    2 motors - 1 VFD

    Hello Everyone,
    I am building a CNC machine. It is not usual/well known machine and I need 2 motors running with exactly the same speed and torque but in opposite direction to each other.
    Is it possible in any way to run 2 3phase motors fed from one VFD but in opposite direction to each other?
    With steppers it quit easy - just connect 2 motors to the same controller and reverse wires of one motor.
    It is my understanding it would not be possible with 3 phase motors. or is it?
    I would very much appreciate any suggestion to solve it.

    Thank you very much in advance!
Working...
