  • Pigtailed stator windings for electrical generator
    Patent number: 7687960
    Abstract: A modified armature winding for a stator of an electrical generator having a pigtail shape to promote cooling of the stator. At least one turn of the windings is extended outside the circumferential periphery of the stator, preferably forming a loop. An electrical short is created near the circumferential periphery of the stator between the winding segments to prevent current from flowing through the pigtail winding segment.
