Zithini iiNeodymium Magnet Grades?

Ukucacisa iiNqanaba zeMagnet zeNeodymium: Isikhokelo esingesosobuGcisa

Iimpawu ze-alphanumeric ezibhalwe kwiimagnethi ze-neodymium—ezifana ne-N35, N42, N52, kunye ne-N42SH—ziyila isakhelo sokulebhelisha ukusebenza esithe ngqo. Icandelo leenombolo libonisa amandla okutsala amandla emagnethi, abizwa ngokusesikweni njengemveliso yamandla aphezulu (alinganiswa kwi-MGOe). Njengomgaqo jikelele, amaxabiso aphezulu eenombolo ahambelana namandla amakhulu emagnethi: imagnethi ye-N52 ibonisa amandla okubamba ngaphezulu kune-N42.

Izimamva zoonobumba zibonisa ukunyamezela ubushushu. Amanqanaba aqhelekileyo afana ne-N52 aqala ukonakala malunga nama-80°C, ngelixa iikhowudi ezifana ne-SH, UH, okanye i-EH zibonisa uzinzo lobushushu. I-N42SH igcina iipropati zayo zemagnethi kumaqondo obushushu afikelela kwi-150°C—ibalulekile kwiinjini zeemoto okanye kwizinto zokufudumeza zoshishino apho amaqondo obushushu enyuka rhoqo.

Kutheni Amandla Aphezulu Angasoloko Eyimpendulo

Kungokwemvelo ukucinga ukuba ibakala eliphezulu limele ukhetho olufanelekileyo, kodwa amava ahlala engqina okwahlukileyo.

Amanqanaba aphezulu ancama ukuqina ngenxa yamandla. Sihlala sidibana neemagnethi zesikwere ze-N52 eziqhekezayo ngexesha lokufakelwa okanye eziqhekekayo phantsi kokungcangcazela komgca wokuhlanganisa. Okwangoku, amanqanaba e-N35-N45 abonisa ukuqina okumangalisayo kwezi meko zinzima.

Icala lezemali nalo lifuna ukuqwalaselwa. Iimagnethi ezikumgangatho ophezulu zihlala zibiza ngaphezulu kwama-20-40% kunezinye iindlela eziphakathi. Nantsi indlela yokusebenza esiyisebenzisa rhoqo: imagnethi ye-N42 enkulu kancinci idla ngokuhambelana namandla okutsala eyunithi encinci ye-N52, inika ukusebenza okulinganayo ngexabiso eliphantsi kunye nobude obuphuculweyo.

Ungakulibali ukusebenza kobushushu. Iimagnethi ze-N52 eziqhelekileyo ziwohloka ngokukhawuleza xa zichatshazelwa zizixhobo zokuwelda, iindawo zenjini, okanye nokuba zikhanyiswe lilanga ngokuthe ngqo. Ukutyala imali kwiiklasi ezimelana nobushushu ezifana ne-N45SH okanye i-N48UH kwasekuqaleni kungqineka kungabizi kakhulu kunokutshintsha iiyunithi ezingasebenzisi umbane kamva.

Ukufanisa iiMagnets zeSquare Neodymium kwizicelo zokwenyani

Ijometri yomphezulu othe tyabaiimagnethi zesikwere ze-neodymiumkuqinisekisa ukusasazwa kwamandla okugqwesileyo, kodwa ukukhetha umgangatho ofanelekileyo kusabalulekile ukuze kuphumelele.

Izicelo zoMatshini wezoShishino
Izixhobo zemagnethi, iijigi, kunye neenkqubo zokuhambisa zisebenza kakuhle ngeegreyidi ze-N35-N45. Ezi zibonelela ngamandla okubamba aneleyo ngelixa zixhathisa uxinzelelo loomatshini kwiindawo zoshishino. Imagnethi yesikwere ye-25mm N35, umzekelo, idla ngokugcina ukusebenza okuthembekileyo apho ezinye iindlela ezibuthathaka zodidi oluphezulu zinokungaphumeleli.

Ukuphunyezwa kwe-Compact Electronics
Izixhobo ezixineneyo esithubeni ezifana neesensa, izithethi ezincinci, kunye netekhnoloji enxitywayo ziyazuza kwimithombo enamandla yemagnethi ye-N50-N52 grades. Ezi zenza iinjineli zikwazi ukufezekisa ukusebenza okufunekayo ngaphakathi kwemida encinci yendawo.

Iindawo ezishushu kakhulu
Usetyenziso olukufutshane neemoto, iinkqubo zokufudumeza, okanye izixhobo zeemoto zifuna amanqanaba akhethekileyo. Imagnethi yesikwere ye-N40SH igcina uzinzo kwi-150°C, apho iimagnethi eziqhelekileyo ziya konakala ngokukhawuleza.

Iiprojekthi zePrototyping kunye nezeSiko
Kwiisetingi zovavanyo kunye nezicelo ze-DIY, iiklasi ze-N35-N42 zibonelela ngokulinganisela okufanelekileyo kwamandla aneleyo, ukufikeleleka, kunye nokumelana nomonakalo ngexesha lokuphathwa rhoqo.

