Abstract: A motor for use in a refrigerant atmosphere includes a rotor configured to rotate about an axis and a stator adjacent the rotor. The stator includes a core defining an end, and a plurality of teeth defining a plurality of slots. A plurality of coils are wrapped around the plurality of teeth such that each coil of the plurality of coils comprises a pair of slot portions extending at least partially through adjacent slots of the plurality of slots and an end turn extending between the slot portions and at least partially across the end. A shell encapsulates the end of the stator such that the end turns of said plurality of coils are substantially sealed from the refrigerant atmosphere.

Abstract: A motor for use within a refrigerant atmosphere includes a plurality of laminations stacked along an axis, the laminations cooperating to define a plurality of teeth and a slot disposed between each pair of adjacent teeth, a plurality of coils each positioned around a tooth such that each coil is partially disposed in two adjacent slots, and a first phase winding formed from at least two coils, the first phase winding including a single continuous conductor. An insulating member is disposed within each of the slots and arranged to electrically insulate the coil within the respective slot from the laminations and a wedge is positioned within at least one of the slots. The wedge is operable to compress the coil within the slot. A rotor is positioned adjacent the stator and is operable to rotate about the axis.
