HOW TO DO IT
Analyzing acquired data
Hysteresis loop of the toroidal shape core;
applied current 3 A, applied frequency 250 Hz
HOW TO DO IT
Application of analyzed data
FOR WHAT USE IT
Implementation into FEMM
software
Application of analyzed data
Results of the FEMM analysis
FOR WHAT USE IT
Verification of FEMM analysis
PMSM prototype
FOR WHAT USE IT
Torque of PMSM in FEMM = 0.01... [N.m]
Activating PMSM
Torque of real PMSM= 0.01... [N.m]

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
