Topology optimization was used to design the stator structure. In contrast to traditional travelling wave ultrasonic motors, which require two modes to be driven 90° out of phase, only one amplifier is required to drive the proposed device. A prototype device was characterised experimentally and was used to drive a linear bearing at 14 mm/s reversibly and a force of 50 mN was developed by the motor.enLissajous patternPiezoelectric ultrasonic motorUltrasonic linear motorApplied mechanicsNovel ultrasonic motorSACAM 2010Conference PresentationM'Boungui, G., Loveday, P.
