A 10 - hp, 250-V shunt motor has an armature circuit resistance of 0.5 and a ?eld resistance of 200 . At no load, rated voltage, and 1200r/min, the armature current is 3 A. At full load and rated voltage, the line current is 40A, and the flux is 5% less than its no-load value because of armature reaction. Compute the full-load speed.
