摘要

The present invention is intended to remove undesirable effects on various physical quantities due to temperature changes in a motor for driving a throttle valve without causing simple or alternative problems. The present invention also provides a technique for electrically measuring the temperature of the motor. In view of this point, the present invention is provided with a compensating apparatus for detecting the impedance of the motor winding and / or changing the temperature of the motor and compensating the power supplied to the motor. The temperature of the motor is estimated from the current flowing through the motor and the applied voltage.
