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 ...

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.

Electric motors fitted with variable frequency drives are at risk of bearing damage due to a build-up of current in the rotor that discharges through the shaft, damaging the lubrication and bearing ...

High efficiency motors can bring significant savings but if budgets won’t stretch to motor replacement, energy efficient bearings offer a powerful cost-saving alternative. Up to 80% of all electric ...

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 ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...

The experts at eMotors Direct outline how VFD’s can damage bearings and discuss preventative measures to prevent VFD induced bearing damage Electric motors fitted with VFDs (Variable Frequency Drives) ...
