Authorised resellers of Hoerbiger piezoelectric actuators

For over 40 years HOERBIGER Motion Control GmbH has developed and produced piezo-ceramics and other piezo products in large volumes for a wide range of applications in a variety of markets, ranging from the aerospace to the automotive and medical industries. E.D.

E.D. Elettronica Dedicata is pleased to distribute HOERBIGER Motion Control GmbH piezo products for the circular knitting machine textile industry (seamless and large diameter hosiery and tights). (calze, collant, seamless e grandi diametri).

How a piezoelectric actuator works

Piezoelectric actuators are used in a variety of applications, from ultrasonic cleaning to precision positioning. They provide precise control and rapid response times, making them ideal for use in a wide range of industries. In this article, we will explore what a piezo actuator is, how it works and some of its unique applications.

Uses and applications of piezoelectric actuators in the textile industry

Piezoelectric actuators are used in a variety of applications, from ultrasonic cleaning to precision positioning. Flexible textile production is also based on piezoelectric technology, by selecting the needle electronically.

Piezoceramic-based needle selection systems are better than traditional magnetic or mechanical selection systems. The high selection speed of the actuators increases productivity, gives low energy consumption and reduces energy costs.

The reliability of the individual components also guarantees a long service life.

Purpose and operation of Hoerbiger’s piezoelectric actuators

The actuators can be supplied with two operating modes, either with integrated electronics using a standard BUS compatible with the WAC© system bus or without electronics for machines without many actuators installed.

A large variety of configurations are available to match the different machine models:

  • Single row or double row
  • From 6 to 8 or 16 levers
  • Various lever angles available
  • Standard or CNC levers for special shapes and different hardnesses
  • A variety of connectors: D-sub, flat or with pre-installed lead
  • Different ways of assembling the levers to suit different ways of attaching the actuator (top, bottom, right, left)

The following are standard for all actuators produced by HOERBIGER Motion Control GmbH:

  • Components are fully and rapidly replaceable, with no need for adjustments
  • Piezoceramics are made from powder mixtures monitored directly by HOERBIGER Motion Control GmbH for best performance and the highest quality
  • The ceramics and electronics are protected by a special coating against aggressive oils
  • 3-wire technology
  • Short, repeatable flight time of only 2.5 ms and movement in less than 4.4ms
  • Aluminium body milled from solid

The advantages of Hoerbiger piezoelectric actuators

Hoerbiger Motion Control GmbH is a brand well known for its reliability and long service life. With our experience and ability to produce high volumes of piezo-ceramic actuators, machinery and electronics we are able to offer the highest quality products at competitive prices.





The piezos are highly resistant to aggressive oils and high levels of humidity in the air.




The piezoelectric actuators produce no heat, which improves their service life in the long-term with no need for cooling.




Energy consumption is lower than with electromagnets, which gives lower operating costs and less stress on the electronics.



The high positioning speeds provide higher productivity, greater reliability and reduced downtimes.
