Zipangizo zazikulu zopangira ma cores a mota ndi mapepala achitsulo a silicon. Pakadali pano, omwe amagwiritsidwa ntchito kwambiri ndi mapepala 470, 600 ndi 800 omwe amakulungidwa mozizira, ndipo mapepala 470 ndi 600 amagwiritsidwa ntchito kwambiri m'magalimoto amphamvu kwambiri.
1. Kutayika kochepa.
Kutayika kwa core pa ma frequency enaake ndi mphamvu ya maginito ndi chizindikiro chachikulu cha mapepala achitsulo amagetsi. Kutayika kwa core kumakhala ndi magawo awiri: kutayika kwa hysteresis ndi kutayika kwa eddy current. Kutayika kwa hysteresis ndi kugwiritsa ntchito mphamvu komwe kumachitika chifukwa cha kusintha kwa maginito kwa core, komwe kumakhudzana ndi kapangidwe ka zinthu ndi kukula kwa tirigu, ndipo kumatha kuyimiridwa ndi dera la hysteresis loop. Kutayika kwa hysteresis ndi kutayika kwa kukana komwe kumachitika chifukwa cha eddy current yomwe imapangidwa panthawi ya kusintha kwa maginito kwa core, komwe kumakhudzana ndi kukana ndi makulidwe a chinthucho. Chifukwa chake, kuti achepetse kutayika kwa core, mapepala achitsulo amagetsi amakhala ndi makulidwe ochepa komanso kukana kwakukulu.
2. Mphamvu ya maginito yapamwamba kwambiri.
Pamene mphamvu ya maginito ikukwera, gawo lozungulira la maginito limakhala laling'ono kwambiri ngati mphamvu ya maginito ikhalabe yokhazikika, zomwe zimapulumutsa mkuwa womwe umagwiritsidwa ntchito poyendetsa maginito ndikuchepetsa kukula kwa injini.
3. Katundu wabwino wopaka laminating.
Mapepala achitsulo amagetsi ayenera kukhala olimba mokwanira, osaphwanyika kwambiri kapena ofewa kwambiri. Pamwamba pake payenera kukhala posalala, lathyathyathya, komanso ofanana mu makulidwe (ndi kufunikira kwa kuwongolera kusiyana kwa mbale), zomwe zimathandiza kuboola nkhungu ndikukweza kuchuluka kwa ma stacking coefficient. Nkhungu yomweyo ingagwiritsidwe ntchito pa mapepala achitsulo ozungulira ozizira, ndipo nthawi yake yogwira ntchito imatha kukulitsidwa kwambiri poyerekeza ndi mapepala achitsulo ozungulira otentha. Mapepala ena achitsulo ozungulira ozizira okhala ndi zokutira zopanda organic kapena zachilengedwe amatha kuwonjezera kuchuluka kwa kuboola pa nkhungu pafupifupi nthawi khumi mutamaliza kupukutira kamodzi. ●Kutsika mtengo komanso kosavuta kugwiritsa ntchito. Kuphatikiza pa zofunikira zomwe zili pamwambapa, ma mota ena nthawi zambiri amakhala ndi zofunikira zapamwamba pazinthu zoyendetsera maginito. Mwachitsanzo, kulephera pang'ono kwa maginito ndi kukula pang'ono kwa maginito. Zofunikira izi ndizosiyanasiyana ndipo ziyenera kuganiziridwa mokwanira.
●Chitsulo cha silicon
Chitsulo chopangidwa ndi silicon, chomwe chimakulungidwa kukhala mapepala opyapyala. Kawirikawiri chimatchedwa pepala lachitsulo la silicon. Kutengera ndi momwe amapangira, chimagawidwa m'magulu a pepala lachitsulo la silicon lozunguliridwa ndi moto (lomwe lachotsedwa pang'onopang'ono) ndi pepala lachitsulo la silicon lozunguliridwa ndi ozizira. Pepala lachitsulo la silicon lozunguliridwa ndi ozizira likhoza kugawidwanso m'mitundu yolunjika ndi yosalunjika. Pakadali pano, mapepala achitsulo a silicon nthawi zambiri amaperekedwa mu mawonekedwe a pepala. Kuti akonze mphamvu zamaginito za pepala lachitsulo la silicon ndikuchepetsa mphamvu yake yodula, mapepala achitsulo a silicon akunyumba athandizidwa ndi annealing mu mphero yozungulira.
