Answers were Sorted based on User's Feedback
Answer / chethan
V=415 ,cos=0.8
1HP = 746 Watts
p=1.732*V*cos*I
746=1.732*415*0.8*I
I=746/575.025
Ans.1.297

what is the load amp for 1 HP 3Phase Motor?
= HP/Root 3*V*I*Cos,
I=?
1 Hp=746 watt,
I=746/1.732*415*0.8,
I=746/575.024,
I=1.29amps,,,,,,,
1hp=1.29amps

Answer / karan
the thumb rule is,I= H.P*1.5
but current depend on Power factor,
Example power factor is 0.85
1 H.p=750kw=Root3*V*I*cosQ=1.73*415*I*0.85
so I=750/1.73*415*0.85=1.23 Amp
when pf is 0.80 then I=1.30
when pf is 0.95 then I=1.09
