Hi all
I’m Looking for recommendations on a rotary pahse converter for my small shop (at present I have ruled out static). I will have at least 4 machines with 3-phase motors so I think replacing the motors is not financially attractive.
Max load I anticipate at any one time = 6 hp (2-3 hp cyclone + one machine up to 3 hp). There are quite a few offerings out there — from Phase-a-Matic & Cedarburg, to mom-and-pop shops that make ’em from used electric motors, to kits. Lots of stuff on eBay.
Can I get something decent for less than $500?

I made my own probably about 15 years ago using an article from Fine Woodworking. It was an excellent article that provided all of the electrical specifications. You might want to look at their back issue index which is online. It really isn't all that complicated and you can find the most expensive piece, a large 3 phase motor, used from many different sources. I've run a large 5 HP radial arm on residential power without problems, although you should check local building codes given that many areas don't allow electric motors larger than 5 HP in residential areas. I hope that this helps.
