Asked by: Keith Robinson
Subject: what voltage and cycles to power my Gyroscope?
Question: I have an ex military very old (WW11 I think!) bronze gyroscope. not sure if its powered by air or electricity.its got tubes which could be air or lubricant feeds. also has three terminals wired to the interior.
I can get it spinning moderatly by supplying it with AC 180V and using a capacitor to fake 3 phase of sorts.
I just need to know what CPS and voltiage it needs. its a Sperry Rand with 393/58 stamped on it. been trying for years to find out. could anyone help please?

 if there are grooves in the edge of the gyro i would guess air driven and the wires would be the feedback to the instruments especially if they are only for small wires.
