I-switched reluctance motor iyinjini elawulwa isivinini eyakhiwe ngemuva kwe-DC motor kanye ne-brushless DC motor, futhi isetshenziswa kakhulu ezintweni zasendlini, ezondiza, i-aerospace, electronics, imishini kanye nezimoto zikagesi. I-switched reluctance motor inesakhiwo esilula; injini inesakhiwo esilula nezindleko eziphansi, futhi ingasetshenziselwa ukusebenza ngesivinini esikhulu. Isakhiwo se-squirrel-cage motor induction silula kune-squirrel-cage induction motor. I-rotor yayo inamandla amakhulu emishini futhi ingasetshenziselwa ukusebenza ngesivinini esikhulu (njengamashumi ezinkulungwane zama-revolutions ngomzuzu).
Ushintshe injini yokungabazaiyinjini elawulwa isivinini eyakhiwe ngemva kwe-DC motor kanye ne-brushless DC motor, futhi isetshenziswa kakhulu ezintweni zasendlini, ezondiza, i-aerospace, electronics, imishini kanye nezimoto zikagesi.
Izici eziyinhloko zesistimu yokulawula isivinini se-switch reluctance motor:
Isakhiwo esilula; injini inesakhiwo esilula nezindleko eziphansi, futhi ingasetshenziselwa ukusebenza ngesivinini esikhulu. Isakhiwo se-squirrel-cage motor induction silula kune-squirrel-cage induction motor. I-rotor yayo inamandla amakhulu emishini futhi ingasetshenziselwa ukusebenza ngesivinini esikhulu (njengamashumi ezinkulungwane zama-revolutions ngomzuzu). Ngokuqondene ne-stator, inama-windings ambalwa kuphela agxiliwe, ngakho-ke kulula ukwenza futhi isakhiwo sokufakelwa silula.
Ukwethenjelwa kwesifunda se-motor eshintshashintshayo yokungafuni; isifunda samandla silula futhi sithembekile. Njengoba isiqondiso se-torque ye-motor singahlangene nesiqondiso samanje esimazombezombe, okungukuthi, isigaba esisodwa kuphela esidingekayo samanje, isifunda samandla singakwazi ukubona ukushintshwa kwamandla okukodwa ngesigaba ngasinye. Uma kuqhathaniswa nama-asynchronous motor windings adinga i-bidirectional current, i-PWM inverter power circuit ebanikezayo idinga amadivaysi amabili kagesi ngesigaba ngasinye. Ngakho-ke, isistimu yokulawula isivinini semoto eshintshashintshayo idinga izingxenye zamandla ezimbalwa kanye nesakhiwo sesekethe esilula kunesekhethi yokunikeza amandla i-pulse wide modulation inverter. Ngaphezu kwalokho, kumjikelezo wamandla we-inverter ye-PWM, amashubhu okushintsha amandla amabili engalweni ngayinye yebhuloho anqamula ngokuqondile ohlangothini lokuphakelwa kukagesi we-DC, okungenzeka kubangele ukujikeleza okufushane okuqondile kushise idivayisi yamandla. Kodwa-ke, idivayisi ngayinye yokushintsha amandla kusistimu yokulawula isivinini semoto eshintshayo ixhunywe ngokuqondile ochungechungeni lwama-motor winding, olugwema ngokuyisisekelo ukwenzeka kokujikeleza okufushane okuqondile. Ngakho-ke, umjikelezo wokuvikela wesekethe yokuphakelwa kwamandla ohlelweni lokulawula isivinini semoto yokunqikaza eshintshiwe ungenziwa lula, izindleko ziyancipha, futhi ukwethembeka kuphezulu.
