“…Zhang et al, proposed a solution to reduce the radial sliding by optimizing the stator comb-teeth of a TRUM [50]. They further developed a 3D finite element model for longitudinal torsional USM by ADINA in order to study the mechanical simulation and contact analyses [51]. A novel hollow type USM, which the preload was applied from the bottom of the stator through a wave spring, was proposed, [52] It could not only enhance the anti-overload ability but also extended the working life of the motor.…”

Piezoelectric Ultrasonic motors (USM) are based on the principle of converse piezoelectric effect i.e., vibrations occur when an electrical field is applied to piezoelectric materials. USMs have been studied several decades for their advantages over traditional electromagnetic motors. Despite having many advantages, they have several challenges too. Recently many researchers have started focusing on Industry 4.0 or Fourth Industrial revolution phase of the industry which mostly emphasis on digitization & interconnection of the entities throughout the life cycle of the product in an industrial network to get the best possible output. Industry 4.0 utilizes various advanced tools for carrying out the nexus between the entities & bringing up them on digital platform. The studies of the role of USMs in Industry 4.0 scenario has never been done till now & this article fills that gap by analyzing the piezoelectric ultrasonic motors in depth & breadth in the background of Industry 4.0. This article delivers the novel working principle, illustrates examples for effective utilization of USMs, so that it can buttress the growth of Industry 4.0 Era & on the other hand it also analyses the key Industry 4.0 enabling technologies to improve the performance of the USMs.

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.

“…Bathe (2006), the founder of ADINA R&D Inc., a target-contactor approach with a proper Coulomb friction coefficient is adopted. The Coulomb friction coefficient used Ren et al (2019) and Yang et al (2020) is 0.3 but actually it is a static friction coefficient instead of the dynamic friction coefficient, which may account for the model’s calculation error. Different from the traditional friction pair, this motor adopts a friction pair composed of stainless steel and a new friction material (mainly based on PTFE).…”

A novel hollow type of traveling wave rotary ultrasonic motor is proposed, optimized, fabricated, and tested in this study. Unlike conventional ultrasonic motors, this novel ultrasonic motor adopts a bran-new preloading method that preload is applied from the bottom of the stator through a wave spring, which can not only enhance the anti-overload ability but also extend the working life of the motor. According to this motor, a three-dimensional finite element model has been built by the commercial finite element software ADINA. In terms of the friction material and the preload, a detailed further optimization procedure is given after the initial design. Finally, the appropriate size and location of the friction layer and a proper preload for this motor have been determined. Almost all of the motor’s mechanical capacities, such as rotational speed, torque, and deformation, can be obtained by simulations in ADINA, which have good agreement with experimental results.
