Kuseri kweZviitiko: Magadzirirwo Anoitwa Magneti eNeodymium Akaumbwa NeU

Mumaindasitiri uko simba remagineti, chinangwa chekutungamira, uye dhizaini diki zvisingakurukurwe,Magineti e-neodymium akaita seUkumira semagamba asina kurumbidzwa. Asi magineti aya ane simba, ane chimiro chakasiyana anoberekwa sei? Rwendo kubva paupfu husina kubikwa kuenda kubhiza remagineti rinoshanda zvakanyanya ibasa guru resainzi yezvinhu, mainjiniya akanyanya, uye kutonga kwakanaka kwemhando. Ngatipindei mufekitori.

Zvishandiso: Nheyo

Zvese zvinotanga ne "NdFeB" triad:

• Neodymium (Nd): Nyeredzi yezvinhu zvisingawanzoitiki zvepasi, zvichiita kuti simba remagineti risingaenzaniswi rivepo.
• Simbi (Fe): Musana wemusana.
• Boron (B): Iyo inosimbisa simba, inowedzera kumanikidzwa (kuramba kudziviswa kwesimba remagineti).

Zvinhu izvi zvinosanganiswa, zvonyungudutswa, uye zvinotonhodzwa nekukurumidza kuita zvidimbu, zvobva zvakuyiwa kuita upfu hwakatsetseka, hwakakura se micron. Chinonyanya kukosha ndechekuti upfu hunofanira kunge husina oxygen (huchigadziriswa mugasi/vacuum isina simba) kudzivirira oxidation inokuvadza mashandiro emagineti.

Danho 1: Kumanikidza - Kuumba Remangwana

Upfu hunoiswa mumaforoma. Kune magineti ane chimiro cheU, nzira mbiri dzekudzvanya dzinonyanya kushandiswa:

1. Kudzvanya kweIsostatic:
   • Upfu hwakaputirwa muforoma inochinjika.
   • Inomanikidzwa zvakanyanya (10,000+ PSI) kubva kumativi ese.
   • Inogadzira nzvimbo dzisina chinhu dzakaita semambure dzine huremu hwakafanana uye magnetic alignment.
2. Kudzvanya kweTransverse:
   • Simba remagineti rinogadzirisa zvidimbupanguvakudzvanya.
   • Zvakakosha pakuwedzera simba remagineti(BH)yakakwirirapadivi pemapango eU.

Nei zvichikosha: Kurongeka kwezvikamu kunosarudza simba remagineti—U-magnet isina kurongeka inorasikirwa nekushanda zvakanaka kwe >30%.

Danho rechipiri: Kupisa - "Moto Unobatanidza"

Zvikamu zvakadzvanywa "zvakasvibira" zvinopinda muchoto chekupisa chevacuum:

• Dzinodziiswa kusvika ≈1080°C (pedyo nenzvimbo yekunyunguduka) kwemaawa.
• Zvidimbu zvinobatana kuita chimiro chakasimba uye chakasimba.
• Kutonhodza kunononoka kunovhara muchimiro chekristaro.

Dambudziko: Maumbirwo eU anowanzo kupetana nekuda kwekupararira kwehukuru husina kuenzana. Dhizaini yechimiro uye ma curve chaiwo ekupisa zvakakosha kuchengetedza kugadzikana kwehukuru.

Danho rechitatu: Kugadzira Machining - Kunyatsorongeka Mumakomba Ese

NdFeB yakapfava haina kusimba (sezvakaita ceramic). Kugadzira U kunoda hunyanzvi hwekushandisa dhaimani:

• Kukuya: Mavhiri akaputirwa nedhaimani anocheka makumbo emukati nekunze kusvika pakukwanisa kuenzana kwe ±0.05 mm.
• Waya EDM: Kune maU-profiles akaomarara, waya yakachajwa inopfungaidza zvinhu nekupfava nema micron akarurama.
• Kukwesha: Mipendero yese inokweshwa kuti isatsvedze uye inodzivirira magnetic flux.

Chokwadi chinonakidza: Tsvina yekukuya yeNdFeB inobvira zvakanyanya! Masisitimu ekutonhodza anodzivirira sparks uye anotora zvidimbu kuti zvidzokororwe.

