Modeling of a PMSynRel stator with concentrated windings using FEM and non-linear reluctance networks

Permanent magnets synchronous reluctance (PMSynRel) motors are attractive due to theirhigh torque density and because a lower quantity of permanent magnets is necessary incomparison with other permanent magnet machines. This thesis deals with the analysis ofPMSynRel machines using a finite element method (FEM) and reluctance networks.First, a PMSynRel machine model is built in order to carry out simulations usinga finite element method package. The effect of different design parameters such as thecombination of the number of poles and slots, the number of flux barriers or the numberof magnets can be studied since the implementation provides the possibility to changethose variables.Next, a reluctance networks model, aimed to enable lower computation times thancorresponding finite element models, is implemented for analysing the flux density distributionsalong the air gap of the machine disregarding the magnetic influence of therotor. Finally, the results are compared with FEM simulations. It is concluded that theagreement reached is satisfactory in most of the cases analysed.
