摘要： The invention relates to a method and a device for operating an externally excited electric machine (1), in particular synchronous machine. In this context, a variable which characterizes a rotor temeperature (Temp_Rotor) and/or a stator temperature is determined using a sensor system, and an exciter current (l_E) and stator currents (l_U, l_V, l_W) for the electric machine (1) are defined by a control unit (3) at least in predefinable operating ranges as a function of the variable which characterizes the rotor temperature (Temp_Rotor) and/or the stator temperature.
