Generator yezimoto.
I-generator yemoto ingukuhlinzekwa kwamandla okuphambili kwemoto, umsebenzi wayo ukuhlinzeka ngamandla kuyo yonke imishini kagesi (ngaphandle kwe-Starter) lapho injini isebenza ngokujwayelekile, bese ikhokhisa ibhethri ngasikhathi sinye.
Ngokwesisekelo i-alternator ejwayelekile i-Stator Stator Winding, khulisa isibalo sokushintsha umoya futhi uhole i-terminal, engeza iqoqo lesigaba esinezigaba ezintathu zebhuloho. Ngejubane eliphansi, umoya oyisisekelo kanye nomoya ongenwe nguchungechunge ngochungechunge, nangejubane elikhulu, kuphela ukuvela kwesigaba ezintathu kuphela okuphumayo.
Umgomo Wokusebenza
Umgomo osebenzayo we-alternator yonke
Lapho umjikelezo wangaphandle enika amandla insimu evutha ibhulashi, kwakhiqizwa amandla kazibuthe, ukuze isigxobo se-claw sibaziswe esigxotsheni nesigxobo sesigxobo. Lapho i-rotor ijikeleza, i-flux kazibuthe ngokuhlukile kushintshana ngokufudumala kwe-stator, ngokuya ngesimiso sokungeniswa kwe-electromagnetic, i-stator isitebhisi esisesigabeni esinezinyathelo ezintathu izokhiqiza ukushintshanisa amandla e-electromotive. Le ndlela umuntu okhipha ugesi.
I-Prime Mover (okusho injini) idonsa i-DC evumelanayo ye-generator rotor yokuvumelanisa ukujikeleza ngejubane n (Rpm), kanye nesitatimende sesitayela esinezitayela ezintathu ezivuthayo Uma i-Stator Winding ixhumeke kumthwalo kagesi, iMoto inomphumela wamandla we-AC, futhi amandla e-AC aguqulwa abe yi-terminal eqondile kusuka ku-terminal yokukhipha ngaphakathi kwe-generator.
I-Alternator ihlukaniswe izingxenye ezimbili zokuphambanisa izitaki kanye ne-rolor winding, i-stator yesitayela sesitayela esisatshalaliswa egobolondweni ngokuya nge-angle kagesi umehluko we-120 degrees phakathi komunye nomunye, i-rotor winding yakhiwa ama-pole ama-pole. Lapho i-rotor i-winding ixhunyiwe ukuqondisa kwamanje, kujabulile, futhi lezi zigxobo zombili ze-pole zakha i-N Pole nesigxobo. Umugqa wamandla kazibuthe uqala kusuka ku-N Pole, engena kwi-Stator Core ngokusebenzisa igebe lomoya bese ubuyela esigxotsheni esiseduze. Lapho i-rotor ijikelezwe, i-rotor winding izosika umugqa wamandla kazibuthe, futhi ikhiqize amandla we-sinosoidal nge-angle kagesi ka-120 ku-degrees kagesi e-stator, okungukuthi, esigabeni esishintshani esisebenza njengamanje, bese ngento elungiselelwe ama-diode aqukethe imiphumela eqondile yamanje.
Lapho i-switch ivaliwe, ibhethri kuqala linikeza okwamanje. Umjikelezo ngu:
Ibhethri eliqondile → Ukushaja Ukukhanya → Oxhumana naye Wama-Musicting → Ukuxoxisana Ngalesi sikhathi, ukukhanya kwesikhombisi sokushaja kuzokhanya ngenxa yokudlula kwamanje.
Kodwa-ke, ngemuva kokuthi injini iqale, njengoba ijubane le-generator lenyuka, i-generator terminal voltage nayo iyanda. Lapho ukukhishwa kwe-voltage kwe-generator kulingana nogesi webhethri, amandla okuphela kwe- "B" kanye ne- "D" yokuphela kwe-generator kuyalingana, ngalesi sikhathi, ukukhanya kwesikhombisi senkokhiso kuyacishwa ngoba umehluko ongaba khona phakathi kwalezi zinhlamvu ezimbili. Ibonisa ukuthi i-generator isebenza ngokujwayelekile futhi i-exparitation yamanje ihlinzekwa yi-generator uqobo. Amandla we-electromotive amathathu e-AC akhiqizwa yi-Worning yesigaba ezintathu ku-generator alungiswa yi-diode nemiphumela eqondile eqondile ukuhlinzeka amandla emthwalweni bese kushaja ibhethri.
I-alternator ngokuvamile yakhiwa izingxenye ezine: rotor, i-stator, ukulungisa inqubo nokuphela.
(1) rotor
Umsebenzi we-rotor ukukhiqiza amandla kazibuthe ajikelezayo.
I-rotor iqukethe isigxobo se-claw, ijoka, i-posing yamandla kazibuthe, indandatho yokuqoqa kanye ne-rotor shaft.
