In order to develop high precision, large travel, heavy thrust linear piezoelectric motor, a marching type linear piezoelectric motor based on the piezoelectric stack was proposed. The operating principle of the motor was presented, the structure of the motor was designed, a prototype was made and the experimental studies were carried through. The experimental results showed that within a certain...
In order to reduce the effect of the mover surface roughness on the piezoelectric linear motor performance, a non-resonant vibration linear motor based on displacement amplification structure has been investigated. The moter structure was designed in which a lever mechanism was used to achieve amplification of the piezoelectric stack vibration amplitude. The stack vibration amplitude was amplified...
With the rapid development of modern precision manufacturing industry, actuators with high resolution and long stroke are needed in many application fields. Because of the unique advantages such as self-locking on the power off, compact structure, fast response etc., piezoelectric actuators have been taking place of the traditional actuators which are based on the principle of electromagnetic induction...
Summary form only given. Based on the piezoelectric ceramics stack had a big amplitude of displacement during low frequency, a new type of piezoelectric linear motor based on non-resonant vibration was proposed. The working principle of the motor was presented, the structure was designed by finite element software, and a prototype was made. The mechanical property of the motor was preferable during...
