ABSTRACT:
An electric machine having multi-set rectangular copper hairpin windings comprises a stator having a plurality of partially closed stator slots. A first winding set and a second winding set are positioned in the stator slots. The first winding set and the second winding set are connected by adjacent leg ends. According to a first embodiment, conductor layers in alternate slots alternate between different phases. The conductor layers in the remaining slots are all of the same phase. Hairpins having unequal length legs are used to implement the first embodiment. According to a second embodiment, conductor layers in alternate slots include one phase for the first winding set and another phase for the second winding set. The conductor layers in the remaining slots are all of the same phase. Hairpins having equal length legs are used to implement the second embodiment.
