ʻIkepili Pōmaikaʻi Paʻa o ka Hoʻololi ʻana i nā Motors Asynchronous me nā Motors Magnet Synchronous Motors.
Hoʻomaka mākou mai nā hiʻohiʻona o ka motor synchronous magnet mau loa, i hui pū ʻia me ka noi kūpono e wehewehe i nā pono piha o ka hoʻolaha ʻana i ka motor synchronous magnet mau loa.
ʻO ka motika synchronous e pili ana i ka motor asynchronous, nā mea maikaʻi o ke kumu mana kiʻekiʻe, kiʻekiʻe kiʻekiʻe, hiki ke ana ʻia nā ʻāpana rotor, ka nui o ka ea stator-rotor, ka hana mana maikaʻi, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hoʻolālā maʻalahi, kiʻekiʻe torque / inertia ratio, etc. ., I loko o ka aila, kemika 'oihana, malamalama textile, mining, CNC mīkini mea paahana, robots a me ka 'ē aʻe mahinaʻai ua increasingly hoʻohana 'ia, a me ka kiʻekiʻe-mana (kiʻekiʻe wikiwiki, kiʻekiʻe torque), kiʻekiʻe hana a me ka Miniaturization.
ʻO ka mīkini paʻa paʻa synchronous me kahi stator a me kahi rotor. Ua like ka stator me ke kaʻa asynchronous a loaʻa nā wili ʻekolu-phase a me kahi kumu stator. Ua like ka stator me ke kaʻa asynchronous, nona ʻekolu wili a me ka stator core. Hoʻolako ʻia ka rotor me nā magnet mau loa i hoʻopaʻa ʻia (magnetized), hiki ke hoʻokumu i kahi kahua magnetic i ka lewa a puni me ka ʻole o ka ikehu o waho, e hoʻomaʻamaʻa i ke ʻano o ka mīkini a mālama i ka ikehu.
ʻO nā pōmaikaʻi koʻikoʻi o ka motor synchronous magnet mau loa
(1) No ka mea, ua hana ʻia ka rotor me nā magnet mau loa, kiʻekiʻe ke kiʻekiʻe o ka flux magnetic a ʻaʻohe mea e pono ai ka hoʻoulu ʻana, pēlā e hoʻopau ai i ka nalowale o ka excitation. Ke hoʻohālikelike ʻia me ka motika asynchronous, hoʻemi ʻo ia i ka hau o ka ʻaoʻao stator wili a me ke keleawe a me ka hao o ka ʻaoʻao rotor, a hoʻemi nui i ka manawa reactive. Ma muli o ka hoʻonohonoho ʻana o ka stator a me nā hiki rotor, ʻaʻohe poho hao kumu i loko o ka rotor core, no laila ʻoi aku ka kiʻekiʻe o ka pono (e pili ana i ka mana hana) a me ka mana (e pili ana i ka mana reactive) kaʻa ʻaʻole like ʻole. Hoʻolālā maʻamau nā ʻenekini magnet synchronous e loaʻa i ke kumu mana kiʻekiʻe a me ka maikaʻi a hiki i ka hana haʻahaʻa māmā.
(2) Loaʻa nā ʻano mīkini paʻakiki paʻa i nā mīkini hoʻopaʻapaʻa magnet paʻa a me ke kūpaʻa ikaika ʻana i nā pilikia torque kaʻa ma muli o nā loli ukana. Hiki ke hana ʻia ke kumu rotor o kahi kaʻa kaʻa synchronous magnet paʻa i kahi ʻano hollow e hōʻemi i ka inertia rotor, a ʻoi aku ka wikiwiki o ka hoʻomaka a me ka hoʻomaha ʻana ma mua o nā kaʻa asynchronous. ʻO ke kiʻekiʻe torque / inertia ratio e hoʻolilo i nā motika synchronous magnet mau i kūpono no ka hana ma lalo o nā kūlana pane wikiwiki ma mua o nā kaʻa asynchronous.
(3) Hoʻemi nui ʻia ka nui o nā kaʻa kaʻa synchronous magnet paʻa i ka hoʻohālikelike ʻia me nā motika asynchronous, a ua hoʻemi ʻia ko lākou kaumaha. ʻOi aku ka nui o ka mana o nā kaʻa hoʻokalakupua mau loa me nā kūlana hoʻoheheʻe wela like a me nā mea insulation ʻoi aku ma mua o ʻelua mau manawa o nā kaʻa asynchronous ʻekolu.
