Mounting a Stack Actuator
To prevent damage to the ceramic elements or electrodes, mount a bare stack actuator only at its endfaces. An encased stack can be mounted at the endfaces or clamped at its circumference. In coupling an actuator to a mechanical system, exclude bending, tilting or shear forces that could inhibit the stroke or damamge the actuator. A planar face and the center of a spherical tip provide suitable contact. Planar face contact is acceptable if one of the faces is free moving. If the stroke for an actuator proves insufficient for a particular task, an alternative to using a larger actuator, or multiple actuators in series, is to amplify the stroke by modifying the mounting configuration.
