    Re: Running a 3-phase machine on 220 via a VFD

    Phase to neutral voltage is 230 V
    Phase to Phase voltage is 420 V so double the rated voltage will cause some issues :-)

    Hi Plunger

    We use 525 V / 550 and 690 V three phase motors in the mining sector.


    Higher voltage means less current and therefore smaller cable for the same power.

    Re: Running a 3-phase machine on 220 via a VFD

    Not if the motor has a VSD

    With a VSD the motor can always produce it's rated Torque.

    At half the speed it will only produce half its power as power is a factor of speed and torque.

    Not always the case .
