Micro Piezoelectric Ultrasonic Motors
This paper reviews recent developments of micro ultrasonic rotary motors using piezoelectric resonant vibrations. Following the historical background, four ultrasonic motors recently developed at Penn State University are introduced; windmill, PZT tube, metal tube, and shear-type motors. Driving principles and motor characteristics are described in comparison with the conventional ultrasonic mo...
متن کاملPiezoelectric ultrasonic micro/milli-scale actuators
A growing demand for actuators with a volume of less than 1 mm3 has driven researchers to produce a varied range of micro/milli-scale designs. By examining the underlying physics of the actuator operation we are able to demonstrate why piezoelectric ultrasonic actuators have the greatest potential to meet this need. Moreover, it allows us to create a new classification system for piezoelectric ...
متن کاملAn Introduction to Ultrasonic Piezoelectric Motors
This paper introduces the piezoelectric ultrasonic motors, the historical context of their development and current trends of research and development.
متن کاملComputer-Aided Design and Optimization of Piezoelectric Ultrasonic Motors
Piezoelectric ultrasonic motors are superior to electromagnetic micro motors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potential. Numerical structural analysis by the means of the finite element method (FEM) is a common approach for dimensioning piezoelectric motors...
متن کاملA High Power Piezoelectric Ultrasonic Linear Micromotor Using Slotted Stator
A novel ultrasonic micro linear motor that uses 1st longitudinal and 2nd bending modes, derived from bar type stator with a rectangular slot cut through the stator length, has been proposed and designed for end-effect devices of microrobotics and bio-medical applications. The slot structure plays an important role in the motor design, and can be used not only to tune the resonance frequency of ...
