(Demagnetization Curves bakeng sa N40UH Neodymium Magnet)
Limanete li ’nile tsa khahla batho ka makholo a lilemo, li bontša matla a hlollang ao ho bonahalang a ke ke a hlalosoa. Bohareng ba matla a makenete ho na le lekhalo la demagnetization, e leng mohopolo oa mantlha oa ho utloisisa litšobotsi tsa eona tsa makenete. Ka poso ena ea blog, re kena leetong la ho fokotsa sekhahla sa demagnetization, ho senola liphiri tsa kaho ea eona le bohlokoa ba eona lits'ebetsong tse fapaneng. Kahoo, ha re ikakhele ka setotsoana lefatšeng la makenete 'me re hlahlobe ketsahalo ena e khahlisang!
Demagnetization curve e phatlalalitsoe
Demagnetization curve, e tsejoang hape e le curve ea magnetization kapa hysteresis loop, e bonts'a boits'oaro ba ntho ea makenete ha e le tlas'a matla a khoheli a fetohang. E bonts'a kamano lipakeng tsa matla a matla a khoheli le sephetho sa induction ea makenete kapa sekhahla sa flux. Ka ho rera matla a matla a khoheli (H) holim'a x-axis le matla a khoheli a matla a khoheli (B) ho y-axis, li-curve tsa demagnetization li re lumella ho utloisisa le ho sekaseka mekhoa ea khoheli ea thepa.
Ho Utloisisa Boitšoaro ba Lintho Tsa Magnetic
Ka ho sheba li-curve tsa demagnetization, re ka tseba lintlha tsa bohlokoa tse hlalosang boitšoaro ba thepa libakeng tse fapaneng tsa makenete. A re hlahlobeng lintlha tse tharo tsa bohlokoa:
1. Saturation point: Qalong, lekhalo le thella ka matla ho fihlela le fihla moeling, moo ho se nang keketseho ea matla a matla a khoheli e tla ama matla a phallo. Ntlha ena e tšoaea ho tlala ha thepa. Lisebelisoa tse fapaneng li na le lintlha tse fapaneng tsa saturation, tse emelang bokhoni ba tsona ba ho lula li le matla ka tlas'a matla a khoheli a matla.
2. Coercivity: Ho tsoela pele ka lehlakoreng le leng, matla a khoheli a fokotseha, e leng se etsang hore ho fokotsehe ha matla a khoheli. Leha ho le joalo, ha thepa e ntse e boloka tekanyo e itseng ea magnetization, ho tla ba le ntlha eo mokokotlo o kopanang le x-axis. Marang-rang ana a emela matla a qobelloang, kapa matla a qobellang, a bontšang khanyetso ea thepa ho demagnetization. Lisebelisoa tse nang le khatello e phahameng li sebelisoa ho limakete tse sa feleng kapa lits'ebetso tse ling tse sa feleng tsa makenete.
3. Remanence: Ha matla a matla a khoheli a fihla ho zero, mothipa o kopana le axis ea y ho fana ka boima ba 'mele oa ho fola kapa ho lula. Paramethara ena e bontša tekanyo eo thepa e lulang e le matla a khoheli esita le ka mor'a hore matla a khoheli a ka ntle a tlosoe. Remanence e phahameng e bohlokoa bakeng sa lits'ebetso tse hlokang boits'oaro ba nako e telele ba makenete.
Kopo le Bohlokoa
Li-curve tsa demagnetization li fana ka temohisiso ea bohlokoa mabapi le khetho ea thepa le ntlafatso bakeng sa lits'ebetso tse fapaneng. Mehlala e meng ea bohlokoa ke ena:
1. Li-motor: Ho tseba moepa oa demagnetization ho thusa ho rala li-motor tse sebetsang hantle tse nang le lisebelisoa tse ntlafalitsoeng tsa makenete tse ka mamellang matla a khoheli a phahameng ntle le demagnetization.
2. Polokelo ea lintlha tsa Magnetic: Li-curve tsa demagnetization li thusa baenjiniere ho hlahisa mecha ea litaba ea ho rekota e nepahetseng ka matla a lekaneng bakeng sa polokelo ea data e tšepahalang le e tšoarellang.
3. Lisebelisoa tsa Motlakase: Ho rala li-inductor cores le li-transformer ho hloka hore ho nahanoe ka hloko li-curve tsa demagnetization ho lumellana le litlhoko tse khethehileng tsa motlakase le tsa mochini.
Qetello
Kena lefatšeng la limakete ka lense ea demagnetization curves, e senola ho rarahana ha boits'oaro ba matla a khoheli le ts'ebeliso ea bona. Ka ho sebelisa matla a mothinya ona, baenjiniere ba betla tsela bakeng sa tsoelo-pele e ncha ho pholletsa le mafapha a mangata a fapaneng, ho bopa maemo a theknoloji ea bokamoso. Kahoo nakong e tlang ha u kopana le makenete, nka nakoana ho utloisisa saense ka morao ho matla a eona a makenete le liphiri tse patiloeng ka mokhoa o bonolo oa demagnetization curve.
