1. A method for the thermal treatment of a compressed strand of an electric motor of an electric vehicle, wherein the thermal treatment of the compressed strand is carried out after the electrical motor is assembled within the vehicle,
wherein heating said compressed strand for thermal treatment is carried out by applying electric current to said compressed strand,
wherein the thermal treatment on said compressed strand is completed after or during an initial operation of the vehicle once put in service, and said compressed strand is heated by regulating or switching off the motor cooling and/or by idling load, as a result of intentionally applied leakage currents which generate heat but no torque.
