The invention relates to a control device for an electric machine with a stator and a rotor, comprising a temperature detection device which is designed to detect the temperature of the stator and the temperature of the rotor, as well as a calculation device which is designed to adjust the operating point of said electric machine on the basis of a specified torque, the detected temperature of the stator, the detected temperature of the rotor, and a predefined thermal load distribution of said stator and rotor. The invention also relates to a vehicle and to a corresponding method for controlling an electric machine. 11234. A control device () for an electric machine () including a stator () and a rotor () , the control device comprising:{'b': 5', '6', '1', '3', '6', '2', '4, 'a temperature detection device () which is configured to detect the temperature (-) of the stator () and the temperature (-) of the rotor (); and'}{'b': 7', '8', '2', '9', '6', '1', '3', '6', '2', '4', '10', '3', '4, 'including a computing device () which is configured to set the operating point () of the electric machine () based on a torque specification () and the detected temperature (-) of the stator () and the detected temperature (-) of the rotor () and a predefined distribution () for the thermal load of the stator () and the rotor ().'}2. The control device as claimed in claim 1 ,{'b': 7', '8', '11', '13', '1', '13', '3', '12', '13', '1', '13', '3, 'wherein the computing device () is configured to set the operating point () by calculating a d-axis component () of a current vector (- to -) and a q-axis component () of the current vector (- to -) in a field-oriented coordinate system.'}3. The control device as claimed in claim 2 ,{'b': 14', '15', '2', '16', '17', '30', '2', '11', '12', '13', '1', '13', '3, 'including a memory () which is configured to store a machine-specific characteristic curve field () for the electric machine (), which specifies the resulting motor current () and the ...
