Questions about DC motor M/C

  1. Apr 11, 2010 #1
    1. The problem statement, all variables and given/known data
    Good evening again, my second question :

    3. The attempt at a solution
    I just have a question in part (c) ,,
    I know that E(a)=K(a)*Flux*w(omega)
    I did the following : (Eb85A/Eb100A) = (n85A/n100A) is it right ??
    I canceled K(a)85A with K(a)100A & the flux too (but isn't the flux different in Eb85A & Eb100A ?)

    Thanks in advance :smile:
