3 phase 220v AC

  • This may be a bit of a stretch topic wise but electrons are electrons......

    I have acquired a used Stenhoj auto lift.  It is powered by a (class A or B) 3 phase 220v 2.2 KW 3 HP AC motor.  To run this in my garage I will need to purchase a single phase to three phase rotary converter.

    The question is how big or what HP size rotary converter should I get for the 3 HP motor?  I have been told by a supplier that I should step up to a 5 HP rotary converter.  Is this necessary as these units are very expensive?

  • Man, I've got no idea. Maybe hit up a hardware store for help? Anybody else have some input?
  • Somewhat mentioned in your previous thread here.

    I don't have a good answer, though.  You might contact Stenhoj and see what they recommend.

    5 HP would undoubtedly be better, but it might be a situation where 3 HP is just fine, or where 3 HP burns out in six months and you have to buy another 3 HP, which is probably more $$$ than buying the 5 HP one time.

    Hope This Helps!!!

    Anyone else have suggestions?

    I have been told by a supplier that I should step up to a 5 HP rotary converter.

    Unless you think the supplier is untrustworthy, in which case you should find another supplier, I'd say you've got your answer.
