Ngokuthandwa kakhulu kwamandla kagesi aguquguqukayo, inkinga yokuqala yama-motor isibe lula ukuyixazulula, kodwa ngezinsiza zamandla ezivamile, ukuqalai-rotor yekheji lesikweleAma-motor angenawo ugesi abelokhu eyinkinga. Kusukela ekuhlaziyweni kokusebenza kokuqala nokusebenza kwama-motor angenawo ugesi, kungabonakala ukuthi ukuze kwandiswe i-torque yokuqala futhi kuncishiswe ugesi ngesikhathi sokuqala, ukumelana kwe-rotor kuyadingeka kube kukhulu; kuyilapho lapho imoto isebenza, ukuze kuncishiswe ukulahleka kwethusi kwe-rotor futhi kuthuthukiswe ukusebenza kahle kwemoto, ukumelana kwe-rotor kudingeka kube kuncane; lokhu kusobala ukuthi kuyaphikisana.
Kuma-motor e-wound rotor, njengoba i-resistor ingaxhunywa ngochungechunge ngesikhathi sokuqala bese isuswa ngesikhathi sokusebenza, le mfuneko ihlangatshezwa kahle. Kodwa-ke, i-wound rotor asynchronous motor inesakhiwo esiyinkimbinkimbi, izindleko eziphakeme, kanye nokugcinwa okungahambi kahle, okunciphisa ukusetshenziswa kwayo ngezinga elithile; lokhu kushukumisela abantu ukuthi baqale ngesimo se-rotor slot sekheji le-squirrel.injini engavumelanifuthi zama ukusebenzisa "umphumela wesikhumba" ukufeza inhloso yokumelana kokuqala okukhulu kanye nokumelana okuncane ngesikhathi sokusebenza. Ama-rotor motors e-deep slot kanye ne-double squirrel cage analo msebenzi wokuqala. Namuhla, ake sixoxe ngama-rotor motors e-deep slot.
Injini ejulile engenazo izinsimbi
Ukuze kuthuthukiswe umphumela wesikhumba, ukuma kwesikhala se-deep slot asynchronous motor rotor kujule futhi kuncane, futhi isilinganiso sokujula kwesikhala nobubanzi besikhala sisebangeni lika-10-12. Lapho ugesi udlula emigoqweni ye-rotor, i-leaking flux exhumene nephansi lemigoqo inkulu kakhulu kune-leaking flux exhumene nesikhala. Ngakho-ke, uma imigoqo ibhekwa njengenani labaqhubi abancane abahlukaniswe ngokuphakama kwesikhala okuxhunywe ngokulingana, abaqhubi abancane abaseduze nephansi lesikhala banokusabela okukhulu kokuvuza, futhi lapho besondela ekuvulekeni kwesikhala, kulapho ukusabela okuncane kokuvuza.
Ekuqaleni, njengoba imvamisa yamanje ye-rotor iphezulu futhi ukusabela kokuvuza kukhulu, ukusatshalaliswa kwamanje kumqhubi ngamunye omncane kuzoncika ekuphenduleni kokuvuza. Uma ukusabela kokuvuza kukhulu, kulapho ukusabela kokuvuza kuncane khona. Ngale ndlela, ngaphansi kwesenzo samandla afanayo abangelwa ukugeleza okuyinhloko kwamagnetic kwegebe lomoya, ubuningi bamanje eduze kwesisekelo sesikhala emabhawini buzoba buncane kakhulu, futhi lapho kusondela ekuvulekeni kwesikhala, ubuningi bamanje bukhulu kakhulu.
Ngenxa yomphumela wesikhumba, ngemva kokuba iningi lamandla kagesi licindezelwe engxenyeni engenhla yebha yomqhubi, indima yebha yomqhubi phansi kwesikhala incane kakhulu, okulingana nokunciphisa ukuphakama kanye nengxenye yebha yomqhubi, ngakho ukumelana kwe-rotor kuyanda, futhi kuhlangabezana nesidingo sokumelana okukhulu ekuqaleni. Lapho imoto iqalwa futhi imoto isebenza ngokujwayelekile, ngenxa yemvamisa ephansi yamandla kagesi kagesi kagesi, ukusabela kokuvuza kokujikeleza kwe-rotor kuncane kakhulu kunokumelana kwe-rotor, ngakho-ke ukusatshalaliswa kwamandla kagesi kubaqhubi abancane okukhulunywe ngabo ngenhla kuzonqunywa kakhulu ukumelana.
