Abstract

A rotary actuator is shown of the type employing a cylindrical shell rotor moving in a magnetic field extending across an annular air gap. Higher performance is achieved without torsional resonance penalties by employing a rotor having concentric double shell windings in which the shells move in respective concentric air gaps on opposite sides of permanent magnets providing the magnetic field.
