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, 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.

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.
