Imivalo ebhityileyo okanye imivalo eyaphukileyo ngokuqhelekileyo isetyenziswa amagama aneempazamo kwiinjini ze-aluminiyam rotor. Zombini imivalo emincinci kunye nemivalo ephukileyo ibhekiselele kwi-rotor bars. Ngokwethiyori, emva kokuba i-rotor's punching slot shape, ubude bentsimbi, kunye ne-slope ye-slope inqunywe, imivalo ye-rotor ichazwe ngendlela eqhelekileyo. Nangona kunjalo, kweyona nkqubo yokuvelisa, izizathu ezahlukeneyo zihlala zibangela ukuba imivalo ye-rotor yokugqibela ijikwe kwaye ikhubazeke, kunye nemingxuma eyanciphayo ibonakala ngaphakathi kwemivalo. Kwiimeko ezinzima, imivalo inokuphuka.
Ekubeni i-rotor core yenziwe nge-rotor punchings, i-positioning circumferential positioning yenziwa ngeentonga ezidibeneyo ezihambelana ne-rotor punchings ngexesha lenkqubo ye-lamination. Emva kokugqitywa, iintonga ezifakwe kwi-slot zithathwa kwaye ziphosa i-aluminium kunye ne-mold. Ukuba i-rods slotted kunye neendawo zokubeka zikhululekile kakhulu, i-punchings iya kuba needigri ezahlukeneyo zokufuduka okujikelezayo ngexesha lenkqubo ye-lamination, eya kuthi ekugqibeleni ikhokelele kwi-wavy surfaces kwi-rotor bar, i-sawtooth phenomena kwi-rotor core slots, kunye nemivalo ephukileyo. Ukongeza, inkqubo yokuphosa i-aluminium ikwayinkqubo yokuqinisa i-aluminium engamanzi engena kwiindawo zokubeka i-rotor. Ukuba i-aluminium yolwelo ixutywe negesi ngexesha lenkqubo yokutofa kwaye ayikwazi ukukhutshwa kakuhle, ii-pores ziya kwenziwa kwindawo ethile yemivalo. Ukuba iipores zikhulu kakhulu, ziya kubangela ukuphuka kwe-rotor bar.
Ukwandiswa kolwazi - i-groove enzulu kunye ne-double cageiinjini ezilinganayo
Ukususela kuhlalutyo lokuqala kwe-cage asynchronous motor, kunokubonwa ukuba xa uqala ngokuthe ngqo, ukuqala ngoku kukhulu kakhulu; xa uqala nge-voltage encitshisiweyo, nangona i-current current iyancipha, i-torque yokuqala nayo iyancitshiswa. Ngokutsho kweempawu ezenziwe ngomatshini wokumelana nochungechunge lwe-asynchronous motor rotor, kunokubonwa ukuba ukwandisa ukuxhathisa kwe-rotor ngaphakathi koluhlu oluthile kunokunyusa i-torque yokuqala, kunye nokwandisa ukuxhathisa kwe-rotor kuya kunciphisa ukuqala ngoku. Ngoko ke, ukuxhathisa okukhulu kwe-rotor kunokuphucula ukusebenza kokuqala.
Nangona kunjalo, xa i-motor isebenza ngokuqhelekileyo, kunethemba lokuba ukuchasana kwe-rotor kuncinci, kunokunciphisa ukulahleka kobhedu kwe-rotor kunye nokuphucula ukusebenza kakuhle kwemoto. Ngaba i-cage asynchronous motor ingaba nokumelana ne-rotor enkulu xa iqala, kwaye ukuxhathisa kwe-rotor ngokuzenzekelayo kuncipha ngexesha lokusebenza okuqhelekileyo? I-slot enzulu kunye ne-double cage asynchronous motors inokufezekisa le njongo.
