Abstract
In electromechanical RF switches the rotor is moved between stable angular positions using a DC motor sustained using ball bearings. For space applications, compliant mechanisms may overcome the well-known drawbacks of ball bearings. Nevertheless, high reluctant forces in conventional motors prevent using them as actuators for compliant mechanisms. The design of an actuator to minimize the impact of radial forces and ease the mate with flex mechanisms is presented.
