Detailed Description

Synchros and Resolvers are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals. NAI offers five smart function modules that cover the range of excitation voltages/frequency, include extensive field-parameter programmability, and provide a full operating envelope choice for interfacing to virtually any type Synchro or Resolver. A Resolver-to-Digital or a Synchro-to-Digital converter is used to convert these signals to a digital output corresponding to the shaft angle and/or velocity.