Izigxobo ezimbili ezibunjiwe zicindezelwa emgodini we-rotor, futhi izigxobo zombili ezimbili zinezigxobo eziyisithupha zezinyoni-beak. I-Winking Ford Great Poling (COOROR COIL) kanye nejoka kazibuthe lihlelwe emgodini wesigxobo se-claw.
I-Collector Right iqukethe izindandatho zethu zethusi zethusi ezifakwe komunye nomunye. Indandatho yokuqoqa icindezelwe ku-rotor shaft futhi ifakwe nge-shaft. Izindandatho eziqoqiwe zombili zixhumeke kuzo zombili iziphetho zomoya kazibuthe.
Lapho izindandatho zezinqola ezimbili zidluliselwa kumanje (ngebhulashi), kukhiqizwa kwamanje ngomoya kazibuthe, futhi kukhiqizwa i-axial Magnetic Flux, ngakho-ke i-Claw Pole ikhishwe esigxotsheni, ngaleyo enye ibeka amabhande ayisithupha okuxhumeka kwezigxobo. Njengoba i-rotor ijikeleza, amandla kazibuthe ajikelezayo adalwe [1].
Umjikelezo kazibuthe we-alternator uthi: ijoka → n pole → igebe lomoya phakathi kwe-rotor ne-stator → Isitayela → igebe →
(2) Isitebhisi
Umsebenzi we-stator ukukhiqiza ukushintshana kwamanje.
Isitadlo siqukethe umnyombo we-stator kanye ne-stator coil.
I-Stator Core yakhiwa ngamashidi ensimbi e-silicon ane-grooves kwindandatho yangaphakathi, kanye nomqhubi we-stator winding ufakwa emgodini we-core.
I-Stator Winding inezigaba ezintathu, futhi isigaba ezintathu esivumayo simamukeli uxhumano lwenkanyezi noma unxantathu (amandla aphezulu), ongakhiqiza isigaba ezintathu esishintshashintshayo samanje.
Umoya wesigaba ezintathu kufanele ube nesilonda ngokuya ngezidingo ezithile ukuze uthole imvamisa efanayo, amplitude elilinganayo, umehluko we-120 ° ama-electromotive Force.

Kwi-APP ye-HOSP yasekhaya yasekhaya ye-JF13, i-pair of account kazibuthe yesikhundla esingu-6 Slots (60o engela kagesi ngesigaba se-3 Slots esisezingeni eliphakeme se-3 Slots, i-Standation Slots yesigaba se-COIL, 8 Slots, 3 Slots. 14 Slots, njll.
(3) uqonde kahle
Iqhaza le-alternator rectifier ukuguqula isigaba esingu-3 sishintshana ngaphandle kwe-Stator Wishing ibe manje. Umbiko we-6-tube alterrator iyingxenye yesiko eliphelele eligcwele le-wave-wave ibhuloho elihlanganisiwe le-6 silicon rexifier diodes, kanye namashubhu axegayo ayi-6 acindezelwe ngokulandelana (noma amapuleti) ngamapuleti amabili.
1. Izici ze-automotive silicon rexifier diodes

(3) Kunomthofu owodwa kuphela. Futhi ezinye izithako ze-diode zinezinhlelo ezithile, ezinye izinto ze-diode azilungile, i-tube enomugqa omuhle ibizwa ngokuthi ishubhu elihle, bese ishubhu enomthelela omubi ibizwa nge-dune engemihle, i-diode emihle.
(4) ikhava yokuphela
Isembozo sokugcina sihlukaniswe izingxenye ezimbili (ikhava yokuphela kwangaphambili kanye nesembozo sokugcina esingemuva), esidlala indima yokulungisa i-rotor, i-stator, inqubo yokuxubha kanye nomhlangano. Isembozo sokugcina sivame ukusakazwa nge-aluminium alloy, esingavimba ngempumelelo ukuvuvukala kwamabuthe futhi sinokusebenza okuhle kokushisa kokushisa.
Isembozo sokuphela sangemuva sinikezwa umhlangano webhulashi owakhiwa ibhulashi, umnikazi webhulashi nentwasahlobo yebhulashi. Iqhaza lebhulashi ukwethula ukunikezwa kwamandla ngendandatho yomqoqi emkhakheni wensimu.
Ukuxhumana phakathi komoya kazibuthe (amabhulashi amabili) futhi i-generator yehlukile, ukuze i-generator ihlukaniswe ngezindlela zangaphakathi nezangaphandle
1. I-Iron Generator yangaphakathi ye-LAP Iron: I-generator enomsika wamazibuthe odonsa ibhulashi elibi elibi ngokuqondile i-iron iron (exhunywe ngqo ezindlini).
2. I-External-Clad Generator: Ijenerali lapho womabili amabhulashi e-finding avela khona ezindlini.
I-electrode engemihle (ibhulashi elingelona elingelona elingesihle) lokususwa kwangaphandle kwamandla kagesi we-iron-iron generator lixhumeke kuMlawuli, bese i-Iron ixhunyiwe ngemuva kokudlula.
