A 6 pole, 2 circuit, wave-connected armature has 250 conductors and runs at 1200 r.p.m. The electromotive force generated on open-circuit is 600V. Find the useful flux per pole. An 8-pole, lap-connected armature has 960 conductors, a flux of 40mwb per pole, and a speed of 400 rpm. Calculate the e.m.f. generated on open-circuit. If the armature in (b) were wave-connected for 2 circuit, at what speed must it be driven to generate 400V. A 4-pole generator has a flux of 40mwb per pole and a lab-connected armature with 740 conductors, Find the e.m.f. generated on open circuit at 1000 r.p.m.
