CoreMorrow high voltage preload piezo actuators integrate high-reliability high-voltage PZT piezo stack inside, protected by stainless steel casing, and high internal mechanical preload force can be used for high-load, high-dynamic applications with strokes up to 260μm with blocking force of up to 50000N and nanometer resolution, it is very suitable for scanning microscopy and laser tuning applications. Closed-loop version integrates high-precision SGS sensor internally to eliminate the problems of hysteresis and creep of the piezo ceramic, and improve its repeatability and stability.
High Voltage Preload Piezo Actuator
High-voltage preload piezo actuator has driving voltage of 1000V and built-in high-output piezo stack with an blocking force of 50,000N. It is mainly used for dynamic applications with large loads.
Features:
· Stroke to 260μm
· Load to 70000N
· Low electrostatic capacity

Large blocking force
Higher height, Larger displacement
High Voltage Ring Preload Piezo Actuator
High voltage ring preload piezo actuator has driving voltage of 500V or 1000V, ring-shaped actuator with through hole in the center, and external metal casing package. The interior of the high-voltage ring-shaped piezo actuator is preloaded and pretensioned by mechanical spring, making it ideal for dynamic applications.
Feature:
· Stroke to 130μm
. Could withstand tension
· Aperture 25mm
Multiple apertures
High-voltage ring piezo actuators have 4 standard apertures: 4.5mm, 7.5mm, 14mm and 25mm.
Fixed mode
High-voltage ring preload piezo actuator is fixed by 4 internal threads at the bottom, and the external threads at the top are connected to the load. The standard product is equipped with a lens fixing cap to facilitate the fixed installation of the lens.
Thermal stability optional
CoreMorrow provide "thermal stabilization device" to achieve dynamic operation. Heat can be efficiently transferred from the piezo stack to the case. The case material is a highly efficient thermally conductive metal. The power of the thermally stable structure can be increased by 2 to 3 times.
Recommended Piezo Controller
High-voltage preload piezo actuator is driven by high-voltage controller. CoreMorrow E00 / E01 series high-voltage piezo controllers have variety of input control options and can output 0 ~ 1000V high voltage. We also provide piezo controller customized service, according to the requirements of specific use, customize the output voltage, frequency, power, volume and other parameters.
