Preloaded piezo actuator11/10/2023 ![]() ![]() Suitable for sophisticated vacuum applications Piezo actuators do not require lubrication and do not cause abrasion. 100 billion cycles without a single failure are proven. PICMA® actuators offer an up to ten times longer lifetime than conventional polymerinsulated actuators. All content in this area was uploaded by Daisy Shi on. ![]() This protects them against humidity and failure resulting from an increase in leakage current. CoreMorrow Preloaded Piezo Actuators Application in Additive Manufacturing.pdf. Please refer to piezoelectric actuators with casing selection guide for model selection.Preloaded Piezo Actuators For High Loads and Forces, with Position Sensor P-845 Outstanding lifetime due to PICMA® piezo actuators Travel range to 90 µm Push force capacity to 3000 N Pull force capacity to 700 N µs response time Subnanometer resolution Vacuum versions, optional water-resistant housing Application fields Static and dynamic precision positioning Fiber positioning Laser tuning Nanotechnology Outstanding lifetime thanks to PICMA® piezo actuators The patented PICMA® piezo actuators are all-ceramic insulated. The following are the ring piezoelectric actuators with casing offered by CoreMorrow, please click for details. ![]() The ring-shaped piezoelectric piezoelectric actuator has an aperture in the center, which can be used for the optical path to pass through or to meet the mechanical structure of special requirements. In terms of shape, preloaded piezoelectric ceramic actuators can be divided into ring Piezoelectric actuators with casing and cylindrical piezoelectric actuators with casing. ![]() The driving voltage of low-voltage piezoelectric ceramics is generally about 150V, and that of high-voltage piezoelectric ceramics can generally reach 500V or 1000V high-voltage piezoelectric ceramics have a lower electrostatic capacity, and the blocking force is generally much higher than that of low-voltage ones. The low-voltage piezoelectric actuators with casing is driven by low-voltage piezoelectric ceramics. Preloaded piezoelectric actuators with casing can be used for micro-positioning, valve control, shock absorption and sound wave generation. The high-voltage preloaded piezoelectric actuators with casing are driven by high-voltage stacked piezoelectric stack. So it is more suitable for other harsh environments.įrom the difference in driving voltage, preloaded piezoelectric ceramic actuators can be divided into high-voltage Piezoelectric actuators with casing and low-voltage Piezoelectric actuators with casing. Preloaded piezoelectric actuators with casing is a mechanical design of stacked piezoelectric actuator, combined with a flexible hinge support structure and a housing structure into an integrated structure to form a packaged piezoelectric actuator, making it possible to have high micro-displacement accuracy, strong stability, and at the same time make up for the shortcomings of stacked piezoelectric actuator that cannot withstand tension. Preloaded piezoelectric actuators with casing have small size, extremely high displacement resolution, fast response speed, and low driving voltage, large blocking force. Piezoelectric actuators with casing as electromechanical transducers can convert electrical signals into mechanical displacements and apply them to adjustment control systems. Preloaded piezoelectric actuators with casing can be used for micro-positioning, valve control, shock absorption and sound wave generation. ![]()
