Amabha azacile noma amabha aphukile avame ukusetshenziswa amagama anephutha kumamothoretha e-aluminium rotor. Zombili imigoqo emincane nemigoqo ephukile ibhekisela kumabha we-rotor. Ngokwethiyori, uma i-rotor's punching slot shape, ubude bensimbi, kanye ne-slot slope kunqunywa, ama-rotor bar achazwe ngendlela evamile kakhulu. Kodwa-ke, enqubweni yangempela yokukhiqiza, izizathu ezihlukahlukene zivame ukubangela ukuthi imigoqo ye-rotor yokugcina isonteke futhi ikhubazeke, futhi ngisho nezimbobo zokuncipha zivela ngaphakathi kwemigoqo. Ezimweni ezimbi kakhulu, imigoqo ingaphuka.
Njengoba i-rotor core yenziwe ngama-rotor punching, ukuma kwe-circumferential kwenziwa yizinduku ezifakiwe ezihambisana nokushaya kwe-rotor ngesikhathi senqubo yokuqothula. Ngemuva kokuphothula, izinduku ezifakiwe ziyakhishwa bese ziphonsa i-aluminium ngesikhunta. Uma izinti eziboshiwe kanye nezikhala zixege kakhulu, izibhakela zizoba namazinga ahlukene okugudluka okuzungezayo ngesikhathi senqubo yokucwala, okuzogcina kuholele ezindaweni ezinamagagasi kuma-rotor bars, izenzakalo ze-sawtooth kuma-rotor core slots, kanye nemigoqo ephukile. Ngaphezu kwalokho, inqubo yokukhipha i-aluminium futhi iyinqubo yokuqinisa i-aluminium ewuketshezi engena kuma-rotor slots. Uma i-aluminium ewuketshezi ixubene negesi ngesikhathi sokujova futhi ayikwazi ukukhishwa kahle, ama-pores azokwakhiwa engxenyeni ethile yemishayo. Uma ama-pores emakhulu kakhulu, kuzophinde kubangele ukuphuka kwe-rotor bar.
Ukunwetshwa kolwazi - i-groove ejulile kanye nekheji eliphindwe kabiliama-asynchronous motors
Kusukela ekuhlaziyweni kokuqala kwe-cage asynchronous motor, kungabonakala ukuthi uma uqala ngokuqondile, i-current yokuqala inkulu kakhulu; lapho uqala nge-voltage encishisiwe, nakuba i-current yokuqala iyancipha, i-torque yokuqala nayo iyancipha. Ngokwezici zokwenziwa komshini wokumelana nochungechunge lwe-asynchronous motor rotor, kungabonakala ukuthi ukwanda kokumelana ne-rotor ngaphakathi kwebanga elithile kungandisa i-torque yokuqala, futhi ukwandisa ukumelana ne-rotor kuzophinde kunciphise ukuqala kwamanje. Ngakho-ke, ukumelana okukhulu kwe-rotor kungathuthukisa ukusebenza kokuqala.
Kodwa-ke, lapho i-motor isebenza ngokujwayelekile, kuthenjwa ukuthi ukumelana ne-rotor kuncane, okunganciphisa ukulahlekelwa kwethusi kwe-rotor futhi kuthuthukise ukusebenza kahle kwemoto. Kungenzeka kanjani ukuthi i-cage asynchronous motor ibe nokumelana okukhudlwana kwe-rotor lapho iqala, futhi ukumelana ne-rotor kuncipha ngokuzenzakalelayo ngesikhathi sokusebenza okujwayelekile? I-slot ejulile kanye nama-double cage asynchronous motors angafinyelela lo mgomo.
