Abstract
A method for checking a model temperature of an electrical machine ascertained by a temperature model. At least one manipulated variable relating to the electrical machine is specified by a regulation of the electrical machine as a function of a setpoint variable. A model value of the manipulated variable is ascertained as a function of the manipulated variable and the model temperature from a machine model comprising at least one temperature-dependent parameter. A difference between the actual manipulated variable of the regulation and the model value of the manipulated variable and/or a difference between a variable derived from the actual manipulated variable of the regulation and a corresponding further variable derived from the model value of the manipulated variable is ascertained. The difference is compared to a limiting value and, if the limiting value is exceeded, a deviation of the model temperature from an actual temperature of the electrical machine is detected.
