I-asynchronous motor rotor core enezigaba ezintathu ifakwe ukushumeka i-rotor winding noma i-cast aluminium (noma i-cast alloy aluminium, ithusi eliphonswe); i-stator ivamise ukugoba, futhi umsebenzi wayo uwukushumeka ukujika kwe-stator.Ezimweni eziningi, i-rotor chute isetshenziswa, ngoba umsebenzi wokufaka uzoba nzima kakhulu ngemva kokuba i-stator ine-chute.Iyini inhloso yokusebenzisa i-chute?
Kukhona ama-harmonics amaza ahlukahlukene ngaphakathi kwe-motor. Ngenxa yokuthi i-stator ithatha ama-windings asabalele ebangeni elifushane, i-amplitude yamandla kazibuthe we-harmonic yamanye amafrikhwensi ngaphandle kwe-harmonics yezinyo iba buthaka kakhulu.Njengoba i-coefficient enyakazayo ye-harmonic yezinyo ilingana ne-coefficient yamagagasi ayisisekelo, amandla kazibuthe we-tooth harmonic awathinteki neze.Ngenxa yokuthi i-stator ne-rotor ye-asynchronous motor yezigaba ezintathu ifakwe, ukumelana kazibuthe kwayo yonke igebe yomjikelezo womoya ayilingani, kanye ne-torque kagesi kanye namandla e-electromotive eyenziwe ashintshashintsha ngokufanele lapho injini isebenza.
Ngemuva kokuthi i-rotor isitshekile, i-torque ka-electromagnetic eyakhiwe namandla e-electromotive eyengayo afana nenani eliphakathi le-rotor bar efanayo esatshalaliswa ngokulinganayo kuyindilinga, engenza buthaka ngokuphumelelayo amandla e-harmonic electromotive akhiqizwa yi-harmonic magnetic field yamazinyo, ngaleyo ndlela. ukwenza buthaka le torque eyengeziwe ebangelwa izizinda kazibuthe ezivumelanayo kunciphisa ukudlidliza nomsindo kagesi.Nakuba i-rotor skewed slot izophinde inciphise amandla ayisisekelo e-electromotive wave abangelwa i-rotor, i-skew slot degree evame ukukhethwa incane kakhulu kune-pole pitch, ngakho ayinamthelela omncane ekusebenzeni okuyisisekelo kwenjini. Ngakho-ke, ama-rotor aluminium rotor amancane naphakathi nendawo asetshenziswa kakhulu ama-Rotor chutes.
Izikhala ze-rotor zishaywa ngendlela evamile, futhi i-rotor core ihlanganiswe ne-dummy shaft enokhiye oblique oqondile. I-oblique groove ye-rotor core nayo i-helical.
Okusho ukuthi, izikhala ze-rotor zishaywa ngendlela evamile, futhi i-rotor core ihlanganiswe ne-shaft yamanga ene-helical oblique slot.I-groove ethambekele ye-rotor core i-helical.
Okusho ukuthi, umshini wokubhoboza ngesivinini esiphezulu ufakwe isesekeli se-punching slot, ukuze i-rotor ngayinye yokubhoboza ibhoboze ishidi elilodwa, futhi ukufa kokubhoboza ngokuzenzakalelayo kuhamba ibanga elincane eduze kokuqondisa kwesibhakela. umthambeka.Izikhala ze-rotor ezikhohliwe ngale ndlela zingahlonyiswa ngokuzikhethela nge-rotor core ene-dummy shaft enokhiye oqondile.Lolu hlobo lokuthambekela kwe-slot rotor core luzuzisa kakhulu i-copper bar rotor, ngoba i-slot ethambekele ye-rotor iron core ayiyona i-helical, kodwa iqondile, ekulungele ukufakwa kwemigoqo yethusi.Kodwa-ke, ukuhleleka nokuqondiswa kwamashidi okubhoboza ashaywa ngale ndlela akukwazi ukuhlehliswa, ngaphandle kwalokho umgogodla wensimbi elaminethiwe awukwazi ukuhambisana nephethini.
Abekho abakhiqizi abaningi abanemishini yokubhoboza enesivinini esikhulu enezinsimbi zokubhoboza nezithambekile ze-groove, futhi kunzima ukwenza okhiye abathambekele ku-spiral. Abakhiqizi abaningi basebenzisa okhiye abathambekile abayisicaba ukuze babeke ama-groove rotor cores.I-rotor slot bar ayikwazi ukusetshenziswa lapho i-rotor core ikhethiwe ngokhiye oqondile we-oblique.Ngoba umumo groove is Kuvunguza ngalesi sikhathi, futhiI-groove bar iqondile, akunakwenzeka ukusebenzisa ibha ye-groove eqondile ukuze uhlele ukuma kwe-spiral groove.Uma kuzosetshenziswa amabha afakiwe, izilinganiso zamabha afakiwe kufanele zibe zincane kakhulu kunezikhala ze-rotor.Ingasebenza kuphela njengenduku ecijile.Ngakho-ke, lapho ukhetha i-rotor core nge-oblique key, ukhiye we-oblique udlala kokubili indima ye-skew nokubeka.Inkinga okuhlangatshezwane nayo lapho kusetshenziswa ukhiye we-oblique olayini ukuze ukhethe i-oblique groove rotor core ukugxambukela phakathi kwe-helical skew yokhiye obhontshiwe kanye ne-skew eqondile yokhiye we-oblique.Okusho ukuthi, ngaphandle kwemaphakathi ne-rotor core, kufanele kube nokuphazanyiswa phakathi kokhiye obhontshiwe kanye nokhiye oblique.