Imbobo ejulilei-asynchronous motor
I-rotor slot ye-deep slot asynchronous motor ijulile futhi incane, futhi isilinganiso sokujula kwe-slot nobubanzi be-slot ngokuvamile si-10 kuya ku-12 noma ngaphezulu. Lapho i-current igeleza kuma-rotor bars, ukugeleza kokuvuza okuxhumene naphansi kwezigxobo kukhulu kakhulu kunokuvuza okuxhumene nokuvuleka kwesikhala. Ngakho-ke, uma amabha athathwa njengenani lamakhondakta amancane ahlukaniswe ngobude be-slot axhunywe ngokuhambisana, ama-conductor amancane aseduze naphansi kwe-slot anokusabela okukhulu kokuvuza, futhi ama-conductor amancane aseduze nendawo yokuvula ane-slot encane. ukusabela kokuvuza.
Lapho i-motor iqala, ngenxa yemvamisa ephezulu ye-rotor yamanje, ukusabela kokuvuza kwemishayo ye-rotor kukhulu, ngakho-ke ukusatshalaliswa kwamanje ku-conductor ngayinye encane kuzonqunywa ngokuyinhloko ukusabela kokuvuza. Uma kukhulu ukusabela kokuvuza, kuncane okwamanje. Ngale ndlela, ngaphansi kwamandla afanayo e-electromotive atholwe yi-flux yamagnetic eyinhloko yegebe lomoya, ukuminyana kwamanje eduze nendawo ephansi ye-slot ku-conductor kuyoba kuncane kakhulu, futhi eduze ne-slot, kuyoba mkhulu. Lesi simo sibizwa ngokuthi umphumela wesikhumba wamanje. Ilingana nokwamanje okukhanywa ku-slot, ngakho-ke ibizwa nangokuthi umphumela wokuminyanisa. Umphumela womphumela wesikhumba ulingana nokunciphisa ukuphakama kanye ne-cross-section ye-conductor bar, ukwandisa ukumelana ne-rotor, futhi ngaleyo ndlela uhlangabezane nezidingo zokuqala.
Lapho ukuqala kuqediwe futhi injini isebenza ngokujwayelekile, imvamisa yamanje ye-rotor iphansi kakhulu, ngokuvamile i-1 kuya ku-3 Hz, futhi ukusabela kokuvuza kwama-rotor bars kuncane kakhulu kunokumelana ne-rotor. Ngakho-ke, ukusatshalaliswa kwamanje kuma-conductor amancane okukhulunywe ngawo ngenhla kuzonqunywa ngokuyinhloko ukumelana. Njengoba ukumelana kwe-conductor ngayinye encane kuyalingana, i-current in the bar izosatshalaliswa ngokulinganayo, futhi umphumela wesikhumba ngokuyisisekelo unyamalale, ngakho-ke ukumelana ne-rotor bar kubuyela ekumelaneni kwayo kwe-DC. Kungabonakala ukuthi ngesikhathi sokusebenza okujwayelekile, ukumelana kwe-rotor ye-deep slot asynchronous motor kungancipha ngokuzenzakalelayo, ngaleyo ndlela kuhlangabezane nezidingo zokunciphisa ukulahleka kwethusi kwe-rotor nokuthuthukisa ukusebenza kahle kwezimoto.
I-asynchronous motor enekheji eliphindwe kabili
Kunamakheji amabili ku-rotor ye-double-cage asynchronous motor, okungukuthi ikheji eliphezulu kanye nekheji engezansi. Imigoqo yekheji ephezulu inendawo encane ephambanayo futhi yenziwe ngezinto ezinokumelana okuphezulu njengethusi noma ithusi le-aluminium, futhi inokumelana okukhulu; imigoqo yekheji ephansi inendawo enkulu ye-cross-sectional futhi yenziwe ngethusi ene-resistant ephansi, futhi inokumelana okuncane. Ama-motor angama-double-cage nawo avame ukusebenzisa ama-rotor aluminium cast; kusobala ukuthi ukuvuza kwekheji engezansi kungaphezulu kakhulu kwekheji engaphezulu, ngakho-ke ukusabela kokuvuza kwekheji engezansi nakho kukhulu kakhulu kunaleyo yekheji engaphezulu.
