ABSTRACT: Theinputimpedanceisveryimportantfor ultrasonicmotors indrivingsystem. Thefiniteelement analysis (FEA)methodispresentedforstudyingtheinputimpedance characteristicof travelingwave typeultrasonicmotor. TheFEA simulationmodeloftheultrasonicmotorstatorwith60mmin diameterisestablished,andtheimpedancecharacteristicis automaticimpedancemeasuringmethodbasedontheVirtual motorstatoristestedbythismethodalsointhefrequency paringwithtestingresults, thecalculatingresultsofinputimpedancecharacteristicwith theFEAmethodarevalid.
