Fine Stepping Piezo Actuator (FSPA) is a patented actuator that combines SPA technology with mechanical reduction. This allows to achieve very small step sizes even down to 10 nm. Another major advantage of FSPA is its ability to maintain its position,while unpowered, even when very large outer forces or acceleration are applied. Typical speed for FSPA is 200 µm/s.
Typical application for this actuator is to finely tune the position of a component and maintain this position afterward even though environmental conditions may get real bad such as during off-road transportation, space launch or aircraft landing…
