Electrical machine having a rotor for cooling the electrical machine

A vehicle, comprising an electrical machine mounted in or on the vehicle, the electrical machine including a stator, a rotor mounted for rotation about an axis of rotation and interacting magnetically with the stator during operation of the electrical machine, a shaft on which the rotor is fixed and which has an axial bore, and an inflow element sized to extend into the axial bore to enable a coolant to flow out of the inflow element and into the axial bore;

• a coolant circuit configured to transport the coolant through the axial bore;
• and a chamber disposed at an open end of the shaft, said chamber being delimited in an axial direction by an external axial boundary having one section extending transversely to the axis of rotation and disposed axially close to the shaft and another section also extending transversely to the axis of rotation but disposed axially distant from the shaft and enabling the coolant to be spirally guided around the axis of rotation into a coolant outlet.
