Horsepower to Amps Unit Calculator
English

Horsepower is the unit of measurement of work done, that is power. It is expressed in foot-pound-second. It is a unit used to measure the output power in machineries. Ampere is an SI unit of measurement of electric current. One Amps is equal to One coulomb per second. 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.

Formula:

1 Ph.Amps = ((( (746 x hp) / V ) / E.F ) / P.F ) 1.FLA = ( (1 Ph.Ampere) x 1.25 ) 3 Ph.Amps = (((( (746 x hp) / 1.732 ) / V ) / E.F ) / P.F ) 3.FLA = ( (3 Ph.Ampere) x 1.25 ) Where, V - Volts, E.F - Efficiency, P.F - Power factor, FLA - Full Load Amps.

Example

Horse power produced by an electrical motor is 7 with voltage of 40 V at a rate of efficiency 78% with a power factor of 40%. What is its equivalent Ampere current?

1 Ph.Ampere = ((( (746 x 7) / 40) / 0.78) / 0.40)
    = 418 A

1.FLA = ((418) x 1.25)
    = 523 A

3 Ph.Ampere = (((((746 x 7) / 1.732) / 40) / 0.78) / 0.40)
    = 242 A

3.FLA = ((242) x 1.25)
    = 303 A
