Nā ʻano o ka Inductance Coils

Nā Inductors Air-Core

ʻO nā inductors air-core kahi ʻano kumu o ka inductance coil i ʻike ʻia e ka nele o kahi kumu magnetic. Akā, hilinaʻi wale lākou i ka lewa i loko o ka coil e hoʻomaʻamaʻa i ka flux magnetic. Hoʻohana nui ʻia kēia mau inductors i nā noi kiʻekiʻe ma muli o ko lākou haʻahaʻa haʻahaʻa haʻahaʻa a me ka liʻiliʻi liʻiliʻi i nā pā electromagnetic.

ʻO kekahi o nā pōmaikaʻi koʻikoʻi o nā inductors air-core ko lākou linearity, ʻo ia hoʻi ke kūpaʻa nei kā lākou inductance ma kahi ākea o nā alapine. ʻO kēia ka mea kūpono iā lākou no nā kaapuni lekiō (RF), nā noi hoʻokani, a me ke kānana hōʻailona. Eia nō naʻe, loaʻa iā lākou nā waiwai inductance haʻahaʻa i hoʻohālikelike ʻia i nā inductors kumu, hiki ke kaupalena i kā lākou hoʻohana ʻana i nā noi haʻahaʻa haʻahaʻa.

Aia ma lalo iho kahi hoʻohālikelike o nā inductors air-core me nā ʻano ʻē aʻe:

Hoʻohana pinepine ʻia nā inductors air-core i nā hiʻohiʻona kahi e hōʻemi ai i ka nalowale o ka ikehu a me ka mālama pono ʻana i ka hōʻailona he mea koʻikoʻi. ʻO kā lākou maʻalahi a me ka hilinaʻi e hoʻolilo iā lākou i mea koʻikoʻi i ka uila uila hou.

Mea Inductors-Core

Hoʻohana nā mea hoʻoheheʻe hao-core i kahi kumu magnetic i hana ʻia me ka hao a i ʻole ke kila e hoʻonui ai i kā lākou inductance a me ka hiki ke mālama i ka ikehu. ʻO ka hele ʻana o ke kumu nui e hoʻonui nui i ka nui o ka flux magnetic, e ʻae ana i kēia mau inductors e hoʻokō i nā koina inductance kiʻekiʻe ke hoʻohālikelike ʻia i nā hoʻolālā air-core.

Hoʻohana maʻamau ʻia kēia mau inductors i nā noi haʻahaʻa haʻahaʻa a me waena, e like me nā lako mana, nā transformers, a me nā kaʻa uila. Hoʻomaikaʻi ke kumu hao i ka maikaʻi ma ka noʻonoʻo ʻana i ke kahua magnetic, akā hoʻolauna pū kekahi i nā poho kumu ma muli o ka hysteresis a me nā au eddy. ʻAʻole kūpono kēia iā lākou no nā noi alapine kiʻekiʻe kahi e lilo ai ka ikehu i mea hopohopo.

ʻO nā hiʻohiʻona koʻikoʻi o nā inductors iron-core:

• Kiʻekiʻe Inductance:Kūpono no nā noi e koi ana i ka mālama ʻana i ka ikehu nui.
• ʻO ke kūkulu paʻa:He kūpono no nā kaiapuni mana kiʻekiʻe.
• Ka palena alapine:He kūpono no nā alapine ma lalo o 1 MHz.

ʻOiai ko lākou mau palena i nā hiʻohiʻona kiʻekiʻe, ʻo nā inductors iron-core he mea nui loa i nā ʻoihana e koi ana i ka hoʻokele ikehu hilinaʻi a maikaʻi.

ʻO Ferrite-Core Inductors

Hōʻike nā inductors ferrite-core i kahi kumu i hana ʻia me ka ferrite, kahi mea seramika me nā waiwai magnetic. He mea maikaʻi loa kēia mau cores i ka hōʻemi ʻana i nā poho eddy i kēia manawa, e hana ana i nā inductors ferrite-core kūpono no nā noi waena a kiʻekiʻe. Hoʻohana nui ʻia lākou i ka hoʻopau ʻana i ka electromagnetic interference (EMI), kānana hōʻailona, ​​a me ka hoʻololi ʻana i nā lako mana.

