Can't find/understand constants in the MATLAB and Simulink Racing Lounge model

I have encountered various constants in the model list of constants that I am not capable of understanding/locating in the MATLAB and Simulink Racing Lounge model. These are the following: w_ref, w_max (which has a value lower than w_ref), Ftr_max, Ptr_max.
I would be truly grateful if you could explain what they mean and where they can be found in the model (what submodules). Moreover, is there a way of finding where a a constant is being used in a model from the list of constants in the Simulink workstation?
Lastly, why does the variable 'Spinloss' have a constant value of 6Nm? It seems intuitive that the losses on the rotating objects are dependent on the speed at which they are rotating and air resistance.
Many thanks.

Hi Diego,
I am not sure what exact model you are referring to. Could you please send the link or upload the model that you working on?
I am now guessing what you are experiencing ... . In the models of the racing lounge we are frequently using the model workspace. Find here a link explaining how you can access it: https://www.mathworks.com/help/simulink/ug/specify-source-for-data-in-model-workspace.html .
We are open to your follow-up questions?
Please mark this question as answered if the reply helped you.
Best regards, Christoph
