ABSTRACT
The article discusses the significance of shaft grounding as a cost effective approach to achieve sustainability of variable-frequency driver (VFD)-controlled motors. It explores the impact of VFDs on motor failure, especially the damages in the windings and bearings. It highlights the process of bearing insulation at one end for larger motors, and the process of insulating both bearings with high-impedance insulation for smaller motors.
