Piezo Actuators from APC
APC International offers a wide range of standard and custom piezo actuators for use in a variety of different applications.
A piezo actuator converts an electrical signal into a precisely controlled physical displacement, to finely adjust precision machining tools, lenses, or mirrors. Piezoelectric actuators are also used to control hydraulic valves, act as small-volume pumps or special-purpose motors, and in many other applications. Piezoelectric actuators are unaffected by energy efficiency losses that limit the miniaturization of electromagnetic motors, and have been constructed to sizes of less than one cubic centemeter. Another potentially important advantage of piezoelectric actuators in a motor application is the absence of electromagnetic noise. Further, if physical displacement is prevented, a piezo actuator will develop a usable force.
A stack actuator is constructed in one of two ways: discrete stacking or co-fired depending on the user’s requirements.
A stripe actuator or bending actuator, in which thin layers of piezoelectric ceramics are bonded together, allows the actuator to bend with a greater deflection but a lower blocking force than a stack actuator.
