1. The armature core part: its function is to embed the armature winding and pass the magnetic flux to reduce the eddy current loss and hysteresis loss generated in the armature core when the motor is working.
2. Armature part: the function is to generate electromagnetic torque and induced electromotive force for energy conversion. dc motor controller ， The armature winding has many coils or glass coated flat steel copper wire or strength enameled wire.
3. The commutator is also called the commutator. In a DC motor, its function is to convert the current of the DC power supply on the brush into the AC current in the armature winding, so that the trend of the electromagnetic torque is stable. In the generator, it converts the AC electromotive force of the armature winding into the DC electromotive force output by the brush end.
