Inductances of a multiple coupled circuit machine model are calculated from its magnetic equivalent circuit. The modeled considers an electric machine with semi-closed slots.
A geometric approach of the well known winding-function approach for the calculation of electric machine inductances is presented in this paper. An elementary induction machine is used in order to validate the proposal.
A new strategy for broken rotor bars and load oscillation diagnosis on induction motors is presented. From the instantaneous active and reactive power theory, two current Park's vectors are obtained, the active and reactive Park's vectors. The analysis of the frequency spectrum of the modulus of these vectors allows both detecting broken bars and load oscillations, and the correct diagnosis of such...
