ConclusionData for B-H curve of the proposed material

were acquired and analyzedB-H characteristic was implemented into

FEMM software and some parameters were verified

Next stepsOptimization of PMSM based on FEMM model Verification of FEMM modelConsidering the possibility of using other

materials and design
