I'm a little envious that you have enough parts to run at least two Model-5 sirens on single phase. I don't know if my ancient 3-phase Model-5 will ever be run again but I'm glad I rescued it from being scrapped. I grew up hearing that siren in my youth. I refer to it as a Model-5 but the truth is there's no model number plate on the housing, only the motor name plate which says it's an AV37X. The motor is 7.5-hp. Presumably the Model-5 got it's name from having a 5-hp motor. Another group member posted some pictures of the same model as mine in 2011. Here's the link.CDV777-1 wrote:No. The motor hasn't been used. It was a new old stock spare I got with a load of stuff several years ago.That's a big commutator. Did you resurface it?
I got three model 5 motors, three stators and two rotors from a power company that had them as spare parts along with a ton of other unused spares
that they bought from Federal probably in the 80s some time. The parts were spares for their nuclear plant warning system.
As far as I know the motors had never been run before I got them. They still had the wax sealer and tags on the motor shafts when I got them.
I was supposed to get 3 rotors but they shorted me one rotor so now I have an incomplete siren. I just need the rotor. I doubt I'll ever find one.

Mine is in better condition because it was in service until a few years ago. I'm pretty sure it's a pre-war model. I assume it had regular maintenance to make it last so long. For some reason it doesn't have the lower cowl like all the Model-5's I've seen. I can't say for sure if it didn't come with one, but I never saw it in the sixty or more years that the siren was used in my town. I've tried to find out more about the history of the Model-5 but I haven't had much success. Does anyone here know when the Model-5 was first made by Federal?
Thanks
