The Determination of the Inertia Moments and the Dependencies of the Friction Torque to the Revolutions

In this paper there are presented a few ways of determining the inertia moments (working at two revolutions, determining using the launch method, determining using the measurement of electric energy at start) and of the dependency of the friction torque by revolution. For estimating the value of the inertia moment, we considered just the industrial case in which J is constant duringregulation at all the operating regimes.
