Raws li covvibration motor manufacturers, lub hauv paus ntsiab lus ntawm kev ua haujlwmdc zogyog los hloov lub alternating electromotive quab yuam generated los ntawm induction nyob rau hauv lub armature coil mus rau hauv ib tug ncaj qha tam sim no electromotive quab yuam thaum nws yog kos los ntawm txhuam kawg los ntawm lub commutator thiab lub commutator kev txiav txim ntawm txhuam.
Los ntawm cov commutator ua hauj lwm los piav qhia: tus txhuam tsis ntxiv dc voltage, nrog tus prime mover rub lub armature counterclockwise tsis tu ncua kev sib hloov ceev, ob sab ntawm lub coil feem txiav cov magnetic quab yuam kab nyob rau hauv lub sib txawv polarity ntawm lub magnetic ncej, thiab nyob rau hauv lub commutator. uas lub induction generated electromotive quab yuam, electromotive quab yuam kev taw qhia raws li txoj cai tes los txiav txim.
Txij li thaum lub armature rotates tsis tu ncua, nws yog tsim nyog rau lub tam sim no-nqa conductor yuav tsum tau rau coil npoo ab thiab CD nyob rau hauv ib tug sib nqus teb kom alternately txiav cov kab ntawm quab yuam nyob rau hauv lub N thiab S ncej, txawm hais tias cov kev taw qhia ntawm induced electromotive quab yuam. ntawm txhua lub coil ntug thiab thoob plaws lub kauj yog alternating.
Lub induced electromotive quab yuam nyob rau hauv lub kauj yog ib tug alternating electromotive quab yuam, thaum lub electromotive quab yuam nyob rau hauv kawg ntawm txhuam A thiab B yog A ncaj qha tam sim no electromotive quab yuam.
Vim hais tias, nyob rau hauv tus txheej txheem ntawm armature rotation, txawm nyob qhov twg lub armature tig, vim hais tias ntawm lub commutator thiab txhuam commutator kev txiav txim, lub electromotive quab yuam induced los ntawm txhuam A los ntawm lub commutator hniav yog ib txwm lub electromotive quab yuam ntawm ntug ntawm lub coil txiav lub n. -pole magnetic teb kab. Yog li ntawd, txhuam A ib txwm muaj qhov zoo polarity.
Nyob rau hauv tib txoj kev, txhuam B ib txwm muaj qhov tsis zoo polarity, yog li cov txhuam hniav kawg tuaj yeem ua rau cov mem tes electromotive quab yuam ntawm qhov kev taw qhia tas li tab sis qhov sib txawv ntawm qhov loj.Yog tias tus naj npawb ntawm cov coils hauv qab txhua tus ncej yog nce, cov qib ntawm cov mem tes vibration tuaj yeem txo thiab dc electromotive quab yuam tuaj yeem tau txais.
Qhov no yog li cas dc motors ua hauj lwm.Nws kuj qhia tau hais tias lub sub - dc lub cev muaj zog yog tiag tiag ac generator nrog commutator.
Raws li cov kev taw qhia ntawm kev co lub cev muaj zog manufacturers, los ntawm qhov yooj yim electromagnetic teeb meem, ib tug dc lub cev muaj zog nyob rau hauv lub hauv paus ntsiab lus yuav ua hauj lwm raws li ib tug lub cev muaj zog khiav, kuj yuav khiav raws li ib tug generator, tab sis cov kev txwv yog txawv.
Ntawm ob txhuam kawg ntawm dc lub cev muaj zog, ntxiv dc voltage, input hluav taws xob lub zog rau hauv lub armature, txhua yam muaj zog tso tawm los ntawm lub cev muaj zog, rub cov tshuab tsim khoom, lub zog hluav taws xob rau hauv lub tshuab hluav taws xob thiab ua lub cev muaj zog;
Yog hais tias tus prime mover yog siv los rub lub armature ntawm dc lub cev muaj zog, thiab txhuam tsis ntxiv dc voltage, ces tus txhuam kawg tuaj yeem ua rau dc electromotive quab yuam ua lub zog dc, uas tuaj yeem tsim hluav taws xob hluav taws xob. Lub cev muaj zog hloov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob thiab dhau los ua lub tshuab hluav taws xob.
Lub hauv paus ntsiab lus uas tib lub cev muaj zog tuaj yeem ua haujlwm raws li lub tshuab hluav taws xob lossis lub tshuab hluav taws xob.In motor theory nws hu ua txoj cai thim rov qab.
