Piezo Actuators

Piezo Motors and Stages

Piezo ActuatorsOverviewWe supply various piezo motors and stages from CEDRAT TECHNOLOGIES. Stepping Piezoelectric Actuators (SPA) are new long-stroke linear or rotating piezoelectric motors for micro/nano positioning applications benefiting from proven APA® heritage....

Piezo Actuator Mechanisms

Piezo ActuatorsOverviewMainly based on the APA® concept, CEDRAT TECHNOLOGIES has developed different piezo actuator mechanisms in order to fulfil its customers’ requests for several degrees of freedom kinematics. These mechanisms take advantage of the APA® concept...

Amplified Piezoelectric Actuators (APA®)

Piezo ActuatorsOverviewPatented by CEDRAT TECHNOLOGIES, amplified piezoelectric actuators are a mechanical magnified preloaded stack of low voltage piezoelectric ceramics (MLA). The mechanical amplification is obtained thanks to an external elliptical shell made of...

Parallel Pre-stressed Piezo Actuators

Piezo ActuatorsOverviewParallel pre-stressed piezo actuators (PPA) are preloaded low voltage piezoelectric actuators using a direct-acting multilayer ceramic stack (MLA). Most conventional Direct Piezo Actuators use an MLA preloaded by Belville washers on the end of...

Piezo Drivers and Controllers

Overview

CA45 desktop piezo amplifier To fulfil various requirements in terms of driving and control conditions for its piezo actuators (static, pulse, dynamic), CEDRAT TECHNOLOGIES has developed 4 different families of piezo drivers and controllers:

CA45: Low cost, compact (1 channel) stand-alone linear voltage amplifier and power supply for precise quasi-static motion.

For more demanding applications, we offer a modular rack system with a combination of the following components:

LC75: AC-DC converter with stabilised output for low-noise supply of linear amplifiers.

LA75: Linear voltage amplifier with a choice of power outputs for precise dynamic motion.

SP75: Switching power amplifier for fast motion.

These standard drivers can be equipped with controllers and sensor conditioners. Note also that various new / customized drivers (such as switching amplifiers, oem products, space electronics) may be developed upon request.
