I am putting together a small machine shop in my pole barn and I  am considering buying a phase converter.   My Machines are: (1) 3 hp vertical mill (1) 2 hp vertical mill (1) 1 hp surface grinder also would like some growing room for a later date.    I have 200 amp electrical 220 single phase   My Questions are: (1) can I connect and run three machines at once to the converter? And if so ,do I need a converter rated at the total of all my motors? (2) will my static converter have any value to me once I go rotary?   I am thinking a 5 hp converter, But I dont know enough about it to say.   Thank You, Robert   Robert J.

Robert, may I offer a second idea...? Simply replace with new motors that are intended to run on single phase, similar money and better response. Save the other motors to reinstall if you sell them. -randy- ** The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, don't fail to listen to suggestions. -randy-

Robert, If you get a quality phase converter you will be able to run more than one machine at a time. We have a 10 hp rotary phase converter in our shop and we can run up to thirty hp from it but no one motor more than 10 hp. Look for a converter that has some bulk to it. I've seen what is supposed to be a 15 hp settingup on a little shelf while our 10 hp is over three hundred pounds and I wouldn't consider any place for it but the floor. I don't know about your use for a static after you have the rotary. All I can talk about is what little I know through personal experience and I think you'd be happy with a rotary. Good luck, Diesel Rider

Replacing the 3 phase motors with single phase motors is about the worst step to take. Far better to find a converter, or if possible get 3 phase service to the house & shop. Then you can get 3 phase air conditioning, washer, dryer, range, and many other things that will please you with their efficiency.

Few places in America will allow 3 phase power to a home. This is considered industrial power and often only is supplied to commerically zoned areas. In my area most home developments do not have 3 phase in the grid. ** The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, don't fail to listen to suggestions. -randy- Modified by RKimball at Sun, Oct 19, 2003, 20:24:18
