Lapho isifunda sangaphandle sinikeza amandla ukusonteka okujabulisayo phakathi kwamabhulashi, indawo kazibuthe iyakhiqizwa futhi isigxobo sozipho sidonsa uzibuthe sibe yizigxobo zika-N no-S.Lapho i-rotor izungeza, i-flux kazibuthe ishintsha ngokushintshana ekujikeni kwe-stator, futhi ngokomgomo wokungeniswa kwe-electromagnetic, amandla kagesi okungenisa ashintshayo akhiqizwa ekujikeni kwezigaba ezintathu ze-stator.Lona umgomo wokukhiqiza ugesi we-alternator.
Irotha yejeneretha ye-DC-ejabulile ehambisanayo ishayelwa isiguquli esiyinhloko (okungukuthi, injini) futhi izungeza ngesivinini n (rpm), futhi ukuma kwe-stator kwezigaba ezintathu kudala amandla e-AC.Uma i-stator winding ixhunywe kumthwalo kagesi, injini izoba ne-AC okukhiphayo, ezoguqulelwa ku-DC ngebhuloho lokulungisa kabusha ngaphakathi kwejeneretha kanye nokuphumayo okuvela kutheminali yokuphumayo.
I-alternator ihlukaniswe izingxenye ezimbili: i-stator winding kanye ne-rotor winding.Isigaba sesithathu se-stator winding sisatshalaliswa egobolondweni nge-engeli kagesi yama-degree angu-120 ukusuka komunye nomunye, futhi ukuvuthwa kwe-rotor kwakhiwe ngezinzipho ezimbili zesigxobo.I-rotor winding iqukethe izinzipho ezimbili zezigxobo.Lapho i-rotor winding ivulwa ku-DC, iyajabula futhi izinzipho ezimbili zezigxobo zakha izigxobo zika-N kanye no-S.Imigqa yamandla kazibuthe iqala esigxotsheni sika-N, ingene kunkambo we-stator ngegebe lomoya bese ibuyela esigxotsheni sika-S esiseduze.Uma i-rotor ijikeleza, i-rotor winding izosika imigqa yamandla kazibuthe futhi ikhiqize amandla kagesi we-sinusoidal ku-stator winding enomehluko ohlangene wama-degree angu-120 we-engeli kagesi, okungukuthi, izigaba ezintathu ezishintshanayo zamanje, ezibuye zishintshwe ukuze ziqondise. okukhiphayo kwamanje ngesici sokulungisa esakhiwe ama-diode.
Uma iswishi ivaliwe, i-current iqala ukunikezwa ibhethri.Isekethe i.
Itheminali ephozithivu ibhethri → inkomba yokushaja → othintana naye nesilawuli → ukusonga okujabulisayo → i-latch → itheminali yebhethri enegethivu.Ngalesi sikhathi, ukukhanya kwenkomba yokushaja kuzokhanya ngoba kukhona ukudlula kwamanje.
Nokho, ngemva kokuba injini iqalile, njengoba ijubane lejeneretha likhula, i-voltage yokugcina ye-generator nayo iyakhuphuka.Uma i-voltage ephumayo yejeneretha ilingana ne-voltage yebhethri, amandla okuthi “B” kanye “D” ekugcineni kwejeneretha ayalingana, ngalesi sikhathi, ukukhanya kwenkomba yokushaja kuvaliwe ngoba umehluko ongaba khona phakathi kweziphetho ezimbili. nguziro.Ijeneretha isebenza ngokujwayelekile futhi amandla ashukumisayo anikezwa ijeneretha ngokwayo.Amandla ezigaba ezintathu ze-AC akhiqizwa ukujikajika kwezigaba ezintathu kujeneretha alungiswa yi-diode, bese amandla e-DC ephuma ukuze ahlinzeke ngomthwalo futhi ashaje ibhethri.
