Best Answer

it uses 45A at 415V in Pakistan and starting current might be near 60A.

The equation you are looking for is, Amperage when horsepower is shown; HP x 746/1.73 x V x %eff x pf. As you can see that an answer can not be given without the voltage of the motor being stated. Once you have the voltage use the formula. Use .89.5 for the % eff of a standard 25 HP motor and .89 for the power factor of a standard 25 HP motor. Using the above answer's voltage, the motors amperage equals 32 amps. A motors starting current can reach 300% on start up. The starting current can reach 96 amps instantaneous until the motor amperage drops to its run amperage.

How many amps does 500kw at 600volt 3 phase use?

481 amps if the load has a power factor of 1, but if the power factor is less than one (e.g. if it's a motor) you also have to divide by the power factor.


How do you calculate 3 phase power for a motor that draws 22 amps per leg it is a 480 3 phase motor do you use 480 x 22 or 277 x 22?

1.73*480*22


How many amps is a 380 volt 0.18 kw 3 phase electric motor?

The formula you are looking for is Amps = kW x 1000/1.73 x E x pf. Use .84 for a power factor value.


What circuit you can use to run three phase motor?

It must be a three phase supply service to run a three phase motor.


How many amp does a 3 phase 208 voltage motor use?

It depends on how powerful the motor is, and what type of load it is driving.


What size feeder and breaker is needed for a 15 ton AC - 3 phase at 440 Volts?

Would have to know the current rating of the motor or each of the phases on the motor when running. 3 Phase motors usually use mucvh less current than their single phase counterparts. My son has a lot of 3 phase equipment in his shop and most of them run under 5 amps per leg. But you really need those specs from the motor.


How do you convert a 0.37kw 4 pole 3 phase motor to single phase?

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.


Can you use 2.5sqmm wire for a 7.5 kw motor?

No you can not it's 31 amps


How many amps for 430kW at 208V?

Because the voltage is 208 I will assume that it is the 3 phase formula you are looking for. Amps = Kw (430) x 1000/1.73 x Volts (208) x pf. Unless you know the pf use .9 and you won't be to far off in the calculation. Same formula for single phase but don't use 1.73.

How different is the horsepower used by an air conditioner unit if it runs on either single phase or three phase ac?

There is no difference in horsepower. The manufacturer builds the air conditioner. Engineers calculate and tell the manufacturer how much power is going to be required to make it operate. Smaller units will probably use lower voltage with lower horsepower to operate efficiently. The bigger the unit will take higher horsepower to operate. There comes a point when single phase, low voltage use will not work due to the unavailability of high horsepower, low voltage motors. At this point three phase systems are used with higher voltages to operate the motors. Examples of a 10 HP motor at different voltages. Single phase - 115 volts 100 amps, 230 volts 50 amps. Three phase same HP - 200 volts 32.2, 230 volts 28, 460 volts 14 and 575 volts 11 amps. As you can see if the air conditioner needs a 10 HP motor at single phase 115 volts, a feeder supply of 100 amps would be needed. This compared to the same air conditioner using a three phase 575 volt system which draws 11 amps.


What wire size is needed for 415 volt 20hp compressor motor?

A motor can be reckoned at 1.6 kVA per horse-power, so on a 415 v 3-phase suppy the current for 20 HP would be 45 amps. For continuous use the wire size should be 25 mm2
