The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps
A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
5000 volt
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
It would probably be 20-30 amps. <<>> The electrical code book states a value of 18.7amps for a 3HP 208 volt motor. If the nameplate data is available it is always best to use it when calculating wire size and overload protection for the motor.
Yes, but the motor's horsepower rating will not be reached.

5000 volt
317.025280 KILOWATTS = 317,025.28 WATTS
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
20 HP Three phase 360 volt what is the amps
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
You can use an insulation rating 5000 volt to run 4160 volt supply.
Yes, but the motor's horsepower rating will not be reached.

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.
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
Use a transformer.
