3 Phase Generator Circuit

(1/4) > >>

Windows9Professional:
For testing of an three phase induction motor I would need a powerful three phase generator (120° phase shifted).

Is there a simple circuit for this job?

I was thinking of an SPWM sine generator with just 3 lookup-tables for sinewaves which are simply 120° out of phase, but that seems a bit of overkill.   

Benta:
How powerful? Voltage? etc., etc. My crystal ball is in the workshop.

Zero999:
I wouldn't bother designing one, unless it was for purely educational purposes. What you're after is known as a variable frequency drive and is an off the shelf module.

Windows9Professional:
Since I only want to experiment with (self made) induction motors I better keep the voltage down for now and after some research it seems to me that Variable Frequency Drives are mainly available for mains voltages, for which I could also use the three phase mains here in Europe, but ist far too dangerous.

I'm looking for an Low Voltage, three phase generator with reasonable current capability or for an DIY alternative

Zero999:
Then use a VFD with transformers connected to the output?
