Application of Insulated Bearings in Electric motors

1. Causes and harm of motor shaft voltage and bearing current formation In the operation of the motor, any imbalance in the phase currents in or around the rotor’s magnetic circuit can  produce a rotating system flux linkage. When the shaft rotates, these flux chains can generate a potential difference across the shaft. This potential […]
