ABSTRACT:
An electric machine, such as a motor or a generator, comprises a stator having a plurality of stator poles defining a plurality of slots, a rotor positioned within the stator, and at least a two sets of stator windings wound on the stator poles and occupying said stator slots such that the boundary windings of each set of stator windings occupies a common slot. These boundary windings of each set of stator windings are non-overlapping and include insulation positioned between them. The sets of stator windings are wound on the stator poles in a single pitch winding configuration significantly reducing the number of wire crossings resulting. In particular, the endturns defined by the individual phase coils are non-intersecting. Such a machine provides continued operation under various fault conditions.
