Abstract
Ultrasonic motor (USM) as a new type of driving motor has many good features compared with conventional electromagnetic motor. However, due the content of Pb in the driving element piezoelectric ceramics, Pb(Zrx,Ti1-x)O3(PZT), the application of USM will be restricted from the viewpoint of environmental requirement. In this paper lead free piezoceramics, Mn doped 0.94(Bi0.5Na0.5)TiO3-0.06BaTiO3(BNT-BT), was used as driving element in ultrasonic motor in replacing PZT. Though the piezoelectric property of BNT-BT ceramic is inferior to that of PZT, the USM with BNT-BT driving element shows promising result and potential to replace PZT ceramic in application of ultrasonic motor.
