Piezo Drivers and Controllers

Piezo ActuatorsOverviewTo fulfil various requirements in terms of driving and control conditions for its piezo actuators (static, pulse, dynamic), CEDRAT TECHNOLOGIES has developed 3 different families of piezo drivers and controllers: CA45: Low cost, compact (1...

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 Motors and Stages

Overview

LSPS35XS linear stepping piezo motor stageWe 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. They operate by accumulation of small steps. The motion can be either linear (LSPA motors) or rotary (RSPA motors).

The motors can be supplied with the dedicated controller SPC45 or with standard Linear Amplifiers CA45 or LA75.

The Piezoelectric Motors SPA have the following outstanding characteristics and benefits:

High speed up to 70mm/s. Reduces cycle times and increases productivity
Blocking at rest. Power can be removed when the motor is in position.
Resistance to external forces (shock, vibrations). Ideal for embedded applications
Strong miniaturisation possibilities.
Non magnetic. The motor is MRI compatible and does not generate magnetic fields.
High resolution to the nanometre range if required.
Life time greater than 10^6 cycles
Severe environment compatibility (vacuum, cryogenic, clean environment…)
Few parts: cost-effective solution for series production

SPA piezo motors are targeting biotechnology, medical devices, aerospace, defence, microscopy, laboratory automation, materials characterization, digital imaging, recreational equipment, IC manufacturing and photonics.

Piezo motors provide the smallest size, greatest efficiency, highest precision when applied in these areas.
