Nā Motors AC-Asynchronous Motors

ʻO AC asynchronous motor kahi ʻano mea huki uila e hoʻololi i ka ikehu uila i ka ikehu mechanical. Loaʻa ia i kahi stator, he rotor a me kahi ākea ea ma waena o lākou. Ma hope o ka wili ʻana o ka stator e alakaʻi i ka mana AC ʻekolu-phase, hoʻopuka ia i kahi māla magnetic rotating a ʻoki i ka rotor e loaʻa ai ka torque. ʻEkolu-phase AC asynchronous kaʻa ka maikaʻi o ka hoʻolālā maʻalahi, ka hana hilinaʻi, ke kumukūʻai kūʻai, ka mana overload ikaika a me ka hoʻohana maʻalahi, ka hoʻonohonoho ʻana a me ka mālama ʻana, a me nā mea ʻē aʻe. Hāʻawi mākou i kahi ākea o nā kaʻa no nā ʻoihana like ʻole e hoʻokō i nā pono o ka mea kūʻai aku, a hiki ke hilinaʻi ʻia ka maikaʻi o kā mākou mau kaʻa.

ʻO nā mea ʻona AC

ʻO ke kaʻa AC he ʻano kaʻa uila e hoʻohana ana i ka mana ʻokoʻa no ka mana. Hoʻohana ia me ka hoʻohana ʻana i ka electromagnetic induction, ʻo ia ke kumu e hoʻohana ai ia i ke au hou e hoʻokele i kāna rotor. ʻElua mau ʻāpana nui o kahi kaʻa AC: kahi stator i kū a me kahi rotor e hoʻololi. He ʻekolu ʻāpana a hoʻokahi paha kaʻa, e pili ana i ke ʻano o ka hana i manaʻo ʻia e hana.

ʻO ka motor Asynchronous kahi ʻano kaʻa AC e pili ana i ka pili ʻana o ka ea ea e hoʻololi ana i ke kahua magnetic a me ka rotor winding induction current e hana i ka electromagnetic torque a ʻike i ka hoʻololi ʻana i ka ikehu. ʻO ka motor Asynchronous ka maʻamau o nā huahana me nā ʻano kikoʻī ākea, a ʻo ia ka mea i hoʻohana nui ʻia ma waena o nā mea āpau. nā ʻaka uila me ka koi nui loa; i kēia manawa, ma kahi o 90% o nā mīkini i ka hoʻoili mana e hoʻohana ana i ka motika AC asynchronous, no laila, ʻoi aku ka nui o kāna hoʻohana mana ma mua o ka hapalua o ka huina uila.

ʻO nā mea ʻona AC

ʻO nā motika induction maʻamau he mau kaʻa asynchronous hoʻokahi-phase a me nā motika asynchronous ʻekolu-phase, ʻo ia ka ʻekolu-phase asynchronous motor ke kino nui o ka motor asynchronous. Hoʻohana maʻamau ka mīkini asynchronous hoʻokahi-phase i nā wahi i kūpono ʻole ai ka mana o ka mana ʻekolu, a ʻo ka hapa nui o lākou he miniature a me nā mīkini liʻiliʻi liʻiliʻi, i hoʻohana nui ʻia i nā mea hana hale, e like me nā uila uila, nā pahu hau, nā ea. nā mea hoʻomaʻemaʻe, nā mea hoʻomaʻemaʻe, a pēlā aku.

ʻO nā pono o AC Asynchronous Motors

  • ʻIke ʻia no kona hilinaʻi kiʻekiʻe a me ke ola lawelawe lōʻihi
  • Hiki ke hoʻohana pololei ʻia nā kaʻa a pau mai ka mains a i ʻole inverter
  • Nui loa, loaʻa i nā ʻano hoʻoluʻu like ʻole, nā papa pale a me nā hiʻohiʻona
  • He kūpono no nā kūlana kaiapuni corrosive a me nā noi pōʻino
  • ʻOi aku ka maikaʻi o ka kaʻa, hoʻoluʻu maikaʻi loa
  • Hoʻopaʻa ʻia nā kumukūʻai hana haʻahaʻa
  • ʻO ka ʻenehana terminal maʻalahi no ka laina hānai a me ka synergy kūpono o nā mea āpau
  • E hōʻoia i ka hana palekana a hilinaʻi o ka ʻōnaehana kaʻa holoʻokoʻa

Noi o AC Asynchronous Motors

Loaʻa i ka motor Asynchronous ka maikaʻi o ka hoʻolālā maʻalahi, ka hana maʻalahi, ka hoʻohana a me ka mālama ʻana, ka hana hilinaʻi a me ka liʻiliʻi liʻiliʻi a me ke kumu kūʻai haʻahaʻa. Eia kekahi, ʻoi aku ka maikaʻi o ka hana asynchronous a me nā hiʻohiʻona hana maikaʻi, mai ka loaʻa ʻole a hiki i ka piha piha piha kokoke i ka hana wikiwiki mau, hiki ke hoʻokō i nā koi hoʻouna o ka hapa nui o nā mīkini hana ʻoihana a me ka mahiʻai. Hoʻohana nui ʻia nā motika Asynchronous e hoʻokele i nā mea mīkini, nā paila, nā mea puhi, nā mea hoʻoheheʻe, nā mea hoʻokiʻekiʻe a me nā mea wiliwili, nā mīkini mining, nā mīkini ʻenehana māmā, nā mīkini ʻenehana a me nā ʻaoʻao ʻaoʻao a me ka hapa nui o nā ʻoihana a me nā mīkini hana mahiʻai.

