This paper examines the performance enhancement of a newly designed ultrasonic motor by using single crystalline piezo-materials Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMNPT) and Pb(Zn1/3Nb2/3)O-3-PbTiO3 (PZNPT). From numerical simulations, it is found that PMNPT and PZNPT can greatly improve the mechanical performance of the motor.
