Hi all.
I recently salvaged some parts from a dust collection system. After some hassle, I was able to isolate the hefty motor from the squirrel cage, and now I want to test it. I know that some motors like this one can be switched from 220 to 110 operation by means of jumpers on the motor, but this one doesn't have that, so it looks like I'm stuck with 220. Discussions here and elsewhere have convinced me that trying to power it with standard American 110V is not a good idea, even though it might work for awhile. Some have suggested using a VFD, which I don't have; I'm wondering if the answer isn't staring me in the face in the form of an outlet in my house that appears to be wired for 220.
Attached are some pics showing the motor and the outlet in question. If the outlet is wired correctly for 220, I should have two hots and a neutral, meaning that a volt meter connected between neutral and hot #1 should give a reading of 110V, and similarly, a meter connected between neutral and hot #2 should give the same reading; to power my motor I'd need the round plug to connect to neutral, and the other two plugs each to receive 110, adding up to 220. Have I got this more or less right?
