摘要

The electrical machine has winding heads, a water-cooled stator (11) and an air-cooled rotor (12). Air is passed through the rotor, the machine is provided to drive a vehicle and the stator is provided with cooling channels (18). The machine has a cooling sleeve (111) and the winding heads can have a setting material with structures for increasing its surface area.
