Imagnethi inawo kangakanani amandla okutsala? Abanye abantu bacinga ukuba iimagnethi zeNdFeB zinokutsala izinto ngamaxesha angama-600 njengobunzima bayo. Ngaba oku kanye? Ingaba ikhona indlela yokubala yokufunxa umazibuthe? Namhlanje, makhe sithethe "ngoMmandla wokuTloba" weemagnethi.
Ekusetyenzisweni kweemagnethi, i-magnetic flux okanye i-magnetic flux density ibaluleke kakhulu isalathisi sokulinganisa ukusebenza (ingakumbi kwiimotor). Nangona kunjalo, kwezinye iindawo zokusetyenziswa, ezifana nokwahlulwa kwemagnethi kunye nokuloba ngemagnethi, ukuqukuqela kwemagnethi ayingomlinganiselo osebenzayo wokwahlula okanye ukufunxa, kwaye amandla okutsalwa ngumagnethi sisalathiso esisebenza ngakumbi.
Amandla okutsala umazibuthe abhekiselele kubunzima bemathiriyeli yeferromagnetic enokutsalwa yimagnethi. Ichatshazelwa ngokudibeneyo yintsebenzo, imilo, ubungakanani kunye nomgama womtsalane wemagnethi. Akukho fomyula yemathematika yokubala umtsalane wemagnethi, kodwa sinokulinganisa ixabiso lomtsalane wemagnethi ngesixhobo sokulinganisa umtsalane wemagnethi (ukulinganisa ngokubanzi ukutsalwa kwemagnethi kwaye uyiguqule ibe nobunzima), njengoko kubonisiwe kulo mfanekiso ulandelayo. Amandla okutsala umazibuthe aya kuncipha ngokuthe ngcembe ngokunyuka komgama wento enomtsalane.
Ukuba ukhangela ukubala kwamandla kazibuthe kuGoogle, iiwebhusayithi ezininzi ziya kubhala "ngokutsho kwamava, amandla kazibuthe weNdFeB umazibuthe malunga namaxesha angama-600 njengobunzima bawo (amaxesha angama-640 nawo abhaliwe)". Ukuba la mava alungile okanye akunjalo, siya kwazi ngokusebenzisa imifuniselo.
Imagnethi ye-Sintered NdFeB n42 enemilo eyahlukeneyo kunye nobukhulu bakhethwa kuvavanyo. Ingubo engaphezulu yayiyiNiCuNi, eyayifakwe imagnethi kwicala lokuphakama. Amandla obunzima obuphezulu (i-N pole) yemagnethi nganye yalinganiswa kwaye yaguqulelwa kubunzima bomtsalane. Iziphumo zomlinganiselo zimi ngolu hlobo lulandelayo:
Akukho nzima ukufumana kwiziphumo zomlinganiselo:
- Umlinganiselo wobunzima oomazibuthe beemilo ezahlukeneyo kunye nobukhulu obunokutsalela kubunzima babo buyohluka kakhulu. Ezinye zingaphantsi kwamaxesha angama-200, ezinye zingaphezu kwamaxesha angama-500, kwaye ezinye zinokufikelela izihlandlo ezingaphezu kwama-3000. Ke ngoko, amaxesha angama-600 abhalwe kwi-Intanethi awachanekanga ngokupheleleyo
- Kwi-Cylinder okanye i-Disc Magnet enobubanzi obufanayo, ukuphakama kokuphakama, ubunzima obukhulu obunokutsala, kwaye amandla omagnetic alingana nobude.
- Kwi-Cylinder okanye iDisc Magnet yobude obufanayo (iseli eluhlaza okwesibhakabhaka), ubukhulu bedayamitha, kokukhona ubunzima obunokutsala, kwaye amandla kazibuthe ngokusisiseko alingana nobubanzi.
- I-diameter kunye nobude be-Cylinder okanye i-Disc Magnet (iseli etyheli) enomthamo ofanayo kunye nobunzima bohlukile, kwaye ubunzima obunokutsalwa buhluka kakhulu. Ngokubanzi, okukhona umkhombandlela wemagnethi ixesha elide, kokukhona ukufunxa kukhulu
- Kwimagnethi ezinomthamo ofanayo, amandla omagnetic awalingani. Ngokweemilo ezahlukeneyo, amandla ombane anokwahluka kakhulu. Ngokuchaseneyo, ngokufanayo, iimagnethi ezitsala ubunzima obufanayo bemathiriyeli ye-ferromagnetic zinokuba neemilo ezahlukeneyo, imiqulu kunye nobunzima.
- Nokuba loluphi uhlobo lweemilo, ubude besalathiso somkhomba-ndlela budlala indima enkulu ekumiseleni amandla kazibuthe.
Oku ngasentla luvavanyo lwamandla okutsala kwiimagnethi zebakala elifanayo. Kuthekani ngamandla okutsala umahluko weemagnethi zebakala elahlukileyo? Siza kuvavanya kwaye sithelekise kamva.
