Abstract
A rotor with wedges and a method of retaining wedges in a rotor are disclosed. The rotor includes a shaft, first and second poles extending radially from the shaft, and first and second coils of windings respectively wrapped around the first and second poles. Each coil includes a respective outer face including two end portions and two side portions, and a respective inward-facing edge including two end sections and two side sections. The rotor further includes a first outer wedge positioned between neighboring side portions of the first and second coils, and a first inner wedge positioned between neighboring side sections of the first and second coils. The first inner wedge is coupled to the first outer wedge so that the first outer wedge is at least partly retained from moving radially outward away from the shaft.
