Greetings everybody;

I just spent an hour on wikipedia, and another hour reading everything 
that google spits out on 3 phase stepper motors, and have not found a 
convincing argument in favor of 2 phase, other than their ready 
availability.

I can get off fleabay, 3 phase, 230 volt ac powered drivers in size & 
voltages suitable to move this lathe with, for a big buck + an if it 
fits box from the USPO. Those are here, on the left coast.

But no one on this side of either pond is stocking the 3 phase version of 
the motors, and due to their weight, its 2 to 4 weeks, and another 56 
bucks or so to get any of them because they are all in China, so an $80 
nema 34 is about $140 on my front deck. Close to $250 an axis IOW.

So I need to see a decent discussion on the subject before I cut that big 
a hole in the card.

Many thanks for any educational url's on the 3 phase motors you folks can 
supply.
 
Cheers, Gene Heskett
