摘要： An assembly for an electric motor includes a stator including a plurality of stator poles, each stator pole including a base end and a rotor end opposite the base end, and an electromagnetic coil around each stator pole. The coil around each stator pole includes at least two electrically conductive wires wound into multiple wire turns around the stator pole that extend from the base end of the stator pole to the rotor end of the stator pole. Wire turns of the coil closer to the rotor end of the stator pole are twisted and wire turns of the coil closer to the base end of the stator pole are not twisted.
