In order to meet the actual requirements of ultrasonic motor better , Nb205, NiO, Fe203 ternary 75khz piezo discs transducer were used. Doping PZT piezo ceramics, PZT material not only has the characteristics of good stability of time temperature and low loss of resonance frequency, but also has good dielectric and piezoelectric properties. PZT piezo material piezo discs of piezoelectric ceramics are used in ultrasonic motors. 


The results show that the performance of the motor is better than that of Japanese motors, and its overall performance is better. Prepared xPMnS with high performance. The performance of quaternary piezoelectric ceramic materials piezo discs transducer can meet the requirements of high-power ultrasonic motors. The lead magnesium niobate-lead titanate (PMN) is developed for ultrasonic motor has been proved to work at a low temperature of 200°C, and its performance can reach the current PZT room temperature performance, It is the working frequency and normal temperature environment. The result is similar, making it possible to use PMNs to develop various types of ultrasonic motors that are used in extreme environments. 


PZT piezoelectric ceramics are used in traveling wave ultrasonic motors to further improve the precise positioning of the motor. PZT-8 is used in ultrasonic motors to study the mechanical properties of the motor at multiple high temperatures. The relaxation of ferroelectric piezo element sensor crystal is ultrasonic motor research work was carried out. Substitution with Sb, Li and Mn provides excellent material properties and is expected to become a material for high-power devices. With the miniaturization of piezo cylinder crystal, the research direction of piezoelectric ceramics has been turned to piezoelectric films.The micro-ultrasonic motor was successfully developed by directly depositing a PZT piezoelectric film on a metal stator using a sol-gel method with a maximum speed of 650 r/min and a maximum output torque of 0.22 N. It was developed into a piezoelectric motor with a T diameter of 1.6 mm, an inner diameter of 0.8 nlnl, and a length of 6 mm. The maximum power is 45 mW and the speed is 45 rad/s.
