If you have no Angular Drag on the RigidBody2D you need just do AddTorque() once (but with a smaller value than you are doing now) to ac$$anonymous$$eve constant rotation speed. If Angular Drag is >0 you need to keep doing AddTorque() in FixedUpdate() but with a very small constant value, and Drag and Torque will eventually reach a constant top rotation speed. If you instantly want to rotate at constant speed, you set rb.rotation each FixedUpdate() to the same small value regardless of Angular Drag.

Your question is too imprecise to give any more specific answer.

Well I need rotation that can rotate the log at some constant speed. I want to keep things simple. You answer perfect man, but it is ok to use Rigidbody2D.angularVelocity? It just curiosity that's why I asked . Also I read in documentation that angularVelocity case some behavior problems...
