Ukukhetha imathiriyeli yemagnethi efanelekileyo
Ukukhetha inketho yemagnethi efanelekileyo kwisicelo sakho kunokuba ngumngeni. Kukho izinto ezahlukeneyo zemagnethi onokukhetha kuzo, nganye ineempawu ezahlukeneyo zokusebenza. Njengomthengisi wemagnethi oqeqeshiweyo, ngamava ethu abanzi kwimagnethi, sinokukunceda wenze ukhetho olufanelekileyo.
Uluhlu olubanzi lwezinto ezikhoyo, kubandakanywa imagnethi ye-neodymium (NdFeB okanye umhlaba onqabileyo), iimagnethi zealnico (AlNiCo), i-samarium cobalt (SmCo ) okanye imagnethi yeferrite (i-ceramic). Ukongeza, kukho iinguqulelo ezahlukeneyo ezifana nemagnethi, iimagnethi eziguqukayo kunye neemagnethi ezibotshiweyo. Ukukhetha imathiriyeli efanelekileyo kungundoqo kwiprojekthi enempumelelo.
Zingaphi iindidi ezahlukeneyo zoomazibuthe ezikhoyo
Ukuhlelwa okulula kwezi magnethi kunokwenziwa ngokusekwe kukwakheka kweemagnethi ezahlukeneyo kunye nomthombo wemagnethi yazo. Iimagnethi ezihlala zimagnetic emva kwemagneti zibizwa ngokuba ziimagnethi ezisisigxina. Into echasene nale yi-electromagnetic. I-electromagnetic yimagnethi yethutyana esebenza kuphela njengomazibuthe osisigxina xa ikufutshane nemagnethi, kodwa iphulukane nesi siphumo ngokukhawuleza xa isusiwe.
Iimagnethi ezisisigxina zihlala zohlulwa zibe ziindidi ezine ngokwemathiriyeli yazo: NdFeB, AlNiCo, SmCo kunye neferrite.
I-Neodymium iron boron (NdFeB) - eyaziwa njenge neodymium iron boron okanye NEO umazibuthe - ziimagnethi zomhlaba ezinqabileyo ezenziwe ngealloying neodymium, iron kunye neboron, kwaye zezona magnethi zinamandla zikhoyo namhlanje. Ewe kunjalo, i-NdFeB inokwahlulwa ibe yi-NdFeB ene-sintered, i-NdFeB edityanisiweyo, inaliti yoxinzelelo i-NdFeB njalo njalo. Nangona kunjalo, ngokubanzi, ukuba asichazi ukuba loluphi uhlobo lwe-Nd-Fe-B, siya kubhekisa kwi-sintered Nd-Fe-B.
Samarium Cobalt (SmCo) -ekwaziwa ngokuba yi-rare earth cobalt, i-rare earth cobalt, i-RECo kunye ne-CoSm - azinamandla njengemagnethi ye-neodymium (NdFeB), kodwa zibonelela ngeenzuzo ezintathu ezinkulu. Iimagnethi ezenziwe kwi-SmCo zinokusebenza kuluhlu olubanzi lobushushu, zibe ne-coefficient ephezulu yobushushu kwaye ziyakwazi ukumelana nomhlwa. Ngenxa yokuba i-SmCo ibiza kakhulu kwaye ineepropati ezizodwa, i-SmCo isoloko isetyenziswa emkhosini kunye nezicelo ze-aerospace.
IAluminiyam-Nickel-Cobalt (AlNiCo) - Zonke izinto ezintathu eziphambili ze-AlNiCo - i-aluminium, i-nickel kunye ne-cobalt. Nangona ziyakwazi ukumelana nobushushu, zikhutshwa yimagnethi ngokulula. Kwezinye izicelo, zihlala zitshintshwa yi-ceramic kunye neemagnethi zomhlaba ezinqabileyo. I-AlNiCo ihlala isetyenziswa kubomi bemihla ngemihla kwizicelo ezimileyo kunye nezokufundisa.
Ferrite- Iimagnethi ezisisigxina zeCeramic okanye zeferrite zihlala zenziwe nge-sintered iron oxide kunye ne-barium okanye i-strontium carbonate kwaye azibizi kwaye kulula ukuvelisa ngokucofa okanye ukucinezela. Olu lolunye lwezona ntlobo zixhaphakileyo zemagnethi. Zomelele kwaye zinokukhutshwa ngokulula.
