Summary:An electromagnetic apparatus produces an asymmetrical magnetic field. The electromagnetic apparatus includes a stator and a rotor rotatable relative to the stator. The stator includes electrically conductive wiring subject to non-zero voltage input. The rotor includes an electrically conductive rotor shaft having a shaft voltage induced therein. The electromagnetic apparatus further includes a bearing rotatably supporting the rotor shaft and an electrically insulative arcing shield disposed in overlying engagement with the bearing. The arcing shield comprises a fibrous composite material. The fibrous composite material includes a plurality of fibers and a resin.
