Thaum lub sab nraud Circuit Court energizes lub excitation winding los ntawm cov txhuam hniav, ib tug magnetic teb yog generated thiab claw ncej yog magnetized rau hauv N thiab S ncej.Thaum lub rotor tig, cov sib nqus flux hloov pauv hauv stator winding, thiab raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, alternating induction hluav taws xob muaj peev xwm yog tsim nyob rau hauv peb-theem winding ntawm stator.Qhov no yog lub hauv paus ntsiab lus ntawm alternator fais fab tuag.
Lub rotor ntawm DC-excited synchronous generator yog tsav los ntawm tus thawj mover (ie, cav) thiab tig ntawm ceev n (rpm), thiab peb-theem stator winding induces AC peev xwm.Yog hais tias lub stator winding txuas nrog ib qho hluav taws xob load, lub cev muaj zog yuav muaj AC tso zis, uas yuav hloov mus rau DC los ntawm ib tug rectifier choj nyob rau hauv lub generator thiab cov zis tawm los ntawm lub output davhlau ya nyob twg.
Lub alternator muab faib ua ob ntu: stator winding thiab rotor winding.Peb-theem stator winding yog faib rau ntawm lub plhaub ntawm lub kaum sab xis ntawm 120 degrees ntawm ib leeg, thiab lub rotor winding yog tsim los ntawm ob tug ncej claws.Lub rotor winding muaj ob tug ncej claws.Thaum lub rotor winding yog tig rau DC, nws zoo siab thiab ob tug ncej claws tsim N thiab S ncej.Cov kab sib nqus ntawm lub zog pib los ntawm N ncej, nkag mus rau hauv stator core los ntawm qhov sib txawv ntawm huab cua thiab rov qab mus rau S ncej.Thaum lub rotor tig, lub rotor winding yuav txiav cov kab sib nqus ntawm lub zog thiab tsim cov hluav taws xob sinusoidal hauv stator winding nrog qhov sib txawv ntawm 120 degrees ntawm hluav taws xob lub kaum sab xis, piv txwv li, peb-theem alternating tam sim no, uas yog ces hloov mus rau ncaj qha. tam sim no tso zis los ntawm lub rectifier lub caij muaj li ntawm diodes.
Thaum lub kaw lus kaw, qhov tam sim no yog thawj zaug los ntawm lub roj teeb.Circuit Court yog.
Roj teeb zoo davhlau ya nyob twg → charging indicator → regulator contact → excitation winding → latch → battery negative terminal.Lub sijhawm no, lub teeb qhia kev them nyiaj yuav qhib vim tias muaj tam sim no dhau mus.
Txawm li cas los xij, tom qab lub cav pib, raws li lub tshuab hluav taws xob ceev nce, lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob kuj nce.Thaum cov zis hluav taws xob ntawm lub tshuab hluav taws xob sib npaug ntawm lub roj teeb voltage, lub peev xwm ntawm "B" thiab "D" kawg ntawm lub tshuab hluav taws xob sib npaug, lub sijhawm no, lub ntsuas hluav taws xob them hluav taws xob tawm vim qhov muaj peev xwm sib txawv ntawm ob kawg. yog zero.Lub tshuab hluav taws xob ua haujlwm ib txwm ua thiab cov khoom siv hluav taws xob tau muab los ntawm lub tshuab hluav taws xob nws tus kheej.Peb-theem AC muaj peev xwm tsim los ntawm peb-theem winding nyob rau hauv lub tshuab hluav taws xob yog rectified los ntawm diode, thiab ces DC lub hwj chim yog tso zis los muab lub load thiab them lub roj teeb.
