Peb txhua tus paub tias lub tshuab hloov pauv tsis txaus siab muaj cov yam ntxwv ntawm kev txuag hluav taws xob, uas txawv ntawm lwm cov khoom zoo sib xws, uas tseem muaj feem xyuam nrog cov qauv ntawm cov khoom. Txhawm rau kom txhua tus neeg nkag siab ntau dua intuitively, tsab xov xwm no qhia txog cov ntaub ntawv ntsig txog cov qauv hauv kev nthuav dav.
Switched reluctance motors tsim torque los ntawm attracting ib tug magnetic salient ncej rotor mus rau stator magnetic teb. Txawm li cas los xij, tus naj npawb ntawm stator ncej yog qhov tsawg. Cov hlau nplaum ntawm lub rotor yog qhov yooj yim dua vim yog cov hniav profile es tsis yog qhov cuam tshuam sab hauv. Qhov sib txawv ntawm tus naj npawb ntawm cov ncej hauv stator thiab rotor ua rau cov nyhuv vernier, thiab rotor feem ntau rotates nyob rau hauv cov lus qhia sib txawv thiab ntawm qhov sib txawv ceev mus rau stator teb. Feem ntau yog siv DC excitation, xav tau lub zog inverter ua haujlwm. Switched reluctance motors kuj tseem ua txhaum loj heev. Yog tsis muaj hlau nplaum, tsis muaj kev tswj tsis tau torque, tam sim no, thiab tsis muaj kev tswj xyuas tiam ntawm kev kub ceev nyob rau hauv winding txhaum tej yam kev mob. Tsis tas li ntawd, vim hais tias cov theem yog hluav taws xob ywj pheej, lub cev muaj zog tuaj yeem ua haujlwm nrog cov zis tawm yog tias xav tau, tab sis thaum ib lossis ntau theem tsis ua haujlwm, lub cev muaj zog torque ripple nce. Qhov no tuaj yeem pab tau yog tias tus tsim qauv xav tau kev zam txim thiab rov ua dua. Cov qauv yooj yim ua rau nws ruaj khov thiab pheej yig rau kev tsim khoom. Tsis xav tau cov khoom kim heev, cov hlau rotors yog zoo meej rau kev kub ceev thiab hnyav ib puag ncig. Luv nrug stator coils txo qhov kev pheej hmoo ntawm luv circuits. Tsis tas li ntawd, qhov kawg lem tuaj yeem luv luv, yog li lub cev muaj zog yog compact thiab tsis tsim nyog stator poob.
Switched reluctance motors yog qhov zoo tagnrho rau ntau yam kev siv thiab tau siv ntau dua hauv kev tuav cov khoom hnyav vim lawv qhov tawg loj thiab cov torques ntau dhau, qhov teeb meem tseem ceeb ntawm cov khoom yog lub suab nrov thiab kev co. Cov no tuaj yeem tswj tau los ntawm kev ua tib zoo tsim kho tshuab, kev tswj hluav taws xob, thiab yuav ua li cas lub cav tsim los siv.
