How to simulate DC motor rotation speed by MDO

[SK_13639906]

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

Refer to this thread for some insight into possible workarounds for motor models within MDO.

Thank you. I successfully ran MDO as I wanted to do by defining 

Motor Torque as a function of Measured Rotation Speed!
