Abstract: A method is provided for optimizing a parameter used in a frequency converter connected to an electrical rotating machine. The method includes identifying a parameter of the machine using electrical quantities, the identified parameter being used in the frequency converter and being identified in a first operating point, providing an electro-mechanical model of the rotating electrical machine to the frequency converter, and calculating when a processor capacity of the frequency converter is available, (i) a state of the rotating electrical machine in the first operating point using a finite element method with the electro-mechanical model of the rotating electrical machine, (ii) a state of the rotating electrical machine in a selected operating point using the finite element method with the electro-mechanical model, correcting the calculated state of the rotating electrical machine, and calculating, from the corrected state, parameter(s) of the electrical machine to be used in the frequency converter.
