ABSTRACT:
A system and method for a multiple degrees of freedom motor includes an output shaft. A stator is provided having at least a first lamination stack. Each lamination stack has an interior curved surface. The lamination stacks are disposed adjacent the output shaft. A rotor is fixed to the output shaft and movably supported adjacent the stator with an air gap disposed between the rotor and the stator. The rotor includes at least one magnet disposed thereon. The magnet is movable along the interior curved surface of the lamination stacks in directions defining at least a first degree of freedom. The rotor is biased toward a base position along at least one degree of freedom.
