Claim 12:
13. A moving coil brushless motor, comprising:
an actuator including:
a stator having an outer array of permanent magnets arranged in a first cylindrical configuration and an inner array of permanent magnets arranged in a second cylindrical configuration on an inner back plate:

a rotor including:
a coil assembly including a plurality of coils interposed between the outer array of permanent magnets and the inner array of permanent magnets wherein the coil assembly is disposed to rotate relative to the outer array of permanent magnets and the inner array of permanent magnets;

a center shaft disposed to rotate about a longitudinal axis;
a cylindrical transformer disposed within an interior space circumscribed by the inner back plate, the cylindrical transformer including a primary side and a secondary side wherein the primary side includes a primary coil and the secondary side includes a secondary coil, the primary coil being magnetically coupled to the secondary coil;
primary electronics disposed within the interior space and
secondary electronics disposed within the interior space wherein the primary electronics are in communication with the secondary electronics and wherein the secondary electronics are attached to the center shaft, the secondary electronics being configured to receive power from the secondary coil and to provide current to the actuator;
wherein the outer array of permanent magnets is arranged on an outer back plate such that the outer array of permanent magnets is between the outer back plate and the coil assembly, and
wherein the inner back plate is comprised of aluminum and the outer back plate is comprised of carbon steel.
