Ngokuthandwa kombane oguquguqukayo oguquguqukayo, ingxaki yokuqalisa imotor isonjululwe ngokulula, kodwa kunikezelo lwamandla oluqhelekileyo, ukuqala kwe-squirrel-cage rotor asynchronous motor kuhlala kuyingxaki. Ukususela kuhlalutyo lokuqala kunye nokusebenza kwe-asynchronous motor, kunokubonwa ukuba ukwenzela ukwandisa i-torque yokuqala kunye nokunciphisa okwangoku xa uqala, ukuchasana kwe-rotor kuyadingeka ukuba kukhulu; ngelixa i-motor isebenza, ukwenzela ukunciphisa ukusetyenziswa kobhedu kwe-rotor kunye nokuphucula ukusebenza kwemoto, ukuxhathisa kwe-rotor kuyadingeka ukuba kuncinci Abanye; oku kukuphikisana ngokucacileyo.

Kwimoto ye-rotor yesilonda, ekubeni ukuchasana kunokudibaniswa kuchungechunge ekuqaleni, kwaye emva koko kunqunyulwa ngexesha lokusebenza, le mfuneko idibene kakuhle. Nangona kunjalo, isakhiwo sesilonda se-asynchronous motor siyinkimbinkimbi, iindleko ziphezulu, kwaye ukugcinwa kungenakulungeleka, ngoko ke ukusetyenziswa kwayo kunqunyelwe kwinqanaba elithile; I-Resistors, ngelixa isebenza ngenjongo kunye ne-resistors ezincinci. I-slot enzulu kunye ne-double squirrel cage rotor motors zinale ntsebenzo yokuqala. Namhlanje, uNkszn uthathe inxaxheba ekuthetheni malunga ne-rotor ye-rotor motor.

Deep slot asynchronous motor

Ukuze uqinise impembelelo yesikhumba, i-groove shape ye-groove enzulu ye-asynchronous motor rotor inzulu kwaye incinci, kwaye umlinganiselo wobunzulu be-groove ukuya kububanzi be-groove kuluhlu lwe-10-12. Xa i-current idlula kwi-rotor bar, ukuvuza kwamagnetic flux intersecting kunye ne-bottom yebar kungaphezulu kakhulu kunokudibanisa kunye nengxenye yenotshi. Ngoko ke, ukuba ibha ithathwa ukuba yahlulwe ngamancinci amancinci Ukuba abaqhubi badityaniswe ngokuhambelanayo, abaqhubi abancinci abasondeleyo kumazantsi e-slot banokusabela okukhulu kokuvuza, kwaye ngokusondeleyo kwi-slot, i-reactance encinci yokuvuza.

 

Xa uqala, ngenxa yokuba i-frequency ye-rotor yangoku iphezulu kwaye i-reactance yokuvuza inkulu, ukuhanjiswa kwangoku kwi-conductor nganye encinci kuya kuxhomekeka kwi-reactance yokuvuza, kunye nokukhulu ukusabela kokuvuza, kuncinci ukuvuza kwangoku. Ngale ndlela, phantsi kwesenzo sesakhono esifanayo esibangelwa yi-flux engundoqo yemagnethi ye-gap yomoya, ukuxinana kwangoku kwi-bar kufuphi nomzantsi we-slot kuya kuba ncinane kakhulu, kwaye ngokusondeleyo kwi-slot, inkulu yangoku. ukuxinana.

Ngenxa yempembelelo yesikhumba, emva kokuba ininzi yangoku igxininiswe kwindawo ephezulu yebar yesikhokelo, indima yebar yesikhokelo ephantsi kwe-groove incinci kakhulu. Ukuhlangabezana neemfuno zokuxhathisa okukhulu xa uqala. Xa i-motor iqaliswa kwaye i-motor isebenza ngokuqhelekileyo, ekubeni i-frequency ye-rotor yangoku iphantsi kakhulu, ukusabela kokuvuza kwe-rotor winding incinci kakhulu kunokumelana ne-rotor, ngoko ke ukusasazwa kombane kubaqhubi abancinci abakhankanywe ngasentla kuya kuba igqitywe kukuchasa.

