We have examined optimum pressing force, namely, pre-load for a slider to obtain superior operation condition of a surface acoustic wave motor. We used steel balls for sliders. With a permanent magnet the pre-load was controlled. The steel balls that we used were 0.5, 1 and 2 mm diameter to change contact conditions such as contact pressure, contact area and deformation of a stator and the slider. The stator transducer was lithium niobate 128 degrees Y-rotated X-propagation substrate. Thedoi:10.1109/ultsym.1996.583994 fatcat:aeq7u677brdz3btklah2rmv6hi
