The simple structured linear actuator considered in this paper is based on the model, which was called the single-phase oscillating motor, proposed by Jayawant. We have already reported about the static and the kinetic characteristics of the actuator of our model about two cases considered and not considered the magnetic saturation when it was driven by an AC source. Although the theoretical procedue to calculate the characteristics is very simple, the calculated results, in both cases, have shown close agreement with the experimental ones. To improve the actuator for the practical use, some methods will be considered and one of them is to use a DC source instead of an AC source. Using the charged capacitor as a DC supply, a instantenious large current flows easily in the exciting coil in comparison with the case of an AC supply.In this paper, qualitative explanation of the ring motion and calculated results of the ring speed which have good agreement with experimental results are reported.
