Ngokuthandwa kokunikezwa kwamandla okuguquguqukayo, inkinga yokuqala kwemoto ixazululwe kalula, kepha ngokunikezwa kwamandla ajwayelekile, ukuqala kwe-squirrel-cage rotor asynchronous motor kuhlale kuyinkinga. Kusukela ekuhlaziyweni kokusebenza kokuqala nokusebenza kwe-asynchronous motor, kungabonakala ukuthi ukuze ukwandise i-torque yokuqala futhi unciphise okwamanje lapho uqala, ukumelana ne-rotor kuyadingeka ukuba kukhulu; ngenkathi injini isebenza, ukuze kuncishiswe ukusetshenziswa kwethusi kwe-rotor futhi kuthuthukiswe ukusebenza kahle kwezimoto, ukumelana ne-rotor kuyadingeka ukuthi kube kuncane Abanye; lokhu ngokusobala kuwukuphikisana.

Ukuze injini ye-rotor yesilonda, njengoba ukumelana kungaxhunywa ochungechungeni ekuqaleni, bese kunqunywa ngesikhathi sokusebenza, le mfuneko ihlangene kahle. Kodwa-ke, ukwakheka kwesilonda se-asynchronous motor kuyinkimbinkimbi, izindleko ziphezulu, futhi ukugcinwa kungenasici, ngakho-ke ukusetshenziswa kwayo kunqunyelwe ngezinga elithile; Ama-resistors, ngenkathi esebenza ngamabomu ngama-resistors amancane. I-slot ejulile kanye nama-double squirrel cage rotor motors analokhu kusebenza kokuqala. Namuhla, uNksz. ubambe iqhaza ekukhulumeni nge-deep slot rotor motor.

I-deep slot asynchronous motor

Ukuze uqinise umphumela wesikhumba, ukwakheka kwe-groove ye-groove ejulile ye-asynchronous motor rotor kujulile futhi kuncane, futhi isilinganiso sokujula kwe-groove kuya kububanzi be-groove ku-10-12. Lapho i-current idlula ibha yerotor, ukuvuza kazibuthe okuguquguqukayo okunqamula phansi kwebha kungaphezu kwalokho okuphambana nengxenye yenotshi. Ngakho-ke, uma ibha ibhekwa njengehlukaniswe eziningana ezincane Uma ama-conductor exhunywe ngokufanayo, abaqhubi abancane abaseduze naphansi kwe-slot banokusabela okukhulu kokuvuza, futhi okuseduze ne-slot, kuncane ukusabela kokuvuza.

 

Uma uqala, ngenxa yokuthi imvamisa ye-rotor yamanje iphezulu futhi ukusabela kokuvuza kukhulu, ukusatshalaliswa kwamanje ku-conductor ngayinye encane kuzoncika ekuphenduleni kokuvuza, futhi okukhulu ukusabela kokuvuza, kuncane ukuvuza kwamanje. Ngale ndlela, ngaphansi kwesenzo samandla afanayo abangelwa ukugeleza kozibuthe okuyinhloko kwegebe lomoya, ukuminyana kwamanje kubha eseduze naphansi kwesikhala kuzoba kuncane kakhulu, futhi uma usondela esikhaleni, umfutho wamanje mkhulu kakhulu. ukuminyana.

Ngenxa yomphumela wesikhumba, ngemva kokuba iningi lamanje licindezelwe engxenyeni engenhla yebha yomhlahlandlela, indima yebha yomhlahlandlela ngaphansi kwe-groove incane kakhulu. Hlangana nezidingo zokumelana okukhulu lapho uqala. Lapho i-motor iqalwa futhi injini isebenza ngokujwayelekile, njengoba imvamisa yamanje ye-rotor iphansi kakhulu, ukusabela kokuvuza kwe-rotor winding kuncane kakhulu kunokumelana ne-rotor, ngakho-ke ukusatshalaliswa kwamanje kuma-conductor amancane okukhulunywe ngenhla kuzoba ngokuyinhloko. kunqunywa ukumelana.

