Abstract:
A multi-axis gimbal assembly includes a spherical armature, a first coil, a second coil, a third coil, a bracket, a stator, and a motor. The spherical armature has first, second, and third perpendicularly disposed axes of symmetry. The first coil is wound about the first axis of symmetry, the second coil is wound about the second axis of symmetry, and the third coil is wound about the third axis of symmetry. The bracket is rotationally coupled to the spherical armature to allow relative rotation between the spherical armature and bracket around only the first axis of symmetry. The stator is rotationally coupled to the bracket to allow relative rotation between the stator and bracket around only the second axis of symmetry. The motor is coupled to the stator and is configured to simultaneously rotate the stator, the bracket, and the spherical armature around the third axis of symmetry.
