A high resolution feedback device that is an alternative to encoders. Resolvers use inductive coupling to determine rotor position. Since resolver signals are not discrete, resolution is determined by the amount of interpolation used in the interface circuitry of the drive or controller.



  • Resolvers are suited to harsh environments such as high temperatures and severe vibration since they do not rely on optical sensors or glass disks which can fail in these conditions

ADVANCED Motion Controls' Capabilities

  • DigiFlex® Performance servo drives with resolver feedback have 12 and 14 bit selectable resolution to achieve 4096 and 16384 counts per resolver cycle, respectively
