The essence! 7 tips to extend the life of three-phase asynchronous motors with Dalan Motor

Although the three-phase asynchronous motor is protected by a hard shell, its interior is extremely fragile. Specifically, how do we take care of it, Dalan Motor Editor will share 7 tips for you today.

The main inspection and maintenance items of the motor are as follows:

1. Remove the dust and oil sludge outside the motor base in time. If there is a lot of dust in the environment, clean it once a day.

2. Frequently check the terminal board screws for looseness or burns.

3. Periodically measure the insulation resistance of the motor. If the environment is humid, it should be measured frequently.

4. Regularly clean the bearings and replace with new oil (generally changed every six months), should not be full when changing oil, generally occupy 1/2 to 1/3 of the oil cavity, otherwise, it is easy to heat or throw out, the oil should be added from one side People can squeeze out impurities that have not been cleaned from the other side.

5. Regularly check the starting equipment to see if the contacts and wiring are burned, oxidized, and whether the contact is good.

6. Check the insulation. The insulating capacity of the insulating material varies with the degree of drying, so it is very important to keep the motor windings dry. Therefore, when the motor is in use, the insulation resistance should be checked frequently, and pay attention to see whether the motor chassis grounding is reliable.

7. In addition to the maintenance of the motor according to the above items, it needs to be overhauled once after the motor runs for one year. Its purpose is to conduct a thorough and comprehensive inspection and maintenance of the motor, supplement the missing and worn components of the motor, completely remove the dust and dirt inside and outside the motor, check the insulation, clean the bearings and check their wear.

After being processed in the above way, it can not only effectively extend the life of the motor, but also have a positive effect on safe production.
