Modeling a DC motor

  1. Mar 21, 2017 #1
    Hello, I want to model a DC motor which I bought from a company. I only have the following information:

    torque constant [M.N.M./Amp],
    EMF constant [MV/RAD/SEC],
    Dynamic Resistance [OHMS] and
    Motor Regulation [RPM./M.N.M.].

    The company does not provide the moment of inertia nor elect/mech time constant. As far as I know, I need all these three pieces of information in order to model the motor. Am I right? Is there a way to do it without the missing information?

    You should be able to measure the MMOI if you are willing to make some measurements.

    Hi Dr.D, which method do you recommend?
