Jenareta yemotokari.
Iyo jenareta yemotokari ndiyo huru yemagetsi emotokari, basa rayo nderekupa simba kune ese emagetsi emagetsi (kunze kwekutanga) kana injini iri kushanda zvakajairika, uye kuchaja bhatiri panguva imwe chete.
Pahwaro hweanojairwa alternator matatu-phase stator winding, wedzera nhamba yekutenderera inotenderera uye tungamira kunze kweiyo terminal, wedzera seti yematatu-chikamu bhiriji rectifier. Pakumhanya kwakadzika, iyo yekutanga mhepo uye yekuwedzera mhepo inobuda munhevedzano, uye nekumhanya kwakanyanya, chete yekutanga-nhanho-nhanho mhepo inobuda.
Kushanda musimboti
Nheyo yekushanda yealternator yose
Kana dunhu rekunze richipa simba munda unomonereka nebhurasho, magineti anogadzirwa, kuitira kuti claw pole inoiswa magineti muN pole uye S pole. Kana iyo rotor ichitenderera, iyo magineti inoyerera inochinja mune stator mhepo, zvinoenderana nemusimboti wemagetsi induction, iyo stator-nhatu-chikamu mhepo inotenderera inoburitsa alternating induced electromotive simba. Aya ndiwo magadzirirwo anoita alternator magetsi.
Iyo yekutanga mover (kureva injini) inokweva iyo DC inonakidzwa synchronous jenareta rotor kuti itenderere nekumhanya n(rpm), uye matatu-chikamu stator mhepo induction induction AC inogoneka. Kana iyo stator winding yakabatana nemagetsi mutoro, mota ine AC simba rekubuda, uye iyo AC simba inoshandurwa kuita yakananga ikozvino kubva kune inobuda terminal kuburikidza neinogadzirisa bhiriji mukati mejenareta.
Alternator yakakamurwa kuita zvikamu zviviri zve stator winding uye rotor winding, matatu-phase stator winding inogoverwa pagoko maererano nemagetsi Angle ye 120 madhigirii musiyano pakati peumwe neumwe, rotor winding inoumbwa nematanda maviri makuhwa. Apo rotor winding yakabatanidzwa kune yakananga ikozvino, inofara, uye mazamu maviri emapuranga anoita N pole uye S pole. Iyo magnetic field line inotanga kubva paN pole, inopinda mu stator core kuburikidza nemhepo gap uye inodzokera kune iri pedyo neS pole. Kana rota ichinge yatenderedzwa, mhepo inotenderera inocheka tambo yemagineti, uye inogadzira sinusoidal electromotive simba ine musiyano we120 madhigirii emagetsi Angle mumhepo ine stator, ndiko kuti, matatu-phase alternating current, uyezve kuburikidza nerectifier element inoumbwa ne diode mune yakananga ikozvino kubuda.
Kana shanduko yakavharwa, bhatiri rinotanga kupa ikozvino. Dunhu iri:
Bhatiri rakanaka → mwenje wekuchaja → regulator kubata → mafambiro emhepo → pamakumbo simbi → bhatiri harina. Panguva ino, iyo yekuchaja chiratidzo mwenje ichavhenekera nekuda kweiyo ikozvino ichipfuura.
Nekudaro, mushure mekunge injini yatanga, sezvo jenareta kumhanya kunowedzera, jenareta terminal voltage inowedzerawo. Kana simba rekubuda rejenareta rakaenzana nebhatiri voltage, kukwanisa kwe "B" kuguma uye "D" kuguma kwejenereta kwakaenzana, panguva ino, chiedza chechiratidzo chekuchaja chinodzimwa nokuti mutsauko unogona kuitika pakati pemigumo miviri ndeye zero. Inoratidza kuti jenareta iri kushanda zvakajairwa uye iyo yekunakidzwa ikozvino inopihwa nejenareta pachayo. Iyo yechitatu-phase AC electromotive simba inogadzirwa nenhatu-phase inomonereka mujenareta inogadziriswa ne diode uye inobuda yakananga ikozvino kupa simba kumutoro uye kuchaja bhatiri.
Iyo alternator inowanzo umbwa nezvikamu zvina: rotor, stator, rectifier uye end cap.
(1) Rotor
Basa re rotor nderekugadzira magineti anotenderera.
Rotor ine claw pole, joko, magnetic field winding, mhete yekuunganidza uye rotor shaft.
Mapango maviri akatsikirirwa pane rotor shaft, uye rimwe nerimwe remazinzwara maviri rine mapango matanhatu emuromo weshiri. A magnetic field winding (rotor coil) uye joko remagineti zvakarongwa mumhango ye claw pole.
Mhete yekuunganidzira ine zvindori zviviri zvemhangura zvakavharirwa kubva kune mumwe. Mhete yekuunganidza inotsikirirwa pa rotor shaft uye insulated ne shaft. Mhete mbiri dzekuunganidza dzakabatanidzwa kumigumo yese yemagnetic field winding.
