ABSTRACT:
A segmented stator for a permanent magnet motor. The stator includes a plurality of stator segments forming an annular stator yoke and a plurality of stator teeth extending from an edge of the stator yoke. At least one coupling is between adjacent stator segments and shaped to allow movement of adjacent teeth in a so-called loose tooth design. Slot wedges are located between adjacent teeth to prevent the conductive windings from moving out of the slots through the slot openings. The slot wedges also prevent movement of adjacent teeth with respect to one another. The segmented stator can comprise an annular yoke with a plurality of discrete teeth or a plurality of assemblies including a rim section and a tooth section. The slot wedges can be keyed wedges that maintain their position through interlocking and/or can be integrated with a stator bobbin.
