A six-pole, lap-wound, 220 V, shunt-excited d.c. machine takes an armature current of 2.5 A when unloaded at 950 r/min. When loaded, it takes an armature current of 54 A from the supply and runs at 950 r/min. The resistance of the armature circuit is 0.18 Ω and there are 1044 armature conductors. For the loaded condition, calculate: i. the induced e.m.f. ii. the useful flux per pole. iii. the torque developed by the machine in Nm. b) Use the information provided in Part (a) above to determine: i. The constant loss, C (ANS: 548.875 W) ii. The output power when the machine is loaded. (ANS: 10,806.245 W) iii. The output torque when the machine is loaded. (ANS: 108.623 N) Hint: Draw the power flow diagram.
