Abstract

Tooth tips, which fit over teeth and distal ends of fingers formed between slots in laminated disks making up a portion of a stator in a generator, facilitate slipping stator windings into the slots from a central opening in the laminated disks; cooperate with wedges to affix stator windings in the slots; and provide a slot gap between adjacent tooth tips, which is substantially smaller than the width of the slots, to reduce slot harmonics and improve performance of the generator.