Indawo enzului-asynchronous motor
I-rotor slot ye-slot enzulu ye-asynchronous motor inzulu kwaye imxinwa, kwaye umlinganiselo we-slot ubunzulu ukuya kububanzi be-slot idla ngokuba yi-10 ukuya kwi-12 okanye ngaphezulu. Xa ngoku uqukuqela kwi-rotor imivalo, ukuvuza okuvuzayo okudityaniswe namazantsi eentsimbi kukhulu kunokokuvuza okudityaniswe nokuvuleka kweslot. Ke ngoko, ukuba imivalo ithathwa njengenani labaqhubi abancinci abahlulwe ecaleni kobude besithuba esiqhagamshelwe ngokunxuseneyo, iicondakta ezincinci ezikufutshane nezantsi kwindawo yokubeka zinobuxhakaxhaka bokuvuza okukhulu, kwaye abaqhubi abancinci abakufutshane nendawo yokuvula banendawo encinci. ukusabela kokuvuza.
Xa i-motor iqala, ngenxa ye-frequency ephezulu ye-rotor yangoku, ukuphendulwa kokuvuza kwee-rotor bars kukhulu, ngoko ke ukuhanjiswa kwangoku kwi-conductor nganye encinci kuya kugqitywa ngokukodwa ngokuphendula ukuvuza. Okukhona ukusabela kokuvuza okukhulu, kokukhona kuncinci okwangoku. Ngale ndlela, phantsi kwamandla afanayo e-electromotive abangelwa yi-flux engundoqo yamagnetic ye-gap yomoya, ukuxinana kwangoku kufuphi nomzantsi we-slot kwi-conductor kuya kuba kuncinci kakhulu, kwaye ngokusondeleyo kwi-slot, iya kuba nkulu. Le nto ibizwa ngokuba yimpembelelo yesikhumba yangoku. Ilingana nekhoyo ngoku icinezelwe kwi-slot, ngoko ikwabizwa ngokuba yimpembelelo yokukhama. Umphumo wempembelelo yesikhumba ulingana nokunciphisa ukuphakama kunye ne-cross-section ye-conductor bar, ukwandisa ukuchasana kwe-rotor, kwaye ngaloo ndlela ukuhlangabezana neemfuno zokuqala.
Xa isiqalo sigqityiwe kwaye i-motor isebenza ngokuqhelekileyo, i-frequency ye-rotor yangoku iphantsi kakhulu, ngokubanzi i-1 ukuya kwi-3 Hz, kwaye ukusabela kokuvuza kwee-rotor bars kuncinci kakhulu kunokumelana ne-rotor. Ngoko ke, ukuhanjiswa kwangoku kubaqhubi abancinci abakhankanywe ngasentla kuya kugqitywa ngokukodwa ngokuchasana. Ekubeni ukuchasana kwe-conductor nganye encinci kuyalingana, okwangoku kwimivalo iya kusasazwa ngokulinganayo, kwaye umphumo wesikhumba uyanyamalala, ngoko ke ukuchasana kwe-rotor bar kubuyela kwi-DC yayo. Kuya kubonakala ukuba ngexesha lokusebenza okuqhelekileyo, ukuxhathisa kwe-rotor ye-slot enzulu ye-asynchronous motor inokwehla ngokuzenzekelayo, ngaloo ndlela ihlangabezana neemfuno zokunciphisa ilahleko yobhedu ye-rotor kunye nokuphucula ukusebenza kakuhle kwemoto.
Injini yeasynchronous ephindwe kabini
Kukho iikheji ezimbini kwi-rotor ye-double-cage asynchronous motor, oko kukuthi i-cage ephezulu kunye ne-cage ephantsi. Imivalo ye-cage ephezulu inommandla omncinci we-cross-sectional kwaye yenziwe ngezinto ezinokumelana okuphezulu njengobhedu okanye i-aluminium yobhedu, kwaye inokumelana okukhulu; imivalo ye-cage ephantsi inommandla omkhulu we-cross-sectional kwaye yenziwe ngobhedu kunye ne-resistiveivity ephantsi, kwaye inokumelana okuncinci. Iimotor ezine-cage ephindwe kabini zihlala zisebenzisa i-rotors ye-aluminium ephosiweyo; Kuyacaca ukuba ukuvuza kwekheji esezantsi kungaphezulu kakhulu kuneyekheji ephezulu, ngoko ke ukusabela kokuvuza kwekheji esezantsi nako kukhulu kunoko kwekheji ephezulu.