Izinto Ezibalulekileyo Eziqwalaselweyo Ekuphunyezweni

Nangona ukukhetha amanqaku kubaluleke kakhulu, ezi zinto zisebenzayo zichaphazela kakhulu ukusebenza kwehlabathi lokwenyani:

Iinkqubo zoKhuselo lomphezulu
I-Nickel plating inika ukhuseleko olwaneleyo kwiindawo ezilawulwayo zangaphakathi, kodwa i-epoxy coating ibalulekile kwiindawo ezimanzi okanye ezivezwe ngamakhemikhali. Idatha yethu yasentsimini ibonisa rhoqo iimagnethi ezifakwe i-epoxy ezihlala iminyaka emininzi ngaphandle, ngelixa i-nickel-plated equivalents zihlala zibonisa ukugqwala ngaphakathi kweenyanga.

Ukuchaneka kweMveliso
Ukuhambelana kobukhulu kuqinisekisa ukuhlanganiswa okufanelekileyo kwiindlela zokucwangcisa ezinemagnethi ezininzi. Sicebisa ukuqinisekisa ubungakanani besampulu ngezixhobo zokulinganisa ngokuchanekileyo ngaphambi kokuba uzibophelele kubungakanani bemveliso.

Ukuqinisekiswa kokusebenza
Uvavanyo lwamandla okutsalwa kwelebhu luhlala luhluka kwiziphumo zehlabathi lokwenyani. Soloko uvavanya iiprototypes phantsi kweemeko zokusebenza zokwenyani—sibone ungcoliseko lomphezulu olufana neoyile lunciphisa amandla asebenzayo ukuya kuthi ga kwi-50% kwezinye iimeko.

Ukujongana neenkxalabo ezisebenzayo

Ukwenziwa ngokwezifiso komthamo omncinci
Nangona amanqanaba apheleleyo enziwe ngokwezifiso edla ngokufuna izibophelelo zeeyunithi ezingaphezu kwama-2,000, uninzi lwabavelisi luhlangabezana neeprojekthi ezincinci ngokulungiswa okuqhelekileyo kwiimigangatho ezidumileyo ezifana ne-N35 okanye i-N52.

Uqoqosho lweBanga lobushushu
Iindidi ezimelana nobushushu zibonelela ngeprimiyamu yexabiso eliphakathi kwama-20-40% kuneeklasi eziqhelekileyo, kodwa olu tyalo-mali lubonakala lufanelekile xa kujongwa ezinye iindleko zokutshintsha iimagnethi ezingasebenziyo kwizicelo ezibalulekileyo.

Iingcamango Ezingalunganga Zokusebenza
I-N52 inika amandla aphezulu phantsi kweemeko ezifanelekileyo zelebhu kodwa ibeka emngciphekweni ukuqina kunye nozinzo lobushushu. Kwiimeko zobushushu obuphezulu, i-N50SH idla ngokubonelela ngokuthembeka okuhlala kuhleli nangona amandla eethiyori esezantsi kancinci.

Iinyani Zokuhlala Uqinile
Ubude bexesha abunyuki ngokwezinga—kwiindawo ezingcangcazela kakhulu, iimagnethi ezinkulu ze-N35 zihlala ixesha elide kunee-N52 equivalents ezibuthathaka.

Indlela yoKhetho oluCwangcisiweyo

Ukusetyenziswa ngempumelelo kwemagnethi kufuna ukulinganisela izinto ezininzi endaweni yokwandisa amandla. Cinga ngeemeko zokusingqongileyo, uxinzelelo loomatshini, imida yendawo, kunye nemida yohlahlo-lwabiwo mali kunye.

Soloko uqinisekisa ukhetho ngovavanyo olusebenzayo phantsi kweemeko zokusebenza zangempela. Sebenzisana nabavelisi ababonisa ukuqonda okunyanisekileyo kweemfuno zesicelo sakho endaweni yokucubungula nje iintengiselwano. Umthengisi osemgangathweni uya kucebisa ukuba ungachazi amanqanaba aqinileyo kakhulu—kwaye ngenxa yoko abuthathaka kakhulu—kusetyenziso olucetywayo.

Ukukhetha amanqaku ngononophelo, kunye namanyathelo okuqinisekisa apheleleyo, kuqinisekisa ukuba iimagnethi zesikwere ze-neodymium zibonelela ngokusebenza okuthembekileyo nokuhlala ixesha elide kuluhlu olubanzi lweemeko zokusetyenziswa kwemizi-mveliso kunye norhwebo.

Kubalulekile ukuvavanya iiprototypes phantsi kweemeko zokusebenza zokwenyani kunokuthembela kuphela kwiinkcukacha zedatha. Ukongeza, sebenzisana nomenzi obandakanyeka ngokunzulu kwiimfuno zeprojekthi yakho—hayi nje lowo ucubungula iiodolo. Umthengisi othembekileyo uya kunika isikhokelo xa ibakala elikhethiweyo liqinile ngokungeyomfuneko—kwaye ngenxa yoko libuthathaka kakhulu—kusetyenziso olucetywayo. Ngomgangatho ofanelekileyo nomsebenzi wesikolo omncinci, iimagnethi zakho zesikwere se-neodymium ziya kwenza umsebenzi wazo ngokuthembekileyo—imihla ngemihla.
