  • Ultrasonic Motor Utilizing a Wave Spring
    Ultrasonic motors are small motors, some measured in millimeters, often used in the auto focus feature on modern DSLR camera lenses. Other applications are usually seen in the automotive industry in headrests or side mirrors, surgical equipment and now common in robotics movement. What made
  • Maple Used to Help Develop Model of Ultrasonic Motor for Controller Design
    A leading provider of consumer and professional digital imaging solutions required an accurate, fast-performing model of an ultrasonic motor (USM) for use in its line of cameras. Widely used in the field of mechatronics, USMs present unique modeling challenges. The phenomena created by the USM
  • Reliability of Ultrasonic Motors
    This white paper is intended to provide a better understanding of what this wear is and what it means in terms of product lifetime. Furthermore, it focuses on showing why and under which circumstances neither lifetime nor general reliability is an issue when using PILine (R) motors.
  • Positioning Capabilities of Ultrasonic Motors
    While conventional positioning systems convert the rotary motion of a motor into linear motion using a spindle, PILine (R) positioning systems are based on a special direct drive. This completely eliminates backlash and play and enhances the response time and positioning accuracy. Furthermore
  • USM (Ultrasonic Motor) Features
    USM is the piezoelectric actuator and has the following features.
  • Overview of Different Piezo Motor Design Principles
    rotary or linear motions. Methods of obtaining long moving distance. have various drive and functional principles that make these motors categorized into three groups: resonance-drive (piezoelectric ultrasonic motors), inertia-drive, and piezo-walk-drive. In this review,. a comprehensive summary
  • Effects of Ultrasonics on Health
    energy is the ultrasonic transducer: a linear motor that converts electrical energy to reciprocating mechanical motion similar to a high-speed hammer. The motion occurs at a rate of 20,000 strokes or more per second, and is above the hearing range of the average person. The ultrasonic mechanical
  • Using Infrared and Ultrasonic Technology in a Predictive Maintenance Program
    implemented an ultrasonic bearing testing program to supplement infrared data and images, proving to the customer that testing for motor bearing failure is very worthwhile, and that, once again, the infrared pictures don't lie. Infrared is used to determine overall motor condition, and ultrasonic testing
  • Piezo Motors: Principle of Operation for Engineers
    How it Works. The Piezoelectric effect in piezoceramics converts electrical field to mechanical strain. Under special electrical excitation drive and ceramic geometry of Nanomotion motors, longitudinal extension and transverse bending oscillation modes are excited at close frequency proximity
  • Piezo Transducers, Actuators, and Motor Drive Solutions for Medical Engineering
    Medical engineering and life-science disciplines have multi-faceted requirements for motion and positioning equipment: the spectrum spans from ultrasonic transducers to simple low-energy drive components to high-precision positioning systems and ultra-fast actuators for valve and pumping
