Abstract

Planar motor is an important research area in complex automation system. In this paper, a simple and efficient topological structure of Halbach magnet array for planar motor is proposed. The Equivalent Magnetic Charge (EMC) method is used to analyze the proposed array. The calculation results of EMC method, compared with the results of Finite Element Method (FEM) using ANSOFT, indicate that the EMC method is reasonable and accurate. So the EMC method in this paper is applicable to simplify 3D model of complex automation system in order to research the optimal decoupling method and control strategy.
