Beschreibung
Zusammenfassung:	An arrangement for determining a temperature of an electric machine includes a supply unit for operating the electric machine, with a first temperature of the electric machine computed with a first thermal model of the electric machine in the supply unit, and a computing facility connected to the supply unit by way of a data transmission channel, with a second temperature of the electric machine computed with a second thermal model of the electric machine in the computing facility. The supply unit and the computing facility communicate by way of the data transmission channel so as to enable the computing facility to determine the second temperature of the electric machine with the second thermal model even when no current is supplied to the supply unit.