(4) Ua maʻalahi loa ka hoʻolālā rotor, maʻalahi e mālama, a hoʻomaikaʻi i ka paʻa o ka hana.
(5) Ma muli o ka mana kiʻekiʻe e koi ʻia no ka hoʻolālā ʻana o nā motika asynchronous ʻekolu mau manawa, pono e mālama i ka lewa ma waena o ka stator a me ka rotor liʻiliʻi loa. I ka manawa like, he mea koʻikoʻi ka like ʻole o ka lewa ea no ka hana palekana a me ka leo haʻalulu o ka kaʻa. No laila, he koʻikoʻi koʻikoʻi nā kaʻa asynchronous no ke ʻano a me ke kūlana hoʻomanawanui o nā ʻāpana a me ka concentricity hui, a he liʻiliʻi liʻiliʻi o ke kūʻokoʻa no ke koho ʻana i ka ʻae ʻana. Hoʻohana pinepine nā motika asynchronous nui i nā bearings i lubricated e ka ʻauʻau aila, pono e hoʻohui i ka aila lubricating i loko o nā hola hana i kuhikuhi ʻia. ʻO ka leaka ʻaila a i ʻole ka hoʻopiha piha ʻana i ka keʻena aila hiki ke hoʻolalelale i ka hāʻule ʻana. I ka mālama ʻana i nā kaʻa asynchronous ʻekolu-phase, e lawe ana i nā moʻolelo mālama no ka hapa nui. Eia kekahi, ma muli o ka loaʻa ʻana o ka manawa i hoʻokomo ʻia i loko o ka rotor o nā kaʻa asynchronous ʻekolu, ʻo ka pilikia o ka hoʻoheheʻe uila o nā bearings i hopohopo nui i nā mea noiʻi i nā makahiki i hala.
(6) ʻAʻohe pilikia like ʻole nā motor synchronous magnet mau. ʻO nā pilikia pili i hoʻokumu ʻia e ka ea nui o nā kaʻa kaʻa synchronous magnet mau loa a me ka liʻiliʻi o ka ea ea o nā kaʻa asynchronous ma luna aʻe ʻaʻole i ʻike ʻia ma nā motika synchronous. I ka manawa like, hoʻohana nā bearings o nā mīkini paʻa magnet synchronous i nā bearings lubricated grease me nā uhi lepo. Hoʻopaʻa ʻia nā bearings me ka nui kūpono o ka momona lubricating kiʻekiʻe ma ka hale hana, hiki ke mālama ʻole ʻia no ke ola.
Epilogue
Mai ka hiʻohiʻona o nā pōmaikaʻi hoʻokele waiwai, kūpono nā kaʻa kaʻa synchronous mau loa no ka hoʻomaka kaumaha a me nā hiʻohiʻona hana māmā. ʻO ka paipai ʻana i ka hoʻohana ʻana i nā kaʻa kaʻa synchronous magnet mau loaʻa nā pōmaikaʻi waiwai a me ka pilikanaka, a he koʻikoʻi nui ia no ka mālama ʻana i ka ikehu a me ka hōʻemi ʻana i ka hoʻokuʻu. Ma ke ʻano o ka hilinaʻi a me ka paʻa, loaʻa nā pono waiwai nui nā motor synchronous magnet mau loa. ʻO ke koho ʻana i nā kaʻa kaʻa kaʻa hoʻokahi manawa hoʻokahi a me ke kaʻina hana pōmaikaʻi lōʻihi.
Ma hope o 16 mau makahiki o ka ʻenehana ʻenehana, ʻo Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co., Ltd ka mana R&D no ka piha piha o nā mīkini magnet mau loa, e uhi ana i nā ʻoihana like ʻole e like me ke kila, sima, a me nā mine lanahu, a hiki ke hoʻokō i nā pono o nā kūlana hana a me nā mea hana like ʻole. Ke hoʻohālikelike ʻia me nā kaʻa asynchronous o ka kikoʻī like, ʻoi aku ka maikaʻi o nā huahana o ka hui, ʻoi aku ka nui o ka hana hoʻokele waiwai, a me nā hopena hoʻōla ikaika. Ke kakali nei mākou i nā ʻoihana hou aʻe e hoʻohana ana i nā motor magnet mau loa i ka hiki ke hōʻemi i ka ʻai a hoʻonui i ka hana!
