Ingabe uzibuthe unawo amakhulu kangakanani amandla okudonsa?Abanye abantu bacabanga ukuthi omazibuthe be-NdFeB bangadonsa izinto izikhathi ezingama-600 njengesisindo sazo.Ingabe lokhu ngempela?Ingabe ikhona indlela yokubala yokumunca uzibuthe?Namuhla, ake sikhulume "Ngamandla Adonsayo" wezibuthe.
Ekusetshenzisweni kozibuthe, ukuguquguquka kazibuthe noma ukuminyana kazibuthe kuyinkomba ebaluleke kakhulu yokulinganisa ukusebenza (ikakhulukazi kumamotho).Kodwa-ke, kwezinye izinkambu zohlelo lokusebenza, njengokuhlukaniswa kazibuthe nokudoba kazibuthe, i-flux kazibuthe ayisona isilinganiso esisebenzayo sokuhlukanisa noma umthelela wokudonsa, futhi amandla adonsa uzibuthe ayinkomba esebenza kangcono.
Amandla adonsayo kazibuthe abhekisela esisindweni se-ferromagnetic material engakhangwa uzibuthe.Ithintwa ngokuhlanganyela ukusebenza, ukuma, ubukhulu kanye nebanga elikhangayo likazibuthe.Alikho ifomula yezibalo yokubala ukukhanga kukazibuthe, kodwa singakala inani lokukhanga kazibuthe ngedivayisi yokulinganisa ukukhanga kazibuthe (ngokuvamile ukulinganisa ukudonsa kukazibuthe bese sikuguqulela esisindweni), njengoba kuboniswe esithombeni esilandelayo.Amandla okudonsa uzibuthe azokwehla kancane kancane ngokwanda kwebanga lento ekhangayo.
Uma usesha ukubala kwamandla kazibuthe ku-Google, amawebhusayithi amaningi azobhala "ngokusho kokuhlangenwe nakho, amandla kazibuthe we-NdFeB uzibuthe cishe izikhathi ezingu-600 njengesisindo sawo (izikhathi ezingu-640 nazo ezibhaliwe)".Ukuthi lokhu okwenziwayo kulungile noma cha, sizokwazi ngokuhlolwa.
Ozibuthe be-Sintered NdFeB n42 abanomumo nosayizi abahlukene bakhethiwe esivivinyweni.I-surface coating kwakuyi-NiCuNi, eyayifakwe uzibuthe ngokuqondisa kokuphakama.Amandla amakhulu okuqina (i-N pole) kazibuthe ngamunye alinganiswa futhi aguqulwa abe isisindo esihehayo.Imiphumela yokulinganisa imi kanje:
Akunzima ukuthola emiphumeleni yokulinganisa:
- Isilinganiso sesisindo odonsa bobumo nobukhulu obuhlukene abangasidonsa ngesisindo sabo siyahlukahluka kakhulu.Ezinye zingaphansi kwezikhathi ezingu-200, ezinye izikhathi ezingaphezu kuka-500, kanti ezinye zingafinyelela izikhathi ezingaphezu kuka-3000.Ngakho-ke, izikhathi ezingama-600 ezibhalwe ku-inthanethi azilungile ngokuphelele
- Ku-Cylinder noma I-Disc Magnet enobubanzi obufanayo, ukuphakama kokuphakama, isisindo esikhulu esingasidonsa, futhi amandla kazibuthe ngokuyisisekelo alingana nobude.
- Ku-Cylinder noma i-Disc Magnet yobude obufanayo (iseli eluhlaza okwesibhakabhaka), uma ubukhulu bebubanzi buba bukhulu, isisindo sikhulu esingasidonsa, futhi amandla kazibuthe ngokuyisisekelo alingana nobubanzi.
- Ububanzi nobude be-Cylinder noma i-Disc Magnet (yellow cell) enevolumu efanayo nesisindo kuhlukile, futhi isisindo esingaheha siyahlukahluka kakhulu.Ngokuvamile, uma isiqondiso sikazibuthe sithatha isikhathi eside, kukhulu ukumunca
- Kumagnethi anevolumu efanayo, amandla kazibuthe awalingani ngempela.Ngokwezimo ezihlukahlukene, amandla kazibuthe angase ahluke kakhulu.Ngakolunye uhlangothi, ngokufanayo, omazibuthe abaheha isisindo esifanayo sezinto ze-ferromagnetic bangase babe nokwakheka okuhlukile, amavolumu nezisindo.
- Kungakhathaliseki ukuthi yiluphi uhlobo lomumo, ubude besiqondiso sokuma budlala indima enkulu kakhulu ekunqumeni amandla kazibuthe.
Okungenhla ukuhlolwa kwamandla okudonsa odonsa bebanga elifanayo.Kuthiwani ngamandla adonsayo ozibuthe abahlukile bebanga elihlukile?Sizohlola futhi siqhathanise kamuva.
