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.
