Kev faib tawm ntawm AC Peb-theem Asynchronous Tsav Windings

Ib txheej winding:
Ib txheej txheej winding yog winding nyob rau hauv uas tsuas yog ib co co zoo ntug yog embedded nyob rau hauv txhua lub stator slot, yog li nws tag nrho cov coils tsuas yog ib nrab ntawm tag nrho cov slots nyob rau hauv lub cev muaj zog. Qhov kom zoo dua ntawm ib txheej winding yog tias nws muaj tsawg dua winding coils thiab cov txheej txheem kuj yooj yim; Qhov kev siv tus nqi ntawm lub qhov yog txhim kho vim tsis muaj interlayer rwb thaiv tsev; Ib txheej txheej txheej yuav tsis muaj kev cuam tshuam rau theem kev ua txhaum, thiab lwm yam. Qhov tsis zoo yog tias lub tshuab electromagnetic waveform generated los ntawm winding tsis zoo tagnrho, cov hlau poob thiab lub suab nrov ntawm lub cev muaj zog yog qhov loj, thiab qhov pib ua haujlwm tsis zoo me ntsis. Yog li ntawd, ib txheej winding feem ntau tsuas yog siv nyob rau hauv lub peev xwm me me asynchronous motors. Ib txheej txheej windings tuaj yeem muab faib ua ntau hom winding, xws li saw winding, cross chain winding, concentric winding, thiab cross concentric winding, raws li cov duab ntawm lawv cov coils thiab kev npaj ntawm lawv qhov chaw nres nkoj.
1. chain winding
Chain winding yog tsim los ntawm ib txheej txheej coil nrog tib cov duab thiab dav, muaj npe tom qab qhov tseeb tias txhua lub kauj ntawm qhov kawg ntawm winding zoo li cov saw txuas. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias lub coil pitch ntawm ib txheej txheej saw winding yuav tsum khib, txwv tsis pub cov winding yuav tsis tuaj yeem teem rau hauv txoj kab ncaj nraim.
2. Hla saw winding
Thaum tus naj npawb ntawm cov slots hauv txhua tus ncej thiab theem ntawm cov saw hlau hlais yog ib qho khib nyiab ntau dua 2, cov saw winding tsis tuaj yeem teem caij, thiab xav tau ib qho kev sib hloov winding nrog ib lossis ob lub kauj.
3. Concentric winding
Concentric windings nyob ib puag ncig tag nrho cov coils hauv tib pawg ncej theem ib ncig ntawm tib qhov chaw.
4. Hla hom concentric winding
Thaum tus naj npawb ntawm cov slots Q nyob rau hauv txhua theem thiab theem yog tus lej txawm tias ntau dua 2, daim ntawv concentric winding tuaj yeem txais yuav.
Qhov zoo ntawm ib txheej concentric winding thiab cross concentric winding yog qhov winding thiab embedding ntawm winding yog qhov yooj yim, thaum qhov tsis zoo yog tias lub coil kawg ntev dhau lawm thiab siv ntau cov xov hlau. Tsuas yog siv qee lub sijhawm me me 2-ncej thiab 4- ncej motors, daim ntawv winding no tsis tshua muaj siv tam sim no.
Ob txheej txheej txheej winding
Ib leeg thiab ob txheej hybrid winding

