For the same power - Watts - you need to run twice as many amps at 220V than at 440V.
For the same load, it'll pull half the amps at 220V than it did on 440V
It will not work at all.
My first thought is this is probably a corner grounded delta system, but I'm confused by your voltages. If this was a 460v (L-L voltage) ungrounded or corner grounded system, the phase to ground voltage is meaningless, but the phase to phas voltage will be 460v all around the delta. If you have a 460v system and you're only seeing 230v, there's something wrong.
Wiring a 9-lead motor for 460V operation involves configuring the motor leads according to the desired connection type, typically either wye (Y) or delta (Δ). For 460V, you would typically connect the leads in a delta configuration, where each of the three phases connects to two of the motor's leads. Ensure that the motor's voltage rating matches the supply voltage, and always follow the manufacturer's wiring diagram for specific lead connections. Additionally, ensure proper safety protocols are followed when working with high voltage systems.
First of all, a 150 HP 460V 3-phase motor only draws around 170A, so two of them would only draw 340A, not 800. 340A at 460V equals almost 300,000 watts (or 300kw), and the generator would need to be sized a little bigger than this to start such big motors.
Primary : 4 Secondary : 3/0 <<>> To answer this question correctly a voltage must be stated.

Yes, as long as you use only one phase of the 3 phase system. If R & Y gives 460 volts, use R & Y. This not a good approach though.
It will not work at all.
Depending on model and condition anywhere from $1500-850.
The the supply stays within +/- 5% of what the motor is rated for, you can do this.

You can use a voltage converter to step down the 460V 3 phase motor to match the 380V 50Hz supply. Make sure the converter can handle the motor's current requirements. It's also advisable to consult with an electrician to ensure safe and proper installation.

yes can run but motor only delivers 90%rated power because v/f less by 10%

In the United States, 480 Volts (AC) is a nominal system voltage before it is distributed to the device being powered. Line losses (measured in volts) occur throughout the distribution system due to current passing through wires and devices which have a resistance. Manufacturers of end use devices, such as motors, take this into account and list their devices as 460 volt devices. So, what this means is that you will see transformers and circuit breakers with nameplates at 480 Volts (AC), and motor nameplates at 460 Volts (AC). Older 3-phase motors may actually have nameplates for 440 Volts, but all new motors in this voltage range would be listed as 460 Volt motors.
No, connecting a 460V machine to a 550V power supply is not advisable, as the higher voltage can damage the machine and create safety hazards. Most equipment is designed to operate within a specific voltage range, and exceeding that can lead to overheating, insulation failure, or permanent damage. It's essential to use power supplies that match the voltage requirements of the equipment to ensure safe and reliable operation. Always consult the manufacturer's specifications before making any connections.
