Note: The AC three-phase current I (A) can be measured in phase side At the same time Line current, I (A) is equal to 746 times of the power P (HP) in HP divided by root three times of the voltage V (V) in Amps. Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase it takes only 3.8 Amps. Example, if you have 100 hp multiply by 746 and you get 74600. Peak HP should not be used in reality since it is mostly a marketing gimmick. 1 hp(E) = 746 W. So the power conversion of horsepower to watts is given by: P (W) = 746 ⋅ P (hp) Example. Amp to Hp calculation formula, DC, AC, 3 phase, 2 phase, 1 phase: I DC =Direct current. Calculate Horsepower from Full Load Amps. One Amps is equal to One coulomb per second. Step 2: Multiply the AC voltage by the motor efficiency, the power factor and the square root of 3. Also 5 HP three-phase motor takes 6.4 Amps. HP to Amps Formula. The phase current in amps I (A) = 746 x P (HP) / (3 x V (V) x pf) in Amps. So the adjusted thrust horsepower formula goes as follows: Horsepower (hp) = current draw (amps) x voltage x efficiency x power factor/764 In practically the current rating may change and which is based in the manufactured standard as well as the what grade copper they are using to winding the motor. Ampere is an SI unit of measurement of electric current. Note: Most motors are rated using "Peak HP consumed" which is much higher than "true continuous HP". Amps to HP Calculator. One Amps is equal to One coulomb per second. Two Phase, 4 Wire AC Calculations The following formula is used to calculate the total horsepower from amps. For example, if the motor is 220Vac, it has an efficiency of 80% and the power factor is 0.9, it must Multiply 220Vdc by 0.8 … Horsepower (hp) = current draw (amps) x voltage x efficiency x power factor/764 Assume 85% efficiency for the electric motor and 0.9 power factor (typical value). Motor Current Rating Chart for Full Load Amps The information in this chart was derived from Table 50.1 of UL standard 508A. Amps - amount of the rate of flow of electricity, whereas Horsepower - … It has a max amp draw of 45 amps at 24 volts. The voltages listed are rated motor voltages. How to convert Hp to Amp AC 3 phases in only 3 step: Step 1: Multiply Hp (Horsepower) by 746. Solution: Current = [1 * 746] / [120 * 0.88 * 0.9] = 7.84 Amps. This online Horsepower to Amps Unit calculator allows you to convert electric motor Hp to Amps value in order to identify the value of electrical intensity based on the known Hp, efficiency, voltage. (100Hpx746 = 74600). Motor Current Rating Chart Series CA4, CA7, CA6 & CA5 The information in this chart was derived from Table 430-148 & 430-150 of the NEC and Table 50.1 of UL standard 508A. Single phase Amps = [HP * 746] / [E * %age Efficiency * PF] Example: Determine the amps in single phase 1 HP, 120-volt motor having an efficiency rating of 88% operating at a power factor 0.9. Horsepower (hp) = current draw (amps) x voltage/764. This online Horsepower to Amps Unit calculator allows you to convert electric motor Hp to Amps value in order to identify the value of electrical intensity based on the known Hp, efficiency, voltage. Horsepower (HP) is a measure of electric power equal to 746 watts (W). A = HP * 746 / (V* n * PF) Where A is the amps; HP is the horsepower Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts Continue reading to see how this formula was derived. Let’s take the 74 lbs of thrust trolling motor from Minn Kota as an example. Then you should make a guess as to the efficiency of the motor and there are always other power factors to affect the conversion rate. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F). The currents listed shall be permitted for system voltage ranges of 110-120, 220-240, 380-415, 440-480 and 550-600 volts. The voltages listed are rated motor voltages. Typical Full-Load Motor Current Chart for Three Phase Alternating-Current Motors: The … The Line Current I (A) = 746 x P (HP) / (√3 x pf x V (V)) in Amps. Amperes (amps) and horsepower (HP) are the electric motor's rating methods. Convert 10 hp to watts: P (W) = 746 ⋅ 10hp = 7460 W . Ampere is an SI unit of measurement of electric current. Converting horsepower to amps can be done in a few simple steps, or using this simple formula. Metric horsepower to watts. I … The currents listed shall be permitted for system voltage ranges of 110-120, 220-240, 380-415, 440-480 and 550-600 volts.
