Zusammenfassung:	In order to determine an operating temperature of an electric motor which is fed via an inverter, the inverter is first of all permanently assigned to an electric motor. Following calibration of measured value of at least one operating parameter of the electric motor by the assigned inverter on the production line of the electric motor and inverter, at least one measured value of at least one operating parameter of the electric motor is then acquired by the assigned inverter during operation of the electric motor and the operating temperature of the electric motor is determined using this at least one measured value and the calibration result from the assigned inverter.
