Bearing currents

In detail the three first-action solutions for bearing currents are: 1 - Incorporating an insulated bearing at the non-driven end An effective solution for motors with an IEC frame size of 280 and upwards is to substitute the bearing at the non-driven end with an insulated bearing that prevents current flowing through this point
