How to extend the life of your motor bearings | ABB

Jul 16, 2021· In the case of an electric motor, this path runs directly through the bearings. Since motor bearings utilize grease for lubriion, the oil in the grease forms a film that acts as a dielectric, which means it can transmit the electric forces without conduction. Over time though, this dielectric breaks down.

Oil leak causes and prevention in large electric motors

Jun 05, 2014· Abstract: Oil leaks are a common maintenance problem in large electric motors that can cause down time and even complete failure. The oil can migrate either to the inside of the machine or to the outside environment. This oil migration can be contributed to many factors, but one major cause is due to the differential pressure between the oil sump cavity and the …

Electric Motor Bearing Greasing and Lubriion

Most electric motors are designed with grease-lubried, antifriction, rolling-element bearings. Grease is the lifeblood of these bearings because it provides an oil film that prevents the harsh metal-to-metal contact between the rotating element and races. Bearing troubles account for 50 to 65 percent of all electric motor failures, and poor
