In order to ensure electrical work, in addition to normal use in accordance with procedures, normal operation of the process of monitoring and maintenance of attention, but also should carry out regular inspection, maintenance electrical work to do a good job. This can eliminate some problems in time to prevent the failure to ensure safe and reliable operation of motors. Regular maintenance intervals can be considered in accordance with the form of electrical use of environmental decisions.

Regular maintenance is as follows. 

1, the electrical brush clearance. Block timely removal of the electrical machine and external dust, sludge. More dust, such as the use of the environment, the best time every day cleaning. 

2, inspection and brush clearance motor terminals. Checking whether the junction box screws loose wiring, burn. 

3, inspection of the fixed part of screws, including screws and feet, cover screws, cap screws, such as bearings. Loosening of the nut will be tightened. 

4, gear check, check whether the drive pulley or coupling, damage, whether the installation of a solid; belt buckle is in good condition and its link. 

5, motor start-up equipment, but also external dust wipe clearance in time, you are, clean contact to check whether there are parts of the wiring burns is a good grounding line.

6, bearing the inspection and maintenance. In the use of bearings should be cleaned after a period of time, the replacement of grease or oil. Time cleaning and oil changes, should work with the motor, working environment, cleanliness, lubricant type, half of every 3-6 months, it should be washed once, re-grease for. High oil temperature, or poor environmental conditions, dust to be more frequent cleansing of the motor, the oil. 

7, insulation inspection. Insulating materials due to drying of the degree of insulation vary, so check the motor windings of the drying is very important. Motor humid working environment, workplace factors such as corrosive gases exist, would destroy the electrical insulation. The most common is the winding earth fault, or insulation damage, so that live parts with the chassis and other metal parts should not be charged encounter, the occurrence of such failure, not only affect the normal work of the electrical, but also endanger their personal safety. Therefore, the motor in use, should always check the insulation resistance, but also pay attention to check the reliability of the electrical chassis ground.

8, in addition to the above content by regular maintenance of the motor, the operation to repair a year later. The purpose of overhaul of the motor to conduct a thorough and comprehensive inspection, maintenance, and added to the lack of electrical wear of components, both within and outside the total elimination of the electrical dust, dirt, insulation inspection, the cleaning and inspection of the bearing wear. Identify problems to tackle them promptly. 

Generally speaking, as long as the correct, proper maintenance and found fault in time, the electrical work is a very long life.
