20.500.12556/DKUM-86324 Experimental verification of the numerically determined parameters for the non-linear two-axis model of a synchronous motor with interior permanent magnets Eksperimentalno preverjanje numerično določenih parametrov za nelinearni dvoosni model sinhronskega motorja z notranjimi trajnimi magneti Synchronous machines belong to the family of electrical machines characterised by a synchronous magnetic rotating field in the air gap of the machine, the speed of which depends on the frequency of the currents in the armature winding. The paper presents procedures and methods for the numerical determination and experimental verification of the parameters for a nonlinear two-axis model of a synchronous motor with permanent magnets in the rotor (IPMSM) and a concentrated stator winding. To calculate the distribution of electro-magnetic fields in the motor accurately, models with distributed parameters are used in motor design, for which the Finite Element Method (FEM) is usually employed. The improvement by using the model with concentrated parameters considerably simplifies the physical model, by describing it with a system of (non)linear differential equations, the so‐called partial differential equations, which is presented in this paper. Sinhronski stroji spadajo v družino električnih strojev, za katere je značilno sinhrono magnetno vrtljivo polje v zračni reži stroja, katerega hitrost je odvisna od frekvence tokov navitja armature. V prispevku so predstavljeni postopki in metode za numerično določanje in eksperimentalno preverjanje parametrov za nelinearni dvoosni model sinhronskega motorja s trajnimi magneti v rotorju (IPMSM) in koncentriranim statorskim navitjem. Pri načrtovanju motorjev se za natančnejši izračun porazdelitve elektromagnetnih polj v motorju uporabljajo modeli s porazdeljenimi parametri, za kar se običajno uporablja metoda končnih elementov (MKE). V prispevku je predstavljena izboljšava, ki z uporabo modela s koncentriranimi parametri v osnovi znatno poenostavi fizični model, tako da ga opiše s sistemom (ne)linearnih diferencialnih enačb, tako imenovanih delnih diferencialnih enačb. synchronous motor flux linkage interior permanent magnets non-linear sinhroni motor notranji trajni magneti nelinearnost true false true Fakulteta za energetiko Univerze v Mariboru Angleški jezik Slovenski jezik Znanstveno delo 2023-11-13 10:20:01 2023-11-13 10:32:08 2023-12-01 13:27:40 0000-00-00 00:00:00 2021 0 0 str. 11-19 št. 4 letn. 14 dec. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-12-01 621.311.243 99776003 1855-5748 Experimental_verification_of_the_numerically_determined_parameters_Hederic_2021.pdf Experimental_verification_of_the_numerically_determined_parameters_Hederic_2021.pdf 1 E150021FAB68B2FD5DC3F2282B3456D2 aa305a6ae033354e85c29619141204bc55f8e534040fbde781324364b17d4388 656bda6d-8207-11ee-b12e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174085 https://www.fe.um.si/e-jet/44-2021-1/3319-december-2021.html 0 d47be08f-8205-11ee-b12e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174084 Fakulteta za energetiko Journal of energy technology 0 0 0
