Description
Summary:This paper presents a characteristic analysis of a tubular-type permanent-magnet (PM) linear magnetic coupling (TLMC) based on analytical magnetic field calculations. First, the analytical solutions for magnetic fields generated by PM are derived on the basis of a magnetic vector potential and a 2-D polar coordinate system. Next, the magnetic force is also determined on the basis of these solutions. The magnetic field and force obtained by the analytical method are compared with those obtained by the finite-element analysis and experiment, which validates the analysis methods presented in this paper.
