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

Answer Posted / 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.

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
