Abstract

<p>This paper presents a novel magnetic lead screw actuator without helical permanent magnets. Magnetic lead screw actuator is high efficiency due to its non-contact transmission. It is expected to be applicable to interactive robots with human because of its compliance to external forces. The proposed actuator has simple structure comparing to the conventional magnetic screws. The result of the force calculation and structure optimization employing 3-D finite element method is reported.</p>
