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.
