Abstract:
A wedge for securing windings in a slot in the rotor poles of a rotor core of an electrical machine includes an elongate wedge body extending in an axial direction along a longitudinal axis. The wedge body includes layers perpendicular to the axial direction. The layers vary in electrical conductivity from layer to layer to inhibit eddy currents within the wedge body.
