6. Bearing inspection and maintenance. Bearings should be cleaned after a period of use, and grease or lubricating oil should be replaced. The time of cleaning and oil change should be determined by the working conditions of the motor, the working environment, the degree of cleanliness, and the type of lubricant. Generally, every 3-6 months of work should be cleaned and the grease should be changed again. When the oil temperature is high, or the motor with poor environmental conditions and more dust should be cleaned and changed frequently.

The motor working environment is humid, the working room has corrosive gas and other factors, will destroy the electrical insulation. The most common is the winding grounding fault, that is, insulation damage, so that the live part and the casing should not be charged metal parts of the collision, the occurrence of this fault, not only affect the normal operation of the motor, but also endanger personal safety. Therefore, the motor in use, should always check the insulation resistance, but also pay attention to check the motor shell grounding is reliable.

The purpose of overhaul is to carry out a thorough and comprehensive inspection and maintenance of the motor, supplement the missing and worn components of the motor, completely eliminate the dust and dirt inside and outside the motor, check the insulation, clean the bearings and check their wear.
