<P>PROBLEM TO BE SOLVED: To provide a method of controlling the initial current value in driving a motor. <P>SOLUTION: In a first process, a motor constituted of a coil 10 is driven, using a method of outputting a phase to the coil 10 connected with a drive unit 20. In a second process, a detecting unit 40 detects magnetic pole change generated during operation of the motor, and generates and outputs a signal. In a third process, a control unit 30 determines whether the motor is in operation or not, depending upon whether the detecting unit 40 connected with the control unit 30 is generating a signal or not. In a fourth process, the control unit 30 receives the signal from the detecting unit 40, and controls the drive unit 20 for phase output to the coil 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
