Design of mover structure of a moving-magnet type linear motor utilizing magnetic-flux concentration-type permanent magnet arrangement

This paper presents a moving-magnet type linear synchronous motor designed by using magnetic-flux concentration-type permanent magnet arrangement. The arrangement of permanent magnets in the mover structure is optimized with the three-dimensional finite element method in order to improve thrust characteristics. The calculated results are verified in comparison with the measured ones with the manufactured prototype machines.
