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.
