Optimum contact conditions for miniaturized surface acoustic wave linear motor

摘要

This paper reports the successful operation of a 70 MHz driving surface acoustic wave (SAW) linear motor with a miniaturized stator transducer. This paper also deals with an investigation into an optimized slider design for the miniaturized SAW linear motor. The performance of three silicon type sliders, with different projection size, was compared. Output forces of the three sliders were measured with change of pre4oad. It was found that the slider with smaller projection tended to produce greater output force.
