The operation of a linear or rotary ultrasonic motor relies on the production of an elliptical vibration at the surface of the stator. To achieve a suitable vibration state, many ultrasonic motors use a combination of structural modes of the stator.

A resonant magnetostrictive motor was built and tested. Its stator modules are made of a ring and two Terfenol-D linear actuators. Two resonant modes of the modules (a translation mode and a flexure mode) are coupled in order to produce elliptical vi
