First, we propose the current control method to improve the ratio of thrust to current in a maximum thrust/current control for this linear synchronous motor. Experiments are then performed to demonstrate that the proposed current control method is effective at increasing thrust and that the current and input power required to drive this linear motor can be reduced. Next, we propose a new mover that applies the principle of half-wave-rectified self-excitation to the mover with a multi-flux barrier structure. We design the structure of the proposed mover using finite element method. As a result, it is experimentally shown that the thrust density of this linear synchronous motor with the newly designed mover is approximately 30% higher than that of the previously fabricated mover.本誌: IEEJ Journal of Industry Applications Vol.10 No.6 （2021） Special Issue on “ICEMS 2020-Hamamatsu”本誌掲載ページ: 643-651 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/10/6/10_20013528/_article/-char/ja/ Show more