 

Ekubeni ukuchasana kwe-conductor nganye encinci kuyalingana, i-current in bar iya kusasazwa ngokulinganayo, ngoko ke umphumo wesikhumba uyanyamalala, kwaye ukuchasana kwe-rotor bar kuba kuncinci, kufutshane nokuxhatshazwa kwe-DC. Ingabonwa ukuba ukuchasana kwe-rotor ekusebenzeni okuqhelekileyo kuya kuncipha ngokuzenzekelayo, ngaloo ndlela kuyanelisa umphumo wokunciphisa ukusetyenziswa kobhedu kunye nokuphucula ukusebenza kakuhle.

Yintoni umphumo wolusu?Umphumo wesikhumba ubizwa ngokuba yimpembelelo yesikhumba. Xa i-alternating current idlula kwi-conductor, i-current iya kugxininisa kwindawo yomqhubi kunye nokuhamba. Le nto ibizwa ngokuba yimpembelelo yesikhumba. Xa i-voltage yangoku okanye i-voltage iqhuba kwi-conductor enee-electron ezihamba rhoqo, ziya kubuthana kumphezulu we-conductor iyonke endaweni yokuba zisasazwe ngokulinganayo kwindawo enqamlezileyo yomqhubi wonke.

Umphumo wesikhumba awuchaphazeli kuphela ukuchasana kwe-rotor, kodwa uchaphazela ukusabela kokuvuza kwe-rotor. Ukusuka kwindlela ye-slot yokuvuza, kunokubonwa ukuba i-current edlula kwi-conductor encinci ivelisa kuphela i-flux yokuvuza ukusuka kwi-conductor encinci ukuya kwi-notch, kwaye ayivelisi i-flux yokuvuza ukusuka kwi-conductor encinci ukuya ezantsi kwe-conductor encinci. slot. Ngenxa yokuba le yokugqibela ayidityaniswanga nalo ngoku. Ngale ndlela, ngenxa yobukhulu obufanayo bangoku, ngokusondeleyo ukuya ngaphantsi kwe-slot, i-flux yokuvuza iya kuveliswa, kwaye ngokusondeleyo kwi-slot yokuvula, i-flux yokuvuza encinci iya kuveliswa. Ingabonwa ukuba xa isiphumo ulusu incudisa yangoku kwibar ukuya notch, slot ukuvuza flux kazibuthe eveliswa ngokwangoku efanayo kuncipha, ngoko slot ukuvuza reactance kuncipha. Ngoko umphumo wesikhumba unyusa ukuxhathisa kwe-rotor kwaye unciphisa ukusabela kokuvuza kwe-rotor.

Amandla omphumo wesikhumba kuxhomekeke kwi-frequency ye-rotor yangoku kunye nobukhulu be-slot shape. Okukhona iphezulu i-frequency, inzulu i-slot shape, kwaye ibaluleke ngakumbi impembelelo yesikhumba. I-rotor efanayo kunye nee-frequencies ezahlukeneyo ziya kuba nemiphumo eyahlukileyo yempembelelo yesikhumba, kwaye ngenxa yoko iiparamitha ze-rotor ziya kuba zihluke. Ngenxa yoko, ukuchasana kwe-rotor kunye nokuphendula kokuvuza ngexesha lokusebenza okuqhelekileyo kunye nokuqala kufuneka kuhluke ngokuthe ngqo kwaye akunakudideka. Kwi-frequency efanayo, impembelelo yesikhumba ye-rotor ye-groove enzulu yomelele kakhulu, kodwa impembelelo yesikhumba nayo inomlinganiselo othile wempembelelo kwisakhiwo esiqhelekileyo se-squirrel cage rotor. Ngoko ke, nakwi-squirrel-cage rotor enesakhiwo esiqhelekileyo, iiparamitha ze-rotor ekuqaleni kunye nokusebenza kufuneka zibalwe ngokwahlukileyo.

I-rotor leak reactance ye-deep slot asynchronous motor, ngenxa yokuba i-rotor slot shape inzulu kakhulu, nangona iyancipha ngenxa yempembelelo yesikhumba, isenkulu kune-squirrel cage rotor yokuvuza ukusabela emva kokunciphisa. Ke ngoko, amandla ombane kunye ne-torque ephezulu ye-slot motor enzulu ingaphantsi kancinci kuneemoto eziqhelekileyo ze-squirrel cage.
