Proposal of a Three-Degree-of-Freedom Linear-Rotational Resonant Actuator and Inverter Topology

The aim of this study is to propose a new three-degree-of-freedom linear-rotational resonant actuator and its controller. To realize all of the resonant motion, four-phase coils and three sets of the permanent magnet are arranged symmetrically. In addition, in order to control the proposed actuator, inverter topology with six-switches is presented. Parameter characteristics obtained through finite-element analysis support the validity of the proposed actuator. Finally, dynamic simulation is performed to verify the effectiveness of the proposed actuator.
