Isigaba sesithathu se-asynchronous motor rotor core is slotted ukuze ifake i-rotor winding okanye i-aluminium ephosiweyo (okanye i-alloy alloy aluminium, iphose ubhedu); i-stator idla ngokuba yi-slot, kwaye umsebenzi wayo kwakhona ukushumeka ukujika kwe-stator.Kwiimeko ezininzi, i-rotor chute isetyenziswa, kuba umsebenzi wokufaka uya kuba nzima ngakumbi emva kokuba i-stator ine-chute.Yintoni injongo yokusebenzisa i-chute?
Kukho i-harmonics yee-frequencies ezahlukeneyo ngaphakathi kwi-motor. Ngenxa yokuba i-stator ithatha i-windings esasaziweyo yomgama omfutshane, i-amplitude ye-harmonic magnetic potential of other frequencies ngaphandle kwe-harmonics yezinyo iyancipha kakhulu.Ekubeni i-coefficient yokujija izinyo ilingana ne-coefficient esisiseko yokujija kwamaza, amandla emagnetic e-harmonic yezinyo ayichaphazeleki.Ngenxa yokuba i-stator kunye ne-rotor yenqanaba lesithathu le-asynchronous motor is slotted, ukuxhathisa kwamagnetic kuyo yonke i-gap circumference ayilingani, kwaye i-torque ye-electromagnetic kunye ne-electromotive force force iyaguquguquka ngokufanelekileyo xa i-motor isebenza.
Emva kokuba i-rotor ityibilikisiwe, i-torque ye-electromagnetic eyenziwe kunye ne-electromotive force ifana nexabiso eliqhelekileyo le-rotor bar efanayo esasazwe ngokulinganayo kwisangqa, esinokuwenza buthathaka ngokufanelekileyo amandla ombane we-harmonic oveliswa yi-harmonic magnetic field yamazinyo, ngaloo ndlela. ukwenza buthathaka ezi torque eyongezelelweyo ebangelwa amasimi emagnetic magnetic kunciphisa ukungcangcazela kwe-electromagnetic kunye nengxolo.Nangona i-rotor skewed slot iya kunciphisa amandla amaza e-electromotive asisiseko abangelwa yirotor, idigri ye-skew slot ekhethiweyo ngokubanzi incinci kune-pole pitch, ngoko ke ayinampembelelo encinci ekusebenzeni okusisiseko kwemoto. Ke ngoko, iirotor ze-aluminium ezincinci kunye nobungakanani obuphakathi iimotor asynchronous Rotor chutes zisetyenziswa ngokuqhelekileyo.
I-rotor blanks ihlanjululwe ngendlela eqhelekileyo, kwaye i-rotor core ifakwe kwi-dummy shaft kunye neqhosha le-oblique linear. I-oblique groove ye-rotor core nayo i-helical.
Okokuthi, ii-rotor blanks zibethelwa ngendlela eqhelekileyo, kwaye i-rotor core ifakwe kwi-shaft yobuxoki kunye ne-helical oblique slot.I-groove edibeneyo ye-rotor core i-helical.
Oko kukuthi, umatshini wokubetha ngesantya esiphezulu uxhotyiswe kunye ne-accessory ye-punching slot, ukwenzela ukuba i-rotor nganye yokubhoboza ibethe iphepha elinye, kwaye i-punching die ngokuzenzekelayo ihambisa umgama omncinci kwicala lokubetha. ithambeka.I-rotor blanks ehlatywe ngolu hlobo inokuxhotyiswa ngokuzikhethela kunye ne-rotor core kunye ne-dummy shaft eneqhosha elichanekileyo.Olu hlobo lwe-rotor core olutyekeleyo lunenzuzo ngokukodwa kwi-rotor bar yobhedu, kuba i-slot ethambekele kwi-rotor core yentsimbi ayikho i-helical, kodwa iqonde, ekulungele ukufakela imivalo yobhedu.Nangona kunjalo, umyalelo kunye nolwalathiso lwamaphepha okubetha abethelwe ngolu hlobo alukwazi ukuguqulwa, ngaphandle koko intsimbi yentsimbi elaminated ayikwazi ukuhambelana nomzekelo.
Abakho baninzi abavelisi abanoomatshini bokubhoboza abanesantya esiphezulu kunye nezixhobo ze-groove ezithambileyo, kwaye kunzima ukwenza izitshixo ze-spiral inclined. Abavelisi abaninzi basebenzisa izitshixo ezithe tyaba ukupakisha ii-rotor cores.I-rotor slot bar ayinakusetyenziswa xa i-rotor core ikhethiweyo kunye neqhosha elichanekileyo le-oblique.Ngenxa yokuba imilo groove is spiral ngeli xesha, kunyeI-groove bar ithe tye, akunakwenzeka ukusebenzisa i-groove bar yokucwangcisa imilo ye-spiral groove.Ukuba kufuneka kusetyenziswe imivalo etyhidiweyo, imilinganiselo yeebhari ezifakiweyo kufuneka ibe ncinane kakhulu kuneendawo zokubeka i-rotor.Ingasebenza kuphela njengentonga estyiweyo.Ngoko ke, xa ukhetha i-rotor core kunye neqhosha le-oblique, iqhosha le-oblique lidlala indima ye-skew kunye nokubeka.Ingxaki ejongene nayo xa usebenzisa isitshixo se-oblique somgca ukukhetha i-oblique groove rotor core kukuphazamiseka phakathi kwe-helical skew ye-punched keyway kunye ne-skew eqondileyo yesitshixo se-oblique.Oko kukuthi, ngaphandle kombindi we-rotor core, kufuneka kubekho ukuphazamiseka phakathi kweqhosha elitshisiweyo kunye neqhosha le-oblique.
