<P>PROBLEM TO BE SOLVED: To rotate a motor, which has a dead band, at extremely low rotational speed. <P>SOLUTION: This motor controller is equipped with a drive voltage regulator which regulates drive voltage and a detector which detects the amount of rotation of a motor. In case that there is a specified voltage range where the rotational speed of the motor becomes zero regardless of the change of the drive voltage, in the property of the motor which shows the relation between the drive voltage applied to the motor and the rotational speed of the motor, the voltage regulator alternately repeats at least once or more the first regulation for regulating the drive voltage so that it may be out of the specified voltage range from within the specified voltage range and the second regulation for regulating the drive voltage so that it may be within the specified voltage range from within the specified voltage range, in case that the motor rotates by the first regulation and that the amount of the rotation detected by the detector is specified one. <P>COPYRIGHT: (C)2007,JPO&INPIT |
