Piezoceramic stack actuators
Piezoceramic stack actuators are made by stacking monolithic multilayer
elements having alternating ceramic and electrode layers.
The axis of the stack is the axis of a linear displacement.
When voltage is applied, the thickness of the layer increases.
As a result, the total length of the stack increases as well.
The stack actuator is a rigid structure having a high capacitance and consisting of
a number of piezo layers assembled into a monolithic unit by the sintering method.
A small displacement of each layer is summed into a total displacement from several
microns to dozen microns with the developed force being from hundreds to thousands Newton.
| There are two types of piezoceramic stack actuators design: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
APPLICATIONS | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
precise masks alignment in photo and X-ray lithography;
precise tool supply in medical equipment;
stand displacement for optico-mechanical devices (gas analyzers and dose meters control);
beam control in optical fiber devices;
adaptive optical systems, adaptive telescopes;
P-1 ÷ П-5 are intended for parallel displacement of optical elements in quantum generators;
PS-4, PS-5 are used in ring type quantum generators for automatic control of constant optical parameters;
PS-11 ÷ PS-14 are designed for linear displacement piezoceramic drivers.
