Mabhawa matete kana mabhawa akatyoka anowanzo shandiswa mazwi ekukanganisa mune akakanda aluminium rotor motors. Ose mazariro matete uye akatyoka mbariro anoreva marotor bars. Nechepfungwa, kana rotor's punching slot shape, kureba kwesimbi, uye mutserendende wakatemerwa, marotor bars anotsanangurwa mune yakajairika chimiro. Zvisinei, mune chaiyo yekugadzira maitiro, zvikonzero zvakasiyana-siyana zvinowanzokonzera kuti mabheji ekupedzisira e rotor ave akamonyoroka uye akaremara, uye kunyange shrinkage maburi anooneka mukati membariro. Muzviitiko zvakakomba, mbariro dzinogona kuputsika.
Sezvo iyo rotor core yakagadzirwa ne rotor punchings, iyo circumferential positioning inoitwa neiyo slotted tsvimbo inoenderana neiyo rotor punching panguva yelamination process. Mushure mekupedzwa, matanda akaiswa anotorwa kunze uye anokandwa aluminium ne mold. Kana matanda akatsvetwa uye maslots akanyanya kusununguka, zvibhakera zvichange zvine madhigirii akasiyana ekutenderera kwekutenderera panguva yelamination process, iyo inozopedzisira yatungamira kune wavy pamusoro pemarotor bars, sawtooth phenomena pane rotor core slots, uye kunyange akatyoka mabara. Uye zvakare, iyo aluminium yekukanda maitiro zvakare ndiyo yekusimbisa maitiro emvura aluminium inopinda mumarotor slots. Kana iyo aruminiyamu yemvura yakasanganiswa negasi panguva yejekiseni uye isingakwanise kuburitswa zvakanaka, pores inoumbwa mune imwe chikamu chemabhawa. Kana ma pores akanyanya kukura, zvinokonzeresa kuparara kwerotor bar.
Kuwedzera ruzivo - yakadzika groove uye kaviri cageasynchronous motors
Kubva pakuongorora kwekutanga kwecage asynchronous motor, zvinogona kuonekwa kuti kana uchitanga zvakananga, kutanga ikozvino kwakakura; kana uchitanga neyakaderedzwa voltage, kunyangwe iyo yekutanga ikozvino yakaderedzwa, iyo yekutanga torque inoderedzwa zvakare. Zvinoenderana neyakagadzirwa mechanicha maitiro eakateedzana kushorwa kweasynchronous mota rotor, zvinogona kuoneka kuti kuwedzera rotor kuramba mukati meimwe mhando kunogona kuwedzera torque yekutanga, uye kuwedzera kupikisa kwerotor kuchaderedzawo kutanga ikozvino. Naizvozvo, yakakura rotor kuramba inogona kuvandudza kutanga kuita.
Zvisinei, kana motokari ichimhanya zvakajairika, zvinotarisirwa kuti kupikisa kwe rotor kuduku, izvo zvinogona kuderedza kurasikirwa kwemhangura ye rotor uye kuvandudza kushanda kwemotokari. Ko iyo cage asynchronous mota ingave neyakakura rotor kuramba kana ichitanga, uye iyo rotor kuramba inongodzikira panguva yekushanda? Yakadzika slot uye kaviri cage asynchronous motors inogona kuzadzisa ichi chinangwa.
Deep slotasynchronous mota
Iyo rotor slot yeyakadzika slot asynchronous mota yakadzika uye yakamanikana, uye reshiyo yekudzika kweslot kusvika kuhupamhi hweslot inowanzosvika gumi kusvika gumi nemaviri kana kupfuura. Kana yazvino ichiyerera nepakati pemarotor baa, iyo yekuvuza inoyerera yakabatana nepasi pemabhawa yakakura kupfuura iyo yekuvuza flux yakabatana nekuvhura slot. Naizvozvo, kana mabhawa achionekwa seakawanda maconductor madiki akapatsanurwa pamwe nehupamhi hwe slot akabatana mukufanana, maconductor madiki ari padyo nepasi peiyo slot ane hombe yekudonha reactance, uye maconductor madiki ari padhuze nekuvhura slot ane diki. leakage reactance.
Kana iyo mota inotanga, nekuda kweiyo yakakwira frequency ye rotor ikozvino, iyo leakage reactance yerotor bars yakakura, saka kugoverwa kwezvino mune imwe neimwe conductor diki ichave yakanyanya kutsanangurwa nekudonha reactance. Iyo yakakura iyo leakage reactance, idiki ikozvino. Nenzira iyi, pasi pesimba rimwechete re electromotive rinokonzerwa neiyo huru yemagineti yemhepo gap, ikozvino density pedyo nechepasi pechigadziko mu conductor ichava chiduku zvikuru, uye pedyo ne slot, iyo ichava yakakura. Ichi chiitiko chinodaidzwa kuti ganda mhedzisiro yezvino. Iyo yakaenzana neyezvino iri kusvinwa kune slot, saka inonziwo kusvina maitiro. Mhedzisiro yeganda mhedzisiro yakaenzana nekudzikisa kureba uye kuyambuka-chikamu che conductor bar, kuwedzera rotor kuramba, uye nekudaro kusangana nekutanga zvinodiwa.
Kana iyo yekutanga yapera uye mota ichimhanya zvakajairika, iyo rotor yazvino frequency yakadzikira, kazhinji 1 kusvika 3 Hz, uye kudonhedza kwekuita kwemarotor bars kudiki zvakanyanya pane kuramba kwerotor. Nokudaro, kugoverwa kwezvino mune zvataurwa pamusoro apa zvidhori zviduku zvichange zvichinyanya kugadziriswa nekupikisa. Sezvo kushorwa kwemudiki wega wega conductor kwakaenzana, ikozvino mumabhawa ichagoverwa zvakaenzana, uye ganda mhedzisiro inonyangarika, saka iyo rotor bar kuramba inodzokera kune yayo DC kuramba. Zvinogona kuoneka kuti panguva yekushanda kwakajairika, iyo rotor kuramba yeyakadzika slot asynchronous mota inogona kudzika yega, nekudaro ichisangana nezvinodiwa zvekudzikisa rotor mhangura kurasikirwa nekuvandudza mota.
Kaviri-cage asynchronous mota
Kune makeji maviri pane rotor yekaviri-cage asynchronous mota, iyo yekumusoro keji uye yakaderera keji. Mabheji epamusoro ane nzvimbo diki yemuchinjikwa uye anogadzirwa nezvinhu zvine resitiri yepamusoro yakadai sendarira kana aluminium bronze, uye ane kurwisana kukuru; mabheji ezasi ane nzvimbo yakakura yemuchinjikwa uye yakagadzirwa nemhangura ine resistivity yakaderera, uye ine kushoma kuduku. Kaviri-cage motors zvakare inowanzoshandisa cast cast aluminium rotors; zviri pachena kuti kubuda kwemvura kwekeji yepasi kwakanyanya kudarika iyo yekumusoro kwekeji, saka iyo inodonha reactance yeyakadzika keji zvakare yakakura kupfuura iyo yekumusoro keji.
