“…The hybrid mode actuation [69][70][71][72][73][74] means that the piezoelectric ceramics in the stator composite elastomer are used to excite the vibration modes of the same frequency, where one vibration mode is used to provide positive pressure between the stator and the mover, and the other vibration mode provides driving force by means of the friction between the stator and the mover, so that the mover can generate linear or rotary motion. A clamped V-type linear ultrasonic motor [75] was proposed for an absolute gravimeter based on a new clamping method with sufficient tangential rigidity and the ability to facilitate preloading, which achieved the maximal thrust and velocity of 43 N and 1400 mm s À1 , respectively.…”

Piezoelectric actuation technology has been widely used in various precise‐oriented fields. Its notable advantages include high resolution, rapid response speed, output force with high density, and immunity to electromagnetic interference. Characteristics of cross‐scale and multiple‐degree‐of‐freedom (multi‐DOF) output motions are of utmost importance in the context of micro‐/nanopositioning technology. For decades, researchers have been working to develop various piezoelectric devices that exploit these important properties. In this review, a comprehensive review of recent research efforts in the field of cross‐scale multi‐DOF piezoelectric drive technology is provided. To commence, it provides an in‐depth exploration of the unique advantages associated with piezoelectric actuation, demonstrating them through comparative analyses with alternative actuation methods. Subsequently, the complexity of piezoelectric cross‐scale motion is introduced, and the multi‐DOF piezoelectric motion is classified in detail. Furthermore, the practical applications of multi‐DOF cross‐scale piezoelectric actuation technology are systematically elucidated, highlighting its versatility and suitability in real‐world environments. Finally, an in‐depth discussion that addresses the challenges encountered in the field is provided, and the prospective directions for further developments in piezoelectric actuation technology are outlined. This scholarly contribution plays an important role in guiding future research and innovative initiatives.

“…Nonetheless, the piezoelectricity of single-crystal PMN-PT at liquid nitrogen temperature also displays more substantial electromechanical properties than PZT ceramics at room temperature [28]. Liu et al [29] designed a new rotary ultrasonic motor in which eight PZT ceramics were bonded to a square duralumin alloy frame. The motion behaviour of the driving tips was studied, the prototype was fabricated and tested to check the viability of the new design.…”

The advent of smart materials and modern control theory has seen the rapid development of ultrasonic motors over the last decades. They have become promising precision driving components due to their unique piezoelectric transduction and friction drive mechanisms. This review summarizes the synthesis of the key technical aspects, research efforts, conclusions, and challenges that need to be highlighted concerning ultrasonic motor structural design and tribological performance. The analysis shows that the development of ultrasonic motor with new principles is in the ascendant. Simplifying the body structure, developing advanced friction contact models and life prediction models, developing new and environmentally friendly friction materials, and developing customized tribological testing devices are goals and tasks that should be considered in the future design of efficient ultrasonic motors.

“…The linear actuation of ultrasonic motors can be realized by the hybrid of two independent vibration modes, such as a bending and a longitudinal vibration modes [6][7][8][9][10], two bending vibration modes and two longitudinal modes [11][12][13][14]. The rotary actuation is usually realized by a traveling wave in a ring-type or cylinder-type stator and can also be realized by the hybrid of two vibration modes [15][16][17][18][19]. The multi-DOF ultrasonic motors need the ability of actuations in several directions.…”

A three-DOF ultrasonic motor is presented in this paper. The proposed motor consists of four piezoelectric ceramic plates and a mental base with a flange that can fix the motor on a rack. The proposed motor takes advantage of a longitudinal mode and two bending modes, different hybrids of which can realize three-DOF actuation. Because of symmetric structure of the proposed motor, the resonance frequencies of the two bending modes are identical. And the resonance frequency of the longitudinal mode was tuned closed to the ones of the bending modes by adjusting the structural parameters in modal analysis. Then trajectories of nodes on the driving foot were obtained by the transient analysis to verify the feasibility of driving principle. Experiments including vibration shape test and output characteristic test were executed. The starting voltages of the rotation along horizontal axes are about 10 Vp-p. Under driving voltages of 200 Vp-p, the output velocities of three DOF can reach 280 rpm, 277 rpm and 327 rpm, respectively. The results of the experiments indicate that the proposed motor is characterized by low starting voltages and high output velocities.
