ABSTRACT:
A rotary shaft position control apparatus in which the rotary shaft is stopped in one revolution. After detection that a flux emitter on the shaft has passed a position detector, the shaft speed is set to a first speed. The first speed is continued until a product of the first speed and the elapsed time at the first speed after passing the position detector equals a predetermined constant. Then, the speed is reduced to a second speed. Finally, the shaft is stopped when the flux emitter again passes the detector.
