Magnet sreath Halbach<\/h1>\n

A bheil feum agad air raon magnetach l\u00e0idir air aon taobh agus faisg air neoni air an taobh eile? Tha fuasgladh ann\u2014gun u\u00e8irichean, d\u00ecreach maighstirean.<\/p>\n

Is e sreath Halbach r\u00e8iteachadh glic de mhaighstirean a neartaicheas an raon magnetach air aon aghaidh fhad \u2018s a tha e a\u2019 cuir \u00e0s dha air an taobh eile.<\/strong><\/p>\n

Cruinneachadh maighstirean sreath Halbach<\/p><\/div>\n

Cuir fios thugainn airson tuilleadh fiosrachaidh mu Magnet sreath Halbach<\/a><\/strong><\/span><\/p>\n

Bho motaran gu tr\u00e8anaichean maglev, tha an dealbhadh cumhachdach seo a\u2019 draibheadh \u00e0m ri teachd innleadaireachd magnetach.<\/p>\n

D\u00e8 a th\u2019 ann an sreath Halbach air a chleachdadh airson?<\/h2>\n

Tha maighstirean feumail\u2014ach d\u00e8 nam b\u2019 urrainn dhuinn an cumhachd aca a sti\u00f9ireadh ann an aon sti\u00f9ir d\u00ecreach?<\/p>\n

Tha sreath Halbach air a chleachdadh ann am motaran, siostaman leudachaidh magnetach, agus luathaichean gr\u00e0inean far a bheil raointean magnetach sti\u00f9irichte a\u2019 leasachadh coileanadh agus \u00e8ifeachdas.<\/strong><\/p>\n

Far a bheil sreathan Halbach a\u2019 seasamh a-mach<\/h3>\n

Tha sreathan Halbach a\u2019 cuimseachadh raointean magnetach ann an aon sti\u00f9ir. Tha seo na atharrachadh m\u00f2r airson tagraidhean a dh\u2019 fheumas raointean magnetach l\u00e0idir gun eadar-theachd no l\u00f9th air a chall. Seo mar a th\u00e8id an cur an s\u00e0s:<\/p>\n

1. Motaran Dealain<\/strong><\/h4>\n

Tha sreathan Halbach air an cleachdadh ann am motaran gun bruisean gus torque, \u00e8ifeachdas, agus d\u00f9mhlachd cumhachd a leasachadh. Tha iad a\u2019 lughdachadh call bho iarann c\u00f9il agus a\u2019 ceadachadh dealbhadh motair teann.<\/p>\n

2. Leudachadh Magnetach (Maglev)<\/strong><\/h4>\n

Bidh tr\u00e8anaichean maglev a\u2019 cleachdadh sreathan Halbach airson leudachadh seasmhach, gun tarraing. Tha an raon cuimsichte a\u2019 ceadachadh gluasad r\u00e8idh gun cheangal corporra.<\/p>\n

3. Luchd-astarachd Parcailean<\/strong><\/h4>\n

Tha sreathan Halbach a\u2019 cruthachadh raointean magnetach l\u00e0idir, aon-fhollaiseach ann an undulators synchrotron, a chuidicheas le bhith a\u2019 cromadh agus a\u2019 luathachadh gr\u00e0inean airson rannsachadh no \u00ecomhaighean.<\/p>\n

4. MRI agus Uidheam Meidigeach<\/strong><\/h4>\n

Bidh cuid de dhealbhadh MRI adhartach a\u2019 cleachdadh silindaran Halbach gus raointean a-staigh homogeneach a chruthachadh le eadar-theachd bhon taobh a-muigh cho beag \u2018s as urrainn.<\/p>\n\n\n\n\n\n\n\n\n

Anns na pr\u00f2iseactan agam fh\u00ecn, chunnaic mi dealbhadh Halbach a\u2019 lughdachadh cuideam an t-siostaim le 20% fhad \u2018s a bha an toradh magnetach air a chumail no air a mheudachadh. Is e sin buannachd mh\u00f2r airson innealan \u00e0rd-choileanadh.<\/p>\n

Cia mheud nas l\u00e0idire a tha sreath Halbach?<\/h2>\n

Tha fios againn gu bheil an raon d\u00f9inte, ach cia mheud nas cumhachdaiche a tha e?<\/p>\n

Faodaidh sreath Halbach raon magnetach a chruthachadh suas ri 1.4\u20132 tursan nas l\u00e0idire air an taobh obrach an coimeas ri r\u00e8iteachadh magnetan traidiseanta a\u2019 cleachdadh na stuthan aon an aon rud.<\/strong><\/p>\n

Carson a tha an raon a\u2019 f\u00e0s nas l\u00e0idire<\/h3>\n

Bidh r\u00e8iteachadh magnet traidiseanta a\u2019 leigeil sruth magnetach a-mach ann an iomadh sti\u00f9ir. Ach bidh sreath Halbach a\u2019 cuairteachadh suidheachadh gach magnet gus an l\u00f9th sin gu l\u00e8ir a sti\u00f9ireadh gu aon taobh d\u00f9inte.<\/p>\n

Mar a tha e ag obair:<\/h4>\n
    \n
  • Tha tuill a\u2019 chr\u00ecoch a tuath is a deas aig gach magnet air an r\u00e8iteachadh gus neart an raoin a neartachadh air aon taobh.<\/li>\n
  • Bidh na raointean an aghaidh a\u2019 cuir \u00e0s dha ch\u00e8ile air an taobh eile.<\/li>\n
  • An toradh: neart raon obrach air a neartachadh, raointean stray air an lughdachadh.<\/li>\n<\/ul>\n

    Eisimpleir:<\/h4>\n

    Smaoinich gu bheil thu a\u2019 cur sreath de cheithir magnetan:<\/p>\n

      \n
    • Ann an sreath \u00e0bhaisteach, bidh raointean a\u2019 leigeil a-mach os cionn is fo.<\/li>\n
    • Ann an r\u00e8iteachadh Halbach (cuairteachadh 0\u00b0, 90\u00b0, 180\u00b0, 270\u00b0), bidh raointean a\u2019 cuir \u00e0s fo agus a\u2019 cuimseachadh suas.<\/li>\n<\/ul>\n\n\n\n\n\n\n\n

      Rinn sinn rotor Halbach airson motair gun chridhe a choileanas 15% barrachd torque gach amp. Leig sin leis an neach-ceannach againn meud bataraidh a ghearradh agus \u00e8ifeachdas teasachaidh a leasachadh.<\/p>\n

      Co-dh\u00f9nadh<\/h2>\n

      Tha sreathan Halbach nan d\u00f2igh glic, chompact airson magnetachd a smachdachadh. Tha iad a\u2019 cruinneachadh neart far a bheil feum agus a\u2019 cur \u00e0s do sgudal\u2014f\u00ecor mhath airson motaran, leudachadh, agus teicne\u00f2las adhartach.<\/p>\n
