Predestined actuator for smart applications
Whenever an application needs movement, positioning, displacement or any other kind of motion, the best type of actuator must be found. The development of innovative solutions is accompanied by the selection of ideal mechanical, electrical, thermal, magnetic and other actuator technologies. Speed, acceleration, power and of course energy consumption are critical operating parameters.
Comparing all the performance metrics, you will soon discover that Piezoelectric benders are perfect for many applications that you have never thought of. Piezoceramics outperform many competitive technologies, since every Piezo actuator can also be used as a Piezo sensor.
Since our bending actuators are only operated in the direction of polarization, these smart actuators experience a refreshment during each bending process. The deflection and the force are maintained throughout the entire working life. Due to the very high speed of deflection, productivity is increased many times compared to any other types of actuators.
As a result of its compact design, the Piezo bending actuator takes up significantly less space. Its energy requirement compared to an electromagnet is considerably lower, which is reflected in the low operating costs.
Modifiable Piezo bending actuators to suit your application:
Extremely versatile control element
For application under special climatic conditions our bending units are additionally provided with a sealant consisting of a specially developed protective coating.
The standard bending actuator is a compound of two piezoceramics with or without an intermediate layer, the so-called bimorph or trimorph. For certain applications monomorphic bending actuators in which one of the two ceramics is not included and multimorphic bending actuators which include numerous active layers are also used.
A special actuator design, but also the use of highly effective ceramics make it possible to meet requirements relating to deflection and force. Bending actuators are predestined to replace solenoids not only in the form of control elements.
Our Piezo bending actuators easily have a working life of many billion switching cycles, smoothly integrated into the application. Because of their high reliability any downtime periods become a rare exception.
Its design enables deflections of several millimetres, forces up to several Newton and short deflection times to be achieved. Therefore, the Piezo bending actuator can be employed as a high performance, silent operating and fast-reacting control element without any heat evolution.
