Small Volume High Temperature Resistant High Output Preloaded Piezo Actuator

Update time：2024-01-15 14:38:14Clicks：988second
The preloaded piezoelectric ceramic actuator is a combination of stacked piezoelectric ceramics and flexible hinge support and housing. It has the characteristics of small size, high displacement resolution and fast response speed. It is very suitable for machine tools, active vibration insulation, adaptive mechanics, scanning microscopy, laser tuning and other applications. Because the external shell compensates for the shortcomings of stacked piezoelectric ceramics that can not withstand the tension, the preloaded piezoelectric ceramic actuators are more stable and more suitable for other special environments.

Now we introduce a series of preloaded piezo ceramic actuators with small volume, high temperature resistance and high output provided by CoreMorrow. It uses the principle of piezoelectric longitudinal effect to convert electrical energy into mechanical energy such as displacement or force. Based on the unique component structure design and the composition of piezoelectric ceramic materials with high electrostriction coefficient, it is smaller than traditional piezoelectric ceramic actuators, but it can generate greater force and displacement at low voltage. The product is shown in the following figure.

This sealed piezoelectric actuator has a displacement of up to 140μm, an output of up to 800N, and an operating temperature range of up to -40~150℃. Due to the metal sealed design, the internal ceramic is isolated from the atmosphere and is less affected by external environmental factors, so it has a longer service life and higher performance, which is ideal for a variety of high-reliability applications. Built-in preloading mechanism and mounting accessories for easy installation into the equipment. We have actuators with internal thread, actuators with flange and actuators without flange.

Typical Applications



Fine tuning of various X-Y workbench steppers, mirror/prism positioning, linear motors, fluid flow control valve drives, vibration sources and manipulators.

Application Examples



1.Mirror/prism positionin：The sealed piezoelectric ceramic actuator can be used as the driver of the mirror/prism, and the position of the mirror/prism can be adjusted by applying voltage to make the piezoelectric ceramic actuator produce small deformation, so that the optical path can be deflected or reflected.

2.Fluid Flow Control Valve Driver：Fluid flow control valve is a common device for controlling fluid flow, which controls the flow of fluid by changing the position and shape of the valve. The main components include valve, valve seat, valve stem, driving device, etc. CoreMorrow piezoelectric ceramic actuator can be used as a driving device to control the valve movement. Because of its high precision and fast response speed, the valve can be accurately controlled by applying voltage.

3.Nano-manipulator：Nano-manipulator is characterized by micro - and nano-level motion control operation and processing of micro-sized objects. CoreMorrow piezoelectric ceramic actuator can be used as the executive device of the nanomanipulator to provide micro and nano level motion accuracy, which is used to change the pose of the object, sample, etc., including the adjustment of the motion range, motion accuracy, the linear distance of the motion or the Angle range.

4.Cell Penetrating Peptide：Piezoelectric ceramic actuators can move accurately at the nanoscale, and drive the probe or sample cell to do nanoscale movement, and accurately send the probe into the cell without damaging the cell structure, which has been widely used in biotechnology and life science and other fields.

5.Vibration reduction：In many mechanical systems, such as the aerospace and automotive industries, vibration needs to be avoided or eliminated. When the vibration is detected in the vibration monitoring system, the electric signal is applied to the piezoelectric ceramic actuator to make the piezoelectric actuator produce a displacement opposite to the vibration direction, so as to offset the vibration.
