    Abstract: An electrical machine having a machine output rating. The electrical machine including a shaft rotatable about an electrical machine axis, a rotor coupled to the shaft and rotating with the shaft, and a stator including a stator core. The rotor is configurable to include a first rotor portion having a relation to a first output rating and a second rotor portion having a relation to a second output rating. The stator core is configurable to be disposed adjacent to the first rotor portion relative to the machine axis when the machine output rating corresponds to the first output rating and adjacent to the second rotor portion when the machine output rating corresponds to the second output rating.

    Abstract: A rotor for an electric machine having a number of poles includes a shaft that extends along a portion of an axis and defines an outer surface. A first core portion extends along a portion of the axis to define a first core length. The first core portion includes a first reduced back portion that has an inside surface that does not contact the outer surface. A second core portion is coupled to the first core portion for rotation. In some constructions, a coupling member interconnects the shaft, the first core portion, and the second core portion such that the shaft, the first core portion, and the second core portion rotate about the axis substantially in unison.

    Abstract: An electrical machine comprises a stator and a rotor. The rotor includes a plurality of stator teeth and a winding with compact coils disposed on the teeth. The winding has (m) phases and (p) poles; where (m) is an integer and is greater than or equal to two; where (p) is an integer, is greater than or equal to two, and is an even number. The rotor has a magnetization pattern including a magnetization skew. In some constructions, each stator includes one or more channels along a surface adjacent to the rotor. The channels can be of various shapes including a trapezoidal shape or a curvilinear shape.
