PURPOSE:To conduct current, which generates a torque in a motor, through the motor when the voltage commanding value of the result of the operation of a microcomputer is small and eliminate blind sector and follow-up delay, by obtaining an offset value by a speed commanding value. CONSTITUTION:A microcomputer 31 reads the data of a position detecting unit 36 in accordance with a flowchart. The microcomputer 31 converts a speed commanding value into an offset value by a predetermined converting means and adds the offset value to the result of the operation thereof to output it to a PWM unit 32. According to this method, the blind sector of a motor, which is generated when the result of operation of the microcomputer 31 is of small value, can be eliminated. |
