Abstract
A rotor and a method of constructing a rotor are disclosed. The rotor includes a hub that is capable of being supported by a shaft that extends along an axis, a plurality of laminations, and a plurality of wire windings supported by the plurality of laminations. The hub includes an inner structure configured to support the hub relative to the shaft, an outer structure that supports the laminations, and an intermediate structure that is coupled to the inner and outer structures and supports the inner and outer structures relative to one another.
Claims3
A method of constructing a rotor, the method comprising:
- providing a hub having an outer structure with a cylindrical support surface and a retaining ring, an inner structure forming a cylindrical cavity, and an intermediate structure coupled to the inner and outer structures and configured to support the inner and outer structures relative to one another;
- positioning a plurality of ring-type laminations and a pair of insulating rings onto the cylindrical support surface, wherein a first of the pair of insulating rings is positioned on a first side of the plurality of laminations and a second of the pair of insulating rings is positioned on a second side of the plurality of laminations, wherein the laminations and insulating rings are positioned so that the first of the pair of insulating rings abuts the retaining ring;
- shrink-fitting the ring-type laminations and insulating rings onto the cylindrical support surface;
- positioning a balancing ring onto the cylindrical supports surface so that the balancing ring abuts the second of the pair of insulating rings;
- shrink-fitting the balancing ring onto the cylindrical support surface;
- and
- wrapping a plurality of wire windings onto the laminations.
