Achieves stable rotation performance, strong holding power, and high quietness!
Ultrasonic motors utilize the deformation of piezoelectric ceramics when a voltage is applied to them to achieve rotation. They are named "ultrasonic" motors because the frequency of that voltage exceeds the audible range for humans (below 20 kHz). Since then, the USR series of ultrasonic motors developed by Shinsei Industry has undergone continuous improvements aimed at enhancing functionality and reliability. The culmination of this technology is represented by the USR30 series with a diameter of 30 mm and the USR60 series with a diameter of 60 mm. As a result of these efforts, the USR series has been adopted by many companies and academic institutions around the world, earning a high reputation as the de facto standard for ultrasonic motors. Currently, both the USR30 series and USR60 series are manufactured and sold as standard motors intended for use in general environments, as well as non-magnetic motors designed for use in high magnetic field environments.

Company information
Our company, Shinsei Kogyo Co., Ltd., was the first in the world to put ultrasonic motors into practical use, commercializing them in 1986. Since then, we have continuously improved ultrasonic motors, aiming to enhance their functionality and reliability. The culmination of that technology is the USR series (USR30 and USR60 series). The USR series features compact size, low speed, high torque, and high holding power when not powered, making it ideal for actuators. With high responsiveness and very low operating noise, ultrasonic motors are widely used in applications such as camera autofocus and lifting mechanisms in measuring instruments. In recent years, our non-magnetic ultrasonic motors have gained significant attention as motors that can be used within MRI machines, serving as embedded actuators for medical devices.
