4 Hp Electric Motor Amp Draw
P w 735 49875.
4 hp electric motor amp draw. Put on rubber gloves to protect you from an accidental electric shock. For example let s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90 efficiency. Amps amount of the rate of flow of electricity whereas horsepower measurement of work divided by time. Metric horsepower to watts.
The conversion from amps a measure of electric current to horsepower a measure of power output by a motor can be done using a fairly simple formula. P w 746 10hp 7460 w. One metric horsepower is equal to 735 49875 watts. So the power conversion of horsepower to watts is given by.
Thus horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor divided by 746. 460 volts motor 3 phase. Example if you have 100 hp multiply by 746 and you get 74600. 230 volts motor single phase.
Amperes amps and horsepower hp are the electric motor s rating methods. Locate the terminals on the ac motor. Amps to hp calculator. 1 hp 745 7 w.
As a rules of thumb amps horsepower rating can be estimated to. How to convert hp to amp ac 3 phases in only 3 step. 115 volts motor single phase. 230 volts motor 3 phase.
This motor full load amperage fla calculator allows you to calculate the full load current of the ac electric motor. Note that an electric motor is an inductive load. Run your ac motor otherwise you can t check the amperage draw. Here are the typical full load amps fla for 220vac and 120vac 1 phase 60hz electric motors for 230vac 1 phase 60hz electric motors divide the following values by 2.
So the power conversion of horsepower to watts is given by. Horsepower i a v v η pf 746. 1 hp m 735 49875 w. Amps hp 746 v η pf thus the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor.
1 hp e 746 w. Select the number of phases from the drop down list. Convert 10 hp to watts. With low power factor it pulls lot of amps producing little hp output.
Multiply the ac voltage by the motor efficiency the power factor and the square root of 3. P w 746 p hp example. Multiply hp horsepower by 746.
