I want to simulate voltage drop effects on cranking motor. I have motor specifications and its performance curves. But I dont know how to model this machine using DC machine model available in sim power systems, as it requires circuit parameters which I don't have. Help me with modelling this motor for given specifications. Details: 24 V, 6000rpm(no load speed),1200 rpm(full load speed), 100A (no load current), 760A(full load current).
