DC motor is a rotating motor that can convert DC electric energy into mechanical energy (DC motor) or mechanical energy into DC electric energy (DC generator). It is a motor that can convert DC and mechanical energy into one another. When it runs as a motor, it is a direct current motor, which converts electrical energy into mechanical energy; when it runs as a generator, it is a direct current generator, which converts mechanical energy into electrical energy.

|The structure of DC motor should consist of two parts: stator and rotor. The static part of DC motor is called stator. The main function of stator is to generate magnetic field, which is composed of base, main magnetic pole, commutation pole, end cap, bearing and brush device. Running part is called rotor, whose main function is to generate electromagnetic torque and inductive electromotive force. It is the hub of energy conversion of DC motor. So it is also commonly called armature, which consists of rotor, armature core, armature winding, commutator and fan.

|DC CZPT is a machine that converts mechanical energy into DC CZPT . It is mainly used as DC motor for DC motor, electrolysis, electroplating, smelting, charging and excitation CZPT supply of alternator. Although in places where DC CZPT is needed, AC CZPT rectifier is also used to convert AC into DC CZPT , but from some aspects of performance, AC rectifier CZPT supply can not completely replace DC generator.
|DC motors are widely used in tape recorders, video recorders, video discs, electric shavers, hair dryers, electronic watches, toys and so on.

1. Use environment should be always dry, motor surface should be kept clean, air intake should not be hindered by dust, fibers and other obstacles.
2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or the overload or the setting value of the protective device is too low. After eliminating the fault, it can be put into operation.
3, ensure that the motor is well lubricated during operation. The general motor runs for about 5000 hours, that is to say, lubricating grease should be added or replaced. When bearing overheating or lubricating deterioration is found in operation, the hydraulic pressure should change lubricating grease in time. When replacing grease, the old grease should be removed, and the oil groove of bearing and bearing cover should be washed with gasoline. Then ZL-3 lithium grease should be filled with 1/2 (2 poles) and 2/3 (4 poles, 6 poles and 8 poles) of the cavity between the inner and outer rings of the bearing.
4. When the life of the bearing is over, the vibration and noise of the motor will increase obviously. When the radial clearance of the bearing reaches the following value, the bearing should be replaced.
5, when removing the motor, it is OK to remove the rotor from the shaft extension or the CZPT extension end. If it is not necessary to unload the fan, it is more convenient to take out the rotor from the CZPT -axle extension end. When pulling out the rotor from the stator, the stator winding or insulation should be prevented from being damaged.
6. When replacing the windings, the form, size, turns and gauges of the original windings must be recorded. When these data are lost, they should be obtained from the manufacturer and the original designed windings should be changed at will, which often deteriorates one or several performance of the motor or even makes it impossible to use them.
