Ha potoloho e ka ntle e matlafatsa tšimo e kenang ka har'a borashe, ho hlahisoa matla a khoheli, e le hore palo ea claw e be le makenete ho N pole le S pole. Ha rotor e potoloha, matla a khoheli a fetoha ka tsela e fapaneng ho matsoelintsoeke a stator, ho latela molao-motheo oa ho kenella ka motlakase, stator ea mekhahlelo e meraro e tla hlahisa matla a motlakase a feto-fetohang. Ena ke tsela eo alternator e hlahisang motlakase ka eona.
The prime mover (ke hore enjene) hula DC excited synchronous jenereithara rotor ho potoloha ka lebelo n(rpm), le mekhahlelo e meraro stator matsoelintsoeke induction AC bokgoni. Haeba stator winding e hokahane le mojaro oa motlakase, enjene e na le matla a AC, 'me matla a AC a fetoloa hona joale ho tloha setsing sa tlhahiso ka borokho bo lokisang kahare ho jenereithara.
Alternator e arotsoe ka likarolo tse peli tsa stator matsoelintsoeke le rotor matsoelintsoeke, tse tharo-mohato stator matsoelintsoeke e ajoa ka khetla ho ea ka Angle motlakase ea likhato 120 phapang pakeng tsa mong le e mong tse ling tse, rotor matsoelintsoeke e entsoe ka tse peli pole claws. Ha rotor winding e hokahane le hona joale ka ho toba, e thaba, 'me linala tse peli tsa pole li theha N pole le S pole. Mohala oa magnetic field o qala ho tloha N pole, o kena mokokotlong oa stator ka lekhalo la moea ebe o khutlela ho S pole e haufi. Hang ha rotor e pota-potiloe, matsoelintsoeke a rotor a tla khaola mohala oa matla a khoheli, 'me a hlahise matla a motlakase a sinusoidal ka phapang ea likhato tse 120 tsa Angle ea motlakase ho stator matsoelintsoeke, ke hore, mekhahlelo e meraro e fapanyetsanang hona joale, ebe ka karolo ea rectifier e entsoeng. ea diode ho tlhahiso e tobileng ea hona joale.
Ha sesebelisoa se koetsoe, betri e fana ka ea hona joale pele. Potoloho ke:
Betri e ntle → lebone le tjhajang → lebitso la selaolo → phepelo e tsosang takatso → aene ea seropeng → betri ha e sebetse. Ka nako ena, lebone la ho tjhaja le tla bonesa ka lebaka la ho feta ha hajoale.

Alternator ka kakaretso e entsoe ka likarolo tse 'ne: rotor, stator, rectifier le end cap.
(1) Rothara
Mosebetsi oa rotor ke ho hlahisa matla a khoheli a potolohang.
Rotor e na le palo ea claw, joko, matla a khoheli a pota-potileng, selikalikoe sa pokello le rotor shaft.
Lipalo tse peli tsa manala li hatelloa holim'a mofeng oa rotor, 'me e 'ngoe le e 'ngoe ea lipalo tse peli tsa claw e na le lipalo tse tšeletseng tsa makenete tsa melomo ea nonyana. Maqhubu a matla a khoheli (rotor coil) le joko ea makenete li hlophisitsoe ka har'a mokoloko oa palo ea claw.
Lesale la mokekelli le na le mehele e 'meli ea koporo e insulated ho tloha ho e mong. Lesale la mokekelli le hatelloa holim'a sefate sa rotor ebe le kenngoa ka shaft. Mehele e 'meli ea pokello e hokahane lintlheng tse peli tsa matsoelintsoeke a matla a khoheli.
Ha mehele e 'meli ea mokelli e fetisetsoa ho motlakase o tobileng (ka borashe), ho na le hona joale ka matla a khoheli a phallang,' me axial magnetic flux e hlahisoa, e le hore palo e le 'ngoe ea claw e matlafatsoe ho N pole 'me e' ngoe e be le magnetized. ho ea ho S pole, kahoo ho etsa lipara tse tšeletseng tsa lipalo tsa makenete tse tsoelipanang. Ha rotor e ntse e potoloha, ho bōptjoa matla a khoheli a potolohang [1].
Potoloho ea makenete ea alternator ke: joko → N pole → lekhalo la moea pakeng tsa rotor le stator → stator → Lekhalo la moea pakeng tsa stator le rotor → S pole → joko.
(2) The stator
Mosebetsi oa stator ke ho hlahisa motlakase o mong.
Stator e na le mokokotlo oa stator le coil ea stator.
Mokotla oa stator o entsoe ka lishiti tsa tšepe tsa silicon tse nang le li-grooves ka har'a selikalikoe se ka hare, 'me mokhanni oa stator winding o kenngoa ka har'a groove ea mantlha.
Maqhubu a stator a na le mekhahlelo e meraro, 'me matsoelintsoeke a mekhahlelo e meraro a amohela khokahano ea linaleli kapa khokahanyo ea kgutlotharo (matla a phahameng), e ka hlahisang methati e meraro e fapanyetsanang hona joale.
