Injini Mumuchina: Mashandisirwo Anoita Magnet Kadiki Muhupenyu Hwemazuva Ano

Kunyange hazvo izwi rekuti "rare earth permanent magnet" richishandiswa zvakanyanya, magineti e-neodymium, kureva magineti e-neodymium iron boron (NdFeB) permanent magnets, ndiwo anonyanya kushandiswa pakushanda. Chinhu chikuru chetekinoroji yayo chiri mukugadzirwa kwayo kwesimba remagineti rakawanda, izvo zvinoita kuti ikwanise kupa simba remagineti rakasimba muhuwandu hushoma, zvichiita kuti ive chinhu chinofarirwa pakushandiswa kwemazuva ano kwesimba repamusoro.

Kune avo vanoda kuita zvehunyanzvi—vanoita basa guru munyika yedu. Simba ravo guru isanganiswa iri nyore asi inochinja: vanobatanidza simba guru remagineti kuita chimiro chakamanikana zvinoshamisa. Ibasa rakangwara rakashandiswa nemainjiniya pazvinhu zvese kubva pakuvaka mapurazi makuru emhepo kusvika pakuisa ruzha rwemhando yepamusoro munzeve dzako. Simba ravo mumafekitori rakasiyana; kupinda kwavo chinyararire muhupenyu hwedu hwezuva nezuva ndiko kunotaura nyaya inonakidza zvikuru.

Zvishamiso Zvekurapa

Muzvipatara nemumarabhoritari, izvimaginetiinzira dzekuongorora zviri nyore. Michina yeMRI yakavhurika mativi, semuenzaniso, inowanzo tsiva mugero unotyisa nemagetsi e-neodymium akagadzirwa nemazvo, zvichigadzira simba remagineti rinodiwa nenzira inoderedza kuzvidya mwoyo kwevarwere vane claustrophobia. Uye hunyanzvi hahugumiri pakufungidzira muviri—vaongorori vava kuedza kushandisa masimba aya emagineti anodzora semagineti ema microscopic. Chinangwa? Kutungamira zvidimbu zvemishonga zvakananga kumabundu kana kukurudzira kuvandudzwa kwemapfupa, kugadzira nzira yekurapa kunoshanda nemazvo semupfuri wepfuti pane kupararira kwepfuti.

Kubata Kuseri kweRobhoti

Pafekitori, kuvimbika hakugone kutaurirana. Ruoko rwerobhoti rinodonhedza chikamu kana CNC mill rinotsvedza chishandiso rinogona kudhura zviuru. Ndipo panopinda magineti aya. Anopa kubata kusingazununguki nekukurumidza mumachucks nemidziyo yemagetsi. Uye mukati memamota eservo anoisa zvikamu ne micron-level accuracy here? Wakafungidzira—neodymium arrays yakawanda. Simba ravo risingaperi, risingazununguki ndiro rinoita kuti kudzokorora kwakakwana kwekugadzirwa kwemazuva ano kukwanisike.

Chombo Chakavanzika CheTekinoroji Chinoderera

Wakambozvibvunza here kuti sei zvishandiso zviri kuramba zvichiwedzera kutetepa asi zvichiwedzera simba? Tenda magneti ye microscopic neodymium. Matinji madiki aya anoshandura zvisingagoneki kuita zvezuva nezuva. Ndosaka speaker iri muma earbuds ako asina waya ichiburitsa bass, kuti foni yako inoshandura sei yambiro yedhijitari kuita vibration inobatika, uye zvinoita kuti smartwatch inzwe kana bhendi rayo rakabatana zvakanaka.Magineti madiki eNeodymium—— Ndivo vanopa simba guru re "mantra madiki, ari nani" ehunyanzvi.

Kubva kumotokari dzemagetsi kuenda kumotokari dzemhuri yako

Kuchinja kwemotokari dzemagetsi kunonyanya kukonzerwa nekuchinja kunoitwa nemagnet. Mota inofambisa EV zvakanaka kubva pakumira kusvika pa60 mph inoshandisa magineti e-neodymium akasimba, ayo anoshanda zvakanaka achisimudzira mamaira pachaji. Asi magineti aya haasi emotokari dzemangwana chete—akabatanidzwa mumotokari yaunayo nhasi. Anoshanda sedziviriro dzakanyarara mumabhureki ako ekudzivirira kukiya, achitarisa kumhanya kwevhiri kudzivirira kutsvedza kune njodzi. Ndiwo zvakare ruzha rwakanyarara rwechigaro chako chemagetsi uye kudzvanya kwakavimbika kwechidzitiro chemusuwo chakagadzirwa zvakanaka.

