Hybrid Transducer Type Ultrasonic Linear Motor
Japanese Journal of Applied Physics, 1989Hybrid transducer type ultrasonic motors have the advantage of freedom of design. A linear motor of this type consists of a longitudinal vibrator and multilayered piezoelectric actuators. The transducer is operated at the resonance frequency of the vibrator. In this paper, the characteristics are measured in a study of the basic operating conditions,

Design and driving characteristics of ultrasonic linear motor
Ferroelectrics, 2001Abstract This paper gives results on theoretical and experimental studies about an ultrasonic linear motor using a combination of the first longitudinal and the fourth bending mode. Four pairs of stacked PZT ceramic plates were bonded both on and bottom sides of a straight aluminum bar as driving elements.

The research of the clamping effect on the linear ultrasonic motors
2013 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications, 2013The flexible hinge has been proved to be more suitable for the clamping design than the spring. But, it still lacks in-depth research on how the flexible hinge affects the motor's output. In this paper, the laser interferometer is used to measure the real-time displacement of the slide, from which the speed and acceleration curves can be compared to ...

Driving concepts for bundled ultrasonic linear motors
Journal of Electroceramics, 2007Several positioning tasks demand translatory drive instead of rotary motion. To achieve drives that are capable, e.g., to drive the sunroof of a car or to lift a car’s window, multiple miniaturized motors can be combined. But in this case many other questions arise: The electromechanical behavior of the individual motors differs slightly, the motor ...

Design and evaluation of a micro linear ultrasonic motor
Sensors and Actuators A: Physical, 2018Abstract We propose a micro linear ultrasonic motor, which is one of the smallest linear actuators that can generate practical force. Such a small actuation mechanism can be used for a wide range of applications, such as auto-focus systems used in thinner cell phones and smaller endoscopes.

Ultrasonic Linear Motor with Two Independent Vibrations
Japanese Journal of Applied Physics, 2004We propose a new structure of an ultrasonic linear motor in order to solve the problems of high-power ultrasonic linear motors that drive the X Y-stage for electron beam equipment and to expand the application fields of the motor.

Research of a Ring-Type Linear Ultrasonic Motor
Advanced Materials Research, 2011A new ring-type linear ultrasonic motor is proposed in this study. In this new design, bending vibration traveling wave is generated in a long ring by two groups of PZT ceramics bonded on the inner sides of the linear beams. Elliptical trajectory motions can be formed at particles on the teeth, which can realize the linear driving by frictional force ...
