Inneresting Baldor Motor
Awl --
Did Baldor munge a 5 hp 3 ph into a big-assed 5 hp *single phase*?? Nice motor, of course. But with *3* large oil-filled caps, like what you would find on an rpc. AND it's reversible! Which leads me to believe it is actually a 3 ph. motor, with starting caps. Four wires are in the junction box, two thick, two thin, with a thick/thin tied together. I think you reverse the motor by exchanging the two thick wires, just as on a 3ph, and apropos of reversing a statically converted motor, as in the rpc ganging thread. A likely scenario??? Too bad they didn't bring out more wires, so's you could have the option of using it as an unencumbered 3 ph motor. Funny thing: three wires are coming from the caps to the motor. Poss. distributed across L1-L3 *and* L2-L3?? I don't think one wire is a ground, didn't ring anything out yet. -- DT |
