Elliptec Actuator A10E - Elliptec - #1

A10E Datasheet

General Description

The A10E actuator consists of a preloaded piezoelectric element in an aluminium frame. The frame transforms the piezoelectric expansion into a lateral displacement at the actuator tip.

Features

• Preloaded piezoelectric element

• Motion amplified

• Low voltage of operation

Mechanical Properties

When an electric voltage, U, is applied to the piezoelectric element, the actuator tip is displaced by a distance x_U.

When an opposing load, F, is applied to the actuator, the A10E deflects like a rigid bar of length A that is connected to a flexural spring of stiffness k (for excitation frequencies less than R).
