Patent ID: 7071591

Claim:
A servo mechanism, comprising: a coil assembly, said coil assembly comprising at least one motor coil integrated with a printed circuit board; and a magnet assembly, said magnet assembly comprising a one-piece continuous rare earth magnet having at least two sets of poles and being configured in a full ring shape; wherein said coil assembly and said magnet assembly are rotatably coupled together in operative relationship; wherein said coil assembly further comprises a coil support platter rotatably coupled to said magnet assembly, said at least one coil being fixedly coupled to said coil support platter; wherein said coil support platter comprises a first printed circuit board having first circuitry; wherein said magnet assembly further comprises a second printed circuit board having second circuitry, said second printed circuit board being fixedly coupled to said magnet; wherein said servo mechanism further comprises a dynamic signal interface between said first circuitry of said first printed circuit board and said second circuitry of said second printed circuit board; wherein said first printed circuit board and said second printed circuit board define a slip ring boundary therebetween; and wherein said first and second circuitry comprise position feedback circuitry.
