Single-speed, Multi-speed and Segmented Resolvers
General Dynamics Ordnance and Tactical Systems manufactures exceptionally reliable single-speed, multi-speed and segmented resolvers.  Specifically designed to withstand high-impact (shock) and environments containing dirt, grease, oil or other contaminants, our resolvers and synchros are available in a variety of configurations including housed, unhoused and space-rated.

Common applications for General Dynamics resolvers include aerospace and defense platforms such as radar, missile seekers and electro optical stabilized systems.

Our resolvers’ absolute positioning sensors provide:

  • A high degree of angular accuracy
  • Extremely high resolution
  • Easy installation
Why Should I Choose A Resolver?

Resolvers are superior to many other kinds of absolute position sensors because of their ruggedness, and ability to provide a very high degree of angular accuracy under severe conditions. There are no optical paths to keep clear of smoke or oils that often disrupt the operation of optical encoders. Because they are a proportional device, they are also less subject to input signal anomalies; a voltage or frequency variance will change both the sine and cosine outputs equally.

Resolvers are a cost-effective answer to your control needs. They save you size and weight, being substantially smaller than other transducer approaches, and easily integrated into your system, component or motor design. Signal converters and balance circuitry can easily be incorporated into the resolver and/or output connector configuration.

Pancake Resolver Applications

A resolver is an electromagnetic transducers that can perform three basic functions: transmitting information, receiving information and correcting information. When precise positioning is required there are many ways to address the problem, but only a resolver can provide ruggedness of construction and high positioning accuracy in extremely hostile environments.