Danho rechina: Kukombama - Kana Magnets Asangana neOrigami

Imwe nzira yekushandisa maU-magnets makuru:

1. Mabhuroko erectangular anopisirwa pasi uye anokuyiwa.
2. Inodziiswa kusvika ≈200°C (pasi pekupisa kweCurie).
3. Kukombama kwe "U" nenzira ye hydraulic kunofa zvisina kurongeka.

Unyanzvi: Kukurumidza = kutsemuka. Kutonhora zvakanyanya = kutsemuka. Tembiricha, kumanikidzwa, uye mheto zvinofanirwa kuenderana kudzivirira kutsemuka kudiki kunopedza simba remagineti.

Danho rechishanu: Kupfeka - Nhumbi dzehondo

NdFeB isina chinhu inokurumidza kuora. Kufukidza hakuchinjiki:

• Kuisa simbi mu electroplating: Nickel-copper-nickel (Ni-Cu-Ni) triple layers dzinodzivirira ngura zvakasimba.
• Epoxy/Parylene: Yekushandisa pakurapa/kwezvakatipoteredza uko maion esimbi asingabvumidzwe.
• Hunyanzvi: Goridhe (zvemagetsi), Zinc (inodhura zvishoma).

Dambudziko reU-Shape: Kufukidza curve yemukati yakasimba zvakaenzana kunoda mabara akagadzirwa nehunyanzvi kana marobhoti ekuisa spray systems.

Danho rechitanhatu: Kugadzira Magneti - "Kumuka"

Magineti inowana simba rayo rekupedzisira, ichidzivirira kukuvara panguva yekubata:

• Yakaiswa pakati pemakoiri makuru anofambiswa ne capacitor.
• Yakaiswa pamunda we pulsed > 30,000 Oe (3 Tesla) kwema milliseconds.
• Kutungamira kwemunda kwakatarwa kwakanangana nehwaro hweU, zvichibatanidza matanda pamigumo.

Chinhu chikuru: MaU-magnets anowanzoda magnetization ine matanda akawanda (semuenzaniso, matanda anochinjana kumeso kwemukati) kuti ashandiswe ne sensor/motor.

Danho rechinomwe: Kudzora Hunhu - Kupfuura Mamita eGauss

Magineti ese eU anoedzwa zvine hutsinye:

1. Gaussmeter/Fluxmeter: Inoyera nzvimbo yepamusoro uye huwandu hwemvura inoyerera.
2. Muchina wekuyera weCoordinate (CMM): Unoongorora kururama kwehukuru hwe micron.
3. Kuedzwa kweMunyu: Kunosimbisa kugara kwenguva refu kwejira (semuenzaniso, kuramba kwemaawa anopfuura 48-500).
4. Kuedza Kudhonza: Pakubata magineti, zvinosimbisa simba rekunamira.
5. Kuongorora Kukombama kweDemagnetization: Inosimbisa (BH)max, Hci, HcJ.

Zvikanganiso? Kunyangwe kutsauka kwe2% zvinoreva kurambwa. Maumbirwo eU anoda kukwana.

Chikonzero nei U-Shape Ichida Unyanzvi Hwepamusoro-soro

1. Kunyanya Kushushikana: Kukombama nemakona injodzi yekutyoka.
2. Kusimba kweFlux Path: Maumbirwo asina kuenzana anowedzera zvikanganiso zvekuenzanisa.
3. Kufanana Kwekuputira: Makomba emukati anobata mabhurumu kana mavanga matete.

Mhedziso: Kwatinosangana Neunyanzvi Painjiniya

Nguva inotevera paunoona magineti eU-shaped neodymium achisimbisa mota inomhanya zvikuru, achichenesa simbi dzakadzokororwa, kana kuti achigonesa kufambira mberi kwekurapa, yeuka: kutenderera kwayo kwakanaka kunovanza nyaya yekurongeka kwemaatomu, kupisa kwakanyanya, kunyatsoita madhaimani, uye kusimbiswa kusingaperi. Izvi hazvisi zvekugadzira chete—kukunda kwakanyarara kwesainzi yezvinhu zvichipfuura miganhu yeindasitiri.

Unofarira magineti akaita seU-shaped here?Goveranai zvamunoda - isu tichaongorora nzira yekugadzira zvinhu.
