Abstract:
1. A multi phase generator armature winding, comprising: an asymmetrical armature coil winding for each pole with the associated phase organized into at least first and second three-phase winding groups, each winding group producing a symmetrical electrical output, each winding group being asymmetrically wound within slots in the armature with relation to remaining winding group(s); the winding groups including clockwise-wound (CW-wound) coil groups and counterclockwise-wound (CCW-wound) coil groups; the CCW coil groups including a set of two CCW-wound coils with a clockwise series connection between the two CCW-wound coils of each set, wherein the set of two CCW-wound coils include a first CCW-wound coil having a first span that overlaps a second span of a second CCW-wound coil; and the phases of each three-phase winding group having an equal relative phase shift therebetween, wherein a number of the windings that use a same slot varies between slots, wherein within a plurality of phases in the winding groups, windings are asymmetrical to each other.
