Hi
I'm trying to interface the DC motor block (Simscape Electrical) to a revolute joint (Simscape Multibody). The aim is to develop a simulation model for a Pendubot.
Following several examples I think (I hope) I've made the connection properly, including the Rev-Rot interface to feedback the joint velocity into the DC motor but I have a doubt. If I want to change the friction, where is the right place to do it?. I've noticed that I can change the damping coefficient in the revolute joint (which is what I usually do) but it can be changed in the mechanical parameters of the DC block. (Rotor inertia).
Find attached a zip file with the simulink model and the stp files. Don't mind the commented blocks, just trying to model the motor non-linearity.
Thanks for your help.
Best regards

Hi Vicente
It shall work in both cases, but it is more natural to do it on the Simscape side (DC actuator). This makes sense if u wanted to add friction later on.
Good luck Juan

hello friend, if I want to add a coefficient of friction for the DC motor, how can I add it. I hope you can reply
