【Summary】:
Switched reluctance motors muaj ob yam tseem ceeb: 1) Switching, switched reluctance motors yuav tsum tau ua hauj lwm nyob rau hauv tas mus li hloov hom; 2) Switched reluctance motors yog doubly salient variable reluctance motors. Nws lub hauv paus ntsiab lus yog tias thaum lub rotor tig, qhov tsis txaus siab ntawm cov hlau nplaum yuav tsum hloov ntau li ntau tau. Nyob rau hauv qhov tseeb, cov hlau nplaum ruaj khov nyob rau hauv lub rotor ntawm lub zoo tib yam mus tas li hlau nplaum lub cev muaj zog kuj yuav ua rau qhov kev hloov ntawm lub reluctance ntawm lub salient ncej ntawm lub rotor, yog li lub torque ntawm lub mus tas li hlau nplaum lub cev muaj zog kuj muaj xws li lub reluctance torque.
Switched tsis kam motorsmuaj ob tug yam ntxwv tseem ceeb: 1) Hloov, hloov tsis kam lub cev muaj zog yuav tsum tau ua hauj lwm nyob rau hauv tas mus li hloov hom; 2) Switched reluctance motors yog doubly salient variable reluctance motors.Nws lub hauv paus ntsiab lus yog tias thaum lub rotor tig, qhov tsis txaus siab ntawm cov hlau nplaum yuav tsum hloov ntau li ntau tau.Nyob rau hauv qhov tseeb, cov hlau nplaum ruaj khov nyob rau hauv lub rotor ntawm lub zoo tib yam mus tas li hlau nplaum lub cev muaj zog kuj yuav ua rau qhov kev hloov ntawm lub reluctance ntawm lub salient ncej ntawm lub rotor, yog li lub torque ntawm lub mus tas li hlau nplaum lub cev muaj zog kuj muaj xws li lub reluctance torque.
1. Ontology qauv
Cov ncej tseem ceeb ntawm stator thiab rotor ntawm lub tshuab hloov pauv tsis kam yog ua los ntawm cov hlau silicon hlau laminations.Cov txheej txheem machining no txo qis eddy tam sim no thiab hysteresis poob hauv lub cev muaj zog.Tsis muaj qhov windings los yog cov hlau nplaum ruaj khov ntawm cov ncej rotor, los yog cov commutators, cov hlua khi, thiab lwm yam.Lub stator ncej yog qhov txhab nrog cov ntsiab lus windings, thiab ob lub radially opposite windings yog txuas nrog rau hauv series los tsim ib theem, thiab tag nrho cov qauv ntawm lub cev muaj zog yog yooj yim.
Switched reluctance motors tuaj yeem tsim nrog ntau theem raws li qhov xav tau.Raws li cov theem, nws tau muab faib ua ib theem, ob-theem, peb-theem, plaub-theem thiab ntau-theem reluctance motors.Txawm li cas los xij, switched reluctance motors hauv qab peb-theem feem ntau tsis muaj peev xwm pib tus kheej.Qhov ntau theem ntawm lub cev muaj zog, qhov me dua lub kaum sab xis, uas yuav pab txo qis torque ripple.Txawm li cas los xij, qhov ntau ntawm cov theem, cov khoom siv hloov pauv ntau dua, cov qauv siv ntau dua, thiab cov nqi sib xws yuav nce ntxiv.Peb-theem thiab plaub-theem motors feem ntau siv niaj hnub no.Tus naj npawb ntawm tus ncej ntawm stator thiab rotor kuj txawv. Piv txwv li, peb-theem hloov tsis kam lub cev muaj zog muaj 6/4 qauv thiab 12/8 qauv, thiab feem ntau ntawm plaub-theem hloov tsis kam motors muaj 8/6 qauv.
2. Lub hauv paus ntsiab lus ua haujlwm
Ib tug switched reluctance motoryog lub cev muaj zog uas siv qhov tsis sib xws ntawm lub rotor los tsim lub zog, tseem hu ua reactive synchronous lub cev muaj zog.Nws cov qauv thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm yog txawv ntawm cov tsoos AC motors thiab DC motors.Nws tsis cia siab rau kev sib cuam tshuam ntawm magnetic teb los ntawm stator thiab rotor winding tam sim no los tsim torque.
3. Cov yam ntxwv ntawm Switched Reluctance Motor
Nyob rau hauv 20 xyoo dhau los, switched reluctant motors tau them ntau thiab ntau xim los ntawm cov neeg.Nws yog qhov tseeb vim tias nws muaj cov yam ntxwv pom tseeb tias nws qhov zoo thiab qhov tsis zoo yog qhov tseem ceeb sib npaug.Cia peb tham txog qhov zoo ua ntej.
1. Lub tshuab hluav taws xob hloov tsis kam muaj kev ua haujlwm siab thiab kev txuag hluav taws xob zoo: nyob rau hauv ntau hom kev tswj ceev thiab lub zog, qhov hloov tsis kam lub cev muaj zog feem ntau ua haujlwm zoo dua li lub asynchronous lub cev muaj zog sib txawv ntawm qhov kev tswj hwm ceev, thiab qhov ua tau zoo tuaj yeem siab dua. tshaj 10 ntawm qhov ceev los yog lub teeb load. %; Piv nrog rau cov tshuab xws li iav motor deceleration, Secondary pulley deceleration.
2. Lub cev muaj zog tuaj yeem pib thiab nres tsis tu ncua, thiab kev sib hloov rau pem hauv ntej thiab thim rov qab yog nquag: plaub-quadrant kev khiav hauj lwm tswj ntawm lubswitched tsis kam lub cev muaj zogyog hloov tau. Thaum muaj chav nres tsheb thiab lub zog nres ua tau raws li qhov yuav tsum tau ua, qhov kev hloov pauv ntawm kev pib-nres thiab rau pem hauv ntej thiab thim rov qab tuaj yeem ncav cuag ntau tshaj li ntau pua zaus hauv ib teev.
3. Lub cev muaj zog tseem tuaj yeem ua haujlwm nyob rau hauv cov theem poob lossis overload: Thaum lub hwj chim tawm ntawm theem lossis ib theem ntawm lub cev muaj zog lossis tus tswj tsis ua haujlwm, qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob hloov pauv tuaj yeem txo qis, tab sis nws tseem tuaj yeem ua tau. khiav.Thaum lub kaw lus tshaj qhov ntsuas load los ntawm ntau tshaj 120%, qhov ceev tsuas yog poob, thiab lub cev muaj zog thiab tswj yuav tsis raug hlawv.
