A four-pole dc generator has magnetic flux of 0.06 Wb/pole, a rotational speed of 1800 rpm, full load current of 40 A, and is simplex lap wound. The generator efficiency is 91%. Pole face coverage is 78%. Calculate:
A. The number of conductors needed for Vout= 250 V at no load. (recall φ= BA)
B. The maximum armature current capacity of the generator.
C. The armature resistance (RA) if the load voltage is 240V at maximum armature current capacity.
