Denver duplex motor (help)

[fullsendersonly]

Hello all, I have a good topic to uncover, I can’t find a motor that matches this one on a Denver duplex. I would like to find a compatible motor it is a three phase siren.

Are you trying to go for a full restoration? Otherwise any motor with the shaft horsepower will do regardless whether it's single-phase or three-phase. Modern electric motors are more efficient too.

I'm only trying to restore the old motor because it is vintaage. not a full restoration, I am just trying to get the motor running again. about 15 years ago it ran for 2 hours continiosly and the motor burnt up and shorted out. Would it be possible to bring it back?

I can't see why not. Electric motors are rebuilt all the time. To have it professionally done will probably set you back a few hundred dollars.

I'm guessing the motor will need new windings and bearings at a minimum. You'd have to pull it apart to know for sure. Fortunately it looks like the motor is connected to the rotor with a coupling, unlike many sirens where the rotor is pressed onto the motor shaft, so that's less to take to a shop to get it looked at.

thanks for the info because this will probably be the only siren that I will ever have to do this much restoring for.

Pretty sure this is a kid blowing smoke....last time I spoke with the fire department, there were no plans to restore this. It was decided to make it a static display and leave it at that.

The reason the siren ran for 2 hours was most likely due to water infiltration in the motor. It ran until power was cut to the tower and locked up upon wind down.

The motor is a 1920s era General Electric. Those are actually fairly common given they were produced in high volume for a multitude of uses.

Infact, I'm 99% sure these photos were stolen from Tristan G.

they are my photos dude so please stop saying I stole them I'll attach a video of mine about it. and they were originally going to powder coat it and put it on display but that never happened I got into contact about it so please don't accuse. here is the video proof. https://www.youtube.com/shorts/JATzQGsKmKs
I just took this video Sunday. same with the photos also thank you for the motor info. previously I have already established it is a 1920s era motor as you have sad. also I'm pretty sure Tristan w. didn't take a photo of the motor tag from what I can find.

also I managed to remove the obstruction in the rotor and spun it up by hand. video: https://www.youtube.com/shorts/37wEmsH6rXQ

I stand corrected. Hopefully this comes to fruition and that thing gets a second chance at life. I look forward to seeing it's progress.

You'll have to forgive me, there has been a lot of erroneous BS posted on this forum as of late, so it's hard to take a lot of posts like these seriously.

I do have a motor tag shot Tristan sent me, that said
The accompanying motor would likely be better to repair than replace, as it should be original to the siren. The WM A Box tag on the siren places this siren 1920 and later, as earlier sirens had "Dillon-Box" on the tag.

I am sorry for firing up. I have just had a hard time with making friends or people who will believe me. Also thankfully there is a few electric motor shops in Boise Idaho for me to take it to.
