I'm hoping people will actually use the AC motors as motors
Have thought about a cheap DC motor as inductor, but laminated steel isn't the best material, but worth some experimenting maybe. A reluctance motor might make a better air-gap bridge between coils than a squirrel cage.
That toroid at 60μ looks to be about 3800 NI @ %30 rolloff, so targeting 152 amps at 83uH effective? Interesting looking at the 125μ high flux, it really holds on to its AL value, for the same turns it looks like 128 amps at %30 rolloff, but the effective inductance at 128 amps bias is 172uH.
I am finding the 125μ in sendust to be more of a liability where high dc current is desired.
Does skin effect vs diameter count if all the wires are touching? do they need to be individually varnished to have a "skin"? And does skin effect only apply to the ripple current?
"Hence current will tend to preferentially flow near the skin of the bundle of wires, just as it does with a single solid conductor of similar overall diameter."
Edit, if I'm doing this right, the high flux at 125μ would deliver 184 amps at the same effective inductance @ ~18 turns.
