“…A type of rotary single-phase driven ultrasonic motors for watches and micro fans was proposed in (Aoyagi et al, 2004; Miyazawa et al, 1999). This type of resonator used the first-order longitudinal mode of a rectangular plate, and the size of which was miniature and the performances of which were good; however, this type of ultrasonic motor cannot rotate in the opposite direction.…”

In recent decades, various single-phase drive ultrasonic motors have emerged, and only a single excitation signal is used in their working states. Single-phase driven ultrasonic motors have the benefits of most ultrasonic motors, as well as the advantages of a simple driving circuit construction, low cost, high design flexibility, and high reliability, among others. According to the working principles, they are divided into three types: the vibration mode alternating type, the vibration mode coupling type, the vibration mode converting type. This paper summarizes various types of single-phase ultrasonic motors. The three types of the working principles and its representative structures are explained; output performances of the single-phase ultrasonic motors are described; then, practical and potential applications of the single-phase ultrasonic motors are introduced; finally, the research of single-phase ultrasonic motors are reviewed, and its development prospect is prospected. This review is helpful for a comprehensive understanding of single-phase drive ultrasonic motors. This paper offers the groundwork for the development of a novel single-phase driven ultrasonic motor with improved mechanical output.

“…The vibration mode for the ultrasonic motor was the first longitudinal in-plane vibration mode. The vibration direction of the driving foot at each end was opposite to each other [27,28]. The longitudinal vibration of the metal plate caused the driving foot to have a linear motion along the surface of the shaft and to push the shaft to rotate in one direction.…”

Micro underwater vehicles (MUVs) have been highlighted recently for underwater explorations because of their high maneuverability, low price, great flexibility, etc. The thrusters of most conventional MUVs are driven by electromagnetic motors, which need big mechanical transmission parts and are prone to being interrupted by the variance of ambient electromagnetic fields. In this paper, a novel dual-rotor ultrasonic motor with double output shafts, compact size, and no electromagnetic interference is presented, characterized, and applied for actuating underwater robots. This motor was composed of a spindle-shaped stator, pre-pressure modulation unit, and dual rotors, which can output two simultaneous rotations to increase the propulsion force of the MUV. The pre-pressure modulation unit utilized a torsion spring to adjust the preload at the contact faces between the stator and rotor. The working principle of the ultrasonic motor was developed and the vibration mode of the stator was analyzed by the finite element method. Experimental results show that the no-load rotary speed and stalling torque of the prototype ultrasonic motor were 110 r/min and 3 mN·m, respectively, with 150 V peak-to-peak driving voltage at resonance. One underwater robot model equipped with the proposed ultrasonic motor-powered thruster could move at 33 mm/s immersed in water. The dual-rotor ultrasonic motor proposed here provides another alternative for driving MUVs and is appropriate for developing specific MUVs when the electromagnetic interference issue needs to be considered.

The aim of this paper is to design a new low-profile micro ultrasonic motor which can be used in high magnetic field. In advanced scientific and industrial fields, the demand for instruments that use high magnetic fields has increased. We have fabricated a micro motor for sample spinning in high-resolution solid-state nuclear magnetic resonance (NMR) system. To avoid the influence against the measurement of NMR system, the low-profile ultrasonic motor has been designed and fabricated. We have evaluated its driving performance in a magnetic field of 7 T. The result shows that the micro motor can be used for the sample spinning in high magnetic field.
