Induced Voltage in a Generator

  1. Nov 20, 2016 #1
    1. The problem statement, all variables and given/known data
    I want to know the minus/plus sign of induced voltage of each rotor segment. Like in file no.3, equation 4-19, why (vxB)•l is not equal to eab instead?
    2. Relevant equations

    equation 1-45: eind = (vxB)•l
    equation 4-19: eba = (vxB)•l = vBl (case I: positive into page under the pole face ) = 0 (case II: beyond the pole edges)
    3. The attempt at a solution
    I was searching on this book, but found nothing.

    Here are the pictures that were unclear last time. I can zoom into them very close.

    Thank You

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    I'm sorry. I still don't have any new conclusions yet. But I keep looking for theories related to this question. As soon as I figure it out, I'll let everyone know.

    Thank you
