  • MOTOR MODULE, MOTOR CONTROLLER, TEMPERATURE INFERRING DEVICE, AND TEMPERATURE INFERENCE METHOD
    Publication number: 20190173413
    Abstract: A method to infer a temperature of windings in a stator of an electric motor includes repeating processing to infer electric resistance and temperature of the windings. The processing includes calculating a tentative electric resistance of the windings according to an equation that defines a relationship between electric resistance and a group of parameters; calculating a resistance difference between the tentative electric resistance and electric resistance inferred last time; detecting a change in a load state according to the parameters; inferring the electric resistance by adding the integrated value of calculated resistance differences to the initial value of the inferred electric resistance; and inferring the temperature of the windings according to the inferred electric resistance. In the inferring the electric resistance, a resistance difference calculated when a change in the load state is detected is excluded from the integrated value.
