Based on first principles a dynamical contact model of a Surface Acoustic Wave motor is built. Besides slider behavior also contact point behavior is obtained, which is hard to acquire experimentally. The contact point behavior is used to explain slider behavior like threshold amplitude and like oscillations that are observed in experimental set-ups. This model indicates that an increase of the friction coefficient, the Young modulus and the radius of the spheres at the bottom of the slider gives a raise in both the velocity and traction force.

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
