Abstract
A wedge for use in a generator rotor includes a wedge body having a generally triangular shape with flat surfaces, and such that when the wedge is placed in a generator rotor, the flat surfaces will define circumferential extents of the wedge body relative to a rotational axis of the rotor, and said flat surfaces extending to a radially outermost extent of the wedge body. A wedge and winding combination, a generator rotor, a generator and a method all using the wedges are disclosed and claimed.
