can i hook up a three phase 460 volt motor up to 480 volt?

if the voltage rating of your motor is 460, you can really hook up to a 480 volts electric s=poer source. the maximum your motor can hanmdle is 460 = 10% of 460 whixh is 506 volts

Normally this is a "Restive" not voltage question/answer, and the proper neutral to ground = 2 Megg ohms (min.) this being incorporated in a residential application.\nHigher voltage in let us say a 3-phase utilization this # is on the low side. (assuming a.c. source. d.c. is a completely different animal!

I seriously doubt you have a 50 HP motor!  That is industrial size, and I wouldn't expect a question like that here.\n\nWhat voltage?  A 3-phase 50HP 230V motor is 130 amps!  There is no single-phase motor that big.  If you really have this, get an electrician to install it.

Just buy the plugpack.\n\nIf you want more amps, or variable volts, be specific.

yes, it is a step-up circuit.\nYou can get many volts if you know what you are doing.

If one of the three phases is lost, the current drawn by other two phases would rise and following consequences would follow:\n1. If motor was not fully loaded and current drawn by remaining two phases (after loss of one phase) of motor are less than its rated current, motor would continue to run.\n2. Motor would get heated and thermal over load should protect it.\n3. If phase failure or negative sequence or unbalance protection was provided motor would be stopped by activitation of these devices.\n4. If neither of above protection is provided and motor is loaded in such a way that it results in over heating, motor may burn if temperature rise is more than temperature which its insulation can withstand. There are different limits for different class of insulation.

No, 9 V. is standard, if you need more, you have two options:\n1) Made a special circuit, to get more than 9 V from a 12 V battery.\n2) Build a battery according to your specifications.

Just use four 12v car batteries in series = 48v, you can always hook them up to some renewable or rechargable source.

I would just run it at 60 Hz. Output rpm will be 20% higher. \n\nAlternately, you could get a 400V VFD and set it's output to 50 Hz.

No. particularly if all six macchines are to be used simultaneously.  Use a 460-480V power source, with distribution via a "Square D" power-sensing circuit distributor.

The deciding factor here would be the Utility Company Service Entrance. THAT cannot be rewired by you! The other two points ( Low side of transformer and Motor Windings) can easily be configured either way by simply rewiring the 3 windings on the motor, and the 3 windings on the output of the transformer.\n\nOptimum efficiency will be DELTA-DELTA-DELTA or STAR-STAR-STAR...Either way no 'ground loops' to cause loss.

You cannot do this directly. Assuming you are talking about a motor, It may be possible to get the motor to turn using a capacitor but you will not get the rated torque (turning force). I'm sure there is plenty 3 phase theory on the internet if you want to see why they are so different\n\nOne way it can be done is by using an inverter that takes single phase input (providing the voltage you require is not higher than the voltage you have or you will then need a transformer as well). The inverter gives you the added value of being able to vary the speed but it may be cheaper to simply buy a single phase motor. As you didn't actually specify the device to be motor, be aware that VSD inverters may not work on other equipment.\n\nYou need to be wary of the size of the device you are trying to operate. Often 3 phase is used for higher powered devices that becomes in-practical to try and run on single phase anyway.

I don't think you can do that. you need the number of amps and the power factor for that device.

One word of caution! The generators must be in phase for you to connect them in series and that will be nearly impossible to find in a small, commercial generator.  Without very tight control over each generators sync with the other, you could end up with anything from approx. double one generators voltage to the voltage of one generator alone and most likely fluctuating in between.  This will reek havoc on many things you may want to run with it and destroy lots of others outright. It could be done with the right electronics, engine and generator modifications and know how, but it would also be very expensive and time consuming.  If you need a 480V genny, it's much easier to find a used industrial engine welder or scavange one for its transformer.

The motor is designed for 415V 3ph which produces a magnetic flux which in-turn provides torque and horse power. By reducing the voltage you reduce the capability of the motor, or reduce the horse power. \n\nTo have an equilvalent HP motor at 240V 3ph you essentially must rewire the stator and armature windings.\n\nWhat you can do is use a Auto-transformer and step up the 240V 3ph to get 415V 3ph out. But the ampacity is reduced, Power in = Power out (watts). This may be sufficient for your needs.

I am unaware of any 2-phase electrical systems.  \n \nTo get 3-phase power from a single phase (as in your home electrical) system you need to have a single phase motor run a 3-phase generator.
