A method and a device for operating an electrical machine having separate excitation, especially a synchronous machine. With the aid of a sensor system, a variable characterizing a rotor temperature and/or a stator temperature are/is determined, and an excitation current and stator currents for the electrical machine are specified by a control unit as a function of the variable characterizing the rotor temperature and/or the stator temperature, at least in specifiable operating ranges.

1. A method for operating an electrical machine having separate excitation, the method comprising: determining a variable that characterizes a stator temperature; andshifting a current distribution between an excitation current and stator currents for the electrical machine at least in specifiable operating ranges, as a function of the variable characterizing the stator temperature,wherein in a first operating range, in which the stator temperature lie(s) below a specifiable first limit value, the excitation current and the stator currents for a specified working point of the electrical machine, which is defined by a torque and an engine speed, are specified in efficiency-optimized manner independently of the stator temperature. 2. The method of claim 1, wherein at least three operating ranges are formed as a function of the variable characterizing at least one of a rotor temperature and the stator temperature. 3. The method of claim 2, wherein in a second operating range, in which the at least one of the rotor temperature and the stator temperature lie(s) above the first limit value but below a predefinable second limit value, the excitation current and the stator currents of the electrical machine are specified as a function of the variable characterizing the at least one of the rotor temperature and the stator temperature, without reducing a maximally allowed power of the electrical machine in the process. 4. The method of claim 2, wherein in a third operating range, in which the at least one of the rotor temperature and the stator temperature lie(s) above the second limit value, the maximally permitted power of the electrical machine is reduced. 5. The method of claim 4, wherein the excitation current and the stator currents in the third operating range may be specified in efficiency-optimized manner independently of the variable characterizing the at least one of the rotor temperature and the stator temperature. 6. The method of claim 4, wherein the excitation current and the stator currents in the third operating range are specified as a function of the variable characterizing the at least one of the rotor temperature and the stator temperature. 7. The method of claim 1, wherein the electrical machine is used as drive unit for a vehicle, and the excitation current and the stator currents for the electrical machine in the specifiable operating ranges are specified as a function of additional operating parameters of the vehicle. 8. The method of claim 1, wherein the electrical machine serves as drive unit of a vehicle, and at least one of the first limit value and the second limit value is specified as a function of additional operating parameters of the vehicle. 9. The method of claim 1, wherein the electrical machine is a synchronous machine. 10. The method of claim 1, wherein a variable that characterizes a rotor temperature is also determined, and wherein the current distribution between the excitation current and stator currents for the electrical machine is shifted, at least in specifiable operating ranges, as a function of the variable characterizing the rotor temperature. 11. A device for operating an electrical machine having separate excitation, comprising: a sensor system for detecting a variable characterizing a stator temperature; anda control unit, which shifts a current distribution between an excitation current and stator currents for the electrical machine as a function of the variable characterizing the stator temperature, at least in specifiable operating ranges,wherein in a first operating range, in which the stator temperature lie(s) below a specifiable first limit value, the excitation current and the stator currents for a specified working point of the electrical machine, which is defined by a torque and an engine speed, are specified in efficiency-optimized manner independently of the stator temperature. 12. The device of claim 11, wherein the electrical machine is a synchronous machine. 13. The device of claim 11, wherein the sensor system also detects a variable characterizing the rotor temperature, and wherein the control unit shifts the current distribution between the excitation current and stator currents for the electrical machine as a function of the variable characterizing the rotor temperature, at least in specifiable operating ranges.
