Magnetic isolating and pointing gimbal apparatus

A magnetic isolation and pointing gimbal apparatus, comprising:

• a housing including an axial module connected to one side of a payload and a torque module connected to an opposite side of the payload;
• a shaft rotatably mounted in the housing and having a centroidal axis extending coaxially within the housing;
• a linear, two axis, large gap, radial magnetic actuator mounted in the housing concentrically with the shaft;
• a radial armature mounted on the shaft adjacent the radial magnetic actuator;
• a set of linear, large gap, axial magnetic actuators mounted in the axial module;
• an axial armature in the axial module, connected to the shaft and extending between the axial magnetic actuators;
• a torque motor in the torque module connected to the shaft;
• and
• a large gap, rotational position sensor in the torque module, having a first portion connected to the shaft and a second portion connected to the housing.
