Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame.

Bearing failures are the most common cause of electric motor and generator failure. Maintenance professionals can optimize the life of these machines by following industry best practices for bearing ...

When it comes to assuring that a motor provides consistent service for the longest time possible, it’s important to pay attention to the bearing system. Bearing system failures are one of the most ...

Reliability and maintenance engineers are often given the task of improving the reliability of bearing arrangements in a variety of applications. Lubrication is a key area to explore for improvement ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...
