Kana dunhu rekunze richinge rasimbisa mafambiro emhepo kuburikidza nemabhurashi, magineti anogadzirwa uye claw pole inoiswa magineti muN uye S pole.Kana iyo rotor ichitenderera, iyo magineti flux inochinja mune stator mhepo, uye zvinoenderana nemusimboti we electromagnetic induction, alternating induction induction yemagetsi inogadzirwa mumatatu-chikamu mhepo ye stator.Uyu ndiwo musimboti wekugadzira magetsi alternator.
Iyo rotor yeDC-inofadza synchronous jenareta inofambiswa neiyo prime mover (kureva, injini) uye inotenderera nekumhanya n (rpm), uye matatu-chikamu stator mhepo inoita kuti AC inogona.Kana iyo stator winding yakabatana nemagetsi mutoro, mota ichange iine AC inobuda, iyo inoshandurwa kuDC nebhiriji rekugadzirisa mukati mejenareta uye inobuda kubva kune inobuda terminal.
Iyo alternator yakakamurwa kuita zvikamu zviviri: iyo stator mhepo uye rotor mhepo.Iyo yechitatu-phase stator winding inogoverwa pagoko pane yemagetsi angle ye 120 madhigirii kubva kune mumwe nemumwe, uye iyo rotor inotenderera inoumbwa nematanda maviri makuhwa.Rotor winding ine mbambo mbiri dzepango.Kana rotor ichitenderedza ichibatidzwa kuDC, inofara uye mbariro mbiri dzedanda dzinoumba N uye S matanda.Magineti mitsara yesimba inotangira paN pole, yopinda mukati me stator core kuburikidza nemhepo gap yozodzokera kune yakatarisana S pole.Kamwe rotor inotenderera, iyo rotor inotenderera inocheka mitsara yemagineti yesimba uye inogadzira sinusoidal magetsi emagetsi mune stator inotenderera ine musiyano wepakati we 120 madhigirii emagetsi ekona, kureva, matatu-phase alternating current, iyo inobva yachinjwa kuti itungamirire. ikozvino kubuda kuburikidza nerectifier element inoumbwa ne diode.
Kana shanduko yakavharwa, ikozvino inotanga kupiwa nebhatiri.Dunhu iri.
Battery positive terminal → yekuchaja chiratidzo → regulator kubata → mafambiro emhepo → latch → bhatiri reginegetsi terminal.Panguva ino, mwenje wekuchaja mwenje uchange wakabatidzwa nekuti pane ikozvino inopfuura.
Nekudaro, mushure mekunge injini yatanga, sezvo jenareta kumhanya kunowedzera, iyo terminal voltage yejenereta inokwirawo.Kana simba rekubuda rejenareta rakaenzana nebhatiri voltage, mukana we "B" uye "D" magumo ejenareta akaenzana, panguva ino, chiedza chekuchaja chakadzimwa nokuti mutsauko unogona kuitika pakati pemigumo miviri. iri zero.Iyo jenareta iri kushanda zvakajairika uye iyo yekunakidzwa ikozvino inopihwa nejenareta pachayo.Iyo yechitatu-phase AC inogoneka inogadzirwa nenhatu-chikamu kupetwa mujenareta inogadziriswa ne diode, uye ipapo simba reDC rinobuda kupa mutoro uye kuchaja bhatiri.
