Abstract
The present disclosure relates to cooling devices. The teachings thereof may be embodied in devices for cooling a rotor, which rotates about an axis, wherein the rotor is supported by a central rotor shaft. For example, in a cooling device, the rotor may be supported by a central rotor shaft and comprise a hollow space in the interior of the rotor shaft for accommodating coolant. It may include a first coolant line extending radially outwardly from the hollow space and an annular first distribution line fluidically connected to the hollow space via the first coolant line.
