(a) What is the difference between a DC Generator and a DC motor? (6)

(b) A 4-pole, 32 conductor, lap-wound DC shunt generator with terminal voltage of 200 V delivering 12 A to the load has Ra = 2 and the circuit resistance of 200 Ω. It is driven at 1000 RPM. Calculate the (10)

(i) Flux per pole of the machine.

(ii) If the machine has to be run as motor with the same terminal voltage and drawing 5 A from mains, maintaining the same magnetic field, find the speed of the machine.
