I-Sided Single vs Double Sided vs 2 in 1 Magnet: Yini Engcono?

Ake siqhubekele phambili:Uma kukhulunywa ngamamagnethi e-neodymium, usayizi owodwa (noma isitayela) AKUFANELEKI wonke. Ngichithe iminyaka ngisiza izitolo, abakhiqizi, kanye nabantu abathanda izinto zokuzijabulisa ukuthi bakhethe imagnethi efanele umsebenzi—kodwa ngibabone bechitha imali kunketho “ecwebezelayo” esikhundleni saleyo esebenza ngempela. Namuhla, sihlukanisa izitayela ezintathu ezidumile: ohlangothi olulodwa, ohlangothi olulodwa (yebo, lokho kufaka phakathi omagnethi be-neodymium abahlangothi olulodwa), kanye nomagnethi angu-2 ku-1. Ekugcineni, uzokwazi kahle ukuthi iyiphi efanele indawo ku-toolkit yakho.

Okokuqala, Ake Sicacise Isitayela Ngasinye

Ngaphambi kokuba singene empikiswaneni yokuthi “yikuphi okungcono”, masiqinisekise ukuthi sonke sisekhasini elifanayo. Akukho magama alula—khuluma ngokuqondile ngalokho okwenziwa yimagnethi ngayinye, nokuthi kungani ibalulekile.

Ama-Magnets Ahlangothini Olulodwa: Izisekelo Zomsebenzi

Omaginethi abanohlangothi olulodwa yibo kanye abazwakala benjalo: wonke amandla abo kazibuthe agxile endaweni eyodwa eyinhloko, kanti ezinye izinhlangothi (kanye nokusekela) zenzelwe ukuba nokudonsa okuncane. Cabanga ngesibambi sakho samathuluzi kazibuthe esijwayelekile noma umaginethi wesiqandisi (yize omaginethi abanohlangothi olulodwa bezimboni benamandla amakhulu). Ngokuvamile bahlanganiswa nepuleti lokusekela elingelona ugesi ukuze bagxile ekushintsheni kohlangothi lokusebenza, ukuvimbela ukukhangwa okungahlosiwe ensimbini eseduze.

Ngake ngaba neklayenti elalisebenzisa omaginethi abanohlangothi olulodwa ukubamba amashidi ensimbi ngesikhathi sokushisela. Ekuqaleni, bakhononda “ngobuthakathaka”—kwaze kwaba yilapho siqaphela ukuthi babewafaka emuva, besebenzisa uhlangothi olungeyona olunozibuthe. Okufanele ukwenze? Omaginethi abanohlangothi olulodwa balula, kodwa kufanele uhloniphe ukwakheka kwabo okuqondene nohlangothi olulodwa.

Omaginethi beNeodymium Abamaceleni Amabili: Ukuguquguquka Okubili Kobuso

Manje, ake sixoxe ngamamagnethi e-neodymium ahlangothini oluphindwe kabili—iqhawe elingakadunyiswa lezinhlelo zokusebenza ezidinga ukusebenzisana kwamagnetic ezinhlangothini ezimbili. Lawa mamagnethi e-NdFeB akhethekile aklanywe ukuze alethe ukukhanga okunamandla noma ukuxosha ezindaweni ezimbili ezikhethiwe, kuyilapho egcina ukuvuza okuseceleni kuncane (ngokuvamile ngezingxenye ezingezona zamagnetic emaphethelweni). Ngokungafani namamagnethi ahlangothi olulodwa, awakuphoqi ukuthi ukhethe “ingaphambili” noma “emuva”—asebenza kuzo zombili izinhlangothi.

Kunezinhlobo ezimbili eziyinhloko: i-opposite-pole (enyakatho kolunye uhlangothi, eningizimu kolunye) yokubamba izingxenye ezimbili zensimbi ndawonye, ​​kanye ne-some-pole (enyakatho-enyakatho noma eningizimu-eningizimu) yezidingo zokuxosha njengokudonsa noma ukugoqa. Ngincome omaginethi be-neodymium abanezinhlangothi ezimbili abaphambene ne-pole eklayenti lokupakisha ngonyaka odlule—bathathe indawo yeglue kanye ne-staples yokuvala amabhokisi esipho, banciphisa isikhathi sokuhlangana ngo-30% futhi benza amabhokisi aphinde asetshenziswe. Ukunqoba-ukunqoba.

