The rotor part of the planetary gear stepper motors supplier is composed of armature core, armature, commutator and other devices. The following parts are introduced in detail.

1. Armature core part: Its role is to insert the armature winding and the flux at the end, in order to reduce the eddy current loss and hysteresis loss in the armature core when the motor is working.

2. Armature part: The role is to attack electromagnetic torque and induced electromotive force, and carry out energy transformation. The armature winding has many coils or glass-fiber-covered flat steel copper wire or strength enamelled wire.

3. Commutator, also known as commutator, in the planetary gear stepper motors supplier, its role is to convert the current of the DC power supply on the brush into the communication current in the armature winding, so that the electromagnetic torque tendency is stable and unchanged in the DC generator. It converts the communication electromotive force of the armature winding into the DC electromotive force of the output on the brush end.

The commutator consists of a cylinder composed of many pieces insulated with mica, and each end of the armature winding is separately connected to two commutator pieces. The role of the commutator in the DC generator is to convert the alternating electric heat in the armature winding into the direct current electromotive force between the brushes, there is current through the load, the DC generator outputs electric power to the load, and there is certainly current through the armature coil. It interacts with the magnetic field to attack the electromagnetic torque, which tends to be the opposite of the generator, the original idea is simply to suppress this magnetic field torque talented dynamic armature change. Therefore, the generator outputs electrical power to the load and outputs mechanical power from the original idea, completing the role of the DC generator in converting mechanical energy into electrical energy.
