Features
压电驱动器压电体对电信号响应快、分辨率高、推力大，无磁场干扰同时也不受外界磁场干扰，且体积小；若在马达应用中，压电驱动器主要是依靠摩擦驱动，又具有低速、大力矩和高分辨率；同时无信号输入时，依靠静摩擦力又可使马达输出轴保持自锁，又由于其具有单位体积输出能量大、结构紧凑、形式多样、可控性好，在精密机械和自动控制领域中展现了良好的应用前景。
Product Details
Description:
A solderable conductive central electrode is bonded with two piezoelectric ceramic plates.
Both piezoceramic plates are poled in the same direction (Parallel Poled) as shown in the attached side view drawing.
The polarity of the bimorph actuator is positively marked on the top electrode as shown in the attached plan view drawing. The surface of the bimorph actuator is coated with special protection varnish.
Technical Data:
Driving Voltage: 150 Volts in the polarized direction
Operating Temperature: -250to 70 C
Storage Temperature: -40 to 85 C
Application:
A piezo ceramic flexure element which achieves approximately 20% greater displacements when compared to conventional piezo bimorph elements.
These advanced piezo elements are suited for applications as actuators,fuel injection valves, sensors, optical positioning,reading aids for the blind, textile machines and a host of others.
