1, AC asynchronous motor

ʻO ka AC asynchronous motor ka mea alakaʻi i ka mana uila AC, ka mea i hoʻohana nui ʻia i nā pā uila, nā pahu hau, nā mīkini holoi, nā ea, nā mea maloʻo lauoho, nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe, nā puʻupuʻu ākea, nā mea holoi kīʻaha, nā mīkini humuhumu uila, nā mīkini hana meaʻai a me nā mea pono hale ʻē aʻe. a me nā mea uila like ʻole a me nā mea uila liʻiliʻi.

Ua hoʻokaʻawale ʻia ka motika AC asynchronous i ka motika induction a me ka motika commutator AC.Hoʻokaʻawale ʻia ka kaʻa induction i hoʻokahi-phase asynchronous motor, AC / DC motor a me repulsion motor.

ʻOi aku ka wikiwiki o ka moto (wikiwiki rotor) ma mua o ka wikiwiki o ke kahua magnetic rotating, no laila ua kapa ʻia ʻo ia ka motor asynchronous.Ua like ia me ka induction motor.S = (ns-n) / NS.ʻO S ka helu paheʻe,

ʻO NS ka māmā māmā a ʻo N ka māmā holo rotor.

Kumukānāwai kumu:

1. Ke hoʻopili ʻia ka motika asynchronous ʻekolu-phase i ka mana AC ʻekolu-phase, e kahe ana ka wili stator ʻekolu-phase ma o ka ikaika magnetomotive ʻekolu-phase (stator rotating magnetomotive force) i hana ʻia e ka ʻekolu-phase symmetrical current a hoʻohua. he māhina māneʻe kaʻapuni.

2. Aia ka neʻe ʻoki ʻoki pili i ke kahua mākēneki me ka mea hoʻokele rotor.E like me ke kumu o ka electromagnetic induction, hoʻopuka ka conductor rotor i ka ikaika electromotive induced a me ka manawa i hoʻokomo ʻia.

3. E like me ke kānāwai o ka mana electromagnetic, ua hoʻopili ʻia ka conductor rotor e lawe nei i kēia manawa e ka mana electromagnetic i loko o ke kahua magnetic e hana i ka torque electromagnetic a hoʻokele i ka rotor e hoʻololi.Ke loaʻa kahi haʻahaʻa mechanical ma ke kumu kaʻa, hoʻopuka ia i ka ikehu mechanical i waho.

ʻO ka motika Asynchronous kahi ʻano kaʻa AC, a ʻaʻole mau ka ratio o ka wikiwiki ma lalo o ka hoʻouka ʻana i ka alapine o ka mana mana pili.Hoʻololi pū me ka nui o ka ukana.ʻOi aku ka nui o ka hoʻouka ʻana, ʻoi aku ka haʻahaʻa o ka wikiwiki rotor.Hoʻokomo ʻia ka kaʻa Asynchronous i ka induction motor, ʻelua hānai ʻia ka mīkini induction a me ka AC commutator motor.ʻO ka motor induction ka mea hoʻohana nui loa.Hiki ke kapa ʻia ka motika asynchronous me ka ʻole o ka hoʻomaopopo ʻana a me ka huikau.

Hoʻopili ʻia ka wili stator o ka mīkini asynchronous maʻamau i ka mana AC, a ʻaʻole pono e hoʻopili ʻia ka wili rotor i nā kumu mana ʻē aʻe.No laila, loaʻa iā ia nā pōmaikaʻi o ka hoʻolālā maʻalahi, ka hana maʻalahi, ka hoʻohana a me ka mālama ʻana, ka hana hilinaʻi, ka haʻahaʻa haʻahaʻa a me ke kumu kūʻai haʻahaʻa.Loaʻa i ka mīkini Asynchronous ka hana kiʻekiʻe a me nā ʻano hana maikaʻi.Ke holo nei ia me ka wikiwiki mau mai ka ukana ʻole i ka ukana piha, hiki ke hoʻokō i nā koi hoʻouna o ka hapa nui o nā mīkini hana ʻoihana a me ka mahiʻai.He mea maʻalahi hoʻi nā motika Asynchronous e hana i nā ʻano pale like ʻole e hoʻokō i nā pono o nā kūlana kaiapuni.I ka holo ʻana o ka mīkini asynchronous, pono e hoʻomoʻi ʻia ka mana hoʻoulu reactive mai ka pahu mana e hōʻemi i ka mana o ka mana mana.No laila, hoʻohana pinepine ʻia nā motika synchronous e hoʻokele i ka mana kiʻekiʻe a me ka wikiwiki haʻahaʻa e like me nā wili pōleʻa a me nā compressors.Ma muli o ka wikiwiki o ka kaʻa asynchronous he pilina paheʻe me ka wikiwiki o ka māla magnetic, ʻilihune kāna hana hoʻoponopono wikiwiki (koe wale ka AC commutator motor).ʻOi aku ka maikaʻi a me ka maʻalahi o ka mīkini DC no ka mīkini kaʻa, ka wili wili, ka mīkini mīkini nui, ka paʻi ʻana a me ke kala a me nā mīkini hana pepa e koi ana i kahi ākea ākea a maʻalahi.Eia nō naʻe, me ka hoʻomohala ʻana o nā mea uila uila kiʻekiʻe a me ka ʻōnaehana hoʻoponopono wikiwiki AC, ua hoʻohālikelike ʻia ka hana hoʻoponopono wikiwiki a me ka hoʻokele waiwai o ka motor asynchronous kūpono no ka hoʻoponopono wikiwiki ākea me ka DC motor.
