Re: [CAD_CAM_EDM_DRO] 3-Phase converter

You can make a 3-phase motor start, although kinda slowly until it "kicks
in", by feeding the "third leg" from a capacitor of the RIGHT electrical
size, which is connected to either of the two single-phase lines. The
resulting rotation is some fraction (about half? 2/3?) of the "normal" hp
you would get if using "proper" 3-phase. I do NOT know how to calculate the
correct capacitance (number of µF) per amp, but I THINK the current through
the capacitor should be about the same as it is in the line NOT connected to
the capacitor. Not sure. I have only used "store-bought" motors connected
in this way, "from the factory". They take a few seconds to "come up to
speed", but are otherwise very much like a 3-phase motor running on "true"
3-phase. Duh...
