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 a 30HP motor use hooked to 480v 3 pH 60Hz line?
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
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 3 hp 240 volt motor use?
AWG #10 copper on a 30 amp breaker.
How many output amps is a 45 kva transformer?
There is not enough information provided to answer. KVA is short for "Kilo Volt Amperes". That is, thousands of Volt Amps. In order to determine how many Amperes are flowing, you must know at what voltage it is operating. Amperes = 45,000 ÷ volts Bill Slugg
What size of wire use and breaker for a 30 hp 220 volt 3 phase compressor?
Wire size calculations and breaker sizing are based on the motors amperage. If the amperage is not known the electrical code book rating are used by electricians. The book states that a three phase 30 HP motor draws 80 amps. An 80 amp motor needs a conductor rated at 100 amps. A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 115 amps respectively. Non time delay fuses rated at 225 amps, time delay fused rated at 125 amps or a breaker rated at 200 amps. These figures can probably be reduced if the actual motors amperage rating is used in the calculation.
How many amps does a 3 phase 22kw motor use?
22 kw motor how much takes ampares with load
How many amps does a 30HP motor use hooked to 480v 3 pH 60Hz line?
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
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 is the running amps of a 45 kW motor?
To determine the running amps of a 45 kW motor, you would need to know the voltage at which it operates. You can use the formula: Amps = (kW x 1000) / (Volts x power factor). Once you have the voltage and power factor information, you can plug them into the formula to calculate the running amps.
What size time delay fuse do you use on a 40 hp 230 volt 3 phase motor?
The electrical code book states that a 40 HP 230 volt three phase motor draws 104 amps. For that motor the wire must be rated for 131 amps, Non time delay fuses at 300 amps, time delay fuses at 175 amps or a 250 amp circuit breaker. When calculating wire sizes and motor protection the motor's full load amperage should be taken from the motor's nameplate.
What size of circuit breaker do you use for 25amperes induction motor?
Read the specification plate on the motor to determine the amount of current that the motor uses, as well as the voltage and phase. Most likely, it will be a 3 phase motor, so you can't simply connect it to your house wiring, but without sufficient information, it is impossible to tell you all of the specifics. <<>> The code book rates the amperage of a three phase 40 HP motor by different voltages. at 200 volts - 120 amps, 230 volts - 104 amps, 460 volts - 52 amps and 575 volts - 52 amps. A breaker for a motor has to be sized to 250% of the motors full load amps. Also the wire size for a motor has to be 125% of the motor full load amps.
18kW motor will take how many amps?
To calculate the amps drawn by an 18kW motor, you can use the formula: Amps = Power (Watts) / Voltage (Volts). Assuming a standard voltage of 120V, the motor would draw approximately 150Amps. Note that actual amps will depend on the specific voltage of the motor.
How many amps does a 3 phase 20 hp motor use?
30 HP at 480 (3 Phase) - 746 multiplied by 30 = 22380 22380 divided by 480 (3 Phase) = 46.5 46.5 divided by 1.73 = 29.5AMPS Motor speed and efficiency may change the actual result. Always refer to the name plate data
How many amps does a one horse power motor draw?
depends what the source voltage isone horsepower equals to 746watts (assuming 100% efficiency)746 watts divided by voltage source equals current (amps)AnswerIn countries, such as the USA, where the horsepower is still used as a means of measuring power, it is always used to measure the output power of a motor.So, in order to determine the current drawn by the motor, you will first need to find out its input power. The input power is the output power divided by the machine's efficiency. Once you know its input power, then you can find its current by dividing the input power by the supply voltage. In practise, you will need to use a wattmeter to determine its input power.
How many amps does a 50 horse power electric motor use?
Need to know the voltage of the motor.
