The working principle of the starter motor: A DC motor is a device that converts electrical energy into mechanical energy. It is based on the principle that a charged conductor is subjected to electromagnetic force in a magnetic field. Because the torque generated by one coil is too small and the rotational speed is unstable, in fact, there are many coils wound around the armature of the motor, and the number of commutation segments increases correspondingly with the increase of coils. So as to ensure the generation of sufficient torque and stable speed.
