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 emagnetic azinyo achaphazeleki.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, i-aluminiyam encinci kunye nobungakanani obuphakathi iimotor asynchronous motors 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 i-core 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 etyhidiweyo.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.
