motor is one of the indispensable equipment in production and manufacturing. In order to ensure the normal operation of the motor, in addition to normal use according to operating procedures and normal monitoring and maintenance during operation, regular inspections and motor maintenance should also be carried out. . For the newly installed motor stator insulation resistance should be greater than 2MΩ, and the rotor insulation resistance should be greater than 0.8MΩ; for the motor in use, the stator insulation resistance should be greater than 0.5MΩ, and the rotor insulation resistance should be greater than 0.5MΩ; if it cannot reach a Standard, it should be removed and dried; in the drying condition (50~70), the stator insulation resistance reaches 1MΩ, and the rotor insulation resistance should be greater than 0.5MΩ.
1. The significance of daily motor maintenance:
A very important part of whether our mechanical equipment can work normally lies in whether the motor can operate normally. Therefore, motor maintenance is also very important. Many people always do not pay attention to maintenance or do not know how to maintain it. When there is a problem with the motor, the motor can only be repaired. Repairs will not only cost money, but also delay work. I regret not taking good care of it before. Maintenance is also a university question.
2. How to maintain the motor:
In normal times, pay attention to the maintenance of the motor: keep the motor clean and free of dust; check the appearance of the motor frequently to see if there are any misaligned parts; frequently check the bearings for replacement or oiling, and check the progress of the motor. Wire lugs.
If you want to maintain it carefully, daily maintenance is very important when the motor is running continuously: when the motor is working, pay attention to the working environment and do not be in a too bumpy state to prevent the motor from being damaged or reducing use. life. It is also necessary to conduct a visual inspection to see if the fan is working properly, whether there is abnormal vibration, whether the coupling connection is reliable, whether the base is fastened, whether the bearings are working normally (listen to the sound), and whether the temperature is normal ( infrared thermometer ), whether the current is normal (clamp ammeter), and the wound motor must also check the carbon brush and slip ring . If there is an abnormality in any aspect, you must repair the motor as soon as possible. Otherwise, you will not be able to handle the situation if it becomes serious.
3. The structure of the motor: The motor is composed of a stator frame, winding and insulating materials, a rotor, bearings at both ends and end covers.
