SOLVE STEP BY STEP IN DIGITAL FORMAT A 240v, 12hp, 1400rpm cumulative compound motor has an armature resistance of 0.40 Ω, a combined offset winding and interpolation resistance of 0.32 Ω, a brush voltage drop of 4v. The series field resistance is 0.18 Ω and its shunt field resistance is 200 Ω. When the motor is connected in shunt, the rated line current at full load is 62 A and at no load is 5.5 A. The speed no load is 1850 rpm. Calculate: a) The speed at full load. b) The internal power that is developed in w and hp.
