I have two 6000 watt generators that are bi-phase and want to run a 5hp motor that is 220v / 3 phase. Is it possible? How would the wiring go? I'm in Mexico and can't find a rental... well I found varios but no one that can hook up my motor.

No, your plan won't work.

Chad, you can produce what they call a WILD 3rd leg with the use of an electric motor and some capacitors
