ʻO ka motika air conditioner kekahi o nā mea nui o ka ea.Me ka ʻole o ke kaʻa, nalowale ka manaʻo o ka ea.

ʻO nā kaʻa hoʻoheheʻe ea ka nui o nā mea hoʻoheheʻe, nā ʻenekini pā (axial fans a me nā cross-flow fans), a me ka hoʻolele ʻana i nā lau hāʻawi ea (nā kaʻa holo wāwae a me nā kaʻa hui pū)

ʻO ka ʻenekini asynchronous ʻāpana hoʻokahi

ʻO nā compressors hoʻokahi-phase no nā ea ea he ʻelua wili, ʻo ia ka wili hoʻomaka a me ka wili e holo ana (main winding), a me ʻekolu mau hopena, ʻo ia ka terminal maʻamau, ka pahu hoʻomaka a me ka pahu holo, e alakaʻi mau ʻia e ka hana capacitor a hoʻokō i ka hoʻomalu wikiwiki mau.

I ke kaʻina hana o ka hoʻomaka ʻana i ke kaʻa i ka hana maʻamau, pili mau ke kaʻapuni wiliwili kōkua me kahi capacitor i ka moʻo, i hiki i ka mea uila ke holo maikaʻi i ka hana, kiʻekiʻe kiʻekiʻe a me ka mana kumu, a hana pono.

ʻEkolu mau ʻāpana asynchronous motor

Ua like kona ʻano me ke ʻano o ke kaʻa hoʻokahi.ʻO ka ʻokoʻa, ʻo ka stator o kahi kaʻa kaʻa ʻekolu-phase i haku ʻia me ʻekolu pūʻulu o nā wiliwili like ʻole.Hoʻokomo ʻia kēia mau wiliwili ʻekolu i loko o nā ʻauwaʻa stator core a hoʻopaʻapaʻa ʻia e ka 120 ° ʻeke uila i ka māhele spatial.

Hiki ke hoʻohui ʻia nā wili ʻekolu ma ke ʻano Y a i ʻole ke ʻano △.Ke hoʻokomo ʻia nā ʻano like ʻole ʻekolu i loko o nā wili stator (ʻo ia hoʻi, ʻokoʻa nā ʻano ʻekolu o nā ʻano i ka 120 ° ma ke ʻano o ka manawa a me ka pae), ʻo ka ea ea ma waena o nā rotors e hoʻohua ai i kahi māla magnetic rotating. e hoʻoulu i ka torque electromagnetic ma muli o ka induction electromagnetic.

ʻO ka mīkini asynchronous ʻekolu-phase he hana maʻalahi a me ka hana maikaʻi loa.ʻOi aku ka kiʻekiʻe o ka torque, ka hoʻokō a me ka mana mana ma mua o ka mea o ka mīkini asynchronous hoʻokahi.No laila, ea conditioners me ka kiʻekiʻe mana, e like me ka cabinet air conditioner compressors, ka hapanui hoʻohana 'ekolu-phase asynchronous motors.

ʻO nā loina o nā kaʻa i hoʻohana ʻia i nā ea ea ʻē aʻe

1. Ke kaʻa stepper

ʻO ke kaʻa stepper he mea hoʻokō e hoʻololi i nā hōʻailona pulse uila i ka neʻe laina a i ʻole ka angular displacement, ʻo ia hoʻi, ke kau ʻia kahi hōʻailona pulse i ka kaʻa, neʻe ke kaʻa i hoʻokahi kapuaʻi.

ʻO ka rotor he cylindrical two-pole permanent magnet rotor i hana ʻia me nā magnet mau loa.ʻO ka pōʻai o loko o ka stator a me ka pōʻai o waho o ka rotor he ʻano eccentricity, no laila ʻaʻole kūlike ka ea, a ʻo ka ea ka liʻiliʻi loa, ʻo ia hoʻi, ʻo ke kūʻē magnetic ka mea liʻiliʻi loa.

Hoʻonohonoho ʻia kahi wili koʻikoʻi i loko o ka armature stator, a hoʻohui ʻia nā hōʻailona pulse uila i nā ʻaoʻao ʻelua o ka wili e kahi lako mana kūikawā.I ka wā ʻaʻole i hoʻoikaika ʻia ka wili ʻana o ka stator, aia kahi puʻupuʻu magnetic i hana ʻia e ka rotor magnet mau loa i ke kaapuni magnetic o ke kaʻa.

E hele ana kēia kahe i ke koʻi o nā pou rotor i ke kūlana ma ke kaapuni magnetic kahi e liʻiliʻi ai ka makemake.

Ke hoʻohui ka mana mana i kahi pulse i ka wili kaʻa, ua hoʻohuli ʻia nā polarities o nā pole magnetic ʻelua o ka stator a me nā pou magnetic ʻelua o ka rotor, a ʻo ka holo ʻana o ka rotor ma kahi o 180° counterclockwise ma ke kuhikuhi o ka pua n a hiki i ka ʻokoʻa nā pou kuʻekuʻe o ka stator a me nā pou ʻē aʻe o ka rotor.

2. Mekini paʻa synchronous motor

ʻO ka micro-motor i hoʻohana ʻia i loko o ka mea hoʻoheheʻe ea puka grill swing blade mea he mākēneki mau ʻo synchronous claw-pole self-starting synchronous motor.

ʻO ka uila hoʻokele kaʻa he ~ 220V/50Hz, a ʻo kona stator he pahu kīʻaha kīʻaha, he annular single-phase coil a me nā ʻāpana pole;ʻO ka rotor he apo ferrite me ka coercivity kiʻekiʻe.

Hoʻokaʻawale ʻia nā lāʻau māuʻu ma ka pōʻai, a ʻo ka helu o nā pole maiuu (magnetic pole pairs) e hoʻoholo ʻia e ka wikiwiki synchronous i koi ʻia.ʻO ka mīkini koʻi ka nui o nā pou mākū, haʻahaʻa haʻahaʻa, torque nui, mana liʻiliʻi liʻiliʻi, hana maʻalahi a ʻaʻohe hoʻokele paʻa.Hoʻokomo pinepine ʻia ka master switch ma ka papa hoʻomalu o ka ea.ʻO ia ka hoʻololi mana e hoʻopili ai i ka mea hoʻoheheʻe, peʻa a me nā mea hoʻokō ʻē aʻe, a me ka mea koho koho e hoʻololi i ke kūlana holo o ka ea.
