Abstract
A dynamoelectric-machine stator includes a stator lamination stack, a plurality of electrically-conductive magnetic wedges, a plurality of electrically-insulative nonmagnetic wedges, and coil windings. The stator lamination stack has circumferentially-spaced-apart stator teeth. Adjacent stator teeth each have a tooth side bounding an intervening stator slot. Adjacent stator teeth each have a radially-outermost tooth tip which circumferentially projects from the corresponding tooth side into the intervening stator slot to partially close the intervening stator slot. The coil windings are randomly wound in the stator slots. The magnetic wedges are each positioned in a corresponding stator slot and physically and solid-magnetically contact the corresponding tooth tips to fully close the corresponding stator slot proximate the corresponding tooth tips. The nonmagnetic wedges are each positioned in a corresponding stator slot between the corresponding coil windings and the corresponding magnetic wedge. A stator-slot magnetic wedge of particular shape is also described.
