Homework Help: Speed of a generator?

  1. Jun 30, 2014 #1
    1. The question is "what speed will the generator need to be driven to give an output of 240V D.C?" the generator is constructed using one pole pair having a sq surface of 6cm x 6cm and produces a flux of 18mWb. It has 4 commutator segments.

    2. Possibly F = (P * N) / 120? im not sure

    3. F = (P * N) / 120 = (2*3000(dont know the number of turns this was a guess)?)/120 = 50

    How many loops does it have? 1 or 2?
