I find the unit of damping coefficient referenced from http://gazebosim.org/tutorials/?tut=r... and viscous friction coefficient in the motor which is usually expressed as Bm is (N*m)/(rad/s), so are they the same physical quantity? I want to simulate a servo motor, what value should the damping coefficient be?

If the damping coefficient = c and angular velocity = w, the damping force is c*w?

And, damping and viscous friction coefficient refer to the same thing. But as I know, we cannot set viscous friction coefficient, with damping instead.
