    Hi,


    Just wondering how could I make a Three Phase Power Generator/converter from single phase for Bench experiment purpose..

    Cheers,

    Google "rotary phase converter". You'll find many plans to build one or where to buy one.

    Besides buying, many car alternators with its diode pack removed will give you 3 phase AC.

    You will need a motor to turn the alternator (You wont get free energy).

    This is known as a rotary phase converter, as Jaguarjoe mentioned.

    Be sure to to spend some time on the motor drive circuit to get a steady output at the desired frequency from the alternator.

    If you need only a few mA, you may want to check out 3-phase micro-motor drivers.

    Hard-drives often use 3-phase for their motors, so you could extract the driver circuit from a discarded cd-rom or hard-drive.

    For more umph, buying a rotary-phase-converter may be the way to go.
