Horsepower is used to measure the rate of work, but amperage is a unit used to measure electric current. One unit of horsepower is equal to 745.7 watts. The watt is the product of the amperage and the voltage. If the voltage associated with the amps is known, the equation to determine the number of amps in one horsepower is 745.7 ÷ voltage = amps.
When the amp rating shown in Column 5 is not sufficient to start a motor, a larger amp rating is often available by utilizing 430.52(C)(1) Exception No. 2. The amp ratings in Column 6 are the larger of the amp rating allowed by 430.52(C)(1) Exception No. 1, or 430.52(C)(1) Exception No. 2. These amp ratings will often be

Motors are electrical devices that convert electrical energy into mechanical energy. They operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
when motor amps are not available. Heaters shown on the following pages provide a maximum trip rating of 125% of minimum motor amperes for 40˚C motors (service factor 1.15). For other motors (service factor 1.0), select the next lower listed heater catalog number within the designated table which provides a maximum trip rating of

The relationship HP x 746 / Vac x % efficiency will give approx. full load motor current for a 3 phase motor. For single phase motors, NEC table 430-148 gives 230 Vac full load current of 8 amps for a 1 HP motor. Note, that a 1 HP motor not fully loaded (good practice) will show current draw of less than 8 amps.
Answer (1 of 7): After seeing all the answers, I am really disappointed. Let me give you a very brief idea regarding this question. 1st of all you have to check whether it is a 3 phase or a single phase motor. you can check it on its name plate. Now, Relation between kW and current rating of a...

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. Horsepower = I (A) × V (V) × η × PF 746. Thus, horsepower is equal to the current in amps times the voltage in volts times the efficiency times the power factor, divided by 746.

Answer: Lakshya Saxena's answer to this question is wrong in every possible way. If it is still there, please report it. One mechanical HP is defined as about 757.7 watts. So if the motor is putting out the full rated 1HP at efficiency, the current usage would be Current = Power / Voltage ...
How to convert Hp to Amp AC 3 phases in only 3 step: Step 1: Multiply Hp (Horsepower) by 746. Example, if you have 100 hp multiply by 746 and you get 74600. (100Hpx746 = 74600). Step 2: Multiply the AC voltage by the motor efficiency, the power factor and the square root of 3.

An electric chain hoist uses a motor for the lifting operation. The spec sheet for the hoist will tell you the horsepower value for that hoist. If you are mounting the hoist to a motorized trolley, you will need to add the two horsepower values together (hoist and trolley) and then use the chart to determine the total amp draw.

First we must convert from hp to kW using this formula : 1 Hp = 0.746 kW. After that use the formula kW to ampere : For 3 phase power supply ; kW = I x V x 1.732 x pf. For 1 phase power supply ; kW = I x V x pf. Example :-. 1 unit induction motor power rated 25 hp,200 VAC,3 phase,90 % power factor,calculated the full load ampere. Calculation :-.
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. Also 5 HP three-phase motor takes 6.4 Amps. 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.
46.3. 32.4. 23.2. 1 hp = 745.7 W. Note that an electric motor is an inductive load. With low power factor it pulls lot of amps producing little hp output. Sponsored Links. Electrical - Electrical units, amps and electrical wiring, wire gauge and AWG, electrical formulas and motors. Sponsored Links.
