Abstract
A two degree-of-freedom brushless DC motor includes a stator, a rotor, a plurality of distributed stator windings, and a stator voice coil winding. The stator includes an inner stator structure and a plurality of arc-shaped stator poles. The inner stator structure includes a main body and a plurality of spokes that are spaced apart from each other to define a plurality of stator slots. Each arc-shaped stator pole is connected to a different one of the spokes. The rotor is spaced apart from the stator, includes a plurality of magnets, and is configured to rotate about a plurality of perpendicular axes. The distributed stator windings are wound around the plurality of spokes and extend through the stator slots. The stator voice coil winding is wound around the outer surfaces of the arc-shaped stator poles. The arc-shape and spacing of the stator poles define the stator as being spherically shaped.
