what is the load amp for 1 HP 3 phase Motor ?..

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 3 phase Motor ?..

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
