Electrically insulated bearings from QIBR

Electrically insulated bearings from QIBR The problem of stray electric current bearing damage When a stray current in an electric motor uses a bearing as its path to ground bearing damage can occur The most common causes of stray electric currents are: asymmetry

The purpose of insulated bearing for Motors with VFD

Dec 09 2015The best method for mitigating bearing currents is to use hybrid bearings in both ends of the motor as insulated bearings (in both ends) is often not enough to withstand the capacitive bearing currents introduced by a VFD Insulated bearings are unfortunately often very costly compared to a rather similar performance using common mode chokes
