Multidisciplinary design analysis for PM motors with soft magnetic composite cores

This paper presents a multidisciplinary design analysis method for permanent magnet (PM) motors with soft magnetic composite (SMC) cores. Firstly, a multidisciplinary design analysis process is investigated to evaluate the performance of these motors, which includes electromagnetic analysis (based on new core loss model), thermal analysis, and mechanical modal analysis. Then a lumped 3-D thermal network model is developed for the thermal analysis in the design process. Finally, to demonstrate the effectiveness, a PM transverse flux machine (TFM) with SMC core is investigated. The numerical solutions including electromagnetic analysis and thermal analysis are validated by comparing with previous experimental results. Then Finite element model is employed to verify the obtained solutions in terms of thermal analysis and modal analysis for the optimal design scheme.