Lub hnub qub kev sib txuas rau lub kaum sab xis: Tag nrho cov ntu ntu ntawm txoj kab uas hla ntawm lub hnub qub kev sib txuas tau muab faib los ntawm 1.732 sib npaug ntawm tag nrho cov ntu ntu ntawm txoj kab uas hla ntawm txoj kab uas hla ntawm lub kaum sab xis.
Lub kaum sab xis txuas rau lub hnub qub kev sib txuas: Muab tag nrho cov ntu ntu ntu ntawm cov kab hluav taws xob ntawm lub kaum sab xis ntawm thawj qhov kev sib txuas los ntawm 1.732 sib npaug ntawm tag nrho cov ntu ntu ntawm cov kab hluav taws xob ntawm lub hnub qub txuas.
Qhov tseem ceeb sib txawv ntawm lub hnub qub pob qij txha thiab kaum pob qij txha
Thaum txuas nrog lub hnub qub, cov kab hluav taws xob sib npaug yog 1.732 npaug ntawm theem voltage, thiab theem tam sim no sib npaug rau cov kab tam sim no.
Thaum cornered, theem voltage yog sib npaug rau kab voltage, thiab kab tam sim no sib npaug rau 1.732 npaug ntawm theem tam sim no.
Rau lub cev muaj zog ntawm tib lub zog, thaum txuas nrog lub hnub qub teeb tsa, lub xov hlau txoj kab uas hla yog tuab thiab muaj pes tsawg tus lem yog me me, thaum txuas nrog lub kaum sab xis ntawm lub kaum sab xis, txoj kab uas hla ntawm lub xov hlau yog nyias thiab cov xov tooj tig yog loj.
Qhov chaw hla ntawm lub kaum sab xis yog 0.58 npaug ntawm lub hnub qub sib koom. (Qhov tag nrho cheeb tsam cross-sectional ntawm cov hlau txoj kab uas hla thaum lub kaum sab sib txuas muab faib los ntawm 0.58 sib npaug rau tag nrho cov ntu ntu ntawm cov hlau kab uas hla thaum lub hnub qub txuas. lub hnub qub kev twb kev txuas los ntawm 0.58 sib npaug rau tag nrho cov hla ntu ntu ntawm cov kab kab uas hla ntawm lub kaum sab xis txuas)
Cov qauv rau kev suav cov cheeb tsam hla ntawm txoj kab uas hla: thaj tsam hla S=square ntawm txoj kab uas hla muab los ntawm 0.785
Cov kev sib txuas sab hauv ntawm lub cev muaj zog tuaj yeem muab faib ua salient thiab salient ncej. Kev sib txuas ntawm cov ncej tseem ceeb thiab cov ncej tseem ceeb yog txiav txim siab los ntawm cov khoom tsim ntawm lub cev muaj zog thiab tsis tuaj yeem hloov pauv

Disassemble lub stator core ntawm lub semi kaw lub cev muaj zog: Siv cua sov txoj kev tso lub plhaub stator upside down thiab ncua nws. Thaum qhov kub nce mus txog ib theem, maj mam co lub plhaub stator thiab nws yuav tawm tuaj.
muaj nuj nqi:
Lub cev muaj zog yuav tsum tau muab tso rau hauv av kom zoo, thiab muaj cov ntsia hlau hauv av nyob rau sab xis sab xis ntawm lub thawv sib txuas. Yog tias tsim nyog, lub cev muaj zog ko taw lossis flange kuj tuaj yeem siv los kho cov ntsia hlau rau hauv av.
Lub npe ntawm lub cev muaj zog qhia txog kev sib txuas ntawm lub hnub qub thiab daim duab peb sab. Hauv Suav teb, cov motors qis dua 3kW siv lub hnub qub kev sib txuas, thaum lub cev muaj zog tshaj 3kW siv cov duab peb sab sib txuas, thiab tsis tuaj yeem txuas tsis raug.
Lub tshuab hluav taws xob feem ntau yuav tsum tau nruab nrog cov cuab yeej tiv thaiv kev ua txhaum, xws li cov khoom siv tiv thaiv thermal, lub cev muaj zog tiv thaiv hluav taws xob, thiab lwm yam, thiab qhov teeb tsa tus nqi ntawm cov cuab yeej tiv thaiv yuav tsum raug kho raws li qhov tam sim no ntawm lub npe ntawm lub cev muaj zog. Yog tias lub load ntawm lub cev muaj zog yog qhov ruaj khov, txhawm rau tiv thaiv lub cev muaj zog zoo dua, kev teeb tsa tus nqi ntawm cov cuab yeej tiv thaiv tuaj yeem hloov kho raws li qhov ua haujlwm tam sim no ntawm lub cev muaj zog. Qhov tseeb ua haujlwm tam sim no ntawm lub cev muaj zog tuaj yeem ntsuas ncaj qha nrog lub clamp ammeter thaum lub cev muaj zog khiav hauv qab load.
Thaum qhov voltage thiab zaus ntawm cov khoom siv hluav taws xob sib txawv ntawm qhov tseem ceeb ntawm daim ntawv teev npe los ntawm ntau dua 5%, lub cev muaj zog tsis tuaj yeem lav qhov tso tawm tas li ntawm lub zog ntsuas. Kev ua haujlwm tsis tu ncua ntawm cov tshuab hluav taws xob tsis tso cai rau overload.
Lub cev muaj zog yuav tsum tsis txhob tsim cov suab tsis sib xws lossis txawv txav lossis kev vibrations thaum lub sijhawm tsis muaj kev thauj khoom lossis kev thauj khoom, thiab cov kabmob kub yuav tsum tsis txhob siab dhau.
