Documents: Synchro and Resolver Handbook and Guide

phoenixcomm

imageIf you work with robotics, avionics, an other fields that use angles you might just run into one or more these things. They are motor like devices that can transmit, or receive angles called Synchros in older aircraft they are used in pairs, imagea transmitter (tx) and a receiver (rx) . As you can see in Figure 1 by moving CG the CR will move exactly in step with its counter part. This figure is from Synchro Application Guide. There is lots more information in the Synchro handbook.

    I set up a loop where I would only allow the servo to move about 5 degrees at a time, I forget how quick the loop ran, probably about ten times per second..

    That implementation stops the servo from trying to do instantaneous movement from one position to another.

    You can change how often you allow the servo to move and how much you allow it to move, you have to adjust these values based upon the load you have on the servo..

    The end result is that you can achieve a very controlled movement of your sensor.

     small world!  I never made it back east for the flight test as it was considered a minor retrofit and our field engineer handled it.

    Those were the good old days - our Litton facility in San Fernando Valley was located next to farmland.  Nowadays that area is all shopping malls and has a few high rise buildings.

      You do realize that a synchro and a resolver are not the same animal. Synchros have 2 wire rotor with a 3 phase stater.   is very different. it has 1 input winding and 2 output winding ie 4 wires, The resolver is basically  transformer that is wound in quadrature form. as it  name implies it resolves angles. ~~ Cris

      ralphjy   Never guess who I worked for on the Island? Duh, yup Mother Grumman! and You will never guess where our lab was? Nope. In the building that had the E6x Antenna on the damn room!! And our two PE machines where under it. Across the hall from the F16  no fuselage but every movable part on B-Line strut that you can buy at you local electrical distributor, I think they called it a Green Monster as the strut was green. LOL ~~ Cris
