Beschreibung
Zusammenfassung:	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 (16, 16a) having a shaft (17, 17a) 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 (18, 18a) is mounted in the housing (16, 16a) concentrically with the shaft (17, 17a). A radial armature (19, 19a) is mounted on the shaft (17, 17a) adjacent the radial magnetic actuator (18, 18a). A set of linear, large-gap, axial magnetic actuators (22, 22a) are mounted in the housing (16, 16a). An axial armature (23) is connected to the shaft (17, 17a) and extends between the axial magnetic actuators (22, 22a). A torque motor (24, 24a, 24b) is also connected to the shaft (17, 17a). A large gap, rotational position sensor (25, 25a) has a first portion connected to the shaft (17, 17a) and a second portion connected to the housing (16, 16a).
