Halbach Array Magnetic System

Halbach Array Magnetic System

ʻO Halbach array kahi hoʻolālā magnet, kahi hoʻolālā kūpono i ka ʻenekinia. ʻO ka pahuhopu ka hoʻoulu ʻana i ka māla ikaika loa me ka helu liʻiliʻi o nā magnet. I ka makahiki 1979, i ka wā i alakaʻi ai ʻo Klaus Halbach, he kanaka ʻAmelika, i nā hoʻokolohua electron acceleration, ua ʻike ʻo ia i kēia ʻano hana hoʻokalakupua paʻa paʻa, hoʻomaikaʻi mālie i kēia hale, a hoʻokumu i ka mea i kapa ʻia ʻo "Halbach".

He aha nā Halbach Array Magnets

ʻO ka Halbach Array kahi ʻano magnetic e hoʻohua ai i kahi māla magnetic kiʻekiʻe me ka hoʻohana ʻana i nā magnet mau loa, i hoʻonohonoho ʻia me kahi vector spatially rotating magnetic field nona ka hopena o ka nānā ʻana a me ka hoʻonui ʻana i ke kahua magnetic ma kekahi ʻaoʻao, ʻoiai e hoʻopau ana ma kekahi ʻaoʻao. Hiki i nā Halbach Arrays ke hoʻokō i nā density flux kiʻekiʻe loa a me ka ʻole e koi ʻia i ka hoʻokomo mana a i ʻole ka hoʻoluʻu, kahi e pono ai kahi electromagnet.

ʻO kahi hui Halbach kahi hoʻonohonoho kūikawā o nā magnet mau loa e hoʻoikaika ai i ke kahua magnetic ma kekahi ʻaoʻao o ka ʻaoʻao, ʻoiai e hoʻopau ana i ke kahua a kokoke i ka zero ma kekahi ʻaoʻao. He ʻokoʻa loa kēia mai ke kahua magnetic a puni hoʻokahi magnet. Me ka mākēneki hoʻokahi, loaʻa iā ʻoe kahi mākēneki ikaika like ma kēlā ʻaoʻao kēia ʻaoʻao o ka magnet, e like me ka hōʻike ʻana ma lalo nei.

Hōʻike ʻia kahi magnet hoʻokahi ma ka hema, me ka kia ʻākau e kū pono ana i luna. ʻO ka ikaika o ke kahua, i hōʻike ʻia e ka pālākiō kala, ua like ka ikaika ma luna a me lalo o ka magnet. ʻO ka hoʻohālikelike ʻana, ʻo ka hui Halbach i hōʻike ʻia ma ka ʻākau he kahua ikaika loa ma luna, a he kahua nāwaliwali loa ma lalo. Hōʻike ʻia ka magnet hoʻokahi ma ʻaneʻi ma ke ʻano he 5 cubes e like me ka hui Halbach, akā me nā pole ʻākau āpau e kuhikuhi ana i luna. Ma keʻano magnetika, ua like kēia me ka magnet lōʻihi hoʻokahi.

Ua ʻike mua ʻia ka hopena e John C. Mallinson i ka makahiki 1973, a ua wehewehe mua ʻia kēia mau hale "hoʻokahi ʻaoʻao" e ia ma ke ʻano he ʻike (IEEE pepa loulou). I ka makahiki 1980, ua hoʻokumu kaʻawale ʻo Klaus Halbach i ka array Halbach e kālele i nā kaola, electrons a me nā lasers.

Halbach Arrays a me ka ʻenehana hou

Nui nā ʻāpana o ka ʻenehana hou i hoʻohana ʻia e ka hui Halbach. No ka laʻana, ʻo Halbach cylinders he mau pahu magnetized hiki ke hana i kahi māla ikaika akā paʻa. Hoʻohana ʻia kēia mau cylinders i nā hāmeʻa e like me nā kaʻa brushless, nā hoʻohui magnetic, a me nā cylinders e nānā ana i ke kahua kiʻekiʻe. ʻO nā mea hoʻoheheʻe maʻalahi hoʻi e hoʻohana i nā arrays Halbach - ikaika lākou ma kekahi ʻaoʻao, akā ʻaʻole paʻa loa ma kēlā ʻaoʻao. Ke ʻike ʻoe i kahi magnet me kahi mākena i hoʻonui ʻia ma kekahi ʻaoʻao a hoʻemi ʻia ma kēlā ʻaoʻao, ke nānā nei ʻoe i ka hana Halbach.

Ua hana ʻo Honsen Magnetics iā Halbach Arrays mau loa no nā noi ʻenehana a me nā ʻenehana no ka manawa lōʻihi. Hoʻomaʻamaʻa mākou i ka hoʻolālā ʻenehana, ʻenekinia a me ka hana ʻana o nā huila Halbach multi-segmented, circular a linear (planar) a me Halbach-type magnetic assemblies, e hāʻawi ana i nā hoʻonohonoho pole he nui me nā kiʻekiʻe kiʻekiʻe a me nā kūlike kiʻekiʻe.
