A Halbach Array isimba remagineti rinogadzira yakakwira magineti ichishandisa magineti echigarire, yakarongwa nemhepo inotenderera yemagineti yemagetsi ine mhedzisiro yekutarisisa uye kuwedzera iyo magineti kune rimwe divi, ichidzima kune rimwe divi. Halbach Arrays inokwanisa kuwana yakanyanya kukwirira uye yunifomu flux densities pasina kudikanwa chero simba rekuisa kana kutonhora, izvo zvingadiwa ne electromagnet.
A Halbach array igadziriro yakakosha yemagineti echigarire anoita kuti magineti kune rimwe divi rerunyoro risimbe, uku ichidzima munda kusvika pedyo ne zero kune rimwe divi. Izvi zvakasiyana chaizvo nemagnetic field akatenderedza magineti imwe chete. Iine magineti imwe chete, une simba rakaenzana remagineti kune rimwe divi remagineti, sezvinoratidzwa pazasi:
Magineti imwe chete inoratidzwa kuruboshwe, nedanda rekuchamhembe rakatarisa kumusoro. Simba remunda, rinoratidzwa nechiyero chemavara, chakaenzana chakasimba pamusoro uye pasi pemagineti. Mukupesana, iyo Halbach array inoratidzwa kurudyi ine munda wakasimba kwazvo kumusoro, uye munda usina kusimba pazasi. Iyo magineti imwe chete inoratidzwa pano semakubhi mashanu senge Halbach array, asi nemapango ese ekuchamhembe akanongedza kumusoro. Magnetically, izvi zvakafanana negineti refu refu.
Mhedzisiro yacho yakatanga kuwanikwa naJohn C. Mallinson muna 1973, uye izvi "imwe-sided flux" zvimiro zvakatanga kutsanangurwa naye sekuda kuziva (IEEE paper link). Mumakore ekuma1980, nyanzvi yefizikisi Klaus Halbach yakazvimiririra yakagadzira Halbach array kuti itarise matanda, maerekitironi nemalaser.
Zvizhinji zvinoumba tekinoroji yemazuva ano zvinofambiswa neHalbach array. Semuyenzaniso, masilinda eHalbach masilinda ane magineti anokwanisa kugadzira akasimba asi aine magineti. Aya masilinda anoshandiswa mumidziyo senge brushless mota, magineti couplings, uye yakakwira munda particle inotarisisa masilinda. Kunyangwe magineti efiriji ari nyore anoshandisa Halbach arrays-akasimba kune rumwe rutivi, asi haatombonamira zvachose kune rimwe divi. Paunoona magineti ine simba remagineti rinowedzerwa kune rimwe divi uye richidzikira kune rimwe divi, unenge uri kuona iyo Halbach array ichiita.
Honsen Magnetics yakagadzira magineti echigarire Halbach Arrays yemaindasitiri uye tekinoroji maapplication kwenguva yakareba. Isu tine hunyanzvi mukugadzira dhizaini, huinjiniya uye kugadzirwa kweakawanda-segmented, denderedzwa uye linear (planar) Halbach arrays uye Halbach-mhando yemagineti maassemblies, achipa akawanda pole magadzirirwo ane yakakwira-munda wakanyanya uye yakakwirira-yakafanana.
