A 4-pole, lap wound DC long-compound motor consists of 200 turns. The motor has a shunt field resistance of 100 12, a series field resistance of 0.1.1, an armature resistance of 0.4.2, and the stray power loss is 50 W. The motor is supplied from a 400 V source. Flux per pole in the air-gap is 0.0314 Wb. Calculate at 1815 rpm: a) Full-load torque. b) No-load speed and speed regulation. c) Output power.
