Abstract:

The two-dimensional finite element analysis model of tubular permanent magnet linear motor (TPMLM) was established. The field distributions and air-gap magnetic field density under no-load condition were analyzed. No-load and load induced electromotive force are calculated. An experiment was carried out, the result showed that the analysis methods are correct and effective.

Key words: tubular permanent magnet linear motor (TPMLM), Halbach, finite element method (FEM), magnetic field analysis, wave power
