3 phase generator output voltage formula

  1. May 22, 2012 #1

    According to Faraday, a single phase generator ideal output voltage is:

    V = N*A*2PI*RPM/60*B

    Then should a three phase be:

    V = N*A*2PI*RPM/60* B * SQRT(3) ?

    I'm trying to build a spreadsheet to get ballpark numbers for simple variable speed generator design, but having difficulty empirically verifying against an existing generator. I may be calculating my Area or Flux Density incorrectly, but thought I'd get a sanity check on the basic formula first.

    I assume I should be measuring open load peak-to-peak voltage? It's wye connected measuring line to tline.

    Thanks in advance.