Mhepo, Mawati, uye Kushanda Zvakanaka

Kugadzirwa kwegridi yesimba rakachena kune simba guru mukugadzira magineti e-neodymium. Maturbine emhepo anotyaira zvakananga echizvarwa chitsva anosiya magiyagiya akaomarara, aine majenareta akareruka, akasimba akavakirwa pamaringi makuru emagineti e-neodymium. Dhizaini iyi yakangwara inoderedza kuputsika uye inoita kuti magetsi aenderane nemhepo yega yega. Ndiwo mashandiro emagineti akafanana anopa maEV mukana wavo wakanaka - zvichiratidza kuti mainjiniya akangwara anowanzo kugadzirisa matambudziko akawanda panguva imwe chete.

Kudzora Mabasa Akaoma Emaindasitiri

Munyika ine tsvina yezvinhu zvakagadzirwa uye kugadzirwa kwezvinhu zvinorema, magineti aya haashandiswi—kunyanya kana akagadzirwa nemibato yekushandisa chaiyo. Fungidzira magineti makuru anoronga pakati pemapellets egorosi kana epurasitiki, achitora zvidimbu zvesimbi zvinogona kukanganisa zvigadzirwa kana kukuvadza michina. Uyezve kune magineti anosimudza anoshandiswa mumayadhi esimbi, achisimudza magineti akawanda ane grip yakachengeteka isingazununguki—kunyangwe magetsi achikundikana. Kusiyana nemagineti, magineti aya anoshandisa simba regineti re neodymium, nekuchengetedzeka kunowedzerwa kuburikidza nesarudzo dzekugadzira nemaune: kusarudza magiredhi eN42 akasimba pane N52 brittle variant, kubatanidza magineti asingatsvedzeri rabha/TPE handles (akaedzwa akapfeka magirovhosi ebasa kuti ave nechokwadi chekunyaradzwa), uye kuisa epoxy coatings kurwisa ngura mumamiriro ekushanda akaoma. Kushivirira kwakasimba kunovimbisa kukodzera kwemibato zvakanaka, kudzivirira zvikamu zvakasununguka kana zvisina kumira zvakanaka zvinokonzera kukuvara kwebasa.

Kunyangwe kutenga kune simba remagineti

Nguva inotevera paunenge uri muchitoro chine mafashoni, nyatsotarisa. Bhodhi remenyu rinotaridzika zvakanaka, rinochinjika here kana kuti modular shelving unit? Rinogona kunge rakabatidzwa pamwe chete nemagineti madiki ane simba e neodymium. Mhinduro iyi iri nyore inopa vatengesi mukana wekushandura nzvimbo mumaminitsi, zvichiratidza kuti chinhu ichi chemhando yepamusoro chine hunyanzvi hwekutengesa.

Chii chiri paHorizon?

Remangwana remagineti aya harisi rekuwedzera simba chete—riri rekugadzira kugara kwenguva refu uye kusimudzira kugara kwenguva refu. Masayendisiti ezvekushandisa ari kutarisa zvakanyanya pakuwedzera kupisa kwavo uye kuramba ngura, vachizvigadzirisa kuti zvishande zvakanaka munzvimbo dzakaoma dzekushanda. Zvakanyanya kukosha, indasitiri iyi iri kuwedzera zvirongwa zvekudzokorodza, ichitungamira zvinhu izvi zvinokosha kune hupenyu hwakatenderera. Kune mashandisirwo akagadzirwa senge magineti akabatwa, kufambira mberi kuchave pakuvandudza nzira dzekubatanidza magineti—kudzivirira kupwanya muhari dzinopwanyika kana zvinonamira zvinokundikana kana kupisa—uye kuwedzera mikana yekugadzirisa maodha akawanda, kubva kusarudzo dzemavara emhando yepamusoro kusvika kuchimiro chakagadzirirwa zvishandiso zvakati. Chokwadi chimwe chete chinoramba chisingachinji: sezvo zvatinoda zvetekinoroji zvichichinja—zvichida kushanda zvakanaka, kushanda kwakangwara, uye magadzirirwo akatetepa—magineti aya asina kuzvikudza asi ane simba achabata basa rawo sechinosimudzira kufambira mberi, chisingawanzoonekwi, chisingaonekwe.

Mungade here kuti ndinyore runyorwa rwemaodha akawanda emagineti e neodymium akagadzirwa? Rugwaro urwu ruchaunganidza zvinhu zvakakosha uye zvinhu zvekuchengetedza kubva mugwaro iri, zvichigadzira chishandiso chiri nyore chekutarisa kune vatengi vemaindasitiri panguva yekutenga kwavo.
