Miniature Linear Motors

You’re looking at a Xeryon mini linear motor driven by our Crossfixx™ ultrasonic piezo motor. Our micro motors offer the precision and size of piezo motors, without their typical drawbacks.

Our XLA is also commonly referred to as a miniature linear actuator or a linear piezo actuator.

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 a traditional electromagnetic linear motor.
2) The precision and compactness of a piezo motor.

Xeryon’s micro linear motors offer a unique combination of high speed, precision, long stroke, and durability in an ultra-compact design, overcoming the limitations of traditional linear motors such as its bulkiness, lack of holding force and complex thermal management.

Xeryon’s space-efficient linear motors are 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.

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