método para estimar o momento de inércia de uma unidade rotativa de uma máquina de lavar ou de lavar e secar, e, máquina de lavar ou de lavar e secar

A method for estimating the moment of inertia (Je) of a rotating unit (7) of a washing or washing-and-drying machine (1) comprising the steps of: establishing one or more linear parameters (Ki(Éi)); rotating the drum (4) of the rotating unit (7) in such a way as to reach a set of speeds (Éi) of a pre-set value; once each speed (Éi) of a pre-set value is reached, detecting the value of the torque (Ti) provided to the rotating unit (7); and finally estimating the moment of inertia (Je) of the rotating unit (7) through a linear combination of the torques (Ti) detected and by means of the linear parameters (Ki).
