Problem 3 A 250 V d.c. shunt motor runs at 1000 rpm. and takes an armature current of 25 amp. Its amature resistance is 0.40 ohm. Calculate the speed with increased load with the armature current of 50 amp. Assume that the increased load results into flux-weakening by 3%, with respect to the fux in previous loading condition

please help me this is all about dc machine 

Problem 3 A 250 V d.c. shunt motor runs at 1000 rp.m. and takes an armature curent of 25 amp. Its amature resistance is 0.40 ohm. Calculate the speed with increased load with the armature curent of 50 amp. Assume that the increased load results into flux-weakening by 3%, with respect to the flux in previous loading condition.
