In the flrst part of this work, we develop a model to compute linkage flelds in Outer Rotor Permanents Magnets synchronous machines (OR-PMSM), a structure which is often used in the automotive traction motors. To carry out such a design, we usually employ Finite Element analysis (FEA) software even if it is time consuming. Other designers prefer the Permeances Network Method (PNM) which is less accurate and needs o†ine FEM results to evaluate the unknown air-gap permeances. Comparatively, between FEM and BEM, the flrst method is more precise whereas the second is faster in computing times. We propose here a new technique using the hybridization of both methods in order to gain the advantages of the two techniques, i.e., a relatively accurate and fast methods, so the high ratio of fast running to computing errors has been achieved. The second part deals with the multi-objective design optimization of the studied motor. To do this, we choose the decrease of cogging torque and the increase of torque as objectives applied to multi-objective optimization (MO) process.
