Abstract

There are produced the detent force caused by slot-teeth structures, end-effect and parallel magnetization of permanent magnet in permanent magnet linear synchronous motor. In this paper, we proposed to establish the auxiliary core for reducing detent force which is generated the discontinuity of magnetic circuits by end effect. The optimal design of the auxiliary core used a finite element analysis and design of experiment. To demonstrate the validity of the paper, the experiment results are compared with analysis ones.
