Cause and treatment method of grounding of DC motor pole winding

1 transmission gear mesh is not good, the motor produces high frequency impact vibration, the coil is subjected to a lot of power. Remove the motor repair, should ensure that the original gear meshing. Replacement must be grouped together for.

2 insulation aging, need to replace the insulation.

There are 3 water, oil, powder invasion, insulation performance degradation. Need to improve the structure, reduce the water pollution intrusion; improve the quality of the paint and cover the paint; improve the resistance to the ground insulation resistance, pollution resistance and electrical strength; regular maintenance clean-up.

4 motor terminal voltage is too high, should adjust the voltage.
