DC motor is a motor that converts DC electric energy into mechanical energy. The stator of the motor provides magnetic field, the DC power supply provides current to the winding of the rotor, and the commutator keeps the direction of the rotor current and the torque generated by the magnetic field unchanged. Its features are…