Kana zvindori zviviri zvekuunganidzira zvapfuudzwa mune yakananga ikozvino (kuburikidza nebhurashi), kune ikozvino kuburikidza neiyo magineti inomonereka, uye axial magineti flux inogadzirwa, kuitira kuti imwe claw pole inobatidzwa magineti kuN pole uye imwe yacho iine magineti kuS pole, nokudaro ichiita nhanhatu mbiri dzemagineti matanda. Sezvo rotor inotenderera, inotenderera yemagineti inogadzirwa [1].
Iyo magineti yedunhu reinochinjanisa ndeiyi: joko → N danda → mhepo gap pakati pe rotor ne stator → stator → Mhepo musiyano pakati pe stator ne rotor → S pole → joko.
(2) Stator
Basa re stator ndere kubudisa alternating current.
Iyo stator ine stator core uye stator coil.
Iyo stator musimboti inoumbwa nesilicon simbi mashizha ane grooves mumhete yemukati, uye kondakita weiyo stator winding akaiswa mugororo repakati.
Iyo stator winding ine nhanho nhatu, uye iyo yechitatu nhanho mhepo inotora nyeredzi yekubatanidza kana katatu (yakakwirira simba) yekubatanidza, iyo inogona kuburitsa matatu nhanho inochinjana ikozvino.
Iyo yechitatu-chikamu inomonereka inofanirwa kukuvadzwa zvinoenderana nezvimwe zvinodiwa kuti uwane iyo yakafanana frequency, yakaenzana amplitude, chikamu musiyano we120 ° matatu-phase electromotive simba.
1. Nhambwe iri pakati pemativi maviri anoshanda ekoiri yega yega inofanirwa kuenzana nenzvimbo inogarwa negineti pole.
2. Chinhambwe chiri pakati pemapendero ekutanga emakoiri ari pedyo echikamu chimwe nechimwe chinomonereka chinofanirwa kuenzana kana kuwanda kwechinhambwe chinogarwa nemagineti mapango.
3. Mucheto wekutanga wetatu-phase winding inofanira kuparadzaniswa ne 2π + 120o magetsi Angle (nzvimbo inogarwa nepeya yemagineti matanda ndeye 360o magetsi Angle).
Mudzimba JF13 akatevedzana alternator, peya yemagineti mapango enzvimbo yenzvimbo ye6 slots (60o yemagetsi Angle per slot), magineti pole inomiririra nzvimbo yenzvimbo ye3 slots, saka nzvimbo yekupindirana kwemativi maviri anoshanda ekoiri yega yega 3 slots, chinhambwe chiri pakati pekutanga kwechikamu chimwe nechimwe chinomonereka kusvika panhanho yenhatu inotenderedza yakatarisana nenhatu. mhepo inogona kuparadzaniswa ne 2 slots, 8 slots, 3 slots. 14 slots, nezvimwewo.
(3) Mugadzirisi
Basa realternator rectifier ndere kushandura matatu-phase alternating ikozvino ye stator inomonereka kuita yakananga ikozvino. Iyo inogadziridza ye6-tube alternator ndeye-nhatu-yakazara-wave bhiriji rectifier redunhu inoumbwa ne6 silicon rectifier diode, uye matanhatu ekugadzirisa machubhu anotsikirirwa (kana welded) pamahwendefa maviri.
1. Hunhu hwemotokari silicon rectifier diodes
(1) Yakakura kushanda ikozvino, kumberi kwepakati ikozvino 50A, kuvhiya ikozvino 600A;
(2) High reverse voltage, reverse repeat peak voltage 270V, reverse non-repeat peak voltage 300V;
(3) Pane imwe chete inotungamira. Uye mamwe madhidhiyo anotungamira akanaka, mamwe diode anotungamira haana kunaka, chubhu ine mutsara wekutungamira unonzi positive chubhu, uye chubhu ine mutsara wakashata unonzi negative tube, saka rectifier diode ine positive diode uye negative diode.
(4) Kavha yekupedzisira
Chivharo chekupedzisira chinowanzo kupatsanurwa kuita zvikamu zviviri (kumberi kwekupedzisira chivharo uye kumashure kwekupedzisira chivharo), iyo inotamba basa rekugadzirisa rotor, stator, rectifier uye brashi kusangana. Iyo yekupedzisira kavha inowanzokandwa nealuminium alloy, iyo inogona kunyatso kudzivirira magineti kuvuza uye ine yakanaka kupisa kupisa kuita.
Iyo yekumashure yekupedzisira kavha inopihwa nebrashi gungano rinoumbwa nebhurashi, chibatiso chebhurashi uye chitubu chebhurashi. Basa rebhurashi ndere kuunza magetsi kuburikidza nemuunganidzi mhete mumunda unomonereka.
Kubatana pakati pemagnetic field winding (mabhurashi maviri) uye jenareta zvakasiyana, kuitira kuti jenareta inoparadzaniswa kuva mukati nekunze marudzi.
1. Internal lap iron jenareta: Jenareta ine magineti inomonereka isina kunaka bhurasho rakananga lap iron (yakanangana neimba).
2. External-clad jenareta: Jenareta umo mabhurashi ese emunda anomonereka akavharirwa kubva paimba.
Iyo yakaipa electrode (negative brush) yemagnetic field winding yekunze iron-type generator inobatanidzwa kune regulator, uye ipapo simbi inobatanidzwa mushure mokupfuura.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
