Paper Abstract

In optical systems, where the positions of such components as mirrors must be controlled in six degrees of freedom (DOFs), magnetic bearings can impart forces and torques to the suspended component without rigidly constraining its DOFs, and obviate the complex flexures typical of conventional designs. Attention is here given to a magnetically suspended linear bearing employing variable-reluctance actuators to control three rotational and two translational DOFs, as well as to a linear motor charged with control of the sixth DOF. Applicability to vibration isolation and optical line-of-sight stabilization are noted.
