This paper deals with the influence of meStator Wind chanical resonance on the dynamic performance of a tubular Air-gap linear actuator with Halbach array. Control parameters are PMs obtained from both measurements and analytical solutions. And then, the voltage and the motion equation of the tubular linear actuator are established. In particular, by expressing mechanical components as the motional impedance, this paper investigates the variation of power dissipated in the linear actuator with spring vs. frequency. Finally, the simu-N lations and experiments for dynamic characteristics of the moving-magnet linear actuator with spring are presented for W various values of frequency.Fig. 1. Structures of tubular linear actuator with Halbach array.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
