“…The continuous development of precision control technology puts forward higher requirements for the operating characteristics and environmental adaptability of the motor, which is particularly prominent in space satellite exploration and high-pressure deep sea [1][2][3]. The deficiencies of traditional electromagnetic motors, such as complex shape, high energy consumption and easy to be influenced by environmental factors have gradually restricted their application [4].…”

Traditional mode conversion ultrasonic motors are typically composed of the superposition of multiple vibration modes, making them more complex than single-mode ultrasonic motors. This complexity makes it difficult to miniaturize. A micro radial-torsional vibration mode ultrasonic motor is proposed and tested in this work. It is excited by a single-phase excitation signal. The proposed motor utilizes the radial inplane vibration mode of the stator to convert the torsional vibration mode of the inner ring through the beams. The torsional vibration of the inner ring causes the rotor to rotate due to the friction force between the inner ring and the rotor. Based on the designed structure and verified using the finite element method, a prototype motor with a mass of 2.6 g and overall dimensions of Ф20 mm in diameter and 15 mm in height is fabricated and characterized. During the mechanical output performance test, the prototype achieved a maximum noload speed of 3300 r/min and a stall torque of 0.2 mN• m at the driving voltage of 100 Vp-p.INDEX TERMS Ultrasonic motor, piezoelectric actuator, radial-torsional vibration, mode conversion.

“…The piezoelectric actuator can achieve direct drive, fast response, and miniaturization [31][32][33][34]. At the same time, because the drive interface allows water to enter, the open structure design can be adopted without the need for complex water pressure balance and waterproof sealing treatment [35,36]. At present, there have some researches using piezoelectric actuators in underwater environments.…”

For some underwater applications that need lightweight manipulator and fine operation, a novel piezoelectric actuated underwater mechanical manipulator two-degrees-of-freedom (2-DoF) joint was proposed and investigated in this study. The joint is composed of two unit arm sections orthogonally connected by connecting components. The inverse piezoelectric effect of the piezoelectric actuator on the unit arm section generates friction as a driving force in the contact area of the two unit arm sections, which can realize the 2-DoF rotation of the unit arm section. Due to the compatibility of the piezoelectric actuated method with the water environment, the manipulator joint adopts a simpler and more compact open structure, which does not require additional complicated waterproof sealing devices, and has the advantages of smaller size and lightweight. In addition, because the piezoelectric actuated method directly drives the unit arm section through the friction contact interface, it can achieve micro-displacement, so that the joint has the advantage of fine work. First of all, a 2-DoF joint prototype was designed, and corresponding simulations were performed to verify its working principle. Then a prototype of the proposed manipulator joint was made, its size is 125 mm × 25 mm × 25 mm and weighs 35.6 g, and experimental investigation was carried out. Finally, the experimental results show that the joint prototype can achieve motion in the air and underwater. The water environment will have a certain influence on the optimal working frequency and output performance of the joint. The proposed joint has potential application prospects in some microminiaturization and fine manipulation occasions.
