I am running into the following error not able to debug it. First I though, that I might have a unit mismatch but after rechecking, everything seems to be consisten so far. What is the cause for the error?
I am looking for the function phi(t). I have no clue, why the solve-block runs into a error. I think it might have to do something with the following equation, because when I remove J_Motor*2*Pi*n'(t), the solver is able to give me phi(t).
