Abstract
An actuator that has two or more degrees of freedom that moves a payload are described. The actuator may have two members, an actuator stator and an actuator armature, with the ability to move relative to each other in two or more degrees of freedom.
Claims13
An actuator providing movement with at least two degrees of freedom, comprising:
- an actuator stator body with a concave spherical surface;
- at least two overlapping sets of electric conductors located in proximity to the concave spherical surface wherein each set of the electric conductors is not parallel to the other set of electrical conductors and may conduct current independent of the other set of electrical conductors;
- a support structure extending vertically away from said actuator stator body, the support structure having a first end attached to a center point of the concave spherical surface and a second end vertically away from the actuator stator body;
- and
- an actuator armature structure mounted on the second end of the support structure that is free to pivot about the center point of the concave spherical surface, wherein the actuator armature has at least one magnet pole held in proximity to the concave spherical surface to move the actuator with at least two degrees of freedom.

An actuator that provides movement with at least three degrees of freedom, comprising:
- an actuator stator body with a concave spherical surface;
- at least two overlapping sets of electric conductors located in proximity to the concave spherical surface wherein each set of the electric conductors is not parallel to the other set of electrical conductors and may conduct current independent of the other set of electrical conductors;
- a support structure extending vertically away from said actuator stator body, the support structure having a first end attached to a center point of the concave spherical surface and a second end vertically away from the actuator stator body;
- and
- an actuator armature structure mounted on the second end of the support structure that is free to pivot about the center point of the concave spherical surface, wherein the actuator armature has at least two magnet poles held in proximity to the concave spherical surface to move the actuator with at least three degrees of freedom.
