摘要： A rotor (100) having a first plurality of laminates (110), comprising a first plurality of protrusions (120) located at a periphery of each of the first plurality of laminates, and a second plurality of laminates (1101), arranged differently from the first plurality of laminates (110) around a shaft hole (132), comprising a second plurality of protrusions (120′) located at a periphery of each of the second plurality of laminates, wherein the first plurality of protrusions are asymmetric and/or angularly offset from the second plurality of protrusions, and wherein the second plurality of protrusions are asymmetric and/or angularly offset from the first plurality of protrusions. The rotor further having a plurality of magnets (115), each inserted between the first plurality of protrusions and/or the second plurality of protrusions, wherein reactive forces operate to hold the plurality of magnets.
