SIMPLE AND ACCURATE MODELING OF A SIX-PHASE AXIAL FLUX PMSM FOR FAULT TOLERANT CONTROL

Modeling of multi-phase PMSM has been widely studied in the literature. Nevertheless, the methods applied for this achievement are complex due to the strong need to do an analysis of the magnetic field distribution inside the machine. In addition, mathematical transformations and calculations are required to implement such models. In the proposed study, a new modeling method is proposed based on a very simple theoretical computation approach with high accuracy. Its importance is that the model created will be used to do a fault tolerant control for the machine under study. The methodology is explained and presented first, the model is then simulated using the Matlab/Simulink software and finally validated by experimental tests using various topologies and hazards of electrical networks connected to the machine phases.
