“…In Table 2, some proposed motors which can realize rotary and linear motions are compared with the prototype motor in terms of the working principle, the main size when removing the output shaft, the peak-to-peak driving voltage, the maximum rotary velocity, the output torque, the maximum linear velocity, and the output force. Table 2 shows that the prototype motor has higher velocity compared to the inchworm actuator which is proposed by Sun [13] and the load capacity is stronger than the ultrasonic actuator which is proposed by Mashimo [14]. The speed of motion of the prototype motor is similar to the impact motor which is proposed by Zhang [12].…”

“…The motor which consists of two or more actuators can realize rotary and linear motion [10,11]. This kind of motor can realize independent rotary and linear motion, and the two motions usually cannot move at the same time [12,13]. The ultrasonic motor which uses the two specific vibration modes can realize a coupled rotary-linear or screw-type motion [14][15][16].…”

A novel impact two-degree-of-freedom (2-DOF) motor based on the decomposed screw-type motion of a piezoelectric actuator (PA) has been proposed. The fabricated prototype motor has a maximum diameter of 15 mm and a length of 100 mm which can produce a maximum torsional angle of about 1000 μrad and a maximum longitudinal displacement of about 1.03 μm under a saw-shaped driving voltage with 720 Vp-p (peak-to-peak driving voltage). When the axial prepressure generated by the spring is about 1N and the radial prepressure generated by the snap ring is about 14 N, the fabricated motor realizes rotary motion with the driving frequency from 200 Hz to 4 kHz. When the axial prepressure generated by the spring is about 11.7 N and the radial prepressure generated by the snap ring is about 21.1 N, the fabricated motor realizes linear motion with the driving frequency from 2 kHz to 11 kHz. In the experiments, the prototype motor can achieve 9.9 × 105 μrad/s rotary velocity at 2 kHz and it can achieve 2.4 mm/s linear velocity at 11 kHz under the driving voltage of 720 Vp-p.

“…Multi-DOF motions of PIDM can be designed in two structures. The first kind of structure is the complex structure in series [3][4][5], for which the motions are independent and their corresponding controls are relatively simple. The second kind of structure is the compact structure in parallel [6][7][8][9], for which the motions often share a common friction interface [6,8] that leads to a coupled motion when the motions are operated at the same time [8,10].…”

Recent studies on parallel PIDMs have attained multi-DOF motions by using different modes of vibration under ultrasonic driving [8,[11][12][13][14][15], and studies on series PIDMs have achieved multi-DOF motions by avoiding coupled motions [4,5,16]. However, there are few studies on the coupled motion characteristics of the parallel impact PIDM [17,18].…”

A two-degrees-of-freedom (2-DOF) linear piezoelectric impact drive mechanism (PIDM) is actuated by two independent piezoelectric actuators (PAs). The coupled motion interactions of a two orthogonal DOF linear PIDM with a single friction interface are introduced and analyzed. A complete dynamic model of the 2-DOF PIDM is established with the Karnopp friction model considering the distribution of friction in the x-axis and y-axis. The output displacements of the 2-DOF PIDM and two corresponding independent 1-DOF PIDMs are investigated numerically. When the two input exciting signals of a 2-DOF PIDM have the same driving voltage of 100 V with a duty ratio of 98% at 10 Hz and two 1-DOF PIDMs are driving under the same conditions, the step displacements in the two axes of 2-DOF PIDM are improved compared to the corresponding 1-DOF PIDM. When the two input exciting signals of a 2-DOF PIDM have the same driving voltages of 100 V with a duty ratio of 98% but the driving frequency is 10 Hz in the x-axis and 20 Hz in the y-axis, the results show that the displacement of high frequency achieves a slight decrease and displacement of low frequency shows a large increase compared to the two corresponding 1-DOF PIDMs.

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.
