Only the single phase models have brushes. A single phase 2T22/3T22 (2T22B & 3T22B) will draw around 52-58 Amps at 240v AC according to the manual. This can depend though due to the brush angle, so I usually say it will draw around 50-65 amps when running. You can also take a cord and test it with 120v, which will run it up to about half speed. It'll only draw about 20 amps since it is a repulsion-induction motor, which draws more amperage when it is running at full speed, and less amperage when running at a lower speed. Hope this helps.

Thanks for the help! I'll try it. If i get anywhere with it I'll let you guys know. Since it is a 3t22 should I be careful with the wiring for the solenoids? How is it wired?

If I were you, I wouldn't worry about them at the moment. For now my priority would be making sure the motor works and then moving on from that point. Only hook the 120/240v up to the two leads coming out of the motor, and not anything else.

Thanks i will!

You should post a video of it if it works. I'm sure we'd all love to see it running.

I will when i test it at 120v and if I can do it at 240v

Update on the Centerhill 3t22 project:
I haven't been able to get up there to work on it. And unfortunately the only supplier of information about the siren has stopped telling my dad about it and I can't get to the siren with a way to test it. Maybe it'll sit there forever unfortunately. Plus they're not to keen to a high schooler working on the siren.

I know everyone hates a bump but here it is.

Recently I've been talking to a guy who Centerhill VTF has contracted to fix their 3T22. This happens to be the same person who I've gotten to rewind my 7 1/2 HP blower motor and he has asked me to help him because I have connections to parts (Here). I will be relying on you guys to help me find parts.

The springs that hold the brushes to the armature are for the most part worn slam out and/or have broken completely. Any leads to similar style of brush holders?

And slightly off topic but their AF timer is the older style one.

Found springs! Thanks. I'll let you guys know more when it's worked on again.
