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.

Up to how much HP are single phase motors maufactured?
Horse power is horse power, regardless of what voltages and currents are used. 5 HP single phase is equal to 5 HP 3 phase.
Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
How much more efficient is a 2 hp 240 v 3 phase motor compared to a 120 v single phase 2 hp motor?
I would guess it would use a third less than a single phase motor. The voltage differences don't save but 3 phase does. A 3 phase motor also starts easier.
What fractional HP is a 3 amp motor?
It could be a single phase 1/4 HP motor running on 230 volts AC.
Can a 240 volt single phase motor be supplied with one phase until the other phase is closed without harming the motor?
Not a good idea. Use a double pole single throw switch to start and stop the motor if motor HP is small. Use a motor contactor on larger HP motors.
Will a 10 hp 220 volt motor draw large amounts of electricity?
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
What is max single phase hp as per nec?
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
1 hp compressor amp?
To answer this question the voltage of the compressor is needed.

Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
What value of capacitor for 2hp acu compressor?
acu compressor motor window type aircon 45 uf capacitor for 2.5 hp compressor 50 uf for 3 ton acu 60 uf for 1.5 hp compressor 35 uf
If 1 hp and 220 v find amp?
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
How do you figure out how many kilowatts a 10 hp 3 phase motor will use?
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.
What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?
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.
What is the Amperage of a 20 HP motor at 380 VAC 3 phase 50 Hertz?
20 HP Three phase 360 volt what is the amps
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
Are all large motors three-phase?
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.
