How to simulate DC motor rotation speed by MDO

Hello

I am trying to simulate the motion speed of a mechanism operated by DC motor.

DC Motor Rotation Speed varies with the input torque as attached graph.

But it seems impossible to define Motor Rotation Speed by using measured input

torque in MDO.

(There is only servo motor, whose speed does not depends on input torque)

In this case, are there any method to simulate with the DC motor?

I can calculate this motion in excel or mathcad, based on Torque value at each position angle from creo simulation with servo motor.

But It would be great if this could be done just in Creo, or with a simpler workflow
