Abstract:
A wedge for use in an electric machine has a central leg and arms extending in both circumferential directions. The wedge has a radially outer full surface defining a cylindrical aperture through an axial length, and ledge surfaces at each axial end of the full surface. A curved merging portion on an outer surface of the arms merges into a curved contact surface. A rotor, a machine and a method are also disclosed.
