Ultrasonic Vibration Motor

An ultrasonic motor is a type of piezoelectric motor powered by the ultrasonic vibration of a component, the stator, placed against another component, the rotor or slider depending on the scheme of operation (rotation or linear translation). Ultrasonic motors differ from other piezoelectric motors in several ways, though both typically use some form of piezoelectric material, The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors.

Ultrasonic motor (USM) is an actuator that converts characteristic vibration (resonance) of several μm in amplitude generated in the metallic elastic body (transducer, stator) into rotation or translational movement of motive elements (rotor, slider) with friction. It was invented by Mr. Toshiiku Sashida in 1980. Ultrasonic motors (USMs) use the inverse piezoelectric effect of piezoelectric elements to excite micro-vibrations of the stator. The key advantages of USMs over conventional electromagnetic motors are compactness, quick response, and no electromagnetic interference (Yang et al., 2009; He et al., 2011; Al-Budairi et al., 2013).

1. Introduction. A linear ultrasonic motor (LUSM) is an electromechanical device that transfers ultrasonic vibration with amplitude of the order of micrometers into unidirectional motion through friction coupling [1,2,3].Since the ultrasonic vibration of LUSMs are excited by the inverse piezoelectric effect of piezoelectric ceramics, they feature fast response, high resolution, long stroke.

An ultrasonic motor is a piezoelectric device which produces rotary or linear motion from ultrasonic vibrations via friction. Ultrasonic motors produce a much larger torque/force than conventional electromagnetic motors. Several basic principles are introduced for rotary and linear motors. Two orthogonal vibration components are essential for.

Ultrasonic motors are so physically flexible that a very thin motor or a liner motor can be realized easily. A recently-developed product is a ring motor which drives interchangeable lenses on a single-lens reflex camera or a mirror-less camera. Auto-focus is done by rotating the lens, and the rotation is brought by the ultrasonic ring motor.

Omegasonics understands the pressure our clients are under to reduce rising labor costs, eliminate dangerous solvents in the workplace, and deliver the cleanest parts available. We have the largest selection of ultrasonic cleaners available to give you more options. And if you don't see exactly what you want, we will build you a custom washer.

Ultrasonic cleaners work by creating small bubbles that appear and collapse over and over again. This process is called cavitation. Since the bubbles are what are doing the cleaning, the solder joints are safe. A chemical used during soldering, called flux, is cleaned off of motherboards by ultrasonics at their manufacturers.