Icebiso Elihle: Omaginethi be-neodymium abanezinhlangothi ezimbili bagcina zonke izinzuzo eziyinhloko ze-NdFeB—umkhiqizo onamandla aphezulu, ukuphoqelela okunamandla, kanye nosayizi omncane—kodwa ukwakheka kwabo okunezinsika ezimbili kubenza bangabi usizo emisebenzini yobuso obubodwa. Ungenzi izinto zibe nzima kakhulu ngokuzisebenzisa lapho umaginethi onezinhlangothi ezimbili uzokwenza khona.

Ama-Magnets angu-2 kwangu-1: I-Hybrid Contender

Ama-magnet amabili ku-1 (abizwa nangokuthi ama-magnet aguqukayo) angama-chameleon eqembu. Akuvumela ukuthi ushintshe phakathi kokusebenza okunezinhlangothi ezimbili kanye nokusebenza okunezinhlangothi ezimbili, ngokuvamile ngesivikelo noma isilayidi esingenama-magnetic esinyakazayo. Slayida isivikelo ngendlela eyodwa, bese kuba nohlangothi olulodwa kuphela olusebenzayo; slayida ngenye, bese zombili izinhlangothi zisebenza. Zithengiswa njengezixazululo "zonke-in-one", kodwa ngithole ukuthi ziyindlela yokushintshana—uthola ukuguquguquka, kodwa ulahlekelwa amandla amancane uma kuqhathaniswa nezinketho ezizinikele ezihlangothini olulodwa noma ezimbili.

Iklayenti lokwakha lizame omayibuthe abangu-2 ku-1 ukuze lifake izibonakaliso zesikhashana. Basebenzele izimpawu zangaphakathi, kodwa uma bevezwa emoyeni nasekudlidlizeni, isilayida sasishintsha, sivale uhlangothi olulodwa. Ukuze kusetshenziswe isikhathi eside, omayibuthe abazinikele basanqoba—kodwa abangu-2 ku-1 bakhanya ngemisebenzi esheshayo neguquguqukayo.

Ikhanda Nekhanda: Yikuphi Okukufanele?

Ake sihlukanise izinto ezibalulekile—amandla okudonsa, ukusebenziseka kalula, izindleko, kanye nokusebenza kwangempela—ukuze uyeke ukuqagela.

Amandla Okudonsa Nokusebenza Kahle

Omaginethi abanohlangothi olulodwa banqoba amandla angaphekiwe, agxilile endaweni eyodwa. Njengoba yonke i-flux iqondiswe ebusweni obubodwa, baletha ukudonsa okuningi nge-cubic inch kune-2 ku-1s, futhi bavame ukwenza kangcono kunamaginethi e-neodymium anohlangothi olulodwa emisebenzini eqondiswe ohlangothini olulodwa. Omaginethi abanohlangothi olulodwa bahlukanisa i-flux phakathi kwezindawo ezimbili, ngakho-ke amandla abo ohlangothini ngalunye aphansi—kodwa awahlulwa uma udinga isenzo esiphindwe kabili. Ama-2 ku-1s abuthakathaka kakhulu kwalawa amathathu, njengoba indlela yokuvikela ingeza ubukhulu futhi inciphisa ubuningi be-flux.

Ukusebenziseka Nokufaneleka Kohlelo Lokusebenza

Ohlangothini olulodwa: Kuhle kakhulu ekufakeni amathuluzi, izimpawu, noma izingxenye lapho udinga khona ukukhangwa endaweni eyodwa kuphela. Kuhle kakhulu ekushiseleni, ekusebenzeni ngokhuni, noma ezitolo zezimoto—noma yikuphi ukukhangwa okungahlosiwe kuyinkathazo.

I-neodymium enamacala amabili: Ilungele ukupakisha (ukuvalwa kwamagnetic), izingxenye ze-elekthronikhi (izinzwa ezincane, ama-motor amancane), noma imisebenzi yokuhlanganisa okudingeka ihlanganise izingxenye ezimbili zensimbi ngaphandle kwezinamathiselo. Futhi ziyindlela engcono kakhulu yemikhiqizo yasekhaya ehlakaniphile njengezivalo zeminyango yamagnetic noma izesekeli zendlu yokugezela.

