This might go against the grain a bit.
Why not try it with the factory windings. Send high voltage to a transformer near the batteries.

Just curious mostly.

Surprised you suggest this, given the number of times using transformers has been discouraged on the board. A 4-pole motor conversion operates at a very low frequency, especially at cut-in. Below 10 Hertz.
Despite this, I might have tried it anyway, but I don't have 3 matched 2:1 transformers rated for 500 VA or so...

Same here. Or the freq is over 17KHz (steppers).

A guy who used to be here would have said use a transformer, I think.
Nobody talks about them any more.

quoting myself: "I don't have 3 matched 2:1 transformers rated for 500 VA or so..."

Correction, only need two now... found a 1400 VA UPS today (same place as the Tektronix)
