Reducing the thrust ripple is one of the important analysis and research contents of Permanent Magnet Linear Motor (PMLM). The thrust ripple was mainly caused by the cogging force and the end force. In this paper, in order to reduce cogging force in PMLM, the mechanism of cogging force was analyzed. And the analytical expression of the cogging force was got using energy method and Fourier expansion. Based on the expression, the effect of slot-poles number, pole-arc coefficient and slot-opening coefficient on …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
