Halbach Array yog ib qho sib nqus sib nqus uas ua rau muaj qhov sib nqus siab siv cov hlau nplaum tas mus li, npaj nrog lub voj voog sib nqus rotating magnetic teb vector uas muaj cov nyhuv ntawm tsom thiab augmenting lub magnetic teb ntawm ib sab, thaum tshem tawm ntawm lwm yam. Halbach Arrays muaj peev xwm ua tau zoo heev thiab tsis sib xws flux densities yam tsis tas yuav tsum muaj lub zog hluav taws xob lossis cua txias, uas lub tshuab hluav taws xob xav tau.
Lub Halbach array yog ib qho tshwj xeeb ntawm cov hlau nplaum ruaj khov uas ua rau cov hlau nplaum sib nqus ntawm ib sab ntawm cov array muaj zog, thaum tshem tawm cov teb mus ze ze rau ntawm lwm sab. Qhov no txawv heev ntawm cov hlau nplaum nyob ib ncig ntawm ib qho hlau nplaum. Nrog ib tus hlau nplaum, koj muaj qhov sib npaug ntawm lub zog sib nqus ntawm ob sab ntawm cov hlau nplaum, raws li qhia hauv qab no:
Ib qho hlau nplaum yog qhia ntawm sab laug, nrog rau sab qaum teb ncej tig mus thoob plaws. Lub zog teb, qhia los ntawm cov xim nplai, muaj zog sib npaug ntawm sab saum toj thiab hauv qab ntawm cov hlau nplaum. Hauv qhov sib piv, Halbach array qhia ntawm txoj cai muaj thaj chaw muaj zog heev nyob rau sab saum toj, thiab thaj chaw tsis muaj zog nyob hauv qab. Cov hlau nplaum ib leeg tau pom ntawm no ua 5 lub voos xwmfab zoo li Halbach array, tab sis nrog tag nrho cov ncej qaum teb taw qhia. Magnetically, qhov no yog tib yam li ib lub hlau nplaum ntev.
Cov txiaj ntsig tau pib pom los ntawm John C. Mallinson hauv xyoo 1973, thiab cov qauv "ib leeg ib sab" tau piav qhia los ntawm nws raws li kev xav paub (IEEE daim ntawv txuas). Nyob rau xyoo 1980, tus kws kho mob Klaus Halbach nws tus kheej tau tsim lub Halbach array los tsom cov kab teeb, hluav taws xob thiab lasers.
Ntau yam ntawm cov cuab yeej siv niaj hnub no yog siv los ntawm Halbach array. Piv txwv li, Halbach cylinders yog lub tog raj kheej hlau nplaum uas muaj peev xwm ua kom muaj zog tab sis muaj cov hlau nplaum. Cov thooj voos kheej kheej no yog siv rau hauv cov khoom siv xws li brushless motors, magnetic couplings, thiab high field particle focusing cylinders. Txawm tias yooj yim lub tub yees hlau nplaum siv Halbach arrays-lawv muaj zog ntawm ib sab, tab sis tsis tshua lo rau ntawm sab nraud. Thaum koj pom cov hlau nplaum nrog cov hlau nplaum sib nqus uas tau nce rau ntawm ib sab thiab txo qis rau sab nraud, koj tab tom saib Halbach array hauv kev nqis tes ua.
Honsen Magnetics tau tsim cov hlau nplaum ruaj khov Halbach Arrays rau kev lag luam thiab kev siv rau lub sijhawm ntev. Peb tshwj xeeb hauv kev tsim qauv, engineering thiab kev tsim khoom ntawm ntau ntu, ncig thiab tawm (planar) Halbach arrays thiab Halbach-hom sib nqus sib nqus, muab ntau cov ncej configurations nrog high-field concentrations thiab high-uniformity.
