ultrasonic motor

You can focus very quickly and silently, thanks to its UltraSonic motor ring.

Ultrasonic motors replace the noisier and often slower micro-motor in this application.

Ultrasonic motor - linear motor with iron mass on its edge to get accurate impact.

It features an ultrasonic motor.

One common application of ultrasonic motors is in camera lenses where they are used to move lens elements as part of the auto-focus system.

Recent alternatives to DC motors are piezo motors or ultrasonic motors.

Many modern cameras now use automatic focusing mechanisms which use ultrasonic motors to move internal elements in the lens to achieve optimum focus.

With ring USM (ultrasonic motor)-powered rear focus, autofocusing is silent and fast.

Dynamic lift was boosted 30% by the introduction of more powerful ultra-thin ultrasonic motors and newly designed, optimally shaped main rotors.

Ring-type USM (ultrasonic motor) and full-time manual focusing.

The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors.

The friction modulation allows bulk motion of the rotor (i.e., for farther than one vibration cycle); without this modulation, ultrasonic motors would fail to operate.

Uses a "Silent Wave Motor" (SWM) (ultrasonic motor) to focus quietly and quickly.

The lens features weather sealing, an SDM ultrasonic motor for quiet autofocus, and has 9 rounded diaphragm blades for smoother bokeh.

A range of high-precision Ultrasonic Motor (USM) EF autofocus lenses were also developed successfully for the 650.

Ultrasonic motors also offer arbitrarily large rotation or sliding distances, while piezoelectric actuators are limited by the static strain that may be induced in the piezoelectric element.

SSM - "SuperSonic Motor", in-lens ultrasonic motor used on some long telephoto G Series lenses.

A key observation in the study of ultrasonic motors is that the peak vibration that may be induced in structures occurs at a relatively constant vibration velocity regardless of frequency.

Ultrasonic motors differ from piezoelectric actuators in several ways, though both typically use some form of piezoelectric material, most often lead zirconate titanate and occasionally lithium niobate or other single-crystal materials.

An ultrasonic hammer (the same ultrasonic probe that use in ultrasonic welding), that consist a linear ultrasonic motor terminated by iron mass, create an impact on the device under test.

The camera, with the new SWD (ultrasonic motor) lenses, is expected to appeal to professional users who want a rugged, portable and lightweight camera body with quality lenses and class leading autofocus.

The FR is levitated by contra-rotating propellers powered by four 7x2x1-mm ultrasonic motors (originally developed for wristwatches) and is balanced in mid-air by means of a stabilizing mechanism that uses a linear actuator.

The technology, adapted to include a scanning capability (to provide measurement of the vibration over an array of points), has been used to measure vibration generation and propagation for ultrasonic motors and acoustic and ultrasonic microfluidics.

An ultrasonic motor is a type of electric 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).

An exceptionally high-torque 'hybrid transducer' ultrasonic motor uses circumferentially-poled and axially-poled piezoelectric elements together to combine axial and torsional vibration along the contact interface, representing a driving technique that lies somewhere between the standing and traveling-wave driving methods.
