    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.

    摘要: Methods and apparatus are provided for improving operational characteristics of a concentrated winding machine. According to an example embodiment, an apparatus comprises stator teeth having distal ends, the stator teeth arranged in an annular fashion about an axis to define stator slots between adjacent teeth and slot openings between the distal ends of the adjacent teeth, the stator teeth structured to prevent relative movement between adjacent teeth. The apparatus further comprises magnetic wedges structured to be inserted between the distal ends of the adjacent teeth to close the slot openings.

    摘要: An internal permanent magnet machine (“IPM machine”) of the type used, for example, with traction motors and hybrid electric vehicles, includes a rotor with an additional air barrier provided above the first magnet barrier in the same rotor slot. Each magnet only fills a portion of each cavity, thereby defining the air barriers. The added air barrier above the permanent magnet of the first layer acts as a barrier to the first layer magnet and lowers the magnet flux.
