ABSTRACT:
An electromagnetic position control apparatus including a rotary sphere having a permanent magnet. The rotary sphere is rotably supported within a spherical hole formed at a crossing portion of a cross-shaped yoke. Coils are used to create magnetic fields at the rotary sphere. The position of rotation of the rotary sphere is controlled in three dimensions by means of changing the intensity of the direct current supplied to the coils or the duty cycle of the pulse current supplied to the coils to change the intensity of the magnetic fields.
