
Also known as the starter clutch, it is responsible for transmitting the rotational force of the motor to the engine flywheel.
Common types include one-way clutches (such as roller type, friction type) to ensure that the starter is automatically disengaged after the engine is started, and to prevent the flywheel from damaging the starter.
Control device
It is mainly an electromagnetic switch, which controls the on and off of the starter circuit through electromagnetic force.
It includes attracting coil, holding coil, movable iron core and other components to realize the engagement and separation of the starter.
