Peb-theem asynchronous lub cev muaj zog rotor core yog slotted rau embed lub rotor winding los yog cam khwb cia txhuas (los yog cam khwb cia hlau txhuas, cam khwb cia tooj liab); lub stator feem ntau yog slotted, thiab nws txoj haujlwm tseem yog los embed lub stator winding.Feem ntau, lub rotor chute yog siv, vim hais tias cov txheej txheem inserting yuav nyuaj dua tom qab lub stator muaj lub chute.Lub hom phiaj ntawm kev siv chute yog dab tsi?
Muaj kev sib haum xeeb ntawm ntau zaus hauv lub cev muaj zog. Vim hais tias tus stator txais kev faib tawm luv luv windings, lub amplitude ntawm harmonic magnetic peev xwm ntawm lwm zaus tsuas yog cov hniav harmonics yog heev tsis muaj zog.Txij li cov hniav harmonic winding coefficient yog sib npaug rau qhov tseem ceeb yoj winding coefficient, cov hniav sib nqus sib nqus tsis tshua muaj kev cuam tshuam.Vim hais tias lub stator thiab rotor ntawm peb-theem asynchronous lub cev muaj zog yog slotted, lub magnetic tsis kam ntawm tag nrho cov huab cua qhov sib txawv tsis sib xws, thiab lub electromagnetic torque thiab induced electromotive quab yuam hloov raws li thaum lub cev muaj zog khiav.
Tom qab lub rotor yog slanted, tsim electromagnetic torque thiab induced electromotive quab yuam yog zoo ib yam li qhov nruab nrab tus nqi ntawm tib rotor bar tusyees faib nyob rau hauv ib lub voj voog, uas yuav ua tau zoo tsis muaj zog lub harmonic electromotive quab yuam generated los ntawm harmonic magnetic teb ntawm cov hniav, yog li ntawd. Ua kom tsis muaj zog ntxiv torque los ntawm cov chaw sib nqus sib nqus kom txo tau cov electromagnetic vibration thiab suab nrov.Txawm hais tias lub rotor skewed qhov yuav txo tau qhov tseem ceeb yoj electromotive quab yuam los ntawm lub rotor, qhov feem ntau xaiv skew slot degree yog me dua li tus ncej suab, yog li nws muaj kev cuam tshuam me ntsis ntawm kev ua tau zoo ntawm lub cev muaj zog. Yog li ntawd, me me thiab nruab nrab cam khwb cia txhuas rotor asynchronous motors Rotor chutes feem ntau yog siv.
Lub rotor blanks yog xuas nrig ntaus los ntawm cov txheej txheem ib txwm, thiab lub rotor tub ntxhais yog stacked nrog ib tug dummy ncej nrog ib tug linear oblique yuam sij. Lub oblique zawj ntawm lub rotor core kuj yog helical.
Ntawd yog, lub rotor blanks yog xuas nrig ntaus los ntawm txoj kev ib txwm, thiab rotor core yog stacked nrog ib tug cuav ncej nrog ib tug helical oblique qhov.Lub inclined zawj ntawm lub rotor core yog helical.
Qhov ntawd yog hais tias, lub tshuab xuas nrig ntaus tshuab yog nruab nrog cov khoom siv ntawm lub tshuab xuas nrig ntaus, kom txhua qhov xuas nrig ntaus rotor xuas nrig ntaus ib daim ntawv, thiab cov xuas nrig ntaus tuag txiav txav me me raws li kev xuas nrig ntaus. txoj kab nqes.Lub rotor blanks punched nyob rau hauv txoj kev no tuaj yeem xaiv tau nruab nrog lub rotor core slanted nrog lub dummy ncej nrog tus yuam sij ncaj.Hom inclined qhov rotor tub ntxhais no yog tshwj xeeb tshaj yog rau cov tooj liab bar rotor, vim hais tias lub inclined qhov ntawm lub rotor hlau core tsis yog helical, tab sis ncaj, uas yog yooj yim rau kev ntxig ntawm tooj liab tuav.Txawm li cas los xij, qhov kev txiav txim thiab kev taw qhia ntawm cov ntawv xuas nrig punched hauv txoj kev no tsis tuaj yeem thim rov qab, txwv tsis pub cov tub ntxhais laminated hlau tsis tuaj yeem ua raws li tus qauv.
Tsis muaj ntau lub tuam txhab uas muaj kev kub ceev xuas nrig ntaus tshuab nrog xuas nrig ntaus thiab inclined groove accessories, thiab nws yog ib qho nyuaj rau tsim cov kauv inclined yuam sij. Ntau tus neeg tsim khoom siv cov yawm sij hauv tiaj tus rau pawg inclined zawj rotor cores.Lub rotor qhov bar tsis tuaj yeem siv thaum lub rotor core raug xaiv nrog tus yuam sij ncaj oblique.Vim tias qhov zawj puab yog kauv rau lub sijhawm no, thiabgroove bar yog ncaj, nws yog tsis yooj yim sua kom siv ib tug ncaj zawj bar los npaj cov kauv zawj zoo.Yog tias yuav tsum tau siv cov khoom siv slotted, qhov ntev ntawm cov kab tuav yuav tsum yog me dua li cov rotor slots.Nws tsuas tuaj yeem ua haujlwm raws li tus pas nrig.Yog li ntawd, thaum xaiv lub rotor tub ntxhais nrog oblique qhov tseem ceeb, oblique qhov tseem ceeb plays ob lub luag hauj lwm ntawm skew thiab positioning.Qhov teeb meem tshwm sim thaum siv tus yuam sij linear oblique los xaiv oblique zawj rotor core yog qhov cuam tshuam ntawm helical skew ntawm punched keyway thiab ncaj skew ntawm oblique yuam sij.Ntawd yog, sab nraum nruab nrab ntawm lub rotor tub ntxhais, yuav tsum muaj kev cuam tshuam ntawm txoj kev xuas nrig ntaus thiab lub qhov tseem ceeb oblique.
