ABSTRACT:
Current detecting circuits are provided for all phases of a motor driving circuit. A motor control portion is provided with a correction value calculating unit for calculating a correction value by dividing a total sum of motor current values based on detecting signals detected by the current detecting circuits of all the phases by a number of the phases of a motor and a motor current value correcting unit for correcting the motor current values by subtracting the correction value from the motor current values based on values of currents actually flowing in the respective phases of the motor. Thereby, the motor is driven.
