Thereby, a rotor magnet 5 starts to rotate with this rotary magnetic field. A detecting circuit 16 detects rotation of the rotor magnet 5 from output signal of the Hall elements 3, 4. In the forcible magnetic field corresponding to a single rotation because of the friction of the rotor magnet 5 is large, if the rotor magnet 5 does not rotate, a detection signal from the detecting circuit 16 is not output to a judging circuit 10 and the judging circuit 10 repetitively generates forcible magnetic field while the changeover switch 11 is being connected to the forcible magnetic field generating side.  When the detecting circuit has detected rotation of the rotor magnet 5, the changeover switch 11 is switched via the judging circuit 10. Thereafter, the rotary magnetic field is given on the basis of the signal from the Hall elements 3, 4.
