LIU Jian-fang, YANG Shu-chen, YANG Zhi-gang, CHENG Guang-ming. Study on precision PZT rotary step actuator with inner anchor/loosen[J]. Editorial Office of Optics and Precision Engineering, 2006,14(4): 594-601DOI:
A new precision rotary PZT actuator was proposed to improve its drive capabilities. Based on the piezoelectric (PZT) technology and the bionical principle
the PZT actuator uses a stator inner anchor/loosen and a distortion structure of thin shelf flexible hinge to improve the stability of anchor/loosen and step rotary. With a characteristic analysis from the finite element method
the results show that the new rotary PZT actuator works with high frequency (40 Hz)
high speed (325 rad/s)
large travel (360)
high resolution(1 rad/step) and high torque (30 Ncm) and it will be suitable for application to large travel and high resolution driving device
optical engineering
precision positioning and some micro-manipulation field.
