Ke kahua noi nui loa onā mākēneki mau loa honuaʻo ia nā ʻenekini paʻa mau, i ʻike nui ʻia ʻo nā kaʻa.
ʻO nā kaʻa ma ke ʻano ākea ka mea e hoʻololi i ka ikehu uila i ka ikehu mechanical a me nā mea hana e hoʻololi i ka ikehu mechanical i ka ikehu uila.Ke hilinaʻi nei nā ʻano kaʻa ʻelua i ke kumu o ka induction electromagnetic a i ʻole ka electromagnetic ikaika e like me kā lākou kumu kumu.ʻO ke kahua magnetic ea-gap kahi mea e pono ai no ka hana o ka kaʻa.ʻO ke kaʻa e hoʻohua ai i ke kahua mākēneki ea ma o ka hauʻoli, ua kapa ʻia ʻo ia he ʻenekini induction, aʻo kahi kaʻa e hoʻohua ai i ke kahua mākēneki ea-gap ma o nā magnet mau loa, ua kapa ʻia ʻo ia he motor magnet mau loa.
I loko o kahi kaʻa magnet mau loa, hoʻokumu ʻia ke kahua mākēneki ea-gap e nā magnet mau loa me ka ʻole o ka pono o ka mana uila a i ʻole nā wili hou.No laila, ʻo nā pōmaikaʻi nui loa o nā kaʻa magnet mau loa ma luna o nā kaʻa induction he kiʻekiʻe kiʻekiʻe, mālama i ka ikehu, ka nui compact, a me ke ʻano maʻalahi.No laila, hoʻohana nui ʻia nā mīkini magnet paʻa i nā ʻano ʻokoʻa liʻiliʻi a me nā mīkini micro.Hōʻike ka kiʻi ma lalo nei i kahi ʻano hana maʻalahi o kahi kaʻa DC magnet mau loa.ʻElua mau mākēneki paʻa e hoʻopuka i kahi māla magnetic i waenakonu o ka wili.Ke hoʻoikaika ʻia ka coil, loaʻa iā ia kahi mana electromagnetic (e like me ka lula hema) a huli.Ua kapa ʻia ka ʻāpana wili i loko o kahi kaʻa uila he rotor, a ʻo ka ʻāpana kū i kapa ʻia ʻo ka stator.E like me ka mea i ʻike ʻia mai ke kiʻi, aia nā magnet mau i ka stator, aʻo nā coils no ka rotor.
No nā kaʻa kaʻa, inā ʻo ka stator ka mea hoʻokele mau, ua hui pū ʻia ma ka hoʻonohonoho #2, kahi i hoʻopili ʻia ai nā magnet i ka hale kaʻa.Inā ʻo ka rotor ka mākēneki mau, ua hui pū ʻia ia ma ka hoʻonohonoho #1, me nā magnet i hoʻopili ʻia i ke kumu rotor.ʻO kahi ʻē aʻe, pili ka hoʻonohonoho #3, #4, #5, a me #6 i ka hoʻokomo ʻana i nā mea magnet i loko o ke kumu rotor, e like me ka mea i hōʻike ʻia ma ke kiʻikuhi.
No nā kaʻa laina laina, ʻo nā magnet mau loa ke ʻano o nā ʻāpana a me nā paralelograms.Hoʻohui ʻia, hoʻohana nā motor linear cylindrical i nā magneti annular axially magnetized.
ʻO nā Magnets ma Permanent Magnet Motor nā hiʻohiʻona penei:
1. ʻAʻole paʻakikī loa ke ʻano (koe naʻe kekahi mau motika micro, e like me nā motika VCM), ka nui ma nā ʻano ʻāpana ʻehā, trapezoidal, peʻahi, a me nā ʻano berena.ʻO ka mea kūikawā, i ka hoʻohaʻahaʻa ʻana i nā kumukūʻai hoʻolālā kaʻa, nui ka poʻe e hoʻohana i nā magnet square embedded.
2. He mea maʻalahi ka magnetization, ka nui o ka magnetization hoʻokahi-pole, a ma hope o ka hui ʻana, hana ia i kahi kaapuni magnetic multi-pole.Inā he apo piha, e like me ke apo neodymium hao boron a i ʻole ke apo wela, hoʻohana pinepine ia i ka magnetization radiation multi-pole.
