Mafotokozedwe Ofunika a Maginito a Mphete ya Neodymium

Tisanadutse pansi pa fakitale, tiyeni tikambirane mfundo imodzi. Simungathe kupanga maginito a mphete molondola ngati zinthuzo zili zosalala.
Kufotokozera kukula kwa maginito a mphete yoyenera ndi fyuluta yoyamba pakati pa gawo lomwe limagwera mu cholumikizira chanu ndi lomwe limadzaza kapena kugwedezeka. Tidzabwereranso ku zolekerera pambuyo pake - koma dziwani kuti gawo lililonse lotsikira limadalira zojambula zanu.

 

Chidule cha Njira Yopangira Magnet ya Neodymium Ring

Kukonzekera Zinthu

Zimayamba ndi neodymium yaiwisi, chitsulo, ndi boron - kuphatikiza zinthu zingapo zowonjezera monga dysprosium kapena terbium kuti zisatenthe. Chosakanizacho chimasungunuka mu uvuni wa vacuum induction, kenako chimaponyedwa mu flakes zopyapyala. Flakes zimenezo zimasanduka ufa wolimba.

Apa ndi pomwe ngodya zimadulidwa: opanga otsika mtengo amagwiritsa ntchito zoyezera zosakwanira kapena kusiya kuyera. Zotsatira zake? Maginito a mphete omwe amayesa bwino koma amachita 15–20% pansi pa zomwe zafotokozedwa. Timatumiza gulu lililonse la zinthu zopangira ku labu yakunja. Ngati mpweya kapena mpweya uli ndi 0.05%, timakana. Zimenezo zimamveka ngati zosafunikira mpaka mutasintha mphete 10,000 chifukwa zinataya mphamvu mu mota yotentha.

Njira Yoyeretsera (Kugwiritsa Ntchito Zitsulo za Ufa)

Ufa wosalala umakanikizidwa mu die pansi pa mphamvu yamphamvu ya maginito. Pa maginito ozungulira, gawo limenelo limalumikiza tinthu tating'onoting'ono - kulinganiza kumeneku kumatsimikizira mwachindunji mphamvu yanu yomaliza ya maginito. Kenako ma compact "obiriwira" okanikizidwa amalowa mu uvuni woyaka.

Kutenthetsa zinthuzo kumatentha zinthuzo mpaka kufika pofika posungunuka (pafupifupi 1060–1100°C) mu vacuum kapena mpweya wopanda mpweya. Tinthu timeneti timalumikizana pamodzi, zomwe zimapangitsa kuti gawolo lichepe ndi pafupifupi 15–20% mwanjira yolamulidwa. Kuchepa kumeneku n'kodziwikiratu - koma pokhapokha ngati kutentha kwa uvuni wanu ndi nthawi zikugwiritsidwa ntchito. Kuthamanga kwa 10°C kwa ola limodzi kungapangitse mphete zomwe zimakhala ndi mabowo ambiri kapena zosweka kwambiri.

Pambuyo poyatsa, maginito amaziziritsidwa kenako amakonzedwanso pang'onopang'ono. Izi zimapangitsa kuti mphamvu yomaliza ya maginito isamagwire ntchito. Mukasiya njira yoyeretsera, maginito anu azidzichotsera okha mphamvu ya maginito m'malo ofunda.

Kupanga ndi Kupanga

Maginito a mphete opangidwa ndi sintered amachokera mu uvuni wolimba komanso wofooka koma osati pamlingo womaliza. Machining amapangidwa ndi zida zophimbidwa ndi diamondi kapena machining amagetsi otulutsa mpweya (EDM) chifukwa kabodi wokhazikika sungadule.

M'mimba mwake wamkati (ID) ndi m'mimba mwake wakunja (OD) zimadulidwa kuti zigwirizane ndi kulekerera. Pa mphete yanthawi zonse ya mafakitale, timasunga ±0.05mm pa ID ndi OD. Pakugwiritsa ntchito molondola monga mphete zolembera, zimatsikira mpaka ±0.01mm. Ndikukumbukira gulu pomwe kasitomala adatchula "kulekerera kwanthawi zonse" - kenako adadandaula kuti kuthamanga kwa 0.1mm kudapangitsa kuti bearing yawo itenthe kwambiri. Tsopano nthawi zonse timafunsa kuti: gawo lolumikizirana ndi chiyani, ndipo malo olowera ndi chiyani?

 

Njira Yopangira Magnetization ndi Coating

Magnetization ya Axial vs Radial

Apa ndi pomwe maginito ozungulira amakhala othandiza kapena osathandiza. Kukhazikitsa maginito si njira yokhazikika - iyenera kufotokozedwa.

