I was responding to the "fall precipitously" portion of your comment:

The differential equation for the current through the motor during the off portion (when the motor leads are both shorted to ground) is

R*i + L*(di/dt) + Vemf = 0

That would be of interest. To my knowledge, no one has ever posted the results of such a test here, nor has anyone ever posted a link to an authoritative CIM motor spec which includes inductance.
