Abstract
A motor control circuit includes a phase adjuster configured to adjust a phase of a targeted position detecting signal that is present after a subsequent cycle of a reference position detecting signal based on (i) a timing at which a drive current detected by a current-zero point detector becomes zero and (ii) the reference position detecting signal; and a drive controller configured to control a timing at which a drive voltage varies such that the timing of the drive voltage varying matches a timing at which a phase of a targeted position detecting signal changes, and to output the drive voltage.
