摘要： A rotor assembly is assembled by providing an elongated rectangular strip of material having a first edge and a second edge defining a width, cutting the elongated rectangular strip to form a first patterned strip having a first side corresponding to the first edge, winding the first patterned strip portion around the perimeter of the rotor core such that the first edge is adjacent to the perimeter and the patterned strip portion forms a continuous laminated ring structure. Two laminated ring structures can be cut from a single strip, thereby reducing waste material and forming a strong structure.

摘要： In general, the various embodiments are directed to a permanent magnet machine (“PM machine”), and more specifically an internal permanent magnet machine (“IPM machine”) that includes rotor magnets configured asymmetrically with respect to the rotor periphery, thereby producing an averaging effect similar to that achieved through traditional skewing of the rotor magnets. In alternate embodiments, the span, placement and/or shape of the magnets may vary from one pole to the next.

摘要： Systems and methods are provided for a motor having a concentrated winding construction with reduced torque ripple. A motor comprises a stator including a plurality of tooth segments disposed circumferentially to establish a hollow core and a rotor rotatably disposed inside the hollow core. The plurality of tooth segments define a plurality of slot openings associated with a plurality of slots. Each slot of the plurality of slots has a slot opening and at least one slot opening of the plurality of slot openings is asymmetric with respect to the plurality of slot openings.
