    Anyone interested in a RPC build?

    FINALLY getting to start building the Rotary Phase Converter tonight. Just mounting the components in the enclosure. Had not planned on documenting this but I plan on posting some photos as I go. Just wondering if anyone else is considering building one?.

    Being my first I am certainly no expert. Just stumbling through this but I think I finally have a grip on it how it works. I have been looking at the drawing for a couple of weeks now.

    For those unfamiliar with the term, it is method of generating 3 phase power from standard single phase house hold current using a 3 phase 'idler' motor to generate the 3rd leg of electricity. Well something like that anyway.

    Photos to come. To tired to walk down the stairs to the Lab tonight.
    God grant me the senility to forget the people I never liked anyway,
    the good fortune to run into the ones I do,
    and the eyesight to tell the difference.

    Document away! I don't plan to make one in the foreseeable future, but I still would like to see the details.

    That would be great information for a guy to have in his back pocket in case he runs across what he thinks is a good deal on a three phase machine. knowing how much trouble it is and how much it cost would be necessary to know if it is really a good deal or not.

    I'd be interested, too. I'm having a heck of a time wrapping my head around it and i'd like to know what kind of draw it has...

    Does the current draw on the line equal a combined total of amperage? I mean ... if it's 5a per leg, is it 7.5a per leg on the 220? That's the part i am still confused about (obviously)

    Absolutely interested. I was going to ask you how you do this and where you got the plans and components.

    I really like the threads that show progress of a project. I always learn something or get an idea from reading.

    What, not EVERYONE has 3-phase in their workshops



    I'd be interested in a RPC build, your rebuild threads are always interesting and I usually learn something new, so please do!!

    OK, guess I better get in gear today. Made a list of wire I need and expect to pick that up today and start wiring it up tonight. Will just start a new thread on this.

    Jason, not sure I understand what your asking. But if you have a motor that draws 5 amps and you can rewire it 220v it then draws 2.5 amp on 220v. It's all about Ohms law.

    Hey Jeff,

    I'm glad you are going to do this. I am not ready to put a RPC together now, but I will in the (hopefully) near future! Thanks!