2 ku-1: Kuhle kakhulu kubantu abathanda izinto zokuzijabulisa, izisebenzi ezihambayo, noma imisebenzi ephansi kokucindezeleka lapho udinga ukuguquguquka khona. Cabanga ngemibukiso yezohwebo (ukushintsha phakathi kokufaka izimpawu ohlangothini olulodwa kanye nokubamba izibonisi ohlangothini olulodwa) noma amaphrojekthi e-DIY anezidingo eziguquguqukayo.

Izindleko Nokuqina

Omaginethi abasemaceleni odwa bashibhile kakhulu—umklamo olula, izindleko zokukhiqiza eziphansi. Omaginethi abasemaceleni omabili babiza ngaphezulu ngo-15-30% ngenxa yobuchwepheshe bokumaginethi obunembile kanye nezinto zokwakha, kodwa bayakufanelekela ukusetshenziswa okukhethekile. Omaginethi ababili kwaba-1 babiza kakhulu, ngenxa yezingxenye zabo ezihambayo—futhi lezo zingxenye zivame ukuguga ngokuhamba kwesikhathi, ikakhulukazi ezindaweni ezinzima (cabanga ngomswakama, uthuli, noma amazinga okushisa aphezulu).

Khumbula: Izinga lokushisa libulala buthule bonke omaginethi be-neodymium. Omaginethi be-neodymium abajwayelekile abasemaceleni amabili baphatha kufika ku-80°C (176°F); uma uwasebenzisa eduze kokushisela noma ama-engine bay, faka intwasahlobo ukuze uthole amazinga okushisa aphezulu. Omaginethi abasemaceleni owodwa banemikhawulo yokushisa efanayo, kuyilapho ama-2 kwangu-1 engahluleka ngokushesha ekushiseni ngenxa yezingxenye zawo zepulasitiki.

Isinqumo: Yeka Ukuphishekela “Okuhle Kakhulu”—Khetha Okufanele

Akukho "onqobayo" ojwayelekile lapha—kukhona kuphela ofanele umsebenzi wakho othize. Ake senze kube lula:

Khetha uhlangothi olulodwa uma udinga amandla aphezulu obubanzi obulodwa futhi ufuna ukugwema ukukhanga ohlangothini. Kuyindlela engabizi kakhulu ezitolo eziningi zezimboni.

Khetha i-neodymium enamacala amabili uma udinga ukusebenzisana okubili (ukubamba izingxenye ezimbili ndawonye, ​​ukuxosha, noma ukusebenza okubili okuhlangene). Zishintsha kakhulu izinto zokupakisha, izinto zikagesi, kanye nezinto zasekhaya ezihlakaniphile.

Khetha okubili kokukodwa kuphela uma ukuguquguquka kungenakuxoxiswana ngakho, futhi uzimisele ukudela amandla nokuqina okuthile. Kuyithuluzi elikhethekile, hhayi elithatha indawo yamagnethi azinikele.

Amathiphu Okugcina Ochwepheshe (Kusukela Ezifundweni Ezinzima)

1. Hlola ngaphambi koku-oda ngobuningi. Ngake ngavuma i-oda lamayunithi angu-5,000 lamagnethi e-neodymium ahlangothi zombili ngaphandle kokuhlola endaweni yokugcina izimpahla emanzi yeklayenti—izembozo ezigqwalile zonakalise u-20% webhetshi. Izembozo ze-epoxy zidlula i-nickel plating ezindaweni ezinzima.

2. Ungadlulisi izinga. Ama-magnet e-neodymium anezinhlangothi ezimbili ze-N52 azwakala emangalisa, kodwa ayaphuka. Eziningi zezinhlelo zokusebenza, i-N42 inamandla (empeleni) futhi ihlala isikhathi eside.

3. Ukuphepha kuqala. Onke amamagnethi e-neodymium aqinile—anezinhlangothi ezimbili angacindezela iminwe noma asule amakhadi okhiye okuphepha kude. Wagcine kude nezinto zikagesi bese usebenzisa amagilavu ​​​​ngesikhathi sokuphatha.

Empeleni, ukukhetha okuhle kulandela isimiso esithi “ifomu lilandela umsebenzi.” Vumela uhlelo lwakho lokusebenza oluthile lunqume ukuthi imagnethi ye-neodymium engu-2-in-1 enezinhlangothi ezimbili, noma ehlanganisiwe ingcono kakhulu—umgomo ukufeza umphumela oyifunayo ngokuthembeka okungapheli.
