The table will vary from edition to edition. In the 2005 NEC, it is table 430.250. Note that these are only typical values, and will vary from motor to motor.
If the motor voltage is 240 you can hook 240 to any two motor leads then put a switch and a capasitor in series from one leg to the other motor lead.once motor starts open switch,the motor will be rated at 58% about 8.7 hp.Another way to do this is if you have another 3 phase motor the same size or larger ,hookup 240 to extra motor any two leads hook leads from motor to air comp start contactor.Turn shaft on extra by hand it will srart which will make a third leg "3 phase" I know this is working on a three phase wheel balencer for the last 8 years i don't believe i would want to "hand spin" a motor on a compressor... a bit hazardous! another factor here is the direction of rotation as most compressors are sensitive to this. the starting current on a motor of this size and the service it is in quite large, the best bet would be to find a replacement single phase (220V.) motor (matching rotation, speed and starting torque). one could always use a rotary phase converter, but this is a spendy and involved way to do the job.
Ceiling fans typically use AC induction motors because they are reliable, cost-effective, and efficient for converting electrical energy into rotational motion. These motors are designed to operate continuously for long durations while maintaining a consistent speed.
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
A pub table set is typically a high top table and stools like you would find in a bar. Depending on the brand and style of pub table, the can include from two to four chairs.
Stop being lazy it would take 2 seconds to look at the periodic table and find out.
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
i have no clue, why the fu** would anyone know this.
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
Go to the website of a motor starter manufacture, such as 'Square D'.
One And a Half Horse Power Obviously.
Only if you want to damage it. "277" Volt 3-phase will usually mean 277 from each phase to neutral, and 480 from phase to phase. By "230 3-phase", you likely mean 120 phase-to-neutral, and 208 phase-to-phase. If you really mean 230, then you are probably NOT talking about a three phase motor.
If your three phase motor runs backward, you have two phases swapped. double check a, b and c phase to find which ones are misplaced.

Of course, but it will change all parameters (HP, torque etc.) The problem is someone would have to redesign of that motor, size of coils in field winding according to new voltage, speed and HP ratings. Basically, is not worth it.
The primary disadvantage of the three phase induction motor is that speed control is a challenge. But new technology in the form of VFDs (variable speed drives) is now rectifying this situation very effectively. Another disadvantage is that single phase power is common while three phase power is less commonly available.

To find the amperage of a three phase motor, the following equation needs to be used. Amps = HP x 746/1.73 x Volts x % efficiency x power factor. once all of the values are added you can find the amperage of any Horsepower motor at any three phase voltage. 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.
