Vibration analysis of permanent magnet synchronous motor using coupled finite element analysis and optimized meshless method

Abstract

FEA-meshless method and complete FEA coupled method are compared. It is worth noting that optimized method significantly improves accuracy, robustness and computational speed at the same time. In short, the proposed electromagnetic-structure coupling calculation method provides a novel alternative for the multi-physics coupling calculation of rotating machinery combining FEA and meshless simulation methods.Keywords Finite element analysis.
