A rotor for an electromagnetic apparatus including: ferromagnetic laminates stacked along a longitudinal axis of the rotor; non-magnetic laminates stacked along the longitudinal axis, wherein the non-magnetic laminates are between the ferromagnetic annular laminates; cavities in the rotor formed by aligned slots in the ferromagnetic and non-magnetic laminates, wherein the cavities are parallel to the axis of the rotor, and a permanent magnet(s) in each of the aligned cavities. The laminates may each be an annular disc or may be segments arranged in an annular array around a shaft of the rotor.

Permanent magnet rotor having a combined laminated stack and method of assembly

A system including an electromagnetic braking system that has an eddy current brake. The eddy current brake includes an electrically conductive surface coupled to a shaft of a generator system, wherein the eddy current brake is configured to induce an electromagnetic force on the electrically conductive surface when powered. The electromagnetic braking system further includes a supercapacitor coupled to the eddy current brake, wherein the supercapacitor is configured to discharge to power the eddy current brake for the duration of a ride through event of the generator system, and the supercapacitor is configured to supply a threshold current to the eddy current brake within approximately 100 ms of a start of the ride through event.

System and method for generator braking

A laminated rotor and an electric machine including the laminated rotor are disclosed. In an embodiment, a rotor comprises a plurality of stacked laminations, wherein each lamination includes a plurality of radially extending slots arranged about a circumference of each of the plurality of laminations, and the plurality of radially extending slots in successive laminations in the stack are aligned. A stud member passes longitudinally through at least one hole in the lamination stack, and a plurality of coils are positioned within the plurality of slots. Fewer than all of the plurality of slots have a coil positioned therein, leaving at least three slots empty. Balance members may be placed in the slots that do not have a coil positioned therein to balance the rotor.

Laminated rotor balancing provisions

A pole assembly for a rotor, the pole assembly includes a permanent magnet pole including at least one permanent magnet block, a plurality of laminations including a pole cap mechanically coupled to the pole, and a plurality of laminations including a base plate mechanically coupled to the pole.
