20.500.12556/DKUM-86447 Development of mathematical models in explicit form for design and analysis of axial flux permanent magnet synchronous machines This article proposes a methodology for the design of double-sided coreless axial flux permanent magnet synchronous machines, which is based on a developed model for calculating the axial component of the magnetic flux density in the middle of the distance between opposite permanent magnets, which also represents the middle of the stator. Values for different geometric parameters represent the input data for the mathematical model in explicit form. The input data are calculated by using a simplified finite element method (FEM), which means that calculations of simplified 3D models are performed. The simplified model consists of two rotor disks with surfacemounted permanent magnets and air between them, instead of stator windings. Such a simplification is possible due to similar values of permeability of the air and copper. For each simplified model of the machine the axial component of the magnetic flux density is analyzed along a line passing through the center of opposite permanent magnets and both rotor disks. Values at the middle of the distance between the opposite permanent magnets are the lowest and are therefore selected for the input data at different stator, rotor disks and permanent magnets (PM) thicknesses. Such input data enable the model to consider the nonlinearity of materials. axial flux analysis coreless development design explicit form finite element method mathematical models permanent magnet synchronous tok analiza razvoj načrt eksplicitna oblika metoda končnih elementov matematični modeli trajni magnet sinhronost true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2023-12-01 13:53:21 2023-12-01 14:10:11 2025-02-07 13:56:29 0000-00-00 00:00:00 2020 0 0 Str. 1-17 št. 21, št. članka 7695 Letn. 10 okt. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-10-05 2020-10-21 2020-10-30 620.1/.2 35220227 10.3390/app10217695 2076-3417 Development_of_mathematical_models_Pranjic_2020.pdf Development_of_mathematical_models_Pranjic_2020.pdf 1 48060596FC2F70302219B9FD058A8ECB 862e6225ec1b44f14959487a5e7c8bc4c21e411b53efd6211ce916b23a561c8f cb0ad5b1-904a-11ee-bc08-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174503 https://doi.org/10.3390/app10217695 0 d850e0cc-904a-11ee-bc08-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174504 Fakulteta za energetiko 0 0 0
