Abstract :
This paper deals with the effect of lateral force in the permanent magnet linear synchronous motor (PMLSM) for the guidance in magnetic levitation stage. In order to analyze not only overhang effect of the PMLSM, but also lateral asymmetry of secondary (mover), 3-dimensional equivalent magnetic circuit network (3-D EMCN), considering movement of the secondary in lateral direction is introduced. The current vector control scheme is applied for the analysis of propulsion, levitation, and lateral force in the PMLSM for magnetic levitation stage.
