• "Help me! Urgent!"

Here is the question:
A 500-hp, 600-volt DC motor operates at 495rpm at full load. If the flux per pole is 9.1webers and the armatute resistance is 15million-ohm and K-1.3 exp(-7). Calculate the counter induced EMF.

Hopeful someone will give some shot to answer. Thank you in advanced

 

I doubt anyone will give you an answer. If you show your work to the point you get stuck, it is highly likely that someone will guide you to the solution.
