Hello, I want to find the differential equation from the given simulink model:

I am not sure if i can get a differential equation from that picture

Hi,
The anwer is simple. 1/s means or its reverse means derivative. SO, the diff equations would be u_M(t) = dd(phi), d(phi)*k_M/J - phi*d/J =0.

Not quite exactly. The SImulink model originated from two ODEs which are:
u_M(t) = dd(phi)
d(phi)*k_M/J - phi*d/J =0
