Piezoelectrical shaker for vibration excitation with frequencies up to 100 kHz from piezosystem jena

piezosystems Jena

The use of piezo shakers for vibration excitation has many advantages over conventional methods. Piezo shakers have a higher force potential as a result of their stiffness and their ability to operate at exceedingly higher frequencies. Due to their high power density they can be produced in compact sizes. These small elements can be used for modal analysis of mechanical structures. Massive piezo shakers with a seismic mass can modulate forces up to double-digit Kilonewtons.

Piezo shakers from piezosystems Jena are used in the following applications:

piezosystems jena: Long Travel Range Actuator PX 1500

csm Thumbnail PX 1500 c4766fa9c9

Piezoelectric actuators and stages are known for their precision in the nanometer and sub-nanometer regime. However, such accuracy comes with some compromise: Strokes are usually in the µm range. For most applications, this is not a problem. Often, µm-strokes are even explicitly required. Here, customers want to harness the high stiffness and resonant frequencies. The higher the stroke translation of the ceramic stacks via a solid state hinge system, the lower the stiffness, the resonant frequency and the resolution. The maximum load capacity decreases as well. For quasi-static applications on the other hand, customers sometimes require a higher stroke than what is usual for piezo systems. Here, the piezosystems jena PX 1500 comes into play.

piezosystems jena: NanoX technology enables high-speed piezo positioning

csm nanoX 200 72dpi 250x220mm d5daf890e4

Conventional piezo stages are usually designed in a way that the direction of motion of the piezo stacks is identical per axis. The forces generated by those stacks is then translated by solid state hinges. In dynamic operation however, this can cause the piezo stack to break if the generated pull forces exceed the internal preload. The motion of the actuator in the opposite direction of the stack motion is passive. A few years ago, piezosystem jena decided to tackle this challenge.

The result is the NanoX® design design, a completely new way of constructing a piezo stage. Here, piezo stacks are controlled opposed to each other. One stack is expanding while the other is contracting. Through this method an active backwards motion is achieved meaning even the backwards motion uses an actively expanding stack. This method of construction has several benefits for operational use. Not only is the stiffness increased, compared to stages with similar strokes, the stage can bear higher loads and generate higher forces.

Today, piezosystem jena offers many different models of the NanoX®. With the NanoSXY stages, there are even multi-axes systems available.

PSt actuators are some of the most versatile of the Piezocomposite line by piezosystem jena. These stack type actuators are being successfully used by many companies and research institution with applications requiring high force and/or highly dynamic actuation – they are applied as stabilizers, sensors or accelerators, among others. Often they are the go-to-solution thanks to their unique physical properties and compact construction design. The latter makes the PSt series especially flexible when it comes to the integration into existing applications and setups.

piezosystem jena: Ring Actuators R/RA

Ringaktor RA 72dpi 250x220mm 04 288ffaeac1

Ring actuators are often used in optical applications such as laser beam steering, fiber alignment or AFM scanning. In order to achieve optimal positioning results, these actuators have to fulfill a number of tough requirements. Especially stiffness and guidance accuracy are important criteria when it comes to operating the actuators in the sub-nm range and with high dynamics. The piezosystem jena ring actuator series R/RA was developed and designed by piezosystem jena to meet the high requirements of these applications.

The R/RA series ring actuators offers motion of up to 50 µm. Their apertures of up to 14 mm are especially useful for optical applications because they allow for light to travel through. Stiffness is up to 330 N/µm which enables the user to operate the actuators with extremely high dynamics. This is an especially beneficial characteristic for a ring actuator, since they are often used in laser resonators.

piezosystem jena: Piezo Micrometer Screw Drive

51b9b3ac05

Hybrid element that combines the advantages of long travel of micrometer screws, with the nm-accuracy of a piezo stage

These model MICI Piezo Micrometer Screw Drive elements from piezosystem jena were originally developed for quality control applications in the optics industry. They consist of a piezoelectric actuator in combination with a micrometer screw drive. The user can first adjust the coarse position of the actuator with a micrometer screw, and then fine tune it with the piezo stage itself. This improves the accuracy and reproducibility of the linear stage significantly.

Long travels up to tens of mm, depending on the used micrometer screw and sub-nm resolution can be reached while simultaneously moving high loads up to 20 kg with the MICI 80. This is due to its very robust construction.

So these piezo stages are perfectly suited for high precision adjustment of linear positioners. Based on its sophisticated solid state flexure hinge technology the MICI seriesoffers motion without mechanical play. Also these stages can be driven at high frequencies.

The MICI fits in applications like improvement of resolution of linear stages, quality control, automation, fine adjustment of optical components and micro-assembly. You have a choice of 4 models compatible with the micrometer drives of Mitutoyo, Newport or Qioptic.
