The contact states of the slider and stator substrate greatly affect the drive performance of a surface acoustic wave motor. The contact states are determined by factors such as the friction coefficient, vibration amplitude, rigidity of the contact surface, contact time with the Rayleigh wave, and slider speed. A model was proposed that represented the relationship between these factors and the drive performance. However, guidance has not been provided on how these values should be changed to improve the drive performance. In this research, we use a friction drive model we proposed to analyze the effect of the changes in these parameters on the drive performance and to discuss the motor design and the drive conditions based on evaluations from the perspectives of the drive power, output, and efficiency. © 2004 Wiley Periodicals, Inc.
