ABSTRACT:
An apparatus reducing capacitive coupling between the stator and the rotor of an electromagnetic machine. The apparatus includes an electrically connective shield positionable between the stator and the rotor, the shield electrically separated from both the stator windings and the rotor when so positioned. A grounder electrically connects the shielder to ground thus substantially reducing capacitive coupling between the stator and the rotor.
