Silent Linear Actuator

XLA Series: A Breakthrough in Motion Control

For decades, linear actuators have seen little true innovation.

Traditional piezo motors offer miniature size and precision, but lack speed, travel and durability.

Electromagnetic motors, on the other hand, are often too bulky and require constant power to hold position.

Many existing technologies have reached their physical limits, blocking engineers from making the next big leap forward.

The Xeryon XLA is the answer to this problem.

A silent linear actuator designed for the next generations of instruments.

Now available with integrated controller, for ultimate compactness.

Advanced ultrasonic piezo technology

Through our ultrasonic piezo technology, our XLA miniature linear actuators operate at frequencies above 100 kHz. This means they work beyond the human hearing limit, ensuring their operation is virtually noiseless. Unlike traditional actuators that create audible noise, our quiet linear actuators provide a silent solution, essential in settings where noise is a concern.

Compact, efficient, and precise

But that’s of course not all. Despite their small size, these actuators are powerful and precise. The XLA is capable of high-speed movement (up to 500 mm/s) and micrometer positioning, essential for applications requiring fine control. Their compact design also makes them suitable for use in confined spaces where traditional actuators might not fit. Lastly, with a lifetime of over 1000 kilometers or 20 million cycles, they far outlast most (if not all) other types of linear actuators.

Much lower noise levels compared to conventional actuators

When compared to other types of micro linear actuators, our ultrasonic piezo actuators stand out for their significantly lower noise levels. Conventional actuators, which often use electromagnetic motors and mechanical gears, typically operate within the audible range and can be a source of disruptive noise. Due to their lower frequencies, these actuators also pose the risk of sending vibrations into the surrounding mechanical systems.

Our XLA ultrasonic actuators provide a quiet alternative, eliminating the sound issue and enhancing the overall user experience.

Technical details

Ideal applications for quiet linear actuators

Our silent linear actuators are particularly suited for:

Medical equipment: In medical settings, the quiet operation minimizes disturbance to patients and staff.
Laboratory instruments: For lab equipment, the absence of noise helps maintain a controlled environment for sensitive experiments.
Industrial automation: In industrial settings, they reduce overall noise pollution, creating a more comfortable working environment.

These compact actuators represent a significant advancement in motion control technology. By offering a noise-free operation, they open up new possibilities in various fields where traditional piezo actuators' noise levels were previously a limiting factor.

How it works

Recently, Youtuber 'Know Art' visited Xeryon in his search to better understand precision mechanics.
The result? A deep dive into high-precision motion, and a great breakdown of our revolutionary technology:

Made in Europe. Trusted globally.

+ Over 500 NDA's

The speed and precision of Xeryon’s products enabled us to significantly improve our microscope design and disrupt the market. Most importantly, it has allowed our customers to accelerate scientific discovery. It’s rare to achieve such a technological leap.

Fluorescence microscope manufacturer

Our laser systems use a large number of motorized optics. After experiencing quality and delivery issues with our main supplier, we decided to give Xeryon a try. They have proven to be a reliable supplier, and we found their piezo stages to be much more durable than the ones we used before.

At first, I found it hard to believe this level of performance could come from such a compact package. Xeryon’s technology was the only solution that made it possible to build the machine our company had envisioned, enabling the next generation of automated test equipment. Their team was also incredibly helpful in answering all of our integration questions.

Frequently asked questions

Our Crossfixx™ ultrasonic motor uses vibration to move a ceramic tip in an elliptical pattern at a very high frequency (80 kHz - 180 kHz). Spring-loaded against a ceramic strip on the actuator rod, it generates very small but rapid movements, resulting in high-speed motion and silent operation with a long lifetime.

This gives you the best of both worlds:

1) Lifetime and speed comparable to a direct-drive electromagnetic motor.
2) The precision and compactness of a piezo motor.

Xeryon’s silent linear actuators offer a unique combination of high speed, precision, long stroke, and durability in an ultra-compact design, overcoming the limitations of traditional linear actuators where trade-offs have to be made (e.g. stroke length in voice coils, speed in screw-driven actuators & size and holding force in linear motors).

Xeryon’s actuators are gearless, self-locking, energy-efficient and operate at low voltages. They don’t produce a magnetic field, are back-drivable, and free from drift or play.

For a complete overview of different micro linear actuators, take a look this page.

Xeryon’s silent linear actuators are much faster, have a much larger stroke, a much (much!) longer lifetime, operate noiselessly, consume less power, and operate at a much lower voltage at the piezo element.

In other words, they offer the precision and size of traditional piezo actuators, without their typical drawbacks.

Traditional stick-slip piezo actuators operate at much lower frequencies, typically within the frequency range of small mechanical components. Apart from being in the human audible spectrum, this introduces the risk of the piezo motor making the entire system vibrate, rather than only the motor itself.

Xeryon's silent linear actuators operate at much higher frequencies (80 - 180 kHz), ensuring silent operation and no unwanted vibrations.