Njengoba ukumelana komqhubi ngamunye omncane kufana, ugesi osebha yomqhubi uzosatshalaliswa ngokulinganayo, ngakho-ke umphumela wesikhumba uyanyamalala ngokuyisisekelo, futhi ukumelana komugqa womqhubi we-rotor kuba kuncane futhi, eduze nokumelana kwe-DC. Kungabonakala ukuthi ukusebenza okuvamile kokumelana kwe-rotor kuzoncipha ngokuzenzakalelayo, ngaleyo ndlela kuhlangatshezwane nomphumela wokunciphisa ukulahleka kwethusi nokuthuthukisa ukusebenza kahle.
Uyini umphumela wesikhumba?
Umphumela wesikhumba ubizwa nangokuthi umphumela wesikhumba. Lapho ugesi oshintshashintshayo udlula kumqhubi, ugesi uzogxila ebusweni bomqhubi. Lesi simo sibizwa ngokuthi umphumela wesikhumba. Lapho ugesi noma i-voltage iqhutshwa kumqhubi onama-electron amaningi, uzohlangana ebusweni bomqhubi ophelele esikhundleni sokusatshalaliswa ngokulinganayo endaweni enqamulayo yomqhubi wonke.
Umphumela wesikhumba awuthinti nje kuphela ukumelana kwe-rotor, kodwa futhi nokusabela kokuvuza kwe-rotor. Kusukela endleleni yokuvuza kwe-slot, kungabonakala ukuthi ugesi odlula ku-conductor omncane udala kuphela ukuvuza okuvela ku-conductor omncane kuya ku-slot, kodwa hhayi kusuka ku-conductor omncane kuya phansi kwe-slot, ngoba lokhu kokugcina akunaxhumano nogesi. Ngale ndlela, kugesi ofanayo, lapho kusondela phansi kwe-slot, kukhiqizwa ukuvuza okuningi, futhi lapho kusondela ku-slot, kukhiqizwa ukuvuza okuncane. Kungabonakala ukuthi lapho umphumela wesikhumba ucindezela ugesi ku-conductor kuya ku-slot, ukuvuza kwe-slot okukhiqizwa ugesi ofanayo kuyancishiswa, ngakho-ke ukusabela kokuvuza kwe-slot kuyancishiswa. Ngakho-ke, umphumela wesikhumba wandisa ukumelana kwe-rotor futhi unciphisa ukusabela kokuvuza kwe-rotor.
Amandla omphumela wesikhumba ancike emvamisa yamanje we-rotor kanye nosayizi wesikhala. Uma imvamisa iphakeme futhi isikhala sijula, umphumela wesikhumba uzoba mkhulu kakhulu. Ku-rotor efanayo, uma imvamisa ihlukile, umphumela wesikhumba uzohluka, futhi amapharamitha e-rotor nawo azohluka. Ngenxa yalokhu, ukumelana kwe-rotor kanye nokusabela kokuvuza ngesikhathi sokusebenza okuvamile nokuqala kufanele kuhlukaniswe ngokuqinile futhi akunakudideka. Kumvamisa efanayo, umphumela wesikhumba wama-rotor ajulile e-groove unamandla kakhulu, kodwa umphumela wesikhumba nawo unethonya elithile kuma-rotor e-squirrel cage ajwayelekile. Ngakho-ke, ngisho naku-rotor ye-squirrel-cage enesakhiwo esijwayelekile, amapharamitha e-rotor ekuqaleni kanye nokusebenza kufanele abalwe ngokwehlukana.
Ukusabela kokuvuza kwe-rotor kwe-groove ejulileinjini engavumelani, ngenxa yokuma komsele ojulile we-rotor, incishiswa umphumela wesikhumba, kodwa ngemva kokunciphisa, ukusabela kokuvuza kwe-rotor kusekukhulu kunokwe-rotor evamile yekheji lesikwele. Ngakho-ke, amandla kanye ne-torque ephezulu yama-motor e-deep groove kuphansi kancane kunalawo ama-motor avamile ekheji lesikwele.
