| Abstract(in English) | Authors developed a traveling-wave-type ultrasound motor using a helical coiled waveguided as a stator. The motor has an advantage of miniaturization due to the simplicity. A rotor can be placed outside or inside adjacent to the stator: outer rotor type and inner rotor type structure. In previous study, we confirmed that rotation direction of the outer rotor type CS-USM with low driving frequency is reversed to that with high driving frequency. In this study, to clarify the phenomenon, we examine the surface particle motion of helical coiled waveguide. As a result, although both γ- and θ-directional phases of the inner surface with low driving frequency coincide with those of straight line waveguide; the phase dirreference between θ-directional phase of inner and outer surfaces is 180 degrees, θ-directional phase of the outer surface is shifted 180 degrees to that with high driving frequency; the phase difference between inner and outer surfaces is 0 degree. |
