    Electrical. 240 to 3 phase invertor costs/advise

    Hi all, wondering if anyone here is in the know to advise.

    I'd love to add some timber working machinery, but they are mainly 3phase.

    3 phase I imagine will be prohibitive. What are the inverters like?

    Costs?

    I guess drawing of machines come into it and I don't know. Might be able to find out if its pertinent.

    Cheers, John

    The best option may be to fit a single phase motor. If you cannot fit a big enough single phase motor because of power you need to run 3 phase anyway. The inverter will not get you around this problem.
    There are only three types of people in this world. Those that can count, and those that can't!

    All depends on the electric motor size. A 2 HP single to three phase inverter is not that expensive. With some creative wiring one could be used for a few different machines Additional would be just to make some leads unplug the saw plug in the sander etc
    Plus of course you get great speed control plus motor protection .

    Thanks. I need to do some more thinking, sounds expensive either way.

    Depends on motor sizes and age of motors can come into it. there are some nasty VSDs (variable speed drives) on the market as well