- Kuyika maginito pa malo olumikizirana a axial kumatanthauza kuti mizati ya kumpoto ndi kum'mwera ili pankhope ziwiri zathyathyathya. Izi ndizofala pa maginito olumikizirana, mphete zogwirira, ndi ma speaker assemblies.
- Kutulutsa maginito a radial kumatanthauza kuti mitengoyo ili pa mainchesi amkati ndi akunja - nkhope imodzi ili kumpoto, nkhope inayo ili kum'mwera, koma mphamvu ya maginito imatuluka mozungulira. Izi ndi zomwe mukufuna pa ma rotor a DC opanda brushless, maginito, ndi masensa ena.

Ndaona mainjiniya akuyitanitsa mphete 5000 zokhala ndi maginito ozungulira, koma anazindikira kuti anaiwala kuuza fakitale kuchuluka kwa ndodo (ndodo ziwiri, ndodo zinayi, ndodo zisanu ndi zitatu). Fakitale inapanga zonse ziwiri. Mphetezo zinagwira ntchito, osati zogwiritsidwa ntchito. Nthawi zonse tsimikizirani njira ya maginito ozungulira pogwiritsa ntchito chithunzi chomwe chikuwonetsa momwe ndodo imayendera poyerekeza ndi njira kapena chizindikiro.

Njira Zophikira ndi Zotsatira Zake

Maginito a mphete ya NeodymiumNdi pafupifupi 60% ya chitsulo - zimachita dzimbiri kwa maola ambiri mumlengalenga wonyowa. Kuphimba sikokongoletsa.

- NiCuNi (nikeli ya nikeli yamkuwa): Yogwiritsidwa ntchito m'mafakitale ouma. Yolimba, yoyendetsa mpweya, komanso yopyapyala (10–20µm). Koma kukanda kamodzi ndi dzimbiri kumayamba.
- Epoxy: Yokhuthala (25–50µm), yosayendetsa mpweya, komanso yolimba kwambiri ku mchere wothira ndi chinyezi. Ndi yoyipa koma yolimba. Timaigwiritsa ntchito poyesa zinthu zakunja ndi ntchito zam'madzi.
- Zinc: Yotsika mtengo komanso yodzipereka. Yabwino kwambiri popangira zinthu mkati zomwe sizimaundana.
- Passivation / phosphating: Yopyapyala kwambiri - yokhayo ya maginito omwe adzakulungidwa kapena kupangidwanso, chifukwa zomatira zimamatira bwino pamalo ouma komanso oboola.

Kasitomala wina anasiya kugwiritsa ntchito epoxy ndipo anagwiritsa ntchito nickel pa mphete za sensa ya pampu yamadzi. Patatha miyezi itatu, mphete iliyonse inali ikutuluka dzimbiri. Chitsimikizo cha chitsimikizo chinawononga ndalama zambiri kuposa gulu lonse. Musaganize - yesani chitsanzo pamalo omwe muli.

 

Kuwongolera Ubwino mu Kupanga Maginito

Kulekerera ndi Kuyesa kwa Miyeso

Maginito aliwonse a mphete amawunikidwa - koma si maginito onse a fakitale omwe amawunikidwa mofanana. Timagwiritsa ntchito muyeso wowunikira wokha wa OD, ID, ndi makulidwe pa 100% ya maoda apadera. Micrometer ya laser imasanthula gawo lililonse mkati mwa sekondi imodzi. Mphete iliyonse yomwe ili kunja kwa kulekerera komwe kwavomerezedwa imayikidwa mu chidebe chosungiramo zinthu zakale.

Koma apa pali msampha: kulolerana kumagwira ntchito pa zonse zitatumiyeso paderaMphete ikhoza kukhala ndi OD yabwino kwambiri, ID yomwe ndi yaying'ono kwambiri ya 0.03mm, komanso makulidwe omwe ndi 0.1mm. Idzalepherabe kusonkhana. Ndicho chifukwa chake muyenera kufotokoza miyeso yomwe ndi yofunika kwambiri komanso yomwe ndi yofunikira.

Kuyesa Magwiridwe Antchito ndi Kulimba

Kuthamanga kwa maginito kumayesedwa ndi cholembera cha Helmholtz kapena mita ya Gauss pamalo angapo ozungulira mpheteyo. Pa mphete zokhala ndi maginito a axial, timayang'ana munda wapakati ndi munda womwe uli pafupi ndi m'mphepete. Pa mphete zokhala ndi maginito a radially, timazungulira gawolo ndikuyang'ana kusinthasintha kwa pole-to-pole - kusiyana kopitilira 3% kumatanthauza kuti kulumikizana panthawi yokanikiza kunali kosagwirizana.

Kuyesa kutentha ndi gawo lina. Timatenga mphete zisanu kuchokera mu gulu lililonse, kuziyika mu uvuni pa kutentha komwe mwasankha (monga 120°C) kwa maola awiri, kuziziziritsa, ndikuyesanso kuchuluka kwa madzi. Ngati zitaya zoposa 5% ya zomwe zidatulutsa poyamba, gululo limakanidwa. Imeneyo ndi mayeso wamba omwe ogulitsa ambiri "otsika mtengo" amanyalanyaza chifukwa zimatenga nthawi ndikutaya zinthu.