Maqhubu a mekhahlelo e meraro a tlameha ho etsoa leqeba ho ea ka litlhoko tse itseng e le hore a fumane maqhubu a tšoanang, amplitude e lekanang, phapang ea karolo ea 120 ° ea mekhahlelo e meraro ea matla a motlakase.
1. Sebaka pakeng tsa mahlakore a mabeli a sebetsang a coil ka 'ngoe e lokela ho lekana le sebaka se nkiloeng ke palo ea makenete.
2. Sebaka se pakeng tsa mathōko a ho qala a li-coil tse haufi tsa mohato o mong le o mong oa matsoelintsoeke e lokela ho lekana kapa ho feta sebaka se nkiloeng ke lipalo tsa makenete.
3. Moeli oa ho qala oa mekhahlelo e meraro o lokela ho aroloa ke 2π + 120o Angle ea motlakase (sebaka se nkiloeng ke lipalo tsa magnetic ke 360o Angle ea motlakase).
Ka har'a li-alternator tsa lehae tsa JF13, palo ea lipalo tsa makenete e nka sebaka sa sebaka sa 6 slots (60o Angle ea motlakase ka sekotjana), palo ea matla a khoheli e ikarabella bakeng sa sebaka sa li-slots tse 3. khoele e 'ngoe le e' ngoe e na le li-slots tse 3, sebaka se pakeng tsa moeli o qalang oa mokhahlelo o mong le o mong o haufi le li-slots tsa 6, moeli oa qalo oa mekhahlelo e meraro. matsoelintsoeke a ka aroloa ke 2 slots, 8 slots, 3 slots. 14 slots, joalo-joalo.
(3) Moloki
Mosebetsi oa alternator rectifier ke ho fetola motlakase oa mekhahlelo e meraro oa stator hore e be hona joale ka ho toba. Rectifier ea 6-tube alternator ke potoloho ea borokho bo felletseng ba mekhahlelo e meraro e entsoeng ka li-diode tse 6 tsa silicon, 'me li-tubes tse 6 li hatelloa ka ho latellana (kapa li cheselitsoe) lipoleiting tse peli.
1. Litšobotsi tsa li-diode tsa likoloi tsa silicon rectifier
(1) E kholo ea ho sebetsa hona joale, ho ea pele ka karolelano ea 50A, ho phahama ha 600A hona joale;
(2) High reverse voltage, reverse pheta peak voltage 270V, reverse non-repeat peak voltage 300V;
(3) Ho na le moetapele a le mong feela. 'Me tse ling tsa li-diode lead li ntle, tse ling tsa li-diode lead ha li ntle, tšupu e nang le mothapo o nepahetseng o bitsoa "positive tube", 'me thapo e nang le mola o mobe o bitsoa negative tube, kahoo rectifier diode e na le "positive diode". diode e mpe.
(4) Sekoahelo sa ho qetela
Sekoahelo sa ho qetela se arotsoe ka kakaretso likarolo tse peli (sekoahelo se ka pele le sekoahelo se ka morao), se phethang karolo ea ho lokisa rotor, stator, rectifier le brush assembly. Sekoahelo sa ho qetela hangata se lahleloa ka motsoako oa aluminium, o ka thibelang ho tsoa ha makenete ka nepo mme o na le ts'ebetso e ntle ea ho senya mocheso.
Sekoahelo se ka morao se fanoa ka kopano ea borashe e entsoeng ka borashe, sets'oants'o sa borashe le spring spring. Mosebetsi oa borashe ke ho hlahisa phepelo ea motlakase ka selikalikoe sa mokekelli ho ea lebaleng la matsoelintsoeke.
Khokahano pakeng tsa maqhubu a matla a khoheli (mabosheane a mabeli) le jenereithara e fapane, e le hore jenereithara e arotsoe ka mefuta ea kahare le kantle.
1. Internal lap tšepe jenereithara: Jenereithara le matla a khoheli matsoelintsoeke garaga negative ka ho toba lap tšepe (ho ho toba ho matlo).
2. Jenereithara e apereng ka ntle: Jenereithara eo ho eona borashe ka bobeli ba matsoelintsoeke a lebala a kentsoeng ka har'a ntlo.
Electrode negative (negative borashe) ea matla a khoheli matsoelintsoeke ea ka ntle tšepe-mofuta jenereithara e amana le regulator, 'me joale tšepe e amana ka mor'a ho feta.
Haeba u batla ho tseba haholoanyane, tsoela pele ho bala lingoliloeng tse ling sebakeng sena sa marang-rang!
Ka kopo, re letsetse haeba u hloka lihlahisoa tse joalo.
Zhuo Meng Shanghai Auto Co., Ltd. e ikemiselitse ho rekisa likarolo tsa koloi tsa MG&MAUXS tse amoheloang ho li reka.
