Motors and Resolvers
Ducommun LaBarge Technologies
Resolvers
Ducommun resolvers are designed for extreme environments that range from vacuum and extreme cold
of outer space to the high pressures and temperatures of oil and gas exploration applications.
They contain no
internal electronics or optics and are unaffected by electrical noise, heat, shock and vibration.
The angular position sensors are used in most severe environments as required in the Space,
Aerospace & Defense and Oil Service Industries.
