A multi-axis actuator which provides force along three translational and two rotational axes through the interaction of multiple windings on a single platen which interact with the poles of a magnetic member spaced apart a sufficient distance to allow linear and rotational motion. Said poles are disposed in a parallel relationship to said platen thereby causing a magnetic field to impinge a portion of said platen at right angles thereto. Further, said windings may be disposed so as to generate linear force only, rotational force only, single or multiple translational forces only or force about rotational axes only or any combinations of the foregoing necessary for the desired force generation.

A force producing apparatus comprising: a. a single pair of opposed magnetic poles for establishing a monogeneous magnetic field having flux lines aligned in the same direction from pole to pole; and b. means for producing force in a direction substantially parallel to the flux lines of said magnetic field comprising at least a pair of electrically conductive spiral windings positioned within said magnetic field for interacting therewith, the windings of said pair being wound in like directions in adjacent parallel planes generally orthogonal to said flux lines and connected together at the inner ends of the spirals, said windings being displaced from each other in a direction aligned with the magnetic field by a predetermined distance sufficient to develop, when the windings are energized, like magnetic poles on opposite sides of said winding pair for interacting with said magnetic field to develop a force in the direction of said field.
