ABSTRACT:
Apparatus which has a permanent magnet rotor magnetically coupled to a control field permanent magnet, the magnets being rotatable about respective rotational axes of support that are perpendicular to one another. The magnetic axis of each magnet is perpendicular to the rotational axis of that magnet, so that the rotor magnet changes in attitude about its rotational axis in response to a change in the magnitude and sense of the control field component perpendicular to the rotational axis of the rotor magnet. Such a change of the perpendicular control field component is caused by turning the control field magnet about its rotational axis through motor-driven reduction gearing including a worm and gear combination which holds the rotor magnet at its adjusted attitude after the motor is deenergized. The attitude adjusting effect of the control field magnet on the one rotor magnet is multiplied by arranging additional rotor magnets, similar to the one rotor magnet, so that all of the rotor magnets have their rotational axes in spaced parallel relationship with one another in a common plane parallel to the rotational axis of the control field magnet and have the same magnetic coupling relationship with the control field magnet.
