PURPOSE:To facilitate the regulation of the position by flowing a DC current of the prescribed phase and prescribed level to an armature winding, and detecting the displacement of the detector and a sole motor on the basis of a signal from the detector. CONSTITUTION:When a detector regulating mode switch 17 is selected, a switch 19 is shifted, the prescribed current is output to a multiplier 12 from a pole position regulator 18, and the prescribed value is simultaneously preset to a counter 10. A motor 4 generates a torque to dynamically balance from the position corresponding to preset data to the counter 10 to the position delayed at 90 deg. of electric angle, and stopped. The output value of the counter 10 is checked by a data discriminator 20 in this state, and if the value is in the prescribed range, a light emitting diode 21 is fired. The detector 5 is positioned so as to fire the diode 21. |
