Ukuthenga iimagnethi? Nantsi iNtetho eNgqongileyo oyidingayo

Ukuntywila nzulu kwihlabathi leMagnethi eZisigxina

Ukuba ukhangela iimagnethi zeprojekthi, mhlawumbi uzifumene untywila ngeespekthi zobugcisa kunye neepayithi zokuthengisa ezikhazimlayo. Imigaqo efana ne "N52" kunye "notsalo lwamandla" iphoswa ngeenxa zonke, kodwa yintoni eyona nto ibalulekileyo xa kuziwa kwisicelo sokwenyani? Masitsibe i-fluff kwaye siye ezantsi kwishishini. Le asiyothiyori yencwadi yesikhokelo kuphela; bubuchule obufunyenwe nzima ukusuka kumashumi eminyaka yokukhetha oomazibuthe bemisebenzi esemhlabeni, kugxilwe kwihashe lomsebenzi oya kulifikelela kakhulu: umazibuthe webha ye-neodymium.

Uluhlu lweMagnet-Ukuchola iqela lakho

Cinga ngeemagnethi ezisisigxina njengeentlobo ezahlukeneyo zezixhobo zokwakha-nganye inosetyenziso lwayo, kwaye ukukhetha engalunganga yindlela eqinisekileyo yokuphelisa iprojekthi yakho.

Iimagnethi zeCeramic (Ferrite):Umqolo othembekileyo wemagnethi yehlabathi. Uya kuzibona njengemagnethi emnyama kwizipika zemoto yakho okanye ubambe ikhabhathi yakho yokusebenzela ivaliwe. Inzuzo yabo enkulu? Azikwazi ukumelana nomhlwa kwaye zinokubetha emzimbeni. Urhwebo-off? Amandla azo anobubuthe anele nje, akancomeki. Zisebenzise xa uhlahlo lwabiwo-mali luqinile kwaye awudingi amandla omsebenzi onzima.

Alnico Magnets:Ukhetho lwakudala. Yenziwe nge-aluminiyam, i-nickel, kunye ne-cobalt, ziyindlela yokuya kuzinzo lobushushu obuphezulu-yiyo loo nto ubukho bazo kwiigeyiji zesixhobo esidala, ii-pickups ze-premium guitar, kunye ne-sensor ezikufutshane neenjini. Kodwa banobuthathaka: i-jolt enzima okanye i-magnetic field echasayo ingabahlutha i-magnetism yabo. Zikwaxabiseke ngakumbi kunemagnethi zeceramic, zibenza ukuba bakhethe kwi-niche.

Iimagnethi zeSamarium Cobalt (SmCo):Ingcali yomsebenzi ogqithisileyo. Ngaba ufuna umazibuthe ogculela ubushushu obungama-300°C okanye ube sesichengeni sekhemikhali? Kuko oku. Imizi-mveliso ye-aerospace kunye neyokhuselo ihlawula iprimiyamu ngenxa yokomelela kwayo okungakoyiswayo, kodwa kwi-95% yemisebenzi yemizi-mveliso, igqithisa.

Iimagnethi zeNeodymium (NdFeB):Intshatsheli yamandla engenakuphikiswa. Sisizathu sokuba ii-electronics zethu zicuthe kwaye izixhobo zemizi-mveliso zibe namandla ngakumbi-cinga imagnethi encinci kodwa inamandla kwidrill yakho engenantambo. Isilumkiso esibalulekileyo: Ezi magnethi zithandwa kakhulu ngumhlwa. Ukuyishiya ingagqunywanga kufana nokushiya intsimbi ngaphandle kwemvula; isiphelo esikhuselayo asiyondlela yokukhetha-yinto efunekayo ukuze uphile.

IiNkcukacha ezichaziweyo – UMtyholi kwiiNkcukacha

Nantsi indlela yokufunda i-spec sheet efana ne-pro ofunde kwiimpazamo ezibiza kakhulu.

