Linear piezo actuator | XLA

The Xeryon ultrasonic mini linear actuator is a precise and very fast linear piezo actuator driven by our noiseless Crossfixx ultrasonic motor. This allows for high speed motion and precise positioning.

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

The XLA is the fastest actuator of such a small size in the world. It is a real OEM product but a break-out board is available for test setups.

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

Control types

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.

Closed-loop version (with position feedback). External controller (XD-OEM) + integrated position sensor (= go to any position).

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

Frequently asked questions

Our Crossfixx™ ultrasonic piezo 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 micro 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 and size factor 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.
