Product Overview

Product Introduction

S34.T2S/KY Piezo Tip/Tilt Platform has the following advantages:

High performance piezo stack:
- S34.T2S/KY Piezo Tip/Tilt Platform is driven by a highly reliable ceramic actuator with a fully insulated structure, so its performance and service life are far better than the traditional actuator. The insulating layer can effectively prevent the piezoelectric ceramic from being damaged when exposed to moisture. Therefore, the stability of piezoelectric ceramics can be guaranteed under extreme circumstances. Compared with traditional driving mechanism, there are no transmission parts and friction. Therefore, ceramic actuator has the characteristics of no rebound, no maintenance, and no wear, etc.
Flexible hinge structure:
- S34.T2S/KY Piezo Tip/Tilt Platform adopting flexible hinge mechanism has advantages of no friction, high positioning accuracy. Flexible hinge is an element not affected by static and dynamic friction, based on the elastic deformation of metal material (e.g., steel) , there is no rolling and sliding parts. Flexible unit has very high load capacity and stiffness. Hinge guide needs no maintenance and no wear and tear. Suitable for a wide range of temperatures, no lubricating oil is required.
Strain sensor
- Strain sensor detects the position information by its own expansion. They are fixed in the proper position of the transmission part and measure the displacement of the moving part. This type of position measurement is made by contact and indirect measurement. So the displacement of the moving platform is measured by measuring lever, guide hinge, or piezoelectric ceramic stack.
  S34.T2S/KY Piezo Tip/Tilt Platform is a deflection platform withfast response and compact size. It provides high-precision angular motion of the top platform. Compared with other actuators, the flexible hinge-guided piezoelectric deflection platform provides higher acceleration.

Principle

The piezo control principle is as follows:

Piezo tilt stage(two-axis motion) is based on parallel kinematic design with coplanar axis and moving platform. Four piezo actuators are placed at a 90° angle interval, paired differential control distribution. Two pairs of differentially driven actuators provide the highest achievable angular stability over a wide temperature range. Its tilt motion is achieved by two pairs of piezo actuators in a push-pull motion, controlled by a bridge connection circuit.

The deflection angle can be calculated as follows The tilt angle in θx:

Wherein:

Similarly, the tilt angle in θy:

Dynamic characteristics of S34.T2S/KY Tip/Tilt Platform:
Operating frequency of S34.T2S/KY depends on its resonant frequency. In order to estimate its resonant frequency after loading mirror (moving surface and mirror), the moment of inertia of mirror must be taken into account.
The moment of inertia of mirror is calculated as follows: the moment of inertia of a cylindrical mirror:

The moment of inertia of a rectangular mirror:

Wherein:

m – Quality of mirror
– The moment of inertia of mirror
L – Length of the mirror perpendicular to the rotation axis
H – Thickness of mirror
T – Distance between the axis of rotation and the surface of the platform
R – Radius of mirror

The resonant frequency of after loading mirror can be calculated by using unloaded resonant frequency and the moment of inertia of mirror. The calculation formula is as follows:

Wherein:

– Resonant frequency
– The moment of inertia of unloaded moving surface
– Unloaded operating Frequency
– The moment of inertia of mirror

Relative humidity: <60%
Recommended voltage between 0 and 120V for long-term and high-reliability operation

Installation and operation

Before installation, first check the safety, such as whether the cable is damaged or broken, and whether the power supply has grounding protection.

Installation and connection

S34.T2S/KY installation diagram is as follows:

Before attach the mirror, please clean the mirror and motion surface. After the mirror is glued, please wait for a period of time until adhesive solidify.
You need to use M4 screws to mount the S34.T2S/KY, and you also can adopt a adapter, and we have many adapters for your choice, as shown below. And before mount, please clean the mounting surface and adapter.
Mount S34.T2S/KY on the mounting surface directly or by a adapter. Please contact us, if you don’t mount it with stand, such as lean or lateral mounting.

Mounting notes:

Do not knock the moving part of the product to prevent flexure hinge deformation affecting the movement accuracy, or even damage the product.
Do not drop the mirror adhesive into the gap at the moving end, and do not have other objects to hinder the movement, so as not to affect the accuracy or damage the equipment.
Please select appropriate screw for the mounting connection, to prevent the mounting is not firm and mirror falls off, causing permanent damage.
Please pay attention to standard operation during the whole mounting and operation process. Users should carry out relevant operation under the guidance of professionals.

Load

When mounting the load, ensure that the load quality is less than the maximum load capacity of S34.T2S/KY, and try to mount the load in the center of the moving surface. The correct position to mount the load is shown below. COREMORROW-S34-T2S-KY-Tilt-Platform-FIG-18

For the protection of the product, we do not recommend that the load is too high. If a high load must be used, please appropriately low the position of the center of gravity of the load. The wrong mounting way is shown in the figure below.

It is forbidden to mount the load on one side of the moving platform, which will cause serious damage to the product, as shown in the figure below.

Notice:

When mounting the load, tighten the load slowly. The torque should not be too large to prevent damage to the mechanism.
Avoid stretching and bending cables.
Use the dedicated cable provided by Core Morrow to connect S34.T2S/KY and the controller.
Do not connect via an extension cable casually, if you need a longer cable, please contact Core Morrow.
