Xa isekethe yangaphandle inika amandla intshukumo evuthuzayo ngokusebenzisa iibhrashi, umhlaba wemagnethi uyaveliswa kwaye ipali yozipho yenziwa nguzibuthe kwiipali ze-N kunye ne-S.Xa i-rotor ijikeleza, i-flux yamagnetic itshintsha ngokutshintshileyo kwi-stator winding, kwaye ngokomgaqo wokungeniswa kwe-electromagnetic induction, amandla ombane wokungeniswa alternating iveliswa kwinqanaba lesithathu le-stator.Lo ngumgaqo wokwenziwa kombane wealternator.
I-rotor ye-DC-excited synchronous generator iqhutywa yi-prime mover (oko kukuthi, i-injini) kwaye ijikeleza ngesantya n (rpm), kunye nesigaba sesithathu se-stator esenza ukuba kubekho amandla e-AC.Ukuba i-stator winding ixhunywe kumthwalo wombane, i-motor iya kuba ne-AC output, eya kuguqulwa kwi-DC ngebhuloho yokulungisa ngaphakathi kwe-generator kunye nesiphumo esivela kwi-terminal ephumayo.
I-alternator ihlulwe ibe ngamacandelo amabini: i-stator winding kunye ne-rotor winding.Isigaba sesithathu se-stator sisasazwa kwiqokobhe kwi-engile yombane yee-degrees ezingama-120 ukusuka komnye nomnye, kunye ne-rotor winding iqulunqwe ngeentsipho ezimbini zepali.Ujiko lwe-rotor lubandakanya iinzipho ezimbini zepali.Xa i-rotor winding ivulwa kwi-DC, kuba nemincili kwaye iinzipho ezimbini zepali zenza i-N kunye ne-S.Imigca yemagnethi yamandla iqala kwipali engu-N, ingene kumbindi westator ngomsantsa womoya ize ibuyele kwipali engu-S ekufuphi.Nje ukuba i-rotor ijikeleze, i-rotor winding iya kunqumla imigca yemagnethi yamandla kwaye ivelise amandla ombane we-sinusoidal kwi-stator winding kunye nokwahlukana okulinganayo kwee-degrees ze-120 ze-angle yombane, oko kukuthi, inqanaba lesithathu elitshintshanayo langoku, eliguqulwa liqondise. imveliso yangoku ngokusebenzisa isiqalelo sokulungisa esenziwe ziidiode.
Xa iswitshi ivaliwe, yangoku iqala ukunikezelwa ngebhetri.Isekethe yi.
Itheminali ephosiyo ibhetri → isalathisi sokutshaja → uqhagamshelwano lomlawuli → uvuselelo oluvuselelayo → iletshi → iterminal ekhabayo yebhetri.Ngeli xesha, isibane sesalathisi sokutshaja siya kulayita kuba kukho ukugqitha ngoku.
Nangona kunjalo, emva kokuba injini iqalile, njengoko isantya sejenereyitha sikhula, i-voltage ye-terminal ye-generator nayo iphakama.Xa i-voltage ephumayo yejeneretha ilingana nombane webhetri, amandla okuba "B" kunye no "D" ekupheleni kwejeneretha ayalingana, ngeli xesha, ukukhanya kwesalathisi sokutshaja sicinyiwe ngenxa yokuba umahluko okhoyo phakathi kweziphelo zombini. ngu zero.I-generator isebenza ngokuqhelekileyo kwaye i-excitation current inikezelwa yi-generator ngokwayo.Inqanaba lesithathu le-AC elinokubakho eliveliswe yinqanaba elithathu lokujija kwijenereyitha lilungiswa yi-diode, kwaye ke amandla e-DC aphuma ukubonelela umthwalo kunye nokuhlawulisa ibhetri.
