<p>A stator core extends along a longitudinal axis and includes a yoke, and a plurality of radially-inwardly projecting teeth separated by intervening slots. A radially innermost portion of each tooth initially includes a pair of legs separated by a recess disposed therebetween. The conventional tooth tips are unformed in the first stage, thereby defining an increased-size slot opening for allowing the insertion of an enlarged stator winding, which has a width (e.g., diameter for a round conductor) substantially equal to the width of the slot itself. In a second processing stage, after the core itself has been manufactured and wound with stator windings, the legs are cold-formed in order to form tooth tips, which define a reduced-size slot opening to provide an improved magnetic flux path and provide a wire retention function. A high slot fill stator design is provided, which allows and enables higher generator efficiencies and output for a given package size. <IMAGE></p> |
