I'm not an electrician, so use this with a grain of salt. I have
been around 440V and larger motors for 30 years and learned a few
tricks.
One guy I know bought a 3 phase lathe and wanted to put it in his
garage. He only had single phase 220 in the garage.
Someone I know came up with a rig that by God worked somehow, but
I don't know how efficient it was. It consisted of a 110V motor
and two 3 phase motors belted together. I believe the 3 phase motors
were 10 HP to run a 5 HP lathe.
A three phase motor will run on one phase, it just won't start.
A second three phase motor will work just fine as a 3 phase generator,
once you energize it.
What he did was get the whole thing started turning with the 110V
motor, then cut in the single phase 220 to one of the big motors.
He then momentarily hit the second motor with 110 and it would
start generating 3 phase power for the lathe.
Around here, used industrial 3 phase motors like that are pretty
common, along with heavy V belt drives.
Check with a real electrician or electrical engineer before you try
this.
