Casing the piezo ceramic stack generally protects the main body from mechanical shocks and minimizes the influence of the surrounding environment. In a typical piezo actuator stack, a constant force pushing the stack (known as preload) is required, and this mechanism is incorporated within the casing. This allows for the handling of tension, which is not inherently present in piezo actuators, enabling dynamic operation. As a result, the piezo elements from Piezo Mechanics become even more user-friendly. 【Features】 ■ Protects the main body from mechanical shocks and minimizes the influence of the surrounding environment ■ Enables the handling of tension, which is not inherently present in piezo actuators ■ Allows for dynamic operation *For more details, please refer to the PDF document or feel free to contact us.

The structure is essentially the same laminated structure as the bulk stack. There is a hole in the center. The purpose of this hole is to facilitate optical alignment or electrical and mechanical design. Another advantage is that it allows for a larger diameter compared to a bulk stack with the same cross-sectional area. This increases stability against bending and shear stress, which is beneficial. Especially when a long actuator is required, the capacitance decreases, leading to reduced power consumption, which is advantageous. In dynamic applications where self-heating is expected, the ring structure offers good cooling efficiency and ensures greater flexibility. In terms of performance as an actuator, such as stroke, the ring actuator performs better.

The "stack actuator" is made up of independent multilayer piezoelectric elements or electrostrictive (electrostrain) ceramics. Typically, its cross-section is circular or rectangular. When a voltage of a specified polarity is applied, the stack elongates in the axial direction due to the d33 effect. The elongation rate can reach up to 2%. Please ensure that the mounting direction of the ceramic stack allows for force to be applied only in the axial direction. 【Features】 ■ Made of independent multilayer piezoelectric elements or electrostrictive (electrostrain) ceramics ■ Typically has a circular or rectangular cross-section ■ When a voltage of a specified polarity is applied, the stack elongates in the axial direction due to the d33 effect *For more details, please refer to the PDF document or feel free to contact us.

The "piezo actuator" that we handle is a positioning element that applies the piezoelectric effect of piezo elements, capable of accurately positioning from extremely small ranges of about nanometers to several hundred micrometers. Since piezo elements are made of ceramics, they are very hard and can generate significant force. They are also compact and serve as fundamental elements of energy-efficient products, making them likely to be adopted in many products both now and in the future. Our company has created a document titled "Basic Knowledge of Piezo Actuators," which explains the characteristics of piezo elements and various points about "piezo actuators." ◆ Here’s a brief introduction to the contents of the document! - Characteristics and disadvantages of piezo - General properties - Operating modes - Types of actuators *The document can be viewed via the "PDF Download" link below.
