Abstract:
1. A rotor, the rotor comprising: a first plurality of laminates each comprising a first keyway and a first tool access hole, and a first plurality of symmetric protrusions located at a periphery of each of the first plurality of laminates; a second plurality of laminates each comprising a second keyway and a second tool access hole, and a second plurality of symmetric protrusions located at a periphery of the second plurality of laminates, wherein the first keyways are initially angularly offset from the second keyways, and the first tool access holes are initially angularly offset from the second tool access holes; and a plurality of magnets, each magnet inserted between a channel formed between the first plurality of protrusions and the second plurality of protrusions, wherein reactive forces operate to hold the plurality of magnets, the reactive forces being caused by an angular offset of the first plurality of protrusions relative to the second plurality of protrusions based on a rotational deflection of at least one of the first plurality of laminates and the second plurality of laminates about a rotational axis, wherein each channel comprises a base having a convex form relative to a diameter of each laminate.
