DC motor model in Simscape is not working

3 次查看(过去 30 天)
Hello!
I am trying to run a simple model of a DC model in Simscape but I am having some troubles to make it work. When I add a "ideal torque sensor" and a "ideal rotational sensor" the output shows that the rod is not moving. I cannot see what I am doing wrong... Can you help me?

Hi Alvaro,
From the model you have shared, it can be seen that you have connected the “Ideal torque sensor” block in parallel with your circuit. It should be connected in series.
You can consider the torque analogous to current and the torque sensor analogous to an ammeter. By connecting it in parallel, as you have done, you are effectively creating a short circuit, hence there is no rotation of the motor. Hope this helps.
