I come here again for your help.
I try to simulate a DC motor functionning on the basis of the model "ssc_dcmotor" from Simscape (see picture):
The outcomes seem to be consisten regarding what I expect (value and profile of speed/current).
Then, I made some changes (actually I copy/paste this model in a bigger one to link with a gear box and a lead screw). The modifications are: adding a Torque sensor, as well as change the mask of the DC motor to display the name of my ports (which should not influence the functionning...).
Now comes the drama: my speed is 0 and my current comes to his max. and stay at the maximal value for the rest of simulation time (blocked rotor behavior).
I just don't understand what did I do wrong... Somebody know this issue?
Enclosed is the concerned model
Thanks in advance
