Abstract
A rotor, including a rotor core having teeth arranged star-shaped about a rotor axis, a winding per rotor tooth, which is wound around a corresponding tooth, and a displacement body arranged in a groove between the windings of adjacent teeth and extending in an axial direction. The rotor includes a cooling channel arranged in the displacement body, including a coolant inlet on an axial end face of the displacement body, configured to introduce coolant into the cooling channel, and a coolant outlet on an opposite axial front axis of the displacement body, configured to discharge coolant from the cooling channel. A slope is provided between the coolant inlet and outlet in a radial direction of the rotor. A distance in the radial direction from the coolant inlet to the rotor axis is less than a distance in the radial direction from the coolant outlet to the rotor axis.
