A high-power ultrasonic transducer for minimally invasive treatments is proposed, capable of treating areas inaccessible by high-intensity focused ultrasound treatments. This transducer employs two elliptical reflectors that efficiently focus ultraso

Speed control of ultrasonic motors (USM) needs to be precise, fast, and robust; however, this becomes a challenging task due to the nonlinear behavior of these motors including nonlinear response, pull-out phenomenon, and speed hysteresis. However, l

In this study, we aimed to improve the backdrivability and torque control of a traveling wave ultrasonic motor (TWUSM). Because of its operating principle, a TWUSM has strong holding torque. While this feature is useful for maintaining the rotor in a