3. ʻO ke kumu nui o nā koi ʻenehana i loko o ke kūpaʻa wela kiʻekiʻe, ke kūlike o ka flux magnetic, a me ka adaptability.Pono nā mākēneki rotor i hoʻopaʻa ʻia i ka ʻili i nā waiwai hoʻopili maikaʻi, ʻoi aku ka nui o nā koi o nā mīkini kaʻa laina no ka paʻakai paʻakai, ʻoi aku ka paʻakikī o nā mea hoʻoheheʻe makani makani no ka pāpaʻi paʻakai, a ʻo nā mea hoʻokele kaʻa kaʻa e pono ai ke kūpaʻa kiʻekiʻe.
4. Hoʻohana ʻia nā huahana ikehu magnetic kiʻekiʻe, waena, a me ka haʻahaʻa, akā ʻo ka coercivity ka hapa nui ma waena a kiʻekiʻe.I kēia manawa, ʻo nā māka hoʻohana maʻamau no nā kaʻa kaʻa kaʻa kaʻa ka nui o nā huahana ikehu kiʻekiʻe a me ka coercivity kiʻekiʻe, e like me 45UH, 48UH, 50UH, 42EH, 45EH, a me nā mea ʻē aʻe, a he mea nui ka ʻenehana diffusion.
5. Ua hoʻohana nui ʻia nā magnet laminated segmented adhesive i nā kahua kaʻa kaʻa wela kiʻekiʻe.ʻO ke kumu o ka hoʻomaikaʻi ʻana i ka insulation segmentation o nā magnet a hōʻemi i nā poho eddy i ka wā o ka hana kaʻa, a hiki i kekahi mau magnet ke hoʻohui i ka uhi epoxy ma ka ʻili e hoʻonui i kā lākou insulation.
Nā mea hoʻāʻo koʻikoʻi no nā magnet motor:
1. Pa'a wela ki'eki'e: Pono kekahi po'e kū'ai e ana i ka pohō mākēneki hāmama, a'o nā mea'ē a'e e pono ana e ana i ka palaho māneki semi-open-circuit.I ka wā o ka hana kaʻa, pono nā mea magnet e kū i nā wela kiʻekiʻe a me ka hoʻohuli ʻana i nā māla magnetic.No laila, pono ka hoʻāʻo ʻana a me ka nānā ʻana i ka palaho magnetic huahana a me nā pihi demagnetization kiʻekiʻe o ka mea kumu.
2. Mākēneki flux kūlike: ʻO ke kumu o nā māla magnetic no nā rotors kaʻa a i ʻole stators, inā he like ʻole i ka flux magnetic, hiki ke hoʻoulu i ka haʻalulu kaʻa, a me ka hoʻemi ʻana i ka mana, a pili i ka hana holoʻokoʻa o ka mīkini.No laila, loaʻa i nā mea hoʻokele kaʻa nā koi no ke kūlike o ka flux magnetic, kekahi i loko o 5%, kekahi i loko o 3%, a i ʻole 2%.Pono e noʻonoʻo ʻia nā mea e pili ana i ke kūlike o ka flux magnetic, e like me ke kūlike o ke koena magnetism, hoʻomanawanui, a me ka uhi chamfer.
3. Hiki ke hoʻololi: ʻO nā magnet i kau ʻia ma luna o ke ʻano nui i ke ʻano tile.ʻO nā ʻano hoʻāʻo ʻelua-dimensional maʻamau no nā kihi a me nā radii he nui nā hewa a paʻakikī paha ke hoʻāʻo.Ma ia mau hihia, pono e noʻonoʻo ʻia ka hoʻololi ʻana.No nā magnet i hoʻonohonoho pono ʻia, pono e hoʻomalu ʻia nā ʻāpana kumulative.No nā magnet me nā puʻu dovetail, pono e noʻonoʻo ʻia ka paʻa o ka hui.ʻOi aku ka maikaʻi o ka hana ʻana i nā mea paʻa maʻamau e like me ke ʻano o ka hui ʻana o ka mea hoʻohana e hoʻāʻo ai i ka hoʻololi ʻana o nā magnet.