ITrap yeBanga (N-rating):Kuyinyani ukuba inani elingu-N eliphezulu (elifana no-N52) lithetha amandla angaphezu kweliphantsi (N42). Kodwa nantsi imfihlelo yecandelo: amabanga aphezulu anzima kakhulu. Ndikhe ndabona iimagnethi ze-N52 ziqhekeka phantsi komothuko wokuba i-N42 inokugqabhuka ngaphandle komkrwelo. Rhoqo kunokungabikho, umazibuthe we-N42 othe kratya lolona khetho lukrelekrele, luqina ngakumbi-ufumana amandla okutsala afanayo ngaphandle kobuthathaka.

Tsala amandla:ILab Fairy Tale vs. Shop Floor Reality: Loo nombolo yamandla yokutsala amehlo iphuma kwiphepha lenkcazo? Ilinganiswa kwibhloko yentsimbi egqibeleleyo, engqindilili, egudileyo kwisipili kwilebhu elawulwa yimozulu. Isicelo sakho? Ngumqadi opeyintwe, ojije kancinci ogqunywe kwisikali sokusila. Kwihlabathi lenene, amandla okwenene okubamba anokuba sisiqingatha samabango ekhathalogu. Umgaqo: Sebenzisa i-specs ukuthelekisa, kodwa themba kuphela iprototype evavanyiweyo kumphezulu wakho wokwenyani.

Ukumelana nobushushu:Ukunyanzeliswa Kulawula Kakhulu: Ukunyanzeliswa "ngamandla okuhlala emazibuthe" -yinto eyithintelayo ekuphulukaneni nemagnethi xa evezwe kubushushu okanye ngaphandle kwemagnethi. Ukuba umazibuthe wakho uya kuba kufutshane nenjini, kwindawo yokuwelda, okanye kuphahla lwentsimbi olutshiswa lilanga, kufuneka ukhethe ibakala lobushushu obuphezulu (jonga izimamva ezifana no-'H', 'SH', okanye 'UH'). Iimagnethi ze-neodymium zesiqhelo ziqala ukonakaliswa unaphakade xa amaqondo obushushu enyuka ngaphezu kwe-80°C (176°F).

Ukukhetha i-Coating eLungileyo-Sizixhobo:

I-Nickel (Ni-Cu-Ni):Ukugqitywa komcimbi osemgangathweni. Iyacwebezela, iyafikeleleka, kwaye ilungile ngokugqibeleleyo ukomile, ukusetyenziswa kwangaphakathi-cinga iindibano zemveliso okanye izixhobo ezicocekileyo zegumbi.

Epoxy/Polymer Coating:Umfo onzima weengubo. Yimaleko ehlala i-matte, ehlala inemibala kwaye imelana nokutshiphuzwa, izinyibilikisi, kunye nokufuma okungcono kakhulu kunenikeli. Kuyo nayiphi na into esetyenziswa ngaphandle, kwivenkile yomatshini, okanye kufutshane neekhemikhali, i-epoxy yeyona nto isebenzayo. Kunjengokuba ixhego elikwivenkile ethengisa izinto ezenziwe ngobuqhetseba lathi: “Ezikhazimlayo zikhangeleka zintle ebhokisini.

Kutheni le Bar Magnet ngumhlobo wakho osenyongweni

Iidiski kunye nezangqa zinokusetyenziswa kwazo, kodwa ezithobekileyoumazibuthe webha ye-neodymiumsesona sakhiwo sokugqibela seprojekthi yeshishini kunye ne-DIY ngokufanayo. Ubume bayo obuxande buzisa ubuso obude, obusicaba bobububuthe—obulungele ukomelela, amandla okubamba afanayo.

Apho Ifumana Ukugcinwa Kwayo:Ijometri yayo yenzelwe ulwakhiwo lwesiko. Zilungelelanise ukuze zenze ibha yokutshayela kazibuthe yokuchola inkunkuma yentsimbi. Zifakele kwisimo se-aluminiyam yesiko ukuze ubambe iinxalenye ngexesha lokuwelda. Zisebenzise njengezitshizi kwizinzwa ezikufutshane. Imiphetho yazo ethe tye ikuvumela ukuba wakhe amacwecwe ashinyeneyo, anamandla emagnethi ukuze uphakamise okanye ubambe imithwalo enzima.

