The Nanomotor®
-
The patented Nanomotor® is a piezo driven linear motor. It is a multifunctional basic part for many positioning and manipulation devices. It has a positioning stroke of up to more than a centimeter while operating with atomic resolution. The Nanomotor thus bridges eight orders of magnitude. The Nanomotor consists of a cylindrical housing and a slider with a free axial hole inside. It combines high resolution in the sub-nanometer range with a large positioning stroke. The Nanomotor utilizes a piezo tube for fine positioning and a shock wave produced by the same piezo tube for coarse movements. The small Nanomotor is half the size of a match stick. It can lift six times its own mass. Every point of its stroke can be reached with a speed of up to 1 mm/s. The Nanomotor also works in ultrahigh vacuum or even under water. It is driven by a PC card at a supply voltage of only ±15 volts.

Thermal Vacuum Testing
-
When you want to test your product for extreme space conditions, that include temperatures from 155°C to -175°C at space vacuum altitudes, Environment Associates is your solution. Using this test to determine the unique failures of space mechanisms that orbit the earth is key in improving system reliability. Thermal vacuum testing is similar to thermal cycling but adds deep space vacuums for detecting corona/arcing and intermittence and increases a product’s out-gassing. The key failure modes found during this test are: 1) electrical iIntermittence, 2) thermal control issues, 3) arcing, 4) corona, 5) material out-gassing, and more, to determine a product’s flight-worthiness for workmanship and processing issues.
