There are other torques at play, resisting flywheel motion (like viscous friction for example).

Ks*Wf*G is an attempt to model those torques.

You can set Ks=0 if you like, but then the flywheel speed will converge to Wo/G, which we all know by experience is not the way the real world works.

If you like, you can replace Ks*Wf*G with a constant loss, or a quadratic loss, or any function of speed that you want.
