ABSTRACT:
An electromagnetic circuit that may be advantageously employed in an articulated camera, such as a CCTV camera, as a part of a servo mechanism to directly drive the camera and optical lens assembly, for example, in the pan and/or tilt axes. In one embodiment, the coil assembly of the servo mechanism may comprise four separate coils that rotate about the center of the ring shape of a single one-piece ring-shaped permanent magnet that has been pre-magnetized in two pair of opposing polarities. The magnet assembly that includes the magnet ring, may be bonded to a circular plate made of ferrous metal.
