Ho ea kamoetsi oa motlakase oa vibration, molao-motheo oa ho sebetsa oadc motorke ho fetola matla a electromotive a chenchana a hlahisoang ke ho kenngoa ha coil ea armature hore e be matla a motlakase a motlakase ha a huloa ho tloha qetellong ea borashe ke mohatelli le ketso ea commutator ea borashe.
Ho tloha mosebetsing oa ho hlalosa: borashe ha e kenye motlakase oa dc, 'me mochine o moholo o hula lebelo la ho potoloha ka lebelo le sa fetoheng, mahlakoreng a mabeli a khoele ka ho latellana a khaola mohala oa matla a khoheli tlas'a polarity e fapaneng ea poleiti ea makenete, 'me ka ho latellana. eo induction e hlahisitseng matla a electromotive, tataiso ea matla a electromotive ho latela molao oa letsoho le letona ho tseba.
Kaha thepa ea matsoho e ntse e potoloha, hoa hlokahala hore mokhanni ea tsamaisang hona joale a behoe tlas'a li-coil edges ab le CD sebakeng sa makenete ho khaola mela ea matla tlas'a lipalo tsa N le S, le hoja tataiso ea matla a motlakase a susumelitsoeng ke motlakase. moeling o mong le o mong oa khoele le ho pholletsa le khola e fapanyetsana.
The induced electromotive force in the coil is alternating electromotive force , ha matla a electromotive qetellong ea borashe A le B ke A ka ho toba hona joale matla a motlakase.
Hobane, ts'ebetsong ea ho potoloha ha lihlomo, ho sa tsotelehe hore na sehlomo se reteleha hokae, ka lebaka la ts'ebetso ea commutator le brush commutator, matla a electromotive a susumetsoang ke borashe A ka lehare la commutator e lula e le matla a electromotive pheletsong ea coil e sehang n. - pole ea magnetic field line. Ka hona, borashe A kamehla e na le A positive polarity.
Ka mokhoa o ts'oanang, borashe B kamehla e na le polarity e mpe, kahoo ho fela ha borashe ho ka lebisa ho matla a motlakase a motlakase a tataiso e sa feleng empa boholo bo sa tšoaneng. dc electromotive force e ka fumanoa.
Ena ke tsela eo dc motors e sebetsang ka eona. E boetse e bontša hore sub - dc motor ha e le hantle ke jenereithara ea ac e nang le commutator.
Ho latela kenyelletso ea baetsi ba likoloi tsa vibration, ho tloha maemong a mantlha a motlakase, mochini oa dc ha e le hantle o ka sebetsa joalo ka motlakase, hape o ka tsamaisoa joalo ka jenereithara, empa lithibelo li fapane.
Lipheletsong tse peli tsa borashe tsa koloi ea dc, eketsa voltage ea dc, kenya matla a motlakase ka har'a armature, tlhahiso ea matla a mochini ho tsoa mochining oa motlakase, mochini o hulang oa tlhahiso, matla a motlakase ho matla a mochini ebe o fetoha enjene;
Haeba "prime mover" e sebelisetsoa ho hula armature ea dc motor, 'me brush e sa kenye dc voltage, joale ho fela ha brush ho ka lebisa ho dc electromotive force e le mohloli oa matla oa dc, o ka ntšang matla a motlakase.
