| Outline of Final Research Achievements |
In most conventional motors, secondary current is supplied by magnetization or electric field generated by electric potential or electromagnetic induction. However, there is a possibility that polarization current can be utilized as secondary current. We propose a new motor that utilizes polarization current generated by varying electric field between two conducting plates of a capacitor. Simultaneously a series coil generates varying magnetic field. As a result a dielectric object placed at the secondary side experiences one-way Lorentz force perpendicular to both polarization current and magnetic field. In addition, the capacitor and the coil constitute a resonant circuit which brings large current at the resonance frequency. In this study, we measured frequency response of the proposed motor in high frequency domain and derived a precise equivalent circuit explaining the measured impedance well. We observed average force of 2.8mgf for a dielectric object through experiments.