Iimagnethi ezisisigxina zinokwahlulwa ngokwezi ndidi zilandelayo ngokohlukana kweenguqulelo ezahlukeneyo:
I-Sintering-kukuguqulwa kwezinto ezinomgubo zibe yimizimba eshinyeneyo kwaye yinkqubo yendabuko. Abantu baye basebenzisa le nkqubo ixesha elide ukuvelisa i-ceramics, i-metallurgy powder, izinto eziphikisayo, izinto zokushisa eziphezulu, njl njl. Ngokubanzi, umzimba oshinyeneyo ofunyenwe ngokutshiza emva kokuba umgubo uxonxiwe yinto yepolycrystalline ene-microstructure. ebandakanya iikristale, i-vitreous humor kunye ne-pores. Inkqubo ye-sintering ichaphazela ngokuthe ngqo ubungakanani bengqolowa, ubungakanani bepore kunye nokumila kunye nokusabalalisa imida yengqolowa kwi-microstructure, leyo ichaphazela iipropati zezinto eziphathekayo.
Ukudityaniswa - Ukudityaniswa ayilonguqulelo ikhethekileyo ngeyona ndlela ingqongqo yegama, njengoko iqhina kukudityaniswa kwezinto ezidityanisiweyo kunye ngendlela yokuncamathelisa. Ngale ndlela imisinga yeeddy eyenziwe ngexesha lokusetyenziswa kwemagnethi inokuncipha ngandlel’ ithile, iphucule kakhulu ukuthembeka kwemagnethi ngexesha lokusetyenziswa.
I-injection Molding - I-injection molding yindlela yokuvelisa iimilo kwiimveliso zoshishino. Iimveliso zidla ngokubunjwa kusetyenziswa ukubumba inaliti yerabha kunye nokubumba inaliti yeplastiki. Isitofu sokubumba sinokwahlulwa ngendlela yokubumba inaliti kunye nendlela yokuphosa ukufa. Ukusebenzisa ukubumba inaliti njengendlela yokuvelisa kunokubonelela ngamathuba amaninzi kwiimilo zemagnethi. Ngenxa yeepropathi zemagnethi ngokwazo, iimagnethi ze-sintered zihlala zilukhuni kwaye kunzima ukuvelisa iimilo ezithile. Indlela yokubumba inaliti ikholisa ukwenza iimilo ezininzi zibe nokwenzeka ngokubandakanya ezinye izinto.
I-Flexible Magnet- Umazibuthe oguquguqukayo ngumazibuthe onokugotywa kwaye ukhubazeke kwaye iimpawu zayo zemagneti zihlala zilungile. Ezi magnethi zihlala zenziwe ngezinto eziguquguqukayo, ezifana nerabha, i-polyurethane, njl., kwaye zixutywe nomgubo wemagneti ukuze zizenze zibe yimagnethi. Ngokungafaniyo noomazibuthe bemveli, iimagnethi ezibhetyebhetye zibhetyebhetye ngakumbi kwaye zithambile, ngoko ke zinokusikwa kwaye zigotywe ngokwemilo eyahlukeneyo njengoko kufuneka. Kananjalo zineempawu zokuncamathela ezingcono kwaye zingasetyenziselwa a
I-Solenoid: Isichasi semagnethi esisigxina yimagnethi yombane, enokuthiwa yimagnethi yethutyana. Olu hlobo lwemagnethi yikhoyili eyenza iluphu ngokusonga iingcingo kwisixhobo esingundoqo, esikwaziwa ngokuba yi-solenoid. Ngokugqithisa umbane kwi-solenoid, i-magnetic field esetyenziselwa ukwenza i-electromagnetize ivele. Intsimi yamagnetic enamandla kakhulu ivela ngaphakathi kwikhoyili, kwaye amandla entsimi ayanda kunye nenani leekhoyili kunye namandla akhoyo. I-Electromagnets ibhetyebhetye ngakumbi kwaye inokulungelelanisa indlela yemagnethi ngokwendlela yangoku, kwaye inokulungelelanisa amandla akhoyo njengoko kufuneka ukufezekisa amandla afunwayo.
