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.
Claims4
An armature winding for a stator of an electrical generator, the stator having a circumferential periphery, comprising:
- (a) a first winding segment extended inside the circumferential periphery of the stator;
- (b) a second winding segment extended inside the circumferential periphery of the stator;
- (b) a third winding segment extended outside the circumferential periphery of the stator and interconnecting the first and second winding segments;
- and
- (c) an electrical short near the circumferential periphery of the stator between the winding segments to prevent current from flowing through the third winding segment.
