He aha ka Air Coil Inductor?
Ka hoomaopopo ana i na Kumu
ʻO nā inductors air coil, i ʻike ʻia hoʻi he ea-core inductors, he mau mea uila passive e mālama i ka ikehu i loko o kahi māla magnetic ke kahe ka uila ma o lākou. ʻAʻole like me nā mea hoʻokomo kuʻuna e hoʻohana ana i kahi kumu magnetic (e like me ka hao a i ʻole ka ferrite), hilinaʻi wale nā mea hoʻokomo i ka ea i ka lewa i loko o ko lākou ʻano uea wili. Hoʻopau kēia hoʻolālā i nā poho koʻikoʻi, e hoʻolilo iā lākou i mea kūpono no nā noi alapine kiʻekiʻe kahi koʻikoʻi ka pono a me ka liʻiliʻi.
ʻO nā hiʻohiʻona nui o nā inductors air coil:
·ʻAʻohe kumu magnetic: Hoemi i ka lilo ikehu a pale aku i na pilikia saturation.
·Kiʻekiʻe Q kumu: Hāʻawi i ka hana maikaʻi loa i nā kaapuni resonant.
·Haʻahaʻa inductance waiwai: Hoʻohana maʻamau i nā noi e koi ana i ka inductance haʻahaʻa.
Aia ma lalo iho ka hoʻohālikelike o nā mea hoʻohuihui air coil me nā inductors kuʻuna:
| Hiʻona | Ea Coil Inductor | Kuʻuna Inductor |
| Mea Kumu | Ea | Hao, Ferrite, etc. |
| Pohō i ka ikehu | liʻiliʻi | Kiʻekiʻe ma muli o ka poho kumu |
| Laulā pinepine | ʻO ke alapine kiʻekiʻe | Haʻahaʻa i waena o ka pinepine |
| Laulā Inductance | Haʻahaʻa a haʻahaʻa | Laulā laula |
ʻO ka hoʻomaopopo ʻana i kēia mau kumu e kōkua i ke koho ʻana i ka inductor kūpono no kāu papahana.
Pehea ka hana ʻana o nā Inductors Air Coil
Hoʻohana ʻia nā inductors air coil ma ke kumu o ka induction electromagnetic. Ke hele ka uwila i ka uea wili, hana ia i ke kahua magnetic a puni ka wili. No ka mea, ʻaʻohe kumu magnetic, ua hilinaʻi loa ka māla magnetic i ka helu o nā huli i loko o ka coil, ka geometry o ka coil, a me ke kahe e kahe ana ma loko.
Hoʻoholo ʻia ka inductance (L) o kahi inductor coil ea e ke kumu:
[ L = \frac{N^2 \cdot \mu_0 \cdot A}{l} ]
Ma hea:
·(N) = Ka helu o nā huli i loko o ka wili
·( \mu_0 ) = Ka hikiwawe o ka hakahaka kaʻawale (mau)
·(A) = ʻāpana keʻa o ka wili
·(l) = Ka lōʻihi o ka wili
Hōʻike kēia ʻano kumu i ka hopena o ka hoʻolālā kino o ka coil i kāna hana. No ka laʻana, e hoʻonui i ka helu o nā huli a i ʻole ke anawaena o ka coil e hoʻonui i ka inductance, aʻo ka coil lōʻihi e hoʻemi ia.
ʻOi aku ka maikaʻi o nā inductors air coil i nā kaapuni kiʻekiʻe no ka mea e pale aku lākou i ka hysteresis a me nā poho eddy e pili ana me nā cores magnetic. ʻO kēia ka mea i koho maikaʻi ʻia ma RF (radio frequency) a me nā ʻōnaehana kamaʻilio uila.

ʻO ka waiwai inductance o ka air coil inductor he mea koʻikoʻi e pili pono ana i kāna hana i kāu papahana. Ana ʻia i loko o nā henries (H), hoʻoholo ka inductance i ka maikaʻi o ka hiki ʻana i ka inductor ke mālama i ka ikehu i loko o kahi māla magnetic. No nā noi e like me nā kaapuni RF, nā kānana, a i ʻole nā pūnaewele hoʻokani, ke koho ʻana i ka waiwai inductance kūpono e hōʻoia i ka hana maikaʻi loa.
Ke koho ʻana i kahi inductor air coil, e noʻonoʻo i kēia:
·Laulā pinepine: Ua kūpono nā waiwai inductance kiʻekiʻe no nā noi haʻahaʻa haʻahaʻa, ʻoiai ʻoi aku ka maikaʻi o nā waiwai haʻahaʻa no nā kaapuni kiʻekiʻe.

5. Pehea wau e hōʻoia ai i ka launa pū ʻana ma waena o nā inductors coil air a me nā ʻāpana ʻē aʻe o kaʻu kaapuni?
ʻO ka hōʻoia ʻana i ka hoʻohālikelike ma waena o nā inductors air coil a me nā mea ʻē aʻe he mea koʻikoʻi no ka hana kaapuni maikaʻi loa. ʻO nā mea nui e noʻonoʻo ai:
·Hoʻohālikelike Impedance: E hōʻoia i ka hoʻopili ʻana o ka impedance o ka inductor me nā mea ʻē aʻe e pale i ka noʻonoʻo ʻana a i ʻole ka attenuation.
·Hana wela: E nānā i ka pae wela o ka hana a me nā waiwai hoʻoheheʻe wela, ʻoi loa no nā noi kiʻekiʻe.
·Hoʻohui kino: E hōʻoia i nā ana a me nā koho kau e hoʻopaʻa pono i ka inductor i loko o ka wahi i loaʻa ma kāu PCB a i ʻole chassis.
·Hōʻailona Pono: E noʻonoʻo i ka hopena o ka maikaʻi o ka hōʻailona, e like me ka walaʻau a i ʻole ka hoʻokaʻawale ʻana, ma o ka hoʻāʻo ʻana i ka inductor ma kahi kaapuni prototype.
