Lubrication of internal gear of electric motor

Wuxi Sine Power Technology Co., Ltd. tells you how to lubricate the internal gear of electric motor

Before opening the end cover of the electric motor, it should be clean as a garden to prevent sundries from being absorbed on the magnetic steel in the motor. Mark the comparison position between the end cap and the hub. Attention: it is necessary to loosen the screws diagonally to prevent the motor housing from deformation.

When the motor is disassembled and the motor fault is eliminated, the original end cover code must be used for equipment, so as to prevent the phenomenon of chamber sweeping after the secondary equipment.

Smoothness of internal gear of motor

If the noise of the operation of the brush gear hub motor and the brushless gear hub motor first increases and the gears in the motor are replaced, all the tooth surfaces of the gears should be coated with smooth grease, generally No. 3 smooth grease or the smooth oil specified by the manufacturer.

Assembly of motor

Before assembling the brush motor, please check the elasticity of the internal spring of the brush holder, whether the carbon brush and brush holder collide, whether the carbon brush can reach a very long distance in the brush holder, and pay attention to the correct positioning of the carbon brush and the phase changer to prevent the carbon brush or brush holder from being damaged.

Electric vehicle motor

When placing the motor, first of all, the impurities on the surface of the motor components should be cleared to prevent affecting the normal operation of the motor, and the hub body must be fixed and consolidated to prevent the components from colliding and damaging each other due to the attraction of the magnetic steel.

1. What is a motor?

The motor is a component that converts battery electric energy into machine energy and drives the wheels of electric vehicles to change.

2. What is a brush motor?

When the motor is working, the coil and commutator change, the magnetic steel and carbon brush do not rotate, and the alternating change of coil current direction is completed by the inverter and brush that roll with the motor. In the electric vehicle profession, the brush motor is divided into high-speed brush motor and low-speed brush motor. There are many differences between the brush motor and the brushless motor. From the name, it can be seen that the brush motor has carbon brushes, while the brushless motor has no carbon brushes.

3. What is a brushless motor?

The controller supplies DC in different current directions to achieve the alternating change of the coil current direction inside the motor. There is no brush and inverter between the rotor and stator of the brushless motor.

4. What are the common types of motors?

Common motors include: brush gear wheel motor, brush gear wheel motor, brush gear wheel motor, brush gear wheel motor, brush gear wheel motor, side hung motor, etc.
