Abstract:This study presents the theoretical equivalent circuit analysis of a single-phase rotary wedge-wave ultrasonic motor (WW-USM) that was verified through simulations and experiments involving switching from the ON to the OFF transient state. The linear equivalent circuit model described herein has an initial condition and is used to derive transient wave motion responses by simple closed-form equations. The responses of the motor stator and the effects of the ON/OFF switching times of the AC source on the motor … Show more
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.
