A liquid-cooled rotor for an electromechanical energy converter has a rotor shaft designed, at least in portions, as a hollow shaft and having a first, open axial end, a liquid-guiding device extending through the first end into the rotor shaft, wherein an annular liquid space is between the liquid-guiding device and the rotor shaft in the radial direction, and the liquid-guiding device has an interior space for guiding liquid and a liquid inlet opening into the interior space and arranged at a first axial end of the liquid-guiding device, the liquid-guiding device, at a second axial end, is received in the rotor shaft and guiding relative to the rotor shaft, and has a liquid outlet opening fluidically connecting the interior space to the annular liquid space, and the liquid outlet opening is between the first and second ends of the liquid-guiding device in the axial direction.

Liquid-cooled rotor for an electromechanical energy converter

The invention relates to an electrical machine, such as a motor vehicle that includes a rotor connected to a hollow shaft mounted such that it can rotate about an axis of rotation. The electric machine also includes a rotary transformer that includes a first slip ring and a first brush adjacent thereto. The first slip ring may be arranged inside the hollow shaft and is connected thereto. The invention also relates to a motor vehicle that includes a drive wheel that is operatively connected to the electrical machine.
