A 30KW motor running at 1450 rpm draws 56A, how would you determine if this is correct or not?..

Answer / divakaran a

P=1.732xVxIxP.F
30KW=1.732x415xIx0.8
I=30000/(1.732x415x0.8)
I=52.17 AMPS

sO the current drawing from the motor is 52 amps (Theoriticaly)

in practical the motor may draws more current as based on the load.

Answer / vipul kumar rai

P=1.732xVoltage x I(current )xPower Factor
30KW=1.732x415xIx0.8
I=30000/(1.732x415x0.8)
I=52.17 AMPS

as per thory 52.17A current draw.
so 56A is approx correct.
