Abstract:
1. An apparatus, comprising: a first winding portion from a plurality of winding portions, the first winding portion having a plurality of coils, each coil from the plurality of coils of the first winding portion being associated with a different electrical phase from a plurality of electrical phases, each coil from the plurality of coils of the first winding portion circumscribing a different area from a plurality of areas circumscribed by the plurality of coils on the first winding portion, at least a portion of each coil from the plurality of coils of the first winding portion collectively defining a first layer, the first winding portion configured to at least partially overlap a second winding portion (1) from the plurality of winding portions and (2) having a plurality of coils associated with the plurality of electrical phases, the first winding portion configured to at least partially overlap a third winding portion (1) from the plurality of winding portions and (2) having a plurality of coils associated with the plurality of electrical phases, at least a portion of each coil from the plurality of coils of the second winding portion and at least a portion of each coil from the plurality of coils of the third winding portion collectively defining a second layer substantially parallel to the first layer, the first winding portion configured to at least partially overlap the second winding portion and the third winding portion such that an area on the second layer and between a portion of a coil, (1) from the plurality of coils of the second winding portion and (2) associated with an electrical phase from the plurality of electrical phases, and a portion of a coil, (1) from the plurality of coils of the third winding portion and (2) associated with the electrical phase, is substantially circumscribed by a coil (1) from the plurality of coils of the first winding portion and (2) associated with the electrical phase.
