Title: AC Inverter
Post by: MC on July 26, 2011, 01:38:11 AM

Hi

If I have an AC inverter output of 3x 0-32VAc how can I drive a 3 phase motor having a rating of 230 or 415V

Help would be appreciated

Using a large transformer. A really large transformer.
Given that, you will have to be drawing around 5 amps dc just to get half an amp at high voltage given that you have a perfectly efficient system. (not even close)
So saying you can come up with all that it's just a matter of looking up what wires go where.

A far more practical approach is to find how low of a voltage your motors can run at and still give results.
