Summary form of only given: To reduce the detent force by end effect, the auxiliary core which has the independent magnetic circuit is proposed in this paper. The auxiliary core is designed by the DOE (Design of Experiment) and FEA. And the prototype machine of auxiliary core is made and experimented. To demonstrate reduction effect of the detent force by the auxiliary core, the experimental results...
This paper proposes a novel technique to reduce the detent force in permanent magnet linear synchronous motor (PMLSM) using auxiliary poles technique. The detent force that is caused by the attraction between permanent magnet (PM) and the iron core without input current can be divided into two components: the slot effect and the end effect. To reduce these two effects, we analyze the characteristics...
