Covlub rotorntawm DC lub cev muaj zog muaj ib qho laminated ntawm hluav taws xob hlau. Thaum lub rotor tig nyob rau hauv lub cev muaj zog magnetic teb, nws generates ib tug voltage nyob rau hauv lub kauj, uas generates eddy tam sim no, uas yog ib yam ntawm cov hlau nplaum poob, thiab eddy tam sim no poob ua rau lub hwj chim poob. Ntau yam cuam tshuam rau cov nyhuv eddy tam sim no ntawm lub zog poob, xws li electromagnetic teb, lub thickness ntawm cov khoom sib nqus, thiab qhov ntom ntawm cov hlau nplaum flux. Qhov kev tiv thaiv ntawm cov khoom siv rau tam sim no cuam tshuam rau txoj kev eddy tam sim no tsim, piv txwv li, thaum cov khoom tuab heev, qhov chaw hla ntu nce, ua rau eddy tam sim no poob. Cov ntaub ntawv nyias nyias yuav tsum tau ua kom txo qis qhov chaw hla ntu. Txhawm rau ua kom cov khoom nyias nyias, cov tuam txhab siv ntau daim ntawv nyias hu ua laminations los tsim cov tub ntxhais armature, thiab tsis zoo li cov ntawv tuab, cov ntawv nyias nyias ua kom muaj zog dua, uas ua rau tsis tshua muaj eddy tam sim no.
Kev xaiv cov khoom siv rau lub cev muaj zog laminations yog ib qho tseem ceeb tshaj plaws hauv cov txheej txheem tsim lub cev muaj zog, thiab vim tias lawv muaj ntau yam, qee qhov kev xaiv nrov tshaj plaws yog txias-dov lub cev muaj zog laminated steel thiab silicon steel. Cov ntsiab lus silicon siab (2-5.5 wt% silicon) thiab nyias phaj (0.2-0.65 hli) steels yog cov khoom sib nqus mos rau lub cev muaj zog stators thiab rotors. Qhov sib ntxiv ntawm silicon rau hlau ua rau qis coercivity thiab siab dua resistivity, thiab txo cov phaj nyias thickness ua rau qis eddy tam sim no poob.
Cold dov laminated steel yog ib qho ntawm cov khoom siv qis tshaj plaws hauv kev tsim khoom loj thiab yog ib qho ntawm cov khoom siv nrov tshaj plaws. Cov khoom siv tau yooj yim rau stamping thiab ua kom tsis tshua muaj hnav ntawm cov cuab yeej stamping dua li lwm cov ntaub ntawv. Lub cev muaj zog manufacturers anneal lub cev muaj zog laminated hlau nrog ib tug oxide zaj duab xis uas ua rau kom interlayer tsis kam, ua rau nws piv rau tsawg-silicon steels. Qhov sib txawv ntawm lub cev muaj zog laminated steel thiab txias-dov hlau yog nyob rau hauv cov hlau muaj pes tsawg leeg thiab kev txhim kho kev ua haujlwm (xws li annealing).
Silicon steel, tseem hu ua hluav taws xob hlau, yog cov pa roj carbon tsawg nrog ib qho me me ntawm silicon ntxiv los txo qhov poob tam sim no hauv cov tub ntxhais. Silicon tiv thaiv cov stator thiab transformer cores thiab txo cov hysteresis ntawm cov khoom, lub sij hawm ntawm thawj tiam ntawm lub magnetic teb thiab nws tag nrho tiam. Thaum txias dov thiab zoo oriented, cov khoom yog npaj rau lamination daim ntaub ntawv. Feem ntau, silicon steel laminates yog insulated ntawm ob sab thiab stacked nyob rau sab saum toj ntawm txhua lwm yam kom txo tau eddy tam sim no, thiab ntxiv ntawm silicon rau cov alloy muaj ib tug tseem ceeb cuam tshuam rau lub neej ntawm stamping cov cuab yeej thiab tuag.
Silicon steel muaj nyob rau hauv ntau yam thicknesses thiab qib, nrog rau qhov zoo tshaj plaws hom nyob ntawm seb cov hlau tso cai poob nyob rau hauv watts ib kilogram. Txhua qib thiab tuab cuam tshuam rau qhov chaw rwb thaiv tsev ntawm cov hlau, lub neej ntawm cov cuab yeej stamping, thiab lub neej ntawm cov tuag. Zoo li txias-dov lub cev muaj zog laminated steel, annealing pab ntxiv dag zog rau silicon steel, thiab cov txheej txheem tom qab stamping annealing tshem tawm cov pa roj carbon ntau, yog li txo cov kev ntxhov siab. Nyob ntawm seb hom silicon steel siv, kev kho mob ntxiv ntawm cov khoom yuav tsum tau ua kom txo qis kev ntxhov siab ntxiv.
Cov txheej txheem txias-kuav los tiag steel tsim tau ntxiv qhov zoo rau cov khoom siv raw. Cold-dov manufacturing yog ua nyob rau hauv los yog me ntsis saum toj no chav tsev kub, ua rau cov nplej ntawm steel seem elongated nyob rau hauv lub dov kev taw qhia. Kev kub siab siv rau cov khoom siv thaum lub sij hawm tsim cov txheej txheem kho cov txheej txheem rigidity ntawm cov hlau txias, ua rau lub ntsej muag du thiab ntau meej thiab zoo ib yam. Cov txheej txheem txias dov kuj ua rau lub npe hu ua "strain hardening", uas tuaj yeem ua rau cov tawv tawv nce mus txog 20% piv rau cov hlau tsis muaj dov hauv qib hu ua tag nrho cov tawv tawv, ib nrab hardening, lub quarter nyuaj thiab nto dov. Rolling yog muaj nyob rau hauv ntau yam duab, xws li puag ncig, square thiab tiaj tus, thiab nyob rau hauv ib tug ntau yam ntawm cov qib kom haum ib tug ntau yam ntawm lub zog, siv thiab ductility yuav tsum tau, thiab nws cov nqi qis tseem ua rau nws lub caj qaum ntawm tag nrho cov laminated manufacturing.
Covlub rotorthiabstatornyob rau hauv ib lub cev muaj zog yog tsim los ntawm ntau pua laminated thiab koom nrog nyias hluav taws xob hlau los xij, uas txo cov eddy tam sim no poob thiab nce efficiency, thiab ob leeg yog coated nrog rwb thaiv tsev ntawm ob sab los laminate cov hlau thiab txiav tawm eddy tam sim no ntawm cov khaubncaws sab nraud povtseg nyob rau hauv daim ntawv thov lub cev muaj zog. . Feem ntau, cov hlau hluav taws xob yog riveted lossis welded los xyuas kom meej lub zog ntawm lub laminate. Kev puas tsuaj rau cov txheej txheem rwb thaiv tsev los ntawm cov txheej txheem vuam tuaj yeem ua rau txo qis hauv cov khoom sib nqus, kev hloov pauv hauv microstructure, thiab kev qhia txog cov kev ntxhov siab uas seem, ua rau nws muaj kev sib tw zoo rau kev cuam tshuam ntawm cov khoom siv dag zog thiab cov khoom sib nqus.
