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
What else can I help you with?
Motor 1 hp equals how many amps?
hp= 745.699872so if the rated voltage is 220 so 745.699872 /220=3.389 A
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
How many amps does 1 phase 220volt 7.5 HP draw?
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
1 hp compressor amp?
To answer this question the voltage of the compressor is needed.
Will a motor that has 220 volts and 7 amps have enough power to equal 1 hp?
Yes! One HP equals 749 watts. W = V . I 220 . 7 = 2.056 In reality, with 7 amps in 220 v you have more than 2 HP. By Nonô - BRAZIL Yes! One HP equals 749 watts. If you have 7 amps on 220 v, as watt = volts . amps, 220 . 7 = 1540 watts 1540 / 7498 = 2.056 HP. You have more than 2 hp. By Nonô - BRAZIL
What is the resistance of an object that uses 220 volts and draws 1 amp?
The formula you are looking for is R = E/I.
What fractional HP is a 3 amp motor?
To calculate the HP of a motor, you can use the formula: HP = (Watts x Efficiency) / 746 Where Efficiency is a typical value between 0.7 and 0.9. For a 3 amp motor, you will need to know the voltage to calculate the wattage and then convert it to HP using the formula above.
1 hp how many cc?
These things aren't related like that. CC means cubic centimeters. Its how much displacement the engine has. HP means horsepower. example: 2.3L 4 cylinder engines can make anywhere from 90 HP to 220 HP...
How many amps does a Hayward 1 Hp Pool Pump Motor use?
1 HP = 745.70 wattsPower (watts) = Current (amps) x VoltsSo if you use a 110 volt system, amps = 745.7/110 = 6.779 ampsIf you use a 220 volt system, amps = 745.7/220 = 3.389 ampsFor a 12 volt system, amps = 745.7/12 = 62.142 amps
How many amp does a three phase 430 volts 1 hp motor draws?
About 3 amps, maybe slightly less.
How many amp in 1.25 hp?
To answer this question a voltage is needed. 1 HP = 746 Watts. Amps = Watts/Volts.
How many watts are in 220 amps?
This is 220 volts AC, I assume. 10 x 220 = 2.2kVA of power. The real power will depend on the power factor. Take the power factor times 2,200 to find the watts.
