Hello all...
I was recently given a small furnace blower unit with motor. I'd admit that it was so small I made the assumption it ran on 110 volts AC and powered it as such for a quick "go/no go" test since it had been sitting out in the weather. It ran, but only very slowly and only for a few seconds until I pulled the plug. Nothing got hot, no apparent damage was done.
After extricating the motor from a heavy load of restaurant grease, I found that it is really a 208-230 volt single phase motor. (I'm in the US for what it's worth.) It has four speeds and is wired something like this per the label and contents of the wiring box:
BROWN - Capacitor ORANGE - Capacitor ORANGE - Line (hot) SPEED1, 2, 3 or 4 would be connected to the other hot line depending upon which one you want to choose.
I don't have easy access to a 220 volt power source. I could arrange things so that I do, but that's a lot of work when I have this handy, sufficiently heavy 110 to 220 step up transformer available! I'd like to know if it would be safe to power the motor with that transformer for testing purposes. (My plan, should the motor work, is to clean it up and sell or trade it for a
110 volt motor to use with the blower wheel.)William
