Does anyone have any info on what is called around here an "austrailian 3-phase" set-up. The process involves running 240 single phase through an old 3-phase motor, so as, the 3phs. motor generates the third leg. You use a 110 "pony motor" (v-belts connecting), to get the 3phs. motor spinning. I have an old drill press I plan on powering in this fashion. I trust the old machinist I bought it from to get me up and running in this fashion, and I also know of a local machine shop that powers all there machines like this. I was just wondering if anyone had any additional info, such as 3-phase motor sizes, and apprx. amps that are acheivable. If this makes sense to you, you are probably the person I need to talk to. Thank You Adam
Reply:Check out Lindsay Books:http://lindsaybks.com/They have a couple books on the very subject. You can do this sort of thing for a three phase motor, but you lose efficiency. Should be ok for a drill press unless you are doing really heavy work and need a lot of torque. This setup does not work for a three phase welder.
Reply:Hey,thanks for the info. It looks like they have alot of interesting books.

efinitely a good source of information. I add a few of the books to my library each year. Was recently able to help a guy re-babbit his bearings after he was complaining that nobody knew how to do that anymore!

Reply:Several articals here:http://www.metalwebnews.com/msc.htmlAlso, If you have a EE degree, look for old usenet postings by Fitch Williams in rec.crafts.metalworking. For extensive theory of operation and performance analysis.
