I-Halbach Array Magnetic System

I-Halbach Array Magnetic System

I-Halbach array iyisakhiwo sikazibuthe, okuyisakhiwo esicishe sibe esikahle kwezobunjiniyela. Umgomo uwukukhiqiza inkambu kazibuthe enamandla kakhulu ngenani elincane lamazibuthe. Ngo-1979, lapho uKlaus Halbach, isazi saseMelika, enza izivivinyo zokusheshisa i-electron, wathola lesi sakhiwo esikhethekile sikazibuthe, kancane kancane sathuthukisa lesi sakhiwo, futhi ekugcineni sakha okuthiwa "i-Halbach" uzibuthe.

Yiziphi i-Halbach Array Magnets

I-Halbach Array iyinhlangano kazibuthe ekhiqiza inkambu kazibuthe ephezulu esebenzisa omagnethi baphakade, ehlelwe ngevector yamagnetic ezungeza indawo enomphumela wokugxilisa nokwandisa inkambu kazibuthe ngakolunye uhlangothi, kuyilapho iyikhansela ngakolunye. I-Halbach Arrays iyakwazi ukuzuza ukuminyana okuguquguqukayo okuphezulu kakhulu nokufanayo ngaphandle kwesidingo sokufaka amandla noma ukupholisa, okungadingwa i-electromagnetic.

I-Halbach array iwuhlelo olukhethekile lomazibuthe ongunaphakade elenza inkambu kazibuthe ohlangothini olulodwa lwamalungu afanayo ibe namandla, kuyilapho ikhansela inkambu isondele kuqanda ngakolunye uhlangothi. Lokhu kuhluke kakhulu endaweni kazibuthe ezungeze uzibuthe oyedwa. Ngozibuthe oyedwa, unamandla alinganayo kazibuthe nhlangothi zombili zikazibuthe, njengoba kuboniswe ngezansi:

Uzibuthe oyedwa uboniswa kwesokunxele, isigxobo esisenyakatho sibheke phezulu yonke indawo. Amandla enkundla, aboniswa isikali sombala, aqine ngokulinganayo phezulu nangaphansi kukazibuthe. Ngokuphambene, i-Halbach array eboniswe kwesokudla inenkambu eqine kakhulu phezulu, kanye nenkambu ebuthaka kancane phansi. Umazibuthe oyedwa uboniswa lapha njengama-cubes angu-5 afana ne-Halbach array, kodwa zonke izigxobo ezisenyakatho zibheke phezulu. Ngozibuthe, lokhu kuyafana nozibuthe owodwa omude.

neze

Umphumela waqale watholwa ngu-John C. Mallinson ngo-1973, futhi lezi zakhiwo "zohlangothi olulodwa lwe-flux" ekuqaleni zachazwa nguye njengelukuluku (isixhumanisi sephepha le-IEEE). Ngawo-1980, isazi sefiziksi u-Klaus Halbach sasungula ngokuzimela i-Halbach array ukuze kugxiliswe imishayo yezinhlayiyana, ama-electron nama-lasers.

I-Halbach Arrays kanye Nobuchwepheshe Banamuhla

Izingxenye eziningi zobuchwepheshe besimanje zinikwa amandla yi-Halbach array. Isibonelo, amasilinda e-Halbach angamasilinda azibuthe akwazi ukukhiqiza inkambu kazibuthe enamandla kodwa equkethe. Lawa masilinda asetshenziswa kumadivayisi anjengama-brushless motors, ama-coupling kazibuthe, namasilinda agxile ezinhlayiyeni eziphezulu. Ngisho nozibuthe besiqandisi abalula basebenzisa ama-Halbach array—baqinile ohlangothini olulodwa, kodwa abanamathele nhlobo ngakolunye uhlangothi. Uma ubona uzibuthe onensimu kazibuthe eyandiswa ngakolunye uhlangothi futhi yehla ngakolunye uhlangothi, ubheka uhlelo lwe-Halbach lusebenza.

I-Honsen Magnetics ikhiqize uzibuthe ongapheli i-Halbach Arrays yezinhlelo zokusebenza zezimboni nezobuchwepheshe isikhathi eside. Sisebenza ngokukhethekile ekwakhiweni kobuchwepheshe, ubunjiniyela kanye nokukhiqizwa kwama-Halbach arrays anezigaba eziningi, ayindilinga kanye nomugqa (planar) kanye nohlobo lukazibuthe lwe-Halbach, sihlinzeka ngokucushwa kwezigxobo eziningi ezinokugxila kwenkundla ephezulu kanye nokufana okuphezulu.
