hpower Actuators – Description

hpower solid stack actuators are comprised of our smart PZT ceramics, optimized to deliver high power with dynamic performance. hpower stack actuators are unique with a disk layering design, and serve as the straight forward solution to many applications. These actuators feature a motion range up to 260 µm and higher upon request – with forces up to 50kN.

All of our piezo actuators have both encased and bare stack options, with and without a preload. Preloaded actuators allows for increased dynamic capabilities by protecting the system from problematic tensile forces. Encasing the actuators also protects them from the environment, and can be augmented to allow for operation in vacuum conditions and increased thermo-stability for longer run times. All of our actuators can also have acceleration/force measurement and position systems integrated.

The PSt series comes without casing and without a preload. The PSt VS series comes with casing and with a preload. There is a wide variety of hpower high-power piezo actuators (stacks and rings) available for applications such as materials testing and shock generation.
