Can lubrication by our maintenance staff impact electric motor efficiency and reliability?
A. Yes, over lubrication and incompatible greases cause all kinds of problems. In a recent study, greasing a motor caused a decrease in motor efficiency by 1%. What can happen is that the added pressure may collapse the bearing shield or seal causing additional drag resulting in an efficiency and reliability loss. Many manufactures have recently changed grease types so reviewing current manufactures recommendations and lubrication compatibility might be a good idea.
