Abstract
This paper proposes a new electromechanical energy conversion system, called Field Modulated Magnetic Screw (FMMS) as a high force density linear actuator for artificial heart. This device is based on the concept of magnetic screw and linear magnetic gear. The proposed FMMS consists of three parts with the outer and inner carrying the radially magnetized helically permanent-magnet (PM), and the intermediate having a set of helically ferromagnetic pole pieces, which modulate the magnetic fields produced by the PMs. The configuration of the newly designed FMMS is presented and its electromagnetic performances are analyzed by using the finite-element analysis, verifying the advantages of the proposed structure.

The electromagnetic characteristic of FMMS is calculated by finiteelement analysis
Summary
Transplantation of donor and implantation of artificial heart are the major treatment of terminal heart diseases. Due to the shortage of natural hearts, artificial heart (AH) is the best treatment option for many heart failure patients.[1] The AH drive device must meet a variety of requirements, such as small size, high reliability, high power density and light weight.[2] Existing electric drive based AHs employ rotary blood pumps but suffer from damage to blood cells.[3] Linear AH motors were proposed to solve this problem, but its force density was relatively poor.[4] double stator structure and vernier topology can improve the force capability of the linear AH motor, they suffer from difficult manufacture and low power density, respectively.[5,6]. The major objective of this paper is to evaluate and confirm the advantage of the FMMS
