Electromagnetic Design of a Novel Linear Maglev Transportation Platform With Finite-Element Analysis

In this paper, a novel maglev transportation platform is developed for ultra-precision linear motion with large travel range, and an optimized decoupled electromagnet spatial distribution of this platform is designed with finite-element analysis. The platform consists of a levitation subsystem and a propulsion subsystem. The levitation subsystem uses six pairs of electromagnets to steadily suspend the moving platform over the guideway, and then the propulsion subsystem drives the moving platform run along the guideway. To minimize the magnetic coupling among electromagnets, the magnetic field analysis of electromagnets is executed with the finite-element method. Through the analysis, an optimized spatial distribution and type of electromagnets are found. Finally, the maglev transportation platform is manufactured, assembled, and mechanically adjusted.
