20.500.12556/RUL-167351 Fast and accurate non-linear time-domain modeling of synchronous machines The paper presents a novel method for non-linear 2D magnetic analyses of synchronous electric machines, with the emphasis on permanent magnet and synchronous reluctance AC machines with distributed windings. The foundation of the methodology lies in the air gap magnetic flux being an integral quantity, connecting the two magnetic structures – stator and rotor. The implementation was done through the fixed magnetic permeance configuration. In the method, the rotor and stator sub-models of different complexity were developed, that iteratively exchange the results between each other via the frozen permeability method, until a sufficient accuracy is achieved. Each of the sub-models can have an arbitrary number of nodes for scalar magnetic potentials, in order to accurately describe the magnetic conditions. However, we showed in the paper that only a small number of nodes in both sub-models is sufficient to achieve the accuracy of the results, comparable with the 2D finite element method results. The small number of nodes reflects in the reduced computational efforts of the presented method, giving it a promising forecast for numerous analyses, e.g. for calculations of voltage forms, inductances, armature reaction effects, iron loss estimations, etc. and further, for various optimization procedures. electromagnetism electric machines frozen permeability magnetic analysis magnetic equivalent circuit permeance configuration synchronous machines permanent magnets elektromagnetika električni stroji zamrznjena permabilnost magnetna analiza magnetno nadomestno vezje permeančna konfiguracija sinhronski stroji trajni magneti true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-17 13:22:43 2025-02-17 13:22:48 2025-06-18 14:18:55 0000-00-00 00:00:00 2025 0 0 Str. 26289-26303 Vol. 13 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.313/.314 2169-3536 10.1109/ACCESS.2025.3539780 226213379 Fast_and_Accurate_Non-Linear_Time-Domain_Modeling_of_Synchronous_Machines.pdf Fast_and_Accurate_Non-Linear_Time-Domain_Modeling_of_Synchronous_Machines.pdf 1 E8F19947347E9C18CEED71E5ED29A7E3 9c10155856185ce4012187ef92d2c152a6f9d65008f68cbf0abcfdabb5e30f49 1dce21ba-ed29-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199718 https://ieeexplore.ieee.org/document/10877819 1 02e11d41-ed29-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199717 Fakulteta za elektrotehniko 0 0 0
