Dynamic analysis of a moving coil-type LOA for load conditions using FEA batch process

This paper deals with the dynamic analysis of a moving coil-type linear oscillatory actuator (LOA) with an asymmetrical magnetic circuit. It is based on a moving model node technique and performed by a two-dimensional finite-element analysis batch process including voltage and kinetic equations. In this model, the moving model node technique offers the more accurate analysis results. The operating characteristics produce different results according to load conditions and present analytical and experimental results on he no-load condition and analytical results on load conditions.
