Linear piezo actuator| 'XLA'

The benefits of piezo actuators, without the drawbacks

A piezo actuator that's not only small and precise, but also really fast, durable and noiseless? Meet our XLA.

Powered by our patented ultrasonic piezo motor, it offers the best of both worlds:

1) The size and precision of piezo
2) The speed, travel and lifetime of an electromagnetic motor

Note: The XLA will be available with an integrated closed-loop controller from January 2025.

Control types

Closed-loop version (with position feedback). External controller (XD-OEM) + integrated position sensor (= go to any position). Note: Internal closed-loop controller expected in November 2024. For ultimate compactness.

Open-loop version (without position feedback). Integrated controller, analog/PWM speed and direction control (and limit switches). Ultra-compact. A break-out board is available for testing.

Hybrid version: integrated controller + position feedback, but no closed-loop control. Close the loop in your own preferred way.

Ultrasonic piezo actuator | XLA

The Xeryon XLA is an ultrasonic piezo actuator. This miniature piezo actuator is very fast and precise, as well as noiseless.

It is powered by our patented ultrasonic piezo motor, which is very different from traditional piezo technologies such as stick-slip (inertia) or 'walking' piezo actuators. Our actuators offer the benefits of piezo (small, precise), but are also very fast, durable and noiseless. As a result of the much higher speeds, it is also possible to achieve larger travel ranges than typical piezo actuators.

The XLA piezo actuator is self-locking, meaning it holds its position when it is not powered. As a result, energy consumption and heat generation are considerably reduced.

The XLA is the fastest piezo actuator in the world.

Not small enough? We also design custom actuators for your specific product. Contact us to talk about a custom small actuator design.

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) The lifetime and speed of an electromagnetic motor.
2) The precision and compactness of a piezo motor.

Xeryon’s piezo 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 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-driveable, and free from drift or play.

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

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

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

No problem! There are several ways to achieve this with our piezo actuators:

1) Stacking multiple actuators

Xeryon's actuators are slim and stackable. Their cool operation allows them to be stacked against each other without overheating issues, and since there are no magnetic coils present, there is no risk of magnetic interference between the actuators.

2) Multiple motors on a single rod

Alternatively, multiple driving units can be combined on a single rod, doubling the driving force. Since this is not a standard product, it is best to contact our integration team about this.
