Piezo Actuators

Piezo Motors and Stages

Piezo ActuatorsOverviewStepping 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...

Piezo Drivers and Controllers

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

Amplified Piezoelectric Actuators (APA®)

Piezo ActuatorsOverviewPatented by CEDRAT TECHNOLOGIES, the Amplified piezoelectric actuator, is 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 Actuators (PPA)

Piezo ActuatorsOverviewThe PPA is a preloaded low voltage piezoelectric actuator using a direct-acting multilayer ceramic stack (MLA). Most conventional Direct Piezo Acutators use an MLA preloaded by Belville washers on the end of the stack, enclosed in a rigid case....
