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 yokuqina kwe-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. Ngoko ke, ukuba imivalo ithathwa njengenani labaqhubi abancinci abahlulwe kunye nobude be-slot edibeneyo ngokuhambelanayo, ii-conductors ezincinci ezikufutshane nezantsi kwendawo yokubeka zine-reactance yokuvuza enkulu, kunye nabaqhubi abancinci abasondeleyo kwi-slot yokuvula bane-reactance encinci yokuvuza.
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 nge-copper ene-resistiveivity ephantsi, kwaye inokumelana okuncinci. Iimotor ezine-cage 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.
