No ke aha i kiʻekiʻe ai ka pono o nā motika magnet mau loa?

ʻO ka motika synchronous magnet mau loa ka mea nui i haku ʻia me nā ʻāpana stator, rotor a me nā hale. E like me nā motika AC maʻamau, ʻo ke kumu stator he ʻano laminated e hōʻemi i ka nalowale hao i hoʻokumu ʻia e ke au eddy a me ka hopena hysteresis i ka wā o ka hana motika; ʻo nā wili he ʻano symmetrical ʻekolu-phase maʻamau, akā ʻokoʻa loa ke koho ʻana o nā parameter. He ʻokoʻa ke ʻano o ka ʻāpana rotor, me ka rotor magnet mau loa me ka hale squirrel starter, a me ka rotor magnet mau loa i hoʻokomo ʻia a i ʻole i kau ʻia ma luna. Hiki ke hana ʻia ke kumu rotor me ke ʻano paʻa a i ʻole ke ʻano laminated. Ua lako ka rotor me nā mea magnet mau loa, i kapa ʻia he kila magnetic.

Ma lalo o ka hana maʻamau o kahi motika magnet mau loa, aia nā kahua magnetic rotor a me stator i kahi kūlana synchronous. ʻAʻohe au i hoʻokomo ʻia i loko o ka ʻāpana rotor, a no laila ʻaʻohe pohō keleawe rotor a i ʻole hysteresis a me nā pohō eddy current. ʻAʻohe pono e noʻonoʻo i ka pilikia hana wela i hoʻokumu ʻia e nā pohō rotor. Ma keʻano laulā, hoʻohana ʻia nā motika magnet mau loa e nā mea hoʻololi alapine i hoʻolaʻa ʻia, nona nā hana hoʻomaka palupalu. Eia kekahi, he mau motika synchronous nā motika magnet mau loa a he ʻano o nā motika synchronous hiki ke hoʻoponopono ʻia ka mana mana i ka waiwai i kuhikuhi ʻia ma o ka ikaika o ka hoʻonāukiuki. No laila, hiki ke hoʻolālā ʻia ka mana mana i ka waiwai i koi ʻia.
Mai ka manaʻo o ka hoʻomaka ʻana, ma muli o ke kūlana maoli kahi e hoʻomaka ai nā motika magnet mau loa e nā lako mana hoʻololi alapine a i ʻole nā ​​​​mea hoʻololi alapine e pili ana, he maʻalahi loa ke kaʻina hoʻomaka o nā motika magnet mau loa; e like me ka hoʻomaka ʻana o nā motika hoʻololi alapine, pale ia i nā hemahema hoʻomaka o nā motika asynchronous squirrel-cage maʻamau.

I ka hopena, hiki i ka pono a me ka mana o nā motika magnet mau loa ke piʻi i nā pae kiʻekiʻe loa. He maʻalahi loa ko lākou ʻano a ua kaulana loa lākou ma ka mākeke i nā makahiki he ʻumi i hala. Eia nō naʻe, ʻo ka hewa demagnetization kahi pilikia hiki ʻole ke pale ʻia no nā motika magnet mau loa. Ke nui loa ke au a i ʻole ke kiʻekiʻe loa ka mahana, e piʻi koke ka mahana o ka wili motika, e piʻi koke ke au, a e demagnetize koke ka magnet mau loa. I ka mana o nā motika magnet mau loa, ua hoʻonohonoho ʻia kahi mea pale overcurrent e pale aku i ka pilikia o ka wili stator o ke motika e puhi ʻia. Eia naʻe, ʻo kēia ke alakaʻi i ka demagnetization a me ka pani ʻana o nā lako.
