A friend has acquired an elderly lathe with a dual-wound 3ph motor. It
has 6 wires going in to it, and is intended for 415v 3ph UK supply, but
he only has a normal single phase 240v domestic supply. He has been told
that he cannot use a single to 3ph VFD with dual-wound 3ph motors. Is
this true? If so, why?

I have a similar problem with a 2hp, 3ph Delta Unisaw motor. I looked
into buying a converter (VFD) and the price (260 plus or minus) was more
than buying a new single phase motor ($245 for 1-1/2hp). Also with the
losses developed with using a convertor, my original 2 hp, 3ph would
probably be no more than the effective output of a 1-1/2hp single phase
motor.

BTW, anybody want to buy a 2hp, 3ph Delta Unisaw motor? Condition
unknown since I have no 3ph power to test it.