Hāʻawi nā kumu Ferrite i kahi kaulike ma waena o ka inductance a me ka hana pinepine. Hāʻawi lākou i ka inductance kiʻekiʻe ma mua o nā hoʻolālā air-core me ka mālama ʻana i nā poho haʻahaʻa i hoʻohālikelike ʻia i nā inductors iron-core ma nā alapine kiʻekiʻe. Hoʻohui ʻia, loaʻa nā mea ferrite i nā haku mele like ʻole, e ʻae ana i nā ʻenekini e hoʻohālikelike i ka hana o ka inductor i nā noi kikoʻī.

Aia ma lalo kahi hōʻuluʻulu o nā hiʻohiʻona ferrite-core inductor:

Manaʻo nui ʻia nā inductors ferrite-core no ko lākou versatility a me ka pono i ka uila uila hou, e hana ana iā lākou i koho kaulana no nā ʻenekinia ma Naheng Electronics a ma waho.

Hoʻohana maʻamau o Inductance Coils

Ma na Kaapuni Elele

ʻO nā coils inductance nā mea koʻikoʻi i nā kaʻa uila, kahi i hoʻohana mua ʻia ai e mālama i ka ikehu i loko o kahi māla magnetic a hoʻoponopono i ke kahe o kēia manawa. Loaʻa iā lākou ma nā kānana, nā oscillators, a me nā kaʻa kaʻa kaʻa, kahi i ko lākou hiki ke pale i nā hōʻailona kiʻekiʻe ʻoiai e ʻae ana i nā hōʻailona haʻahaʻa e hele i mea waiwai nui. No ka laʻana, ma nā kaapuni lekiō (RF), kōkua nā coils inductance e hoʻokaʻawale a hoʻokani i nā alapine kikoʻī, e hōʻoia i ka hoʻouna ʻana a me ka hoʻokipa ʻana.

Aia ma lalo iho kahi hoʻohālikelike o nā noi coil inductance i nā kaʻa uila:

Ke koho ʻana i nā coils inductance no nā kaapuni uila, pono e noʻonoʻo ʻia nā mea e like me ka inductance value, quality factor (Q-factor), a me ka pinepine resonant. Hāʻawi ʻo Naheng Electronics i kahi ʻano o nā coils kiʻekiʻe i hoʻolālā ʻia e hoʻokō i kēia mau koi, e hōʻoiaʻiʻo ana i ka hana hilinaʻi i nā hoʻolālā kaapuni like ʻole.

I nā lako mana a me nā mea hoʻololi

He koʻikoʻi ko Inductance coils i nā lako mana a me nā mea hoʻololi, kahi e hoʻohana ʻia ai lākou e hoʻokele i nā pae voltage, hoʻemi i ka nalowale o ka ikehu, a hoʻomaikaʻi i ka pono. I loko o nā lako mana hoʻololi (SMPS), ua hoʻohui ʻia nā coils i ka hoʻololi ʻana o AC i DC ma o ka hoʻomaʻamaʻa ʻana i nā fluctuations voltage a me ka mālama ʻana i ka ikehu i ka wā o ka hoʻololi ʻana. Pēlā nō, i nā mea hoʻololi, hiki i nā coils inductance ke hoʻololi i ka ikehu uila ma waena o nā kaʻa ma o ka induction electromagnetic.

Hōʻike ka papa ma lalo nei i ka hoʻohana nui ʻana o nā coils inductance i nā ʻōnaehana mana:

No ka hoʻonui ʻana i ka hana, pono e noʻonoʻo nā ʻenekinia i nā mea e like me ke kumu kumu, ka hoʻonohonoho ʻana i ka makani, a me ka hoʻokele wela. Hāʻawi ʻo Naheng Electronics i nā coils inductance ikaika i hoʻohālikelike ʻia no nā noi mana, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka pono i nā kaiapuni koi.

I ka hoʻouka ʻana ʻole a me nā lako kamaʻilio

Aia nā coils inductance i ka puʻuwai o nā ʻōnaehana hoʻoili uila a me nā mea kamaʻilio, hiki ke hoʻololi i ka ikehu kūpono a me ka hoʻouna ʻana i nā hōʻailona me ka ʻole o nā pilina kino.
