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

How will work motor 460V 3ph 60Hz at 380V 3ph 50Hz power net?
It will not work at all.
Why does one line of 3 phase 480v show 0 volts and the other 2 have 480?
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.
What generator size for twin 150 hp 480 3 phase motors 800 amps for a tire shredder.?
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.
Wire size for a 15 KVA transformer?
Primary : 4 Secondary : 3/0 <<>> To answer this question correctly a voltage must be stated.
Can a 3 phase 415V- 1000V step up transformer operate correctly from 460V Ac supply without causing damage?
That's an 11% overvoltage (460/415), so this may be reaching the design limits of the transformer. If the system is actually run hot (say 105% of 460, or 480v), then I'd say no, unless specifically stated in test reports or design criteria. You should ask the manufacturer to be sure.
What is the rated current for 3phase 50 hp 460v?
60.4
Can you wire a 460V 1PH motor to any 460V 3PH system?
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.
Can you run a 460v 60hz motor to a 480v supply?
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
How will work motor 460V 3ph 60Hz at 380V 3ph 50Hz power net?
It will not work at all.
How much is a smith and Wesson 460V revolver worth?
Depending on model and condition anywhere from $1500-850.

Can you run a 460v 60hz motor to a 400v supply?
yes can run but motor only delivers 90%rated power because v/f less by 10%

How do you explain the difference in 440V 460V and 480V?
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.
Can a DC to AC inverter with 230 VAC output voltage be connected to an AC to AC inverter to get 3 phase 460 VAC output voltage from a 720 VDC battery pack at 60 amps?
It would make no sense even if you could find a DC-AC inverter with an input voltage of 720V. The efficiency would be horrible and the bulk of the equipment would be impractical. The voltage your motor expects is 460 VRMS. This translates to a peak voltage of 650V (1300V peak-to-peak). Your battery pack, switched through an H-bridge of IGBT's using a PWM scheme could directly feed the motor. This is the best method available, but the design would not be trivial. Possibly, you could ditch the DC-AC inverter and use just a 460V variable-speed drive with 460V input and 460V output. Bypass the input rectifiers on the drive and use your batteries DC output directly to power it. It's a possibility anyway. You realize, of course, that you are dealing with voltage and power levels that can be fatal, right? Be careful.