Iinkcukacha ze-Bulk-Order Wonke umntu Uyayikhumbula:Xa u-odola amaqhekeza angama-5,000, awukwazi ukuthi "ibar ye-intshi ezi-2." Kufuneka ucacise ukunyamezelwa kwe-dimensional (umzekelo, 50.0mm ±0.1mm). Ibhetshi yeemagnethi ezinobungakanani obungahambelaniyo ayizukulingana kwindawo yakho yokubeka, kwaye oko kunokonakalisa yonke indibano. Ababoneleli abahloniphekileyo baya kulinganisa kwaye baqinisekise olu kunyamezela-musa ukuhlawula ngaphantsi.

Ukhuseleko: Akuthetheki:

         I-Pinch/Crush Ingozi:Iimagnethi ezinkulu ze-neodymium zinokutsiba kunye namandla awoneleyo okutyumza amathambo. Ngalo lonke ixesha zisingatha zodwa kwaye ngononophelo olukhulu.

         Umngcipheko womonakalo we-elektroniki:Ezi magnethi zinokuwonakalisa ngokupheleleyo amakhadi okuthenga ngetyala, ii-hard drives, kunye nezinye imidiya yemagnethi. Ngaphezu koko, banokuphazamisa ukusebenza kwe-pacemaker ukusuka kumgama omde ngokumangalisayo.

         Izikhokelo zokuGcina:Gcina iimagnethi ze-neodymium ngendlela egcina ukuba bangaphathani-izahluli zekhadibhodi okanye iindawo zokubeka ezisebenza ngokugqibeleleyo kule nto.

         Isilumkiso soKhuseleko kwiWelding:Lo ngumgaqo ongaxoxiswana ngawo: Ungaze usebenzise umazibuthe we-neodymium naphi na kufutshane ne-arc ye-welding esebenzayo. Intsimi yamagnetic inokuthumela i-arc ibhabha ngendlela enobundlobongela, engalindelekanga, ibeka i-welder engozini enkulu.

Ukusebenza noMboneleli-Kumahlakani

Injongo yakho ayikokuthenga nje oomazibuthe; kukusombulula ingxaki. Phatha umthengisi wakho njengeqabane kule nkqubo. Yabelana ngeenkcukacha zegritty yeprojekthi yakho: “Oku kuya kubhawulwa kwifreyim yefolokhwe, kugqunywe kulwelo olwenziwa ngamanzi, kwaye isebenze ukusuka ku -10°C ukuya kuma-50°C.”

Umthengisi olungileyo uyakukubuza imibuzo elandelayo ukuqonda iimfuno zakho. Omhle uya kubuyisela umva ukuba wenza impazamo: "Ucele i-N52, kodwa ngalo mthwalo wothusayo, masithethe nge-N42 ngedyasi ejiyileyo ye-epoxy." Kwaye rhoqo-rhoqo-fumana iisampuli zomzimba kuqala. Zibeke kwi-wringer kwindawo okuyo: zicwilise kulwelo, zibeke esichengeni sobushushu obugqithisileyo, zivavanye de zisilele. Loo makhulu ambalwa eedola echithwe kwiiprototypes yeyona inshorensi iphantsi onokuthi uyithenge ngokuchasene nentlekele yemveliso enamanani amahlanu.

Umgca ongezantsi: Ngokujonga ngaphaya kwee-specs zomgca omenyezelayo kwaye ugxile ekomeleleni okusebenzayo, ukuchaneka, kunye nentsebenziswano yokwenyani kunye nomthengisi wakho, uya kuwasebenzisa amandla apheleleyo emagnethi-ingakumbi umazibuthe webha ye-neodymium-ukwakha izisombululo ezingenamandla nje kuphela, kodwa ezithembekileyo nezikhuselekileyo kwiminyaka ezayo.

Ngaba ungathanda ukuba ndongeze icandelo kwiiflegi ezibomvu ukunqanda xa ukhetha umthengisi wemagnethi ukwenza inqaku liphelele ngakumbi kubafundi bakho?
