SPHERICAL VOICE COIL BASED RESOLVER SYSTEM

Abstract:

A spherical resolver system includes a spherical body, an outer body, a first sensor coil, a second sensor coil, a third sensor coil, a first primary coil, and a circuit. The spherical body has a first axis of symmetry, a second axis of symmetry, and a third axis of symmetry, and the first, second, and third axes of symmetry are disposed perpendicular to each other. The circuit is coupled to the first primary coil and is operable to supply a first alternating current (AC) reference signal (V.sub.r1) to the first primary coil, whereby a first sensor signal (V.sub.x) is selectively induced in the first sensor coil, second sensor signal (V.sub.y) is selectively induced in the second sensor coil, and a third sensor signal (V.sub.z) is selectively induced in the third sensor coil, and supplies one or more signals representative of the sensor position.
