DC motor introduction
A DC motor is a rotating electrical machine that converts DC electrical energy into mechanical energy (DC motor) or converts mechanical energy into DC electrical energy (DC generator). It is a motor that can convert DC power and mechanical energy. When it is used as a motor, it is a DC motor that converts electrical energy into mechanical energy. When the generator is running, it is a DC generator that converts mechanical energy into electrical energy. The working principle of the DC generator is to change the alternating electromotive force induced in the armature coil by the commutation function of the commutator and the brush to change the DC electromotive force when it is taken out from the brush end.

The working principle of the DC generator is to change the alternating electromotive force induced in the armature coil by the commutation function of the commutator and the brush to change the DC electromotive force when it is taken out from the brush end.
The structure of the DC motor should consist of two parts: the stator and the rotor. The part of the DC motor that is stationary during operation is called the stator. The main function of the stator is to generate a magnetic field. It consists of a base, a main pole, a commutating pole, an end cover, a bearing and a brush device. The part that rotates during operation is called the rotor. Its main function is to generate electromagnetic torque and induced electromotive force. It is the pivot of energy conversion of DC motor, so it is usually called armature. It is changed by shaft, armature core, armature winding, and It consists of a transmitter and a fan.
