Therefore, for dynamic applications, these actuators must be preloaded to ensure that the. Superior lifetime of our actuators is guaranteed with the patented ceramic-encapsulated multilayer production process. The parallel pre-stressed actuator is a preloaded stack of low voltage piezoelectric ceramics (MLA). Piezo stack actuators are extremely sensitive to tensile loads. This group is specialized in research, design and manufacture of piezo materials and components for motion control. We currently employ 180 staff at our piezo ceramics division " PI Ceramic". PI offers the largest selection of standard and custom piezo actuators and engineered subassemblies. They provide efficient force generation because no conversion from rotary to linear motion and no gears or mechanical other parts that require maintenance or lubrication are involved.
The following are CoreMorrow piezo amplified actuators, please click for details.įor model selection, please refer to the Selection Guide for Piezo Amplified Actuators.Piezoelectric actuators (also known as piezo transducers, or piezo translators) are based on the piezoelectric effect and convert electrical energy directly into linear motion with virtually unlimited resolution. To meet the requirements of the adaptive optics systems with high bandwidths and large excursion angles, we propose a fast steering mirror (FSM) with an ultrahigh natural frequency and a large angular range. The application of amplified piezo actuators is very wide, such as mechanics (new generation ultrasonic or sonic vibration, tool positioning, pick and place tools, diamond turning, elliptical piston machining, damping, dynamic control, NDT, Device fatigue monitoring, etc.), energy aspects (piezoelectric generators, energy recovery technology, electrical switches, etc.), optometry (FBG fiber Bragg grating deformation, optical lens positioning, micro-scanning, astronomy, focus positioning, laser cavity tuning, Fiber coupling and deformation, chopper, interferometer, modulator, PDP crystal cutting, etc.), fluidics (proportional valve, pump, flow measurement technology, inkjet technology, injector, droplet generator, particle flow meter, etc.) ), electronics (mask positioning, wafer or head processing, non-magnetic drive technology, circuit breakers, chip testing, etc.), aerospace (format control, active wing, active aileron, etc.), etc.
, Large output power and other characteristics.Īmplified piezo actuator is a mechanism design of the stacked piezoelectric ceramics, combined with the flexible hinge support structure, the amplified structure and the housing structure into an integrated structure to form a mechanism amplified piezoelectric ceramic actuator, which makes it produce larger travel, and feature high micro-displacement resolution and strong stability. Piezoelectric ceramics with multilayer stacked structure have small size, extremely high displacement resolution, fast response speed, and low voltage drive.
Piezoelectric ceramic micro-actuators as electromechanical transducers can convert electrical signals into mechanical displacements and apply them to adjustment control systems. Ceramic Insulated Piezo Actu-ators Provide Long Lifetime Highest possible reliability is assured by the use of award-winning PICMA multilayer piezo actuators. Piezo actuators can be used for micro positioning, valve control, shock absorption and sound wave generation.
