Shaded pole motor bearing repair method

Shaded pole motor bearings often use oil-containing bearings or rolling bearings. The oil-bearing bearings are sintered with copper-based or iron-based powder, which has a good self-lubricating effect. If the bearing is damaged, the vibration of the motor will increase, and a lot of abnormal noise will be emitted. In severe cases, the motor rotor will produce single suction or jamming, or even burn the main winding of the motor.

    Common failures of oil-bearing bearings are wear and dry lubricating oil. Check the inner hole size of oil bearing, if it is determined that the bearing is seriously worn, it should be replaced with a new bearing. If the bearing is not seriously worn and lacks lubricating oil, add lubricating oil or perform oil immersion treatment, soak the bearing in No. 10 engine oil, heat it to about 80～100℃, and cook it for several hours before use.
