First you have to have three phase power coming in. 3 phase are three hot wires working together on a syne wave. If you have 3 phase coming in, hook the three hot wires into the compresser, if it runs backwards, trade places with two of the wire and let the third one alone and you should be running.
This is a voltage drop question. The voltage and HP or amperage of the compressor has to be stated along with whether the compressor is single phase or three phase.
If you are referring to an air compressor motor then yes. A single phase and three phase motor can be interchanged. They have to have the same horsepower though because the compressor manufacturer has calculated the needed HP to turn the compressor over. You may need to rewire for the single phase motor unless the single phase voltage is the same as what the three phase voltage was. If this is the case just use two legs of the three phase voltage supply. The overload protection will have to be changed to reflect the higher current used by the single phase motor.
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
Allow 7 amps per HP for a 240 v single-phase supply, that's 70 amps for 10 HP. On 220v 3-phase the current would be 44 amps. On 440 v 3-phase the current is 22 amps.
To answer this question the voltage of the compressor is needed.
7.5
Horse power is horse power, regardless of what voltages and currents are used. 5 HP single phase is equal to 5 HP 3 phase.
You don't, single phase motors that size are wired to 240 volt circuits, to put a 10 hp single phase motor on 440 volt would require a transformer and numerous other components. Use a 3 phase motor they are significantly cheaper to purchase.
A 10 HP motor on a 120/208 4-Wire Wye installation should draw about 30 Amperes.
No.

Probably. 5 hp. is 5 hp., regardless of the phases that drive it. But for practical implementation, you will see following problems: 1] Single phase motor will demand for neutral connection. 2] As entire current for 5HP load will be now on single phase, your conductor will be loaded 1.732 times its rated load ( for 3 phase motor design) Hence it may call for increase in conductor cross section. 3] As entire 5 HP load will be now on single phase, your loading will be unbalanced. Single phase equivalent motor will be of slightly bigger dimension hence mounting arrangement will have to be suitably modified.
The formula you are looking for is I = W/E. I = 746/220 = 3.39 amps <<>> Rule of thumb Current (Amps) of Single phase 240Vac motors = HP x 5 For Single phase 220Vac use Rule of Thumb and add 0.5A Current (Amps) of three phase 400Vac motors = HP x 1.5 Good for single phase from fractional HP values up to 7.5 HP. Good for three phase HP values up to 30 HP
20 HP Three phase 360 volt what is the amps
10 hp is its output power. To determine its inputpower, you need to know its efficiency, then use the following equation:efficiency = (output power)/(input power)You will first have to convert 10 hp into watts. There are 746 W in one horsepower.
Up to about 40 HP.
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
To show the difference in kWs a 10 HP motor will be used. The single phase current for a 10 HP motor is listed as 50 amps at 230 volts. The formula for kWs single phase is I x E x pf/1000 = 50 x 230 x .9/1000 = 10350/1000 = 10.35 kw. The three phase current for a 10 HP motor is listed as 28 amps at 230 volts. The formula for kWs three phase is I x E x 1.73 x pf/1000 = 28 x 230 x 1.73 x .9/1000 = 10027/1000 = 10.02 kWs.

I am assuming we are taking 240 volt single phase to 240 volt 3 phase, it can be done. Two ways, you can use a variable frequency drive, this drive would be sized at twice the load. So if you have a 5 hp 3ph motor you would need a 10 hp VFD. You can also use a rotary phase converter, it would also be sized at twice your attached load. A rotary phase converter can be built from a standard 3 phase motor or there are companies who manufactuer them.
Yes, most large motors are three phase. Usually single phase motors only go up to 10 HP. Larger than this and the wire size and contactors used to control the motors becomes extreme. For example a single phase 10 HP motor on 115 volts draws 100 amps. The same single phase motor on 230 volts draws 50 amps. The same 10 HP motor on three phase system draws the following amperage; 230 volts is a 28 amp draw, 460 volts is a 14 amp draw and 575 volts is a 11 amp draw. As you can see the higher the voltage becomes, the smaller the wire feeder size is needed and much smaller size contactor can be used to control the motor.
A 6 kVA generator could supply a 6 HP compressor motor.
