Abstract
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.
