Neiyo miniaturization yemidziyo yemagetsi uye kufarirwa kweasina waya yekuchaja tekinoroji, magineti magineti akave zvinhu zvakakurumbira mumunda wemagetsi evatengi nekuda kwekureruka kwavo uye kugadzikana. Kuita kwayo uye hupenyu hwehupenyu zvakanyanya zvinoenderana nekusarudzwa kwezvinhu. Ichi chinyorwa chinozotanga kubva kune epakati zvikamu zvekuongorora izvo zvikuru zvekushandisa uye maitiro ekushandisa emagetsi magineti.
Magnetic zvinhu: inotongwa neNdFeB uye SmCo
Iyo yakakosha kukwezva kwemagineti yekubatanidza inobva kune anogara magineti. Idzo dzazvino sarudzo dzakanyanya ndiNdFeB (NdFeB) uye SmCo (SmCo). Iine simba remagineti chigadzirwa chinosvika ku50MGOe, magineti eNdFeB ave sarudzo yekutanga kune yakakwirira adsorption mapikicha uye anoshandiswa zvakanyanya mukutenga zvigadzirwa zvemagetsi senge mbozha nhare uye mahedhifoni. Nekudaro, ayo ari nyore oxidation maitiro anoda kuchengetedzwa ne nickel plating kana epoxy resin coating. Samarium cobalt magineti anoita zvirinani munzvimbo dzakanyanya tembiricha (tembiricha yekushanda inogona kusvika 350 dhigirii) uye inokodzera michina yemaindasitiri kana mota dzemagetsi.
Conductive contacts: copper alloy uye yakakosha simbi plating
Iyo conductive chikamu chinowanzo shandisa copper alloy substrate (senge phosphor bronze kana beryllium mhangura) nekuti ine zvese zvakakwirira conductivity uye mechanical simba. Kunatsiridza kusamira kwekusapfeka uye kusaita ngura, danda resimbi yakakosha segoridhe (Au) kana sirivheri (Ag) rakaputirwa pamusoro. The gold plating layer inochengetedza-term contact kugadzikana uye inokodzera kukwirira-kuvimbika kwakadai semidziyo yekurapa; sirivheri plating inonyanya kuwanda mumagetsi evatengi nekuda kwekudhura kwayo. Vamwe vagadziri vanowedzerawo nickel (Ni) chipingamupinyi chigadziko pasi peplating kudzivirira kuwedzera kwekusangana kwekupokana kunokonzerwa nemhangura ion kutama.
Insulating shell: engineering mapurasitiki uye LCP zvinhu
Iyo shell zvinhu zvinofanirwa kufunga nezve insulation, kupisa kupisa uye kugadzikana kwedimensional. Polycarbonate (PC) nenaironi (PA) isarudzo dzechinyakare, ukuwo liquid crystal polymer (LCP) yave zvishoma nezvishoma sarudzo yekutanga kune yakakwirira-frequency signal transmission connectors nekuda kwekudzikira kwayo dielectric uye kuramba tembiricha (kunyungudika kuri pamusoro pe300 degrees ). Pamusoro pezvo, zvimwe zvigadzirwa zvinoshandisa flame-mapurasitiki asingadzoreki ane mwero wemoto weUL94 V-0 kuzadzisa zviyero zvekuchengetedza.
Ramangwana Trends: Zvikareruka uye Zvine Hushamwari Zvishandiso
Sezvo zvinodiwa zvezvishandiso zvemagetsi zvisingaremi zvichiwedzera, vamwe vagadziri vatanga kuyedza maginezi alloys kana carbon fiber reinforced plastics (CFRP) semagoko zvinhu. Panguva imwe cheteyo, mitemo yezvakatipoteredza inosimudzira kushandiswa kwehalogen{1}zvinodzoreredza moto zvisina haro uye zvinhu zvinogadzikiswazve, zvakaita semapurasitiki-akavakirwa, ari padanho rekuedzwa.
Iko kusarudzwa kwezvinhu zvemagineti ekubatanidza kunokanganisa zvakananga maitiro avo uye anoshanda mamiriro. Kubva pa-magineti ekushanda zvakanaka kusvika pakurongeka, chinongedzo chega chega chekuvandudza zvinhu chiri kufambisa kusimukira kwehunyanzvi hwekubatanidza michina yemagetsi.
