Apparatus for holding a series of permanent magnet rotors having parallel transversely spaced coplanar rotational angles firmly at any of a wide range of desired angles without consumption of energy, the angles being linearly adjustable independently of rotor spacing and with constant torque sensitivity, by mechanically linking each rotor to an adjacent rotor to form pairs and arranging the magnetic axes mutually perpendicular and perpendicular to the axes of rotation, coupling each rotor to a direct magnetic control field component perpendicular to the plane which is common to the rotor axes and varying the amplitude ratio of the field components coupled to the rotors of a linked pair according to the tangent of a control angle to turn the rotors through a corresponding angle.
