Hoot,
I was ROFL reading your commentary in the blower article, and impressed with your expertise and the cool results. So now I have a Dayton 2C646 in my personal collection.
The Dayton pamphlet says to oil the motor every six months using only non-detergent( ML) oil. Interesting. I have never seen non-detergent oil for sale anywhere, not in 20 years. Where does one obtain this stuff? What will happen if I use the common detergent stuff? And how do you get the oil in? I see no openings or cups and the motor is riveted together.
I tried it out at 5V and it puts out a pretty good breeze; something like a 12 inch personal fan on medium speed. There does not seem to be any audible noise from the spinning fan cage, but the sharp sound of the brushes on the commutator is very grating.and annoying. I've never heard this sound from another motor, possibly because the other racket they make drowns it out. At 5V you can almost count the clicks at. Possibly there is less noise when it is mounted, but as it is, I'd say it is as grating as as a 38CFM Delta. I may end up abandoning the project .
Trying to get the people at Gainward to sell to me was interesting. They will ONLY sell to companies they say. I have never been to a distributor who refused to sell me something before. We went around in circles several times. But I acted very put out about it and insisted I could see no reason they could not sell it to me. So then the salesperson found some way he could do it. He said that in two weeks there would be ABSOLUTELY no way he could do this. (Too bad; they have a lot of cool stuff there.) After that you will probably have to special order it from elsewhere for $100 while they get it for $42 from Gainward.
There is an identical 120VAC version of this (2C647) and a 230VAC version. They just attach a different motor. I know there are AC motor speed controls. I don't know if they work with all motors, but that could an alternative and some AC motors do not use brushes. They do not mention brushes for the AC versions of this blower and call it a shaded pole.
Thanks for any comments from anyone.
Later: It's Grainger not Gainward.

). Maybe I could damp the wires' noise without disassembling the motor. I got my roll of Mortite rope caulk. It's like kids' modeling clay, but it comes coiled up like a rope. In its way, this stuff is as great as duct tape. From the texture, I know it has got to damp sound. I molded it around and between the wires and stuffed in into the exit hole. Oola! (French I think.) The grating sound went way down. I put another gob around the wires about a half inch away just for overkill. I can't judge how this is compared to the wire mod, but what it did is practically miraculous. Now it just makes a muffled swishing sound. I think it works by either blocking the sound from coming out of the hole, or decoupling the sound transmission to the motor case. I still can feel with my fingers the wires vibrating. Maybe if I wrapped them in something.
