Ndi zinthu ziti zomwe zimagwiritsidwa ntchito poyatsira mu stator ndi rotor ya injini?

Therotorya mota ya DC imakhala ndi chitsulo chopangidwa ndi laminated. Pamene rotor imazungulira mu mphamvu yamagetsi yamagetsi, imapanga magetsi mu koyilo, yomwe imapanga mafunde a eddy, omwe ndi mtundu wa kutayika kwa maginito, ndipo kutayika kwamakono kwa eddy kumabweretsa kutaya mphamvu. Zinthu zingapo zimakhudza momwe mafunde a eddy amatha kutaya mphamvu, monga mphamvu yamagetsi, makulidwe azinthu zamaginito, komanso kuchuluka kwa maginito. Kukaniza kwa zinthu zamakono kumakhudza momwe mafunde a eddy amapangidwira, mwachitsanzo, pamene zinthuzo zimakhala zolemera kwambiri, malo ozungulira amawonjezeka, zomwe zimapangitsa kuti eddy awonongeke panopa. Zida zowonda zimafunikira kuti muchepetse gawo lodutsa. Pofuna kuti zinthuzo zikhale zowonda kwambiri, opanga amagwiritsa ntchito mapepala ochepa kwambiri otchedwa laminations kuti apange maziko a armature, ndipo mosiyana ndi mapepala owonjezera, mapepala ochepetsetsa amatulutsa kukana kwakukulu, zomwe zimapangitsa kuti pakhale mphamvu zochepa.

Kusankhidwa kwa zinthu zomwe zimagwiritsidwa ntchito popangira ma motor lamination ndi chimodzi mwazinthu zofunika kwambiri pakupanga ma mota, ndipo chifukwa cha kusinthasintha kwawo, zina mwazosankha zodziwika bwino ndi chitsulo chozizira chozizira chamoto ndi chitsulo cha silicon. Ma silicon apamwamba (2-5.5 wt% silicon) ndi zitsulo zopyapyala (0.2-0.65 mm) ndi zida zofewa zamaginito zama motor stator ndi rotor. Kuphatikizika kwa silicon ku chitsulo kumapangitsa kuti pakhale kukakamiza kocheperako komanso kukhazikika kwapamwamba, ndipo kuchepa kwa makulidwe a mbale zoonda kumabweretsa kutayika kwapakali pano.
Cold adagulung'undisa laminated zitsulo ndi chimodzi mwa zinthu zotsika mtengo pakupanga misa ndipo ndi imodzi mwazitsulo zodziwika bwino. Zinthuzo ndizosavuta kusindikiza ndipo zimapanga zochepa zovala pa chida chosindikizira kusiyana ndi zipangizo zina. Opanga ma motor anneal motor laminated zitsulo ndi filimu ya okusayidi yomwe imawonjezera kukana kwa interlayer, kupangitsa kuti ikhale yofanana ndi zitsulo zotsika za silicon. Kusiyana pakati pa chitsulo chopangidwa ndi chitsulo chamoto ndi chitsulo chozizira ndi chitsulo chosungunulira ndi kukonza zitsulo (monga annealing).
Chitsulo cha silicon, chomwe chimadziwikanso kuti chitsulo chamagetsi, ndi chitsulo chochepa cha carbon chokhala ndi silicon pang'ono chomwe chimawonjezeredwa kuti muchepetse kuwonongeka kwa eddy pakatikati. Silicon imateteza ma stator ndi thiransifoma cores ndikuchepetsa kugwedezeka kwa zinthu, nthawi pakati pa m'badwo woyamba wa maginito ndi m'badwo wake wonse. Kamodzi ozizira adagulung'undisa ndi bwino zochokera, zinthu ndi wokonzeka ntchito lamination. Childs, pakachitsulo zitsulo laminates ndi insulated mbali zonse ziwiri ndi zaunjika pamwamba wina ndi mzake kuchepetsa eddy mafunde, ndi Kuwonjezera pakachitsulo pa aloyi aloyi zimakhudza kwambiri moyo wa zida zopondaponda ndi kufa.
Chitsulo cha silicon chimapezeka mu makulidwe ndi magiredi osiyanasiyana, ndi mtundu wabwino kwambiri kutengera kutayika kwachitsulo chovomerezeka mu watts pa kilogalamu. Gulu lililonse ndi makulidwe amakhudza kutsekemera kwapamwamba kwa aloyi, moyo wa chida chosindikizira, ndi moyo wa imfa. Monga chitsulo chozizira chozizira chamoto, kutsekemera kumathandizira kulimbitsa chitsulo cha silicon, ndipo njira yodutsamo imachotsa mpweya wochuluka, motero kuchepetsa nkhawa. Kutengera ndi mtundu wa chitsulo cha silicon chomwe chimagwiritsidwa ntchito, chithandizo chowonjezera cha gawoli chimafunikira kuti muchepetse kupsinjika.
Kuzizira kozizira kopangira zitsulo kumawonjezera ubwino wambiri pazinthu zopangira. Kupanga kozizira kozizira kumachitika pa kutentha kapena kutentha pang'ono, zomwe zimapangitsa kuti njere zachitsulo zikhale zotalikirana pozungulira. Kuthamanga kwapamwamba komwe kumagwiritsidwa ntchito pazinthu zopangira zinthu kumayendera zofunikira zokhazikika zachitsulo chozizira, zomwe zimapangitsa kuti pakhale malo osalala komanso miyeso yolondola komanso yosasinthasintha. Kuzizira kozizira kumayambitsanso zomwe zimatchedwa "strain harding", zomwe zimatha kuwonjezera kuuma mpaka 20% poyerekeza ndi zitsulo zosagwedezeka m'makalasi otchedwa full hard, theka-hard, quarter hard and surface rolled. Kugudubuza kumapezeka mu maonekedwe osiyanasiyana, kuphatikizapo kuzungulira, lalikulu ndi lathyathyathya, ndi m'makalasi osiyanasiyana kuti zigwirizane ndi mitundu yosiyanasiyana ya mphamvu, mphamvu ndi ductility zofunika, ndipo mtengo wake wotsika akupitiriza kukhala msana wa onse laminated kupanga.
Therotorndistatormugalimoto amapangidwa kuchokera ku mazana a laminated ndikulumikizana ndi zitsulo zopyapyala zamagetsi, zomwe zimachepetsa kuwonongeka kwa eddy pano ndikuwonjezera magwiridwe antchito, ndipo onse amakutidwa ndi kutchinjiriza mbali zonse ziwiri kuti asungunuke chitsulo ndikudula mafunde a eddy pakati pa zigawo zomwe zimagwiritsidwa ntchito pamagalimoto. . Childs, magetsi zitsulo ndi riveted kapena welded kuonetsetsa makina mphamvu laminate. Kuwonongeka kwa zokutira zotchingira kuchokera pakuwotcherera kungayambitse kuchepa kwa maginito, kusintha kwa ma microstructure, komanso kuyambitsa zovuta zotsalira, zomwe zimapangitsa kuti zikhale zovuta kwambiri kusagwirizana pakati pa mphamvu zamakina ndi maginito.
