ABSTRACT:
An electrostatic shielding system is provided for an AC motor to eliminate generation of destructive motor bearing currents. Conductive end turn shields are layered over the stator coil end turns at each end of the stator. Conductive grounding clips mechanically and electrically engage the end turn shields at one end of the clip, and electrically and mechanically engage the slotted openings in the stator at the other end. Conductive strips extend longitudinally along the stator slotted openings.
