I would need to look up the measured value from my old models, I do not recall off the top of my head what the measured inductance value was. I'll provide it as soon as I can.


As for the units for Ke, you are correct. The units must satisfy this equation:

emf [Volts] = Ke [Volts/(rads/sec)] * AngularVelocity [rads/sec]

Looks like I left off the parentheses in my original post. I will edit my post to add parentheses to make it clear. Thank you for catching the typo.

Regards,
Kevin
