Abstract
This paper introduces a high-force-density linear actuator for an artificial heart, which is based on the concept of a magnetic screw-nut. The novelty of the proposed magnetic screw is adaptation of Halbach permanent-magnet (PM) array disposed helically. PMs are placed on both the screw and the nut. The configuration of the newly designed magnetic screws is presented, and its electromagnetic performances are analyzed. The proposed Halbach magnetized magnetic screw is evaluated as compared with a radially magnetized magnetic screw using the time-stepping finite-element method, verifying the advantages of the proposed structure.
