3-D analysis of permanent magnet linear synchronous motor with magnet arrangement using equivalent magnetic circuit network method

In this paper, the fields and forces of permanent magnet linear synchronous motors (PMLSM) with segmented or skewed magnet arrangement are analyzed according to length of segment or skew. And, the effects according to the lateral overhang of magnet are investigated. For the analysis, 3-dimensional equivalent magnetic circuit network (3-D EMCN) method is used. The analysis results are compared with the experimental ones and show a reasonable agreement.
