What is the composition of the rotor of dc gearmotor

The basic structure of dc gearmotor is divided into two parts: stator and rotor. The stator includes the main magnet, base, commutation and brush device. The rotor includes armature core, armature (shu) winding, commutator, shaft and fan. Today we come to understand what are the components of the rotor.
The rotor part of dc gearmotor is composed of armature core, armature, commutator and other devices. The following is a detailed introduction of each component in the structure.

1. Armature core components: function to embed the armature winding and the magnetic flux on the tip to reduce the eddy current loss and hysteresis loss in the armature core during the operation of the dc gearmotor.
2. Armature part: The function produces electromagnetic torque and induced electromotive force, and performs energy conversion. The armature winding has many coils or glass fiber coated flat steel copper wire or strength enameled wire.
3. The commutator is also called the commutator. In the dc gearmotor, its role is to convert the current on the brushes of the DC power supply into the AC current in the armature winding, so that the electromagnetic torque trend is stable. In the DC generator motor, it converts the AC electromotive force of the armature winding into the DC electromotive force output at the brush end.
The commutator consists of mica insulation between the cylinders composed of many pieces, and both ends of each coil of the armature winding are connected to two commutator pieces. The role of the commutator in the dc gearmotor motor converts the alternating electromotive force in the armature winding into the direct current electromotive force between the brushes, and the current passes through the load.
The dc gearmotor outputs power to the load, and the current must pass through the armature coil. It uses the electromagnetic torque generated by the magnetic field, and its trend is opposite.
