We all know that dc motor and generator work on the principle that the structure of dc motor should be composed of stator and rotor.The stationary part of the DC motor is called the stator. The main function of the stator is to generate a magnetic field, which is composed of the frame, main magnetic pole, commutator pole, end cover, bearing and brush device.The rotating part of the rotor, whose main role is to generate electromagnetic torque and induction electromotive force, is the hub of energy conversion for DC motor, so it is usually called the armature, by the shaft, armature core, armature winding, commutator and fan, etc.
So when we customize the motor we also need to know what are the categories?
According to the results, dc motor and DC generator can be divided into brushless DC motor and brushless DC motor.The excitation mode of dc motor is the problem of how to supply the excitation winding and generate the excitation flux potential to establish the main magnetic field.
A dc generator is a machine that converts mechanical energy into direct current energy.It is mainly used as dc motor, electrolysis, electroplating, electrosmelting, charging and ac generator excitation power.Although direct current is needed in the place, also USES the power rectification element, converts the alternating current to the direct current, but looks from the certain performance aspect, the alternating current rectification power source still cannot replace the direct current generator completely.
