Abstract
With the progress of linear motors and permanent magnet materials, three kinds of magnetization methods have developed for permanent magnet linear motor. Based on the analysis of magnetic field distribution of radial, Halbach and tangential magnetization, the impacts are investigated of these methods on performances of permanent magnet linear synchronous generator (PMLSG) through simulation. Advantages and disadvantages of these methods are unveiled by studying and comparing their flux linkage, magnetic detent force and EMF harmonics. A conclusion can be drawn that radial magnetization suits PLMLSG better.
