Coupling Boundary Element and Permeances Network Methods for Modeling Permanent Magnet Motors in automotive applications

摘要

The aim of this work is to propose the hybridisation of Boundary Element Method (BEM) with Permeances Network Method (PNM) for computing linkage fields in Outer Rotor Permanents Magnets synchronous machines (OR-PMSM). One of the employed techniques is the evaluation of air-gap permeances starting for Finite Element Method (FEM) software. This approach consumes a lot of times and this is limited for design processes. In this study, a new strategy using the BEM in the air-gap permeances evaluation is presented. So the high ratio fast of running/computing errors of the proposed methodology has been checked out.
