Researching for the piezoelectric motor

Piezoelectric motor for piezoelectric plate datasheet is a new type of micro-motor driven by piezoelectric material. It uses the inverse piezoelectric effect to make the stator body produce flexible fluctuations, and then flexible piezoelectric transducer for the vibration energy into the torque output of the rotor under the vibration friction of the stator surface particles. Piezoelectric motors for electrical model piezoelectric transducer have the characteristics of small size, light weight, simple and compact structure, accurate positioning, fast response, low speed and large torque output. Piezoelectric plate price can be used in micro-mechanics, robotics, medical equipment, aerospace and automatic control fields. In recent years, piezoelectric vibration sensor have become an important aspect of piezoelectric material application development. Piezoelectric ceramic as a piezoelectric motor has core components, piezoelectric plate sensor is to improve its overall performance, will be able to improve the performance of piezoelectric motors, piezoelectric motors for a wide range of applications to lay the material foundation. Ultrasonic medical treatment is with the main properties of piezoelectric ceramics : (1) good mechanical strength, can work under high power, or prone to fracture; (2) high piezoelectric constant d33, to achieve low voltage drive and large output Torque.(3) high electromechanical coupling coefficient kp; (4) low dielectric loss tan value, high mechanical quality factor Qm, can improve the piezoelectric transducer (oscillator) efficiency and reduce losses. In fact, piezo rectangle sensor is hard to have a piezoelectric ceramic material that meets all these requirements simultaneously. In actual use, need to be based on different occasions and the main contradiction to choose. Emphasize the energy consumption applications, the use of hard piezoelectric ceramics, and in the need of lower voltage, broadband, high speed of the occasion, the use of soft piezoelectric ceramics more appropriate. The working environment is high temperature, you should Curie temperature as an important indicator.
