More Information
Summary:A motor control apparatus that estimates a temperature of a temperature estimation target element at a time of energizing the motor and drives a motor by controlling an electric power is provided. The motor control apparatus includes a primary delay arithmetic unit that outputs a primary delay response as an amount of temperature change, a sensor value adder that adds a sensor value of a temperature sensor to the amount of temperature change, an offset adder that adds an offset temperature to an output of the sensor value adder, a response constant determination portion that determines the gain and the time constant, and an offset temperature determination portion. At least one of the response constant and the offset temperature is changed according to a supply voltage or an input voltage.
