Design and Experimental Validation of Performance for a Maglev Moving-Magnet-Type Synchronous PM Planar Motor

摘要

Among the planar actuators, the SPMPM has the advantages such as no heating problem, high power conversion ratio, and so on. However, conventional moving-coil type SPMPMs are shown to have the limits to expend their working range since they have power cables in the mover. In addition, x- and y- direction motions are coupled each other [1]. In this paper, we propose a novel Maglev moving-magnet-type SPMPM that has a simple and thin stator composed of several PCBs. In order to study the feasibility of the proposed SPMPM, the magnetic flux density and thrust force equations are estimated analytically and verified using the finite-element method (FEM) and experimental works.
