Abstract
Various embodiments may include a rotor for an electric machine, the rotor comprising: a first shaft journal; a second shaft journal; a laminated rotor core; a filler body cast onto the laminated rotor core wherein the filler body and the laminated rotor core rotate conjointly; and a cooling duct extending through the shaft journals and the filler body along an axis of the filler body and the rotor core. The filler body rotates with the shaft journals and a torque applied to the shaft journals is transmitted to the laminated rotor core.
