A shunt motor with an armature resistance of 0.15ohms is running 1200rpm for a load which requires an armature current of 50A from 230V source. At no load, the armature current of 5A. If the effect of the armature reaction has reduced the air gap flux 2% from no load to full load, what is the no load speed?
