Aerospace - Military Resolvers


Resolvers provide accurate position and velocity feedback as well as commutation in precision equipment, without the structural or temperature restrictions imposed by other electronic feedback devices. They are resistant to the shock and vibration levels often encountered in military and aerospace applications.

These resolvers are available in standard sizes, or with custom modifications. Our engineering department is available for consultation to help tailor a resolver to fit your needs.


  • 1, 2, 4, 8, 16, 32 and 36 speeds standard; others available
  • 400 – 5,000 Hz frequency range standard; frequencies up to 20,000 Hz available
  • High immunity to electrical noise
  • Rugged design to meet demanding environments – no glass discs or optics to fail
  • Compact design
  • Mounts directly to shaft and housing – no coupling devices needed
  • Brush or brushless designs
  • High reliability – long-life design; no bearings or electronics
  • Custom modifications available

Integration Capabilities

  • Ideal for vertical integration with brushless motors and slip ring assemblies
  • Commutation of brushless motors
