It is important to improve efficiency of surface acoustic wave motors in order to achieve their commercialization. In the present research, the energy of the surface wave, which has previously not been used effectively for driving the slider, but been consumed in sound‐absorbing materials, is now circulated by two techniques, so that the surface wave is excited efficiently. Trial fabrication of surface acoustic wave motors using the energy circulation methods is carried out. It is confirmed that the traveling wave can actually be excited. In addition, the effectiveness of the energy circulation method is demonstrated by comparison of the driving performance with that in the absence of energy circulation methods. © 2003 Wiley Periodicals, Inc.
