No ke aha i ʻoi aku ka maikaʻi o nā mīkini magnet paʻa?

ʻO ka motor synchronous magnet paʻa ka mea nui o ka stator, rotor a me nā mea hale. E like me nā kaʻa AC maʻamau, ʻo ka stator core he hale laminated e hōʻemi i ka poho hao ma muli o ka eddy current a me nā hopena hysteresis i ka wā o ka hana kaʻa; ʻO nā wiliwili hoʻi he ʻekolu-phase symmetrical structures, akā ʻokoʻa ke koho koho. He ʻano ʻano like ʻole ka ʻāpana rotor, me nā rotors magnet mau me ka hoʻomaka ʻana i nā hīnaʻi squirrel, a i kūkulu ʻia a i ʻole i kau ʻia ma luna o nā rotors magnet mau loa. Hiki ke hana ʻia ke kumu rotor i mea paʻa a laminated paha. Hoʻolako ʻia ka rotor me nā mea magnet mau loa, ka mea i kapa ʻia he kila magnet.

Ma lalo o ka hana maʻamau o ka mīkini magnet mau loa, aia ka rotor a me ka stator magnetic field i kahi synchronous state, ʻaʻohe mea i hoʻokomo ʻia i loko o ka ʻāpana rotor, ʻaʻohe poho keleawe rotor, hysteresis, a me ka nalowale o kēia manawa, ʻaʻohe pono. e noʻonoʻo i ka pilikia o ka poho rotor a me ka hana wela. ʻO ka mea maʻamau, hoʻohana ʻia ka mīkini magnet mau e kahi mea hoʻololi alapine kūikawā, a loaʻa maoli kahi hana hoʻomaka palupalu. Eia kekahi, ʻo ka motor magnet paʻa he motor synchronous, nona nā hiʻohiʻona o ka hoʻoponopono ʻana i ka mea mana o ka mīkini synchronous ma o ka ikaika o ka excitation, no laila hiki ke hoʻolālā ʻia ka mana mana i kahi waiwai i kuhikuhi ʻia.

Mai ka hiʻohiʻona o ka hoʻomaka ʻana, ma muli o ka hoʻomaka ʻana o ka mīkini paʻa paʻa e ka mana o ka mana alapine a i ʻole ke kākoʻo ʻana i ke alapine converter, maʻalahi ka ʻike ʻana i ke kaʻina hoʻomaka o ka mīkini magnet mau loa; e like me ka hoʻomaka ʻana o ka mīkini alapine ʻokoʻa, e pale aku i nā hemahema hoʻomaka o ka mīkini asynchronous ʻano cage-type maʻamau.

I ka pōkole, hiki ke piʻi kiʻekiʻe loa ka hana a me ka mana o nā mīkini magnet mau loa, a maʻalahi loa ke ʻano. Ua wela loa ka mākeke i nā makahiki he ʻumi i hala.

Eia nō naʻe, he pilikia hiki ʻole ke pale ʻia ka demagnetization no nā kaʻa magnet mau loa. Ke kiʻekiʻe loa ke au a i ʻole ke kiʻekiʻe o ka wela, e piʻi koke ka mahana o nā wili kaʻa, e piʻi nui ke au, a e nalowale nā ​​magnet mau loa i ko lākou magnetism. Ma ka mana kaʻa kaʻa paʻa mau, ua hoʻonohonoho ʻia kahi mea pale overcurrent e pale aku i ka pilikia o ka puhi ʻana o ka stator stator e puhi ʻia, akā ʻaʻole hiki ke pale ʻia ka hopena o ka magnetization a me ka pani ʻana i nā mea hana.

Ke hoʻohālikelike ʻia me nā kaʻa ʻē aʻe, ʻaʻole kaulana loa ka hoʻohana ʻana i nā motor magnet mau loa i ka mākeke. Aia kekahi mau wahi makapō ʻenehana i ʻike ʻole ʻia no nā mea hana kaʻa a me nā mea hoʻohana, ʻoi loa i ka wā e pili ana i ka hoʻohālikelike ʻana me nā mea hoʻololi pinepine, e alakaʻi pinepine ai i ka hoʻolālā ʻAʻole kūlike ka waiwai me ka ʻikepili hoʻokolohua a pono e hōʻoia pinepine ʻia.
