A 4-pole, wave-connected, separately-excited D.C. motor has 43 slots on armature and each slot has 8 conductors. The motor has an armature resistance of 0.3 12 and the magnetic flux per pole is 0.015 Wb. If the motor draws an armature current of 8 A from a 120 V D.C. supply, evaluate (a) the back emf of the motor, (2 marks) (b) the motor speed in rev/min, and (4 marks) (c) the torque developed by the motor.
