More Information
Summary:Disclosed in the embodiments of the invention are an electric motor winding and an electric motor stator. The electric motor winding includes: at least one first segmented coil group, wherein each first segmented coil group includes N first segmented coil units, any one of the first segmented coil units including M first hairpin coils with different slot pitches; any one of the first hairpin coils includes: a first slot outer end portion, a first slot inner portion, a first slot outer bending portion, a second slot inner portion and a second slot outer end portion which are connected sequentially, the first slot outer end portion and the second slot outer end portion extending oppositely in a circumferential direction; the M first hairpin coils are arranged concentrically; and the N first segmented coil units of the each first segmented coil group are arranged sequentially in the circumferential direction, and the parts in the N * M slots are distributed in two layers in a radial direction. The technical solution of the embodiments of the invention reduces the complexity of a manufacturing process, reduces the production cost, and improves the machining efficiency.
