Pehea e hana ai kahi kaʻa AC asynchronous?

2024-06-14

HeAC asynchronous motorhe ʻano kaʻa kaʻa uila e hoʻohana ana i ka mana alternating current (AC). Kapa ʻia ʻo ia he "asynchronous" no ka mea ʻoi aku ka lohi o ka māmā ma mua o ka wikiwiki synchronous, ʻo ia ka wikiwiki o ke kahua magnetic i ka stator.


ʻElua mau ʻāpana ka AC asynchronous motor: ka stator a me ka rotor. ʻO ka stator ka ʻāpana paʻa o ka kaʻa i loaʻa i kahi ʻano wili a hoʻopili ʻia i ke kumu mana. ʻO ka rotor ka ʻāpana wili o ka kaʻa i hoʻopili ʻia i ka ukana, a ua hana ʻia ia me kahi ʻano o nā conductors i hoʻonohonoho ʻia i ke ʻano pōʻai.


Ke hoʻohana ʻia ka mana i nā wili stator, hoʻokumu ʻia kahi māla magnetic alternating. A laila, hoʻoulu kēia māla magnetic i kahi kahua electromagnetic i nā wili rotor, kahi e huli ai ka rotor. ʻO ka hoʻololi ʻana o ka rotor e hoʻohuli i kahi kumu i hoʻopili ʻia i ka rotor, a laila e hoʻokau i ka ukana.


ʻO ka wikiwiki o ka AC asynchronous motor ma muli o ke alapine o ka mana AC a me ka helu o nā pou i ka stator. Hoʻoholo ʻia ka helu o nā pou e ka helu o nā wili stator a me ke kūkulu ʻana o ka kaʻa. ʻOi aku ka nui o nā pou i loaʻa i ke kaʻa, ʻoi aku ka lohi o ka wikiwiki o ke kaʻa.


I ka hōʻuluʻulu ʻana, hana nā kaʻa AC asynchronous me ka hoʻohana ʻana i ka pilina ma waena o nā māla magnetic i ka stator a me ka rotor e hana i ka rotation. ʻOi aku ka lohi o ka mīkini ma mua o ka wikiwiki synchronous a hoʻoholo ʻia e ke alapine o ka mana AC a me ka helu o nā pou i ka stator.


Loaʻa i nā motika AC asynchronous kekahi mau pono, me:


Hoʻoikaika Kiʻekiʻe: He mea maikaʻi loa lākou a hiki ke hoʻololi i ka pākēneka kiʻekiʻe o ka ikehu uila a lākou e ʻai ai i ka ikehu mechanical.


Hoʻolālā maʻalahi: He ʻano maʻalahi a paʻa ko lākou e maʻalahi ai ka hana, hana a mālama.


Mālama Haʻahaʻa: He liʻiliʻi kā lākou mau ʻāpana mechanical, e hōʻemi ana iā lākou i nā hemahema mechanical a i ʻole nā ​​​​pilikia mālama.


Paʻa: He lōʻihi lākou a hiki ke hana ma kahi ākea o nā mahana a me nā kaiapuni.


Kumukūʻai haʻahaʻa: He haʻahaʻa lākou i ke kumukūʻai i hoʻohālikelike ʻia me nā ʻano ʻokoʻa ʻē aʻe.


ʻO ka holoʻokoʻa, ʻo AC asynchronous motors kahi hopena hilinaʻi a kūpono hoʻi no nā noi he nui. Hoʻohana nui ʻia lākou i nā pamu, nā mea pā, nā compressors, a me nā noi ʻoihana ʻē aʻe kahi e pono ai kahi kumu paʻa o ka mana rotating.
