Abstract

An electrical machine includes a stator and a rotor which is pivotally mounted about an axis of rotation and interacts magnetically with the stator during operation of the electrical machine. The rotor has a rotor cooling system for cooling the rotor using a first coolant flow, and the stator is cooled by a stator cooling system using a second coolant flow.
