Abstract
A stator assembly for a dynamoelectric machine in accordance with the present invention includes a generally cylindrically-shaped stator core having a plurality of core slots formed along the inner surface thereof and defined by a radial depth and wherein a stator coil is disposed. The plurality of core slots defines a plurality of teeth therebetween, which have caps along the inner surface of the stator core and are connected to the stator core by a yoke portion. The plurality of core slots is lined along respective inner surfaces by a plurality of insulation slot liners. The teeth caps include projections along an inner diameter of the plurality of core slots. The slot openings are delimited by the projections along the stator inner diameter. These projections are substantially equal to a width of the slot liners, and are such that the delimited slot openings are substantially equal to a width of a conductor wire to be inserted into the lined core slots. A stator winding includes slot wire segments that are received by the slot liners, which may be formed in at least one row of slot wire segments.
