EKSPERIMENTALNO PREVERJANJE NUMERIČNO DOLOČENIH PARAMETROV ZA NELINEARNI DVOOSNI MODEL SINHRONSKEGA MOTORJA Z NOTRANJIMI TRAJNIMI MAGNETI
Povzetek
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.
