Although the stick-slip piezoelectric linear actuators have been widely investigated, the design of stick-slip piezoelectric rotary actuators is rarely reported and the corresponding output performances could be further improved. In this study, by employing a centrosymmetric flexure hinge mechanism, a novel stick-slip piezoelectric rotary actuator was designed. Its structure and working processes were addressed in detail, and the main structural parameters of the centrosymmetric flexure hinge mechanism were designed by the finite-element method. After that, a prototype was fabricated and a series of experiments were performed to test its output performances. The experimental results showed that under various driving voltages, the actuator could output stable angular displacement, and with increase in the driving voltage, the angular speed tended to linearly increase. Under the driving voltage of 100 V and driving frequency of 600 Hz, the actuator reached a maximum angular speed of about 55 000 μrad s−1. The driving resolution of the actuator was 0.34 μrad, and the maximum vertical loading capacity and torque were tested to be 6 kg and 30 N · mm, respectively. In addition, both clockwise and anticlockwise rotations were realized by simply changing the direction of the driving voltage waveform, and furthermore, under the same experimental conditions, very similar output performances were achieved in clockwise and anticlockwise rotations. Compared with some previously reported stick-slip piezoelectric rotary actuators, it was confirmed that the vertical loading capacity and driving resolution of the designed actuator here had been improved, which would be beneficial to its practical application.

“…High-precision positioning is an essential technology in a wide range of fields such as optics, microelectronics, microrobotics, biomedical science, precision measurements and semiconductor-based manufacturing [1][2][3][4][5]. It is not uncommon for a positioning system to be required to deliver stable motion with nanometer resolution and millimeter range while maintaining other positioning characteristics such as large loading capacity, wide speed range, and adequate accuracy [6][7][8].…”

A novel stick-slip type piezoelectric rotary actuator is proposed in this paper. The actuator equips with a parallelogram driving mechanism to generate a pair of variable force couple to drive the rotor. Two piezo-stacks are used to deform the parallelogram driving mechanism to realize large range motions with high resolution in both forward and backward directions. By utilizing pseudo-rigid-body method, geometric model of the parallelogram driving mechanism is established to analyze the motion of the actuator. Finite element analysis is conducted to simulate the deformation of the driving mechanism. A prototype is fabricated and a series of experiments are carried out. The experimental results indicate that the actuator prototype can achieve various angular velocities by changing the driving voltage and frequency and it can output large range rotary motions in both forward and backward directions. The driving resolutions are 0.75 μrad in forward direction and 0.82 μrad in backward direction and the maximum loading capacities are 74 N and 78 N, respectively. The angular displacement outputs under various driving voltages and frequencies show good linear relationships with the time in both forward and backward motions.
