Winding yog ib qho tseem ceeb heev nyob rau hauv cov txheej txheem ntawm lub cev muaj zog ntau lawm thiab ua. Txawm hais tias nws yog qhov tseeb ntawm lub cev muaj zog winding cov ntaub ntawv lossis kev ua raws li kev ua haujlwm ntawm kev rwb thaiv tsev ntawm lub cev muaj zog winding, nws yog ib qho tseem ceeb qhia uas yuav tsum muaj nuj nqis heev hauv kev tsim khoom.
Nyob rau hauv ib txwm muaj xwm txheej, lub cev muaj zog cov tuam txhab yuav xyuas cov naj npawb ntawm cov lem, ib txwm tsis kam, thiab hluav taws xob rwb thaiv tsev kev ua tau zoo ntawm cov windings thaum lub sij hawm winding txheej txheem thiab ua ntej dipping xim tom qab xaim; tom qab ntawd nws yog kev tshuaj ntsuam xyuas thiab hom kev xeem kom raug txiav txim siab seb lub hom phiaj lub cev muaj zog ua tau raws li cov qauv tsim los yog tsis. Seb qhov kev ua tau zoo ntawm cov qauv kev sim tuaj yeem ua tau raws li cov qauv kev ntsuas. Rau cov khoom lag luam tshiab uas tsis tau tsim tawm, cov kev sib txuas hauv qab no yog qhov tseem ceeb tshwj xeeb: hauv cov khoom siv hluav taws xob semi-tiav cov khoom sib txuas, tshawb xyuas thiab txiav txim rau kev ua raws li kev tiv thaiv; nyob rau hauv kev soj ntsuam qhov txuas, ntxiv rau qhov kev tiv thaiv kev ua raws li kev kuaj xyuas, nws kuj tseem tuaj yeem ua pov thawj los ntawm qhov tsis muaj-load tam sim no Ua raws li cov windings; rau lub qhov txhab rotor motors, qhov kev ntsuam xyuas ntawm rotor qhib Circuit Court voltage los yog feem ntau hu ua transformation ratio soj ntsuam kuaj tau ncaj qha mus saib thiab txiav txim seb cov ntaub ntawv winding yog ib txwm, los yog seb tus naj npawb ntawm cov lem ntawm stator thiab rotor coils ntawm lub hom phiaj lub cev muaj zog yog. ua raws li tus qauv tsim.
Qhov tseeb, rau txhua lub cev muaj zog, nws cov ntaub ntawv kev ua tau zoo muaj qee qhov kev sib raug zoo nrog lub zog, qhov hluav taws xob, tus naj npawb ntawm cov ncej, thiab lwm yam. Cov kws tshaj lij yuav ntsuas qhov ua tau raws li lub cev muaj zog hauv cov kev sim sib txawv.
Raws li cov duab ntawm coil winding thiab txoj hauv kev ntawm cov hlua khi, nws tuaj yeem muab faib ua ob hom: centralized thiab faib.
(1) Concentrated winding
Concentrated windings yog siv nyob rau hauv salient ncej stators, feem ntau yog raug mob rau hauv lub voj voos, qhwv nrog xov paj ntaub los tsim, thiab ces embedded nyob rau hauv lub hlau tub ntxhais ntawm convex sib nqus ncej tom qab tau soaked nyob rau hauv cov xim thiab qhuav.Feem ntau, lub excitation coil ntawm commutator hom lub cev muaj zog thiab lub ntsiab ncej winding ntawm ib-theem ntxoov ntxoo ncej hom salient ncej lub cev muaj zog txais centralized winding.Concentrated windings feem ntau muaj ib lub kauj rau ib tug ncej, tab sis kuj tseem muaj cov qauv ncej, xws li ncej-hom ntxoov ntxoo ncej motors, uas siv ib kauj los ua ob tug ncej.
(2) Distributed winding
Lub stator ntawm lub cev muaj zog nrog faib winding tsis muaj convex ncej xibtes. Txhua tus ncej hlau nplaum yog tsim los ntawm ib lossis ob peb coils embedded thiab wired raws li qee txoj cai los tsim ib pawg coil. Tom qab hluav taws xob, cov hlau nplaum sib nqus ntawm cov polarities sib txawv tau tsim, yog li nws tseem hu ua hom zais ncej.Raws li kev npaj sib txawv ntawm cov hlua khi, cov kab sib txuas tuaj yeem muab faib ua ob hom: concentric thiab stacked.
● Concentric windingmuaj ob peb coils nrog cov duab zoo sib xws tab sis txawv qhov ntau thiab tsawg, uas yog embedded nyob rau hauv tib lub hauv nruab nrab txoj hauj lwm los tsim ib co coil pawg nyob rau hauv cov duab ntawm ib lo lus.Concentric windings tuaj yeem tsim biplane lossis triplane windings raws li txoj kev sib txawv.Feem ntau, stator windings ntawm ib-theem motors thiab qee qhov peb-theem asynchronous motors nrog lub zog me me lossis loj-span coils txais yuav hom no.
Laminated winding Laminated winding tshuabfeem ntau muaj cov coils ntawm tib lub duab thiab qhov loj me, ib lossis ob lub coil sab yog kos rau hauv txhua qhov, thiab lawv tau muab sib dhos thiab sib npaug ntawm ib qho los ntawm ib qho ntawm sab nraud ntawm qhov.Muaj ob hom stacked windings: ib zaug stacked thiab ob chav stacked.Tsuas yog ib qho coil sab kos rau hauv txhua qhov yog ib txheej txheej txheej winding, lossis ib leeg-stacked winding; thaum ob lub coil sab uas yog sib txawv coil pawg yog embedded nyob rau hauv txhua lub qhov, lawv muab tso rau hauv lub Upper thiab qis txheej ntawm lub qhov, uas yog ib tug ob-txheej stacked winding, los yog hu ua ob pawg winding.Raws li kev hloov pauv ntawm txoj kev sib txuas, cov kab sib txuas sib txuas tuaj yeem muab tau rau hauv hom ntoo khaub lig, concentric cross type, thiab ib txheej thiab ob txheej txheej hybrid.Tam sim no, stator windings ntawm peb-theem asynchronous motors nrog lub zog loj feem ntau siv ob txheej laminated windings; thaum lub tshuab me me feem ntau siv cov khoom siv ntawm ib txheej laminated windings, tab sis tsis tshua siv ib txheej laminated windings.
