Extreme temperature motors from Wittenstein have been in use for over a decade in the most demanding environments - from satellites miles above the earth to ocean floor exploration.

The servo motor technology from Wittenstein ensures small size and high efficiency. These custom created servo solutions are specially designed to handle conditions where extreme temperature is the most demanding requirement.

Winding and magnet materials are at the heart of every motor. Temperature-stable materials and specially coated magnet wire ensure reliable system operation at temperatures ranging from -70°C to 210 °C.
