First of all, your power source must be 3-phase if you want to run the motor, then you need a step-down 3-phase transformer to give 220v 3-phase output.
575 vac used to be a very common voltage in textile mills and there are Transformers to do what you want. So your answer is use a transformer.
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
Not advisable, the voltage differential is too great.
Yes, but you would not want to. 575V is simply 115V run through a 1:5 transformer. (5x 115) 115V @ 20A AC = 575V @ 4A AC Usually the devices (welders) on the 575V side are running 10 or 15A, so: 575A @ 15A AC = 120V @ 75A (A 75A breaker for home use isn't common) 575 volts is a 3 phase voltage. The actual 3 phase voltage is 600/347 to ground. If you have a device that requires 600 volts check to see if it is single phase or three phase. For 3 phase 600/347 you will need a separate service.
Three phase or two phase? Three phase requires three large wires for the current needed
It must be a three phase supply service to run a three phase motor.
You can get a buck / boost transformer which will step down the voltage. What will be important is phase supply.
No. That would be a single phase motor.
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
Yes, it will just run slower than rpm indicated on nameplate
Short answer: No. (unless you like ruining motors) Longer answer: Not really, but there are some motors that can be re-wired so that instead of 440v they will run on 220v. However, this is not that common. Conclusion: Check the motor to see if it is dual-voltage on it's nameplate. If it is, you can re-connect it to work on 220v. If it is NOT a dual-voltage motor, you will absolutely ruin it if you connect it to 220v.

Synchronous motor
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
