It is because of these characteristics, piezoelectric motor technology in the century is obtained a rapid development and application, and international experts pay more and more attention to of the new actuator research and development, trying to realize it in some areas of large-scale production to replace the traditional assolenoid style motor.
Multi-dimensional movement piezoelectric motor Jilin university of technology of scholars have proposed a 2-d piezoelectric motor, the translation of the motor, rotate the motor of multiple types, the characteristics of the motor is platform for rectangular plates or circle, 3-4 installed above a small pieces, the workbench a ceramic parts, after electrify incentives, in vibration mode, the small piece of hold up the upper portion of the parts of rotating or pan, the piezoelectric motor features are: 1) Through a single on the oscillator piezoelectric ceramic partition design, and USES the incentive piezoelectric resonators on different parts of the piezoelectric ceramic's way, can make more controllable piezoelectric motor produce planar motion freedom. 2) Piezoelectric motor piezoelectric ceramic division, raised the symmetry of piezoelectric effect is the working performance of the motor one of the main factors. 3) The load of the working performance of piezoelectric motor has a
A, piezoelectric resonators is A central part of low frequency motor, so in design piezoelectric vibration and before A rectangular piezoelectric resonators slightly different, first is because of the shape of the piezoelectric ceramic ring different must make corresponding boards; In the adhesive circular piezoelectric vibration son, must let substrate and piezoelectric ceramics in adhesive for surface contact, this is about to pay attention to in choosing the piezoelectric ceramic note that plane degree, or piezoelectric resonators in vibration in the process of piezoelectric ceramic loose or even broken, the resonance frequency with bonded is not prone to change, and produce less than the best effect.
Rely on piezoelectric equation and pre-tightening force equation analysis, incentive stress analysis for ceramic materials to meet the requirements of the low frequency drive the lower conditions, for ceramic material parameter selection to provide the reference.