 

Njengoba ukumelana kwe-conductor ngayinye encane kuyalingana, okwamanje ku-bar kuzosatshalaliswa ngokulinganayo, ngakho-ke umphumela wesikhumba uyanyamalala ngokuyisisekelo, futhi ukumelana kwe-rotor bar kuba kuncane, eduze nokumelana ne-DC. Kungabonakala ukuthi ukumelana kwe-rotor ekusebenzeni okujwayelekile kuzokwehla ngokuzenzakalelayo, ngaleyo ndlela kwanelise umphumela wokunciphisa ukusetshenziswa kwethusi nokuthuthukisa ukusebenza kahle.

Uyini umphumela wesikhumba?Umphumela wesikhumba ubizwa nangokuthi umphumela wesikhumba. Lapho i-alternating current idlula ku-conductor, i-current izogxila ebusweni bomqhubi nokugeleza. Lesi simo sibizwa ngokuthi umphumela wesikhumba. Lapho i-current noma i-voltage iqhuba ku-conductor enama-electron ama-frequency aphezulu, azoqoqana phezu kwe-conductor ephelele esikhundleni sokusatshalaliswa ngokulinganayo endaweni ehlukanisayo ye-conductor yonke.

Umphumela wesikhumba awuthinti kuphela ukumelana ne-rotor, kodwa futhi uthinta ukusabela kokuvuza kwe-rotor. Ukusuka endleleni ye-slot leakage flux, kungabonakala ukuthi i-current edlula ku-conductor encane ikhiqiza kuphela ukugeleza kokuvuza ukusuka ku-conductor encane kuya ku-notch, futhi akukhiqizi ukugeleza kokuvuza kusuka kumqhubi omncane kuya phansi. slot. Ngoba lokhu kwakamuva akuxhumene nalesi samanje. Ngale ndlela, ngobukhulu obufanayo bamanje, lapho ukusondela phansi kwe-slot, i-flux yokuvuza izokhiqizwa, futhi lapho kusondela ukuvulwa kwe-slot, ukugeleza okuncane kokuvuza kuzokwenziwa. Kungabonakala ukuthi lapho umphumela wesikhumba ucindezela i-current kubha ku-notch, i-slot ukuvuza okuguquguqukayo okukhiqizwe yimanje okufanayo kuyehla, ngakho ukusabela kokuvuza kwe-slot kuncipha. Ngakho-ke umphumela wesikhumba ukhulisa ukumelana ne-rotor futhi unciphisa ukusabela kokuvuza kwe-rotor.

Amandla omphumela wesikhumba ancike emvamisa ye-rotor yamanje kanye nobukhulu bomumo we-slot. Lapho i-frequency iphezulu, i-slot shape ijula, futhi umphumela wesikhumba ubaluleke kakhulu. I-rotor efanayo nama-frequencies ahlukene izoba nemiphumela ehlukene yomphumela wesikhumba, futhi ngenxa yalokho imingcele ye-rotor izophinde ihluke. Ngenxa yalokhu, ukumelana ne-rotor kanye nokusabela kokuvuza ngesikhathi sokusebenza okuvamile nokuqala kufanele kuhlukaniswe ngokuqinile futhi akukwazi ukudideka. Ngokwemvamisa efanayo, umphumela wesikhumba we-groove rotor ejulile unamandla kakhulu, kodwa umphumela wesikhumba nawo unethonya elithile esakhiweni esivamile se-squirrel cage rotor. Ngakho-ke, ngisho ne-squirrel-cage rotor enesakhiwo esivamile, imingcele ye-rotor ekuqaleni nokusebenza kufanele ibalwe ngokwehlukana.

Ukusabela kokuvuza kwe-rotor ye-slot ejulile ye-asynchronous motor, ngoba i-rotor slot shape ijulile kakhulu, nakuba iyancipha ngenxa yethonya lomphumela wesikhumba, isenkulu kune-squirrel cage rotor ukusabela kokuvuza ngemva kokunciphisa. Ngakho-ke, isici samandla kanye ne-torque enkulu ye-deep slot motor iphansi kancane kunaleyo ye-squirrel cage motor evamile.
