Multiple axis actuator
First Claim
1. 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.

Abstract
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.

10. An actuator for inertial stabilization systems comprising:
-
a. a magnetic member having two opposed poles, b. a generally planar platen mounted between said poles and aligned transversely to a line between said poles, and c. at least one double loop spiral winding attached to said platen within the field of said poles, the respective spiral loops of said winding being electrical conductors wound in like direction and mounted on opposite sides of the platen in adjacent parallel planes displaced from each other by a predetermined distance sufficient to develop a pair of like magnetic poles on opposite sides of the platen when the winding is energized, said like poles interacting with the field of said opposed poles to develop a force between the platen and said opposed poles along the line between said opposed poles. - View Dependent Claims (11, 12, 13, 14, 15)

16. Force generating apparatus comprising:
-
an electrically conductive winding in the form of two spirals extending in generally parallel planes displaced from each other by a predetermined distance along a common axis of the spirals, the spirals being wound in like directions parallel to each other and being joined at their centers to provide a single series current path for conducting current in opposite directions in the two spirals to develop a pair of like magnetic poles along said axis on opposite sides of the winding; and means for generating a homogeneous magnetic field encompassing said winding and having a direction generally aligned with said axis in order to develop an axial force on said winding. - View Dependent Claims (17, 18, 19, 20)
