A traveling wave miniature ultrasonic motor has been developed using a helical coiled waveguide as a stator, and it has been applied to an intravascular ultrasound (IVUS) probe. In this motor, the elliptical motion of the surface particle due to flexural ultrasonic waves drives the rotor which can be placed inside or outside adjacent to the stator via frictional force. However, the fact that the rotational direction of the outer rotor is the reverse of that of the inner rotor at low frequencies of the flexural wave has not been clarified theoretically. In this study, the surface particle motion is investigated through finite element method (FEM) simulations, and the basis of the rotational directions is clarified.
