Rolling bearings in electric machines The purpose of using rolling bearings in electric machines is to support and locate the rotor, to keep the air gap small and consistent and to transfer loads from the shaft to the motor frame. The bearings should enable high and low speed oper-ations, min i mize friction, and save power. The designer has

In large motors, high frequency voltage is induced between the ends of the motor shaft by the high frequency flux circulating around the stator. This flux is caused by a net asymmetry of capacitive current leaking from the winding into the stator frame along the stator circumference. The voltage between the shaft ends affects the bearings.
