A magnetic isolation and pointing gimbal apparatus provides support functions and multidegree of freedom pointing capability and simultaneous six degree of freedom bi-directional disturbance isolation. This is accomplished by integrating the support, isolation and pointing functions within one contiguous gimbal assembly. The apparatus comprises a housing having a shaft rotatably mounted therein such that the centroidal axis of the shaft is coaxial with that of the housing. A linear, two-axis, large gap, radial magnetic actuator is mounted in the housing concentrically with the shaft. A radial armature is mounted on the shaft adjacent the radial magnetic actuator. A set of linear, large gap, axial magnetic actuators are mounted in the housing. An axial armature is connected to the shaft and extends between the axial magnetic actuators. A torque motor is also connected to the shaft. A large gap, rotational position sensor has a first portion connected to the shaft and a second portion connected to the housing.

Magnetic isolating and pointing gimbal apparatus

A transformer for coupling electrical power from a stationary location to a moving location with a minimum of disturbance forces between the stationary and moveable components. The transformer is particularly adapted to coupling power to a magnetically suspended platform. The transformer includes an enclosed core housing two windings, a stationary primary coil, and a secondary coil free to move linearly and angularly over a limited displacement, where the secondary coil is affixed to the moveable platform, thereby enabling energy to be extracted for powering apparatus mounted within the platform.

Forceless non-contacting power transformer

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.