●Chitsulo chopanda silikoni
Pakati pa injini pamagwiritsa ntchito mapepala achitsulo a silicon m'malo mwa mapepala achitsulo otsika mpweya ndi chitsulo choyera. Uku kunali kupita patsogolo kwakukulu m'mbiri. Mapepala achitsulo a silicon otsika mpweya adathandizira magwiridwe antchito a injini ndikuchepetsa kukula kwake. Tsopano, m'malo mogwiritsa ntchito mapepala achitsulo a silicon, mapepala achitsulo otsika mpweya (omwe amadziwikanso kuti mizere yachitsulo yamagetsi otsika mpweya kapena mizere yachitsulo yamagetsi yachitsulo choyera mpweya) amagwiritsidwa ntchito kupanga ma cores a mota zazing'ono chifukwa mapepala achitsulo otsika mpweya omwe amapangidwa ndiukadaulo wamakono ndi osiyana ndi mapepala achitsulo otsika mpweya. Sangokhala ndi mphamvu yayikulu ya maginito komanso amataya chitsulo mofanana ndi mapepala achitsulo a silicon. Ma mota ang'onoang'ono a AC opangidwa ndi mapepala achitsulo otsika mpweya amatha kuchepetsa kukula, kuchepetsa kulemera, ndikuchepetsa mtengo. Kuphatikiza apo, chifukwa mapepala achitsulo otsika mpweya ndi ofewa, amatha kuwonjezera liwiro lobowola ndikuwonjezera moyo wa nkhungu. Tsopano, mapepala achitsulo otsika mpweya amagwiritsidwa ntchito kwambiri ngati zinthu zofunika kwambiri zamagalimoto ang'onoang'ono m'maiko akunja. M'maiko otukuka, kugwiritsa ntchito kwawo kumawerengera pafupifupi 50-60% ya kuchuluka kwa mapepala achitsulo amagetsi.
Pakadali pano, pali zochitika ziwiri pomwe fakitale yamagalimoto imagwiritsa ntchito mapepala achitsulo osakhala a silicon. Choyamba ndi chakuti mapepala achitsulo osakhala a silicon atagubuduzidwa mozizira amabowoledwa mwachindunji m'mapepala, kenako chithandizo cha annealing chimachitikira ku fakitale yamagalimoto; china ndi chakuti mapepala achitsulo ophatikizidwa omwe amaperekedwa ndi fakitale yamagalimoto amabowoledwa ndikugwiritsidwa ntchito mwachindunji ndi fakitale yamagalimoto. Mapepala achitsulo osakhala a silicon ndi zipangizo zoyendetsera maginito kwambiri, ndipo mphamvu yawo yolowetsa maginito ndi kutayika kwake zimakhala zovuta kwambiri kupsinjika kwa makina. Chifukwa chake, mutabowoledwa komanso musanagwiritse ntchito, kuchotsa kupsinjika ndi njira yofunika kwambiri yowongolera magwiridwe antchito a maginito. Chithandizo cha kutentha cha mapepala achitsulo osakhala a silicon chimafuna zida zapadera zochizira kutentha, koma mafakitale ambiri amagalimoto mdziko lathu alibe mikhalidwe yotereyi. Ili ndi vuto lomwe liyenera kuthetsedwa pogwiritsa ntchito mapepala achitsulo osakhala a silicon.
● Kuchuluka kwa silicon ndi silicon yodetsedwa zimakhudza kwambiri magwiridwe antchito a mapepala achitsulo a silicon. Mukawonjezera silicon ku chitsulo, mphamvu yolimbana nayo imawonjezeka, ndipo imathandizanso kulekanitsa kaboni yodetsedwa yoopsa. Kawirikawiri, chitsulo choyera chikawonjezedwa ndi silicon, mphamvu ya maginito yolowetsa imachepa pang'ono, koma kutayika kwa chitsulo kumachepa kwambiri. Pamene kuchuluka kwa silicon kumawonjezeka, kuuma ndi kusweka kumawonjezeka, zomwe zimabweretsa zovuta pakugudubuza, kuponda, kumeta, ndi kukonza makina. Pakadali pano, kuchuluka kwa silicon m'mapepala achitsulo a silicon nthawi zambiri sikupitirira 4.5%. Ngati kuchuluka kwa silicon kuli kokwera, zimakhala zovuta kuchita kugudubuza ndi kukonza.
●Kukhuthala.Poganizira kuti kutayika kwa mphamvu ya eddy mu chitsulo chapakati kumagwirizana ndi sikweya ya makulidwe a pepala lachitsulo, pamtundu womwewo wa pepala lachitsulo la silicon, makulidwe ake akachepa, kutayika kwa chitsulo chapakati kumakhala kochepa, koma nthawi yopangira chitsulo chapakati imawonjezeka ndipo kuchuluka kwa stacking kumachepa. Kawirikawiri, ma mota amagwiritsa ntchito mapepala achitsulo a silicon okhala ndi makulidwe a 0.5 mamilimita, ndipo pamene zofunikira pakutayika kwa chitsulo chapakati cha majenereta akuluakulu a turbine ya nthunzi zimakhala zolimba kwambiri, mapepala achitsulo a silicon okhuthala a 0.35 mamilimita amagwiritsidwa ntchito.
●Kupsinjika maganizo.Pa nthawi yocheka, kuyika zinthu pamodzi, kapena kukulunga pakati pa chitsulo, kupsinjika kumapangidwa, zomwe zimawononga mphamvu ya maginito ndikuwonjezera kutayika kwa chitsulo. Pafupifupi milimita imodzi mbali zonse ziwiri za mzere wodula (wosweka), malo otsala a stress owoneka bwino amapangidwa. Kawirikawiri, chithandizo cha annealing chingagwiritsidwe ntchito kuti muchotse kupsinjika ndikubwezeretsa mphamvu yoyambirira ya maginito; mphamvu ya maginito ya mapepala achitsulo a silicon opangidwa ndi chitsulo chozizira kwambiri imakhala yolimba kwambiri kupsinjika.
