Claim 0:
1. A device comprising:
a rotor platform that rotates about an axis of rotation, the rotor platform including a rotor planar mounting surface;
a rotor coil comprising a first plurality of conductive loops disposed along the rotor planar mounting surface;
a stator platform including a stator planar mounting surface;
a stator coil comprising a second plurality of conductive loops disposed along the stator planar mounting surface; and
a plurality of light sources on at least one of the rotor planar mounting surface or the stator planar mounting surface, for emitting light toward the other of the rotor planar mounting surface or the stator planar mounting surface,
wherein at least one of the first plurality of conductive loops of the rotor coil or the second plurality of conductive loops of the stator coil are patterned on a printed circuit board (PCB) and concentrically arranged about the axis of rotation.
