A 40V monolithic ultrasonic motor driver
2017 IEEE 12th International Conference on ASIC (ASICON), 2017Miniaturizing the driving circuit of ultrasonic motor (USM) is very important to apply the miniaturized USM. Based on a 0.35μm BCD process, this paper designs a novel 40V monolithic USM driver chip, which includes a boost converter sub-circuit and an H bridge sub-circuit. The peak current mode boost converter provides power supply for the H bridge. And

Great research progress for step USMs has been achieved since their invention more than 10 years ago. In 1991, Kusakabe developed a standing wave and self-correction USM[1], which made the USM succeed in step motion without feedback. Later, Miyazawa put forward a step USM[2]–[3] using a shifting standing wave mode based on Iijima’s standing wave USM in

This thesis is treating theory, modeling, model analysis and experiments of traveling wave type ultrasonic motors. A framework to derive models for ultrasonic motors is given here, which is based on the continuum theory of electromechanical solids. This includes the modeling of the stator-rotor contact and the electromechanical behavior of piezoceramic

Practical considerations in ultrasonic motor selection
Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010This article shows that using a piezoelectric motor in a mecatronic system, the thermal management is not an issue, as for conventional electromagnetic motors. We then show that choosing a motor on the maximal velocity or force/torque required in the application is not sufficient, and the motor selected may not be able to perform the motion profile. We

As a type of ultrasonic motors, a linear ultrasonic motor (LUSM) also utilizes the converse piezoelectric effect of piezoelectric ceramics and the ultrasonic vibration of an elastic body [1]. It transfers the micro amplitude motion of a stator into the macro linear motion of a slider by the friction force between the stator and slider.
