ABSTRACT:
A permanent magnet, direct current torquer for a gyroscope of the two-degree-of-freedom, free-rotor, force-rebalanced type includes a primary magnetic circuit having axially polarized permanent magnets, preferably of the samarium cobalt type, and flux focusing means cooperating therewith for directing the axial flux thereof in a radial direction for reaction with fields of concentric, axially-effective, frame-mounted torquing coils. The focusing means includes secondary annular axially-polarized magnets and a further magnetic circuit to minimize leakage flux. The primary and secondary annular magnets closely surround the rotor axis so that the amount of inertia of the rotor is minimized, desirably improving the sensitivity of the instrument.
