We apologize for any inconvenience this may have caused, and invite you to look at our available piezo products. The following are the square piezoelectric actuators, please click for details. These piezo products have been discontinued. For the simulation, we apply 50 volts to the layers. The model also includes a stainless steel substrate and a seal of hyperelastic material over the through hole of the valve. In terms of shape, piezoelectric actuators can be divided into square piezoelectric actuator and ring piezoelectric actuator. The valve model consists of a multilayer stacked piezoelectric actuator, which in itself is a complex structure of stacked layers and electrodes. The composition structure of high-voltage piezoelectric actuator has thicker piezo layer inside than that of low-voltage, so can withstand higher voltages. The driving voltage of low-voltage piezoelectric actuator is generally about 150V, and the driving voltage of high-voltage piezoelectric actuator can generally reach 500V or 1000V High-voltage piezoelectric actuator have a lower electrostatic capacity, and its blocking force is generally much higher than that of low-voltage. These actuators use the piezoelectric effect to generate linear displacements from 0.1 to 0. Piezoelectric actuator with multilayer stacked structure have small size, extremely high displacement resolution, fast response speed, and low driving voltage, large blocking force and other characteristics.įrom the difference in driving voltage, stacked piezoelectric ceramics can be divided into high-voltage piezoelectric actuator and low-voltage piezoelectric actuator. Also called piezo stacks, longitudinal piezo actuators are created by layering multiple piezo elements on top of each other, thus combining the effect of each element’s expansion to produce a useful movement and force. Piezoelectric actuators as electromechanical transducers can convert electrical signals into mechanical displacements and apply them to adjustment control systems. The SR rings stacks are perfectly matched to the range of PiezoDrive. Piezoelectric actuator (piezo stack) are also called stacked micro-displacement piezoelectric ceramics or multilayer stacked piezoelectric ceramic micro-motion actuators, which can be used for micro-positioning, valve control, shock absorption and sound wave generation.