Pehea ka hana ʻana o AC Motors?

ʻElua mau mea nui o ka motika AC - he rotor a me kahi stator. ʻO ka stator kahi mea paʻa i loaʻa i ʻeono mau pou magnetic kaʻawale, aʻo ka rotor e hoʻololi me ka hoʻololi ʻana o ka stator. I ka hoʻomaka ʻana o ka pōʻai, ʻo ka rotor a me ka stator nā polarities kūʻē, a i ka wā e huki ʻia ai nā pou ʻelua i kekahi i kekahi, e huli ka rotor.

ʻO ka motika AC he mea hana uila kūikawā e hilinaʻi ana i kahi alternator. Hoʻopuka ka mea hoʻololi i ke kuhikuhi ʻana i ka hoʻouka ʻana ma o ka hana ʻana i kahi kahua electromagnetic i ka wā e hele ai ka uila ma ke kumu wili o ka rotor. Hoʻololi ka rotor e pili ana i ka stator, a ʻo ka hopena EMF he ikaika e hoʻololi i ke kuhikuhi ma nā wahi i koho mua ʻia.

ʻO nā mea ʻona AC

ʻO ka stator ka ʻāpana paʻa o kahi kaʻa AC, a ua hana ʻia mai ʻelua pūʻulu o nā coils electromagnet ʻulaʻula. Piʻi a hāʻule ke au i loko o nā ʻōwili ma ke ʻano hawewe sine. Hoʻoulu kēia neʻe i kahi au uila i loko o ka rotor, kahi e hoʻohuli ai i ka rotor.

He ʻano maʻamau ka motika AC, akā aia kekahi mau ʻano like ʻole ma ke kumu kumu. Hoʻohana ʻia kahi kaʻa AC ma ke ala ʻokoʻa (AC). Hoʻohuli ka hāʻawi AC i ke kuhikuhi 50 manawa i kēlā me kēia kekona, a i ʻole Hz.

Kakini AC VS DC Motor

ʻO ke koho ma waena o kahi kaʻa AC a me kahi ʻIke DC pili nui i ka noi. No ka laʻana, ʻoi aku ka maikaʻi o nā kaʻa AC ma mua o nā kaʻa DC no ka mea hoʻohana lākou i nā electromagnets i ka stator, e hoʻopau i ka uila. Ma ka hoʻohālikelike ʻana, hoʻohana nā motor DC i nā magnet mau loa, ʻoi aku ka maikaʻi. Hoʻopilikia pū ʻia nā motika AC i ka paheʻe, ʻo ia ka ʻokoʻa ma waena o ka wikiwiki o ka rotor a me ka wikiwiki o ke kahua magnetic. He mea koʻikoʻi kēia no ka hana ʻana i ka torque, akā kōkua pū kekahi i ka nalowale o ka mana ma muli o ka wela.

ʻO kekahi pono ʻē aʻe o kahi kaʻa AC ʻo ia ka māmā a loaʻa ka mana wikiwiki. Hiki i kēia ke hoʻomaikaʻi i ka manawa huakaʻi a me ka maʻalahi. Eia kekahi, ʻoi aku ka haʻahaʻa o ka mīkini AC, a hiki ke hāʻawi aku i nā hoʻomaka wikiwiki. Eia naʻe, ʻaʻole pono ka hoʻololi ʻana mai DC a AC, a ua nalowale nā ​​pōmaikaʻi o ka hoʻemi ʻana i ke kaumaha ma ke kaʻina hana. Eia nō naʻe, ua hoʻolilo ka uila uila i ka motika AC i ʻoi aku ka hilinaʻi a ʻoi aku ka maʻalahi.

ʻO nā mea ʻona AC

ʻO nā ʻokoʻa nui ma waena o AC motor a me DC motor ka nui, ka hoʻolālā, ke kumukūʻai, ka mālama ʻana, a me ka hilinaʻi. ʻOi aku ka paʻakikī o nā motika AC ma mua o nā kaʻa DC, a paʻakikī loa kā lākou mau loina hana.

ʻO kekahi ʻokoʻa ʻē aʻe ma waena o nā ʻano ʻelua o nā kaʻa ka commutator. He commutator kahi kaʻa DC, kahi e maʻalahi ai ke hoʻokaʻawale mai kahi kaʻa AC. ʻO ka commutator kahi mea koʻikoʻi loa o kahi kaʻa DC. No laila, he mea nui e hoʻomaopopo i ke ʻano o ia mea a me kāna mau pono.
