He mea maʻalahi ka inductor e like me ka mea e hiki ke loaʻa i ka mea uila - he wili uea wale nō ia. ʻIke ʻia naʻe, hiki i kahi wili uea ke hana i kekahi mau mea hoihoi loa ma muli o nā waiwai magnetic o kahi wili.

Ma kēia ʻatikala, e aʻo mākou i nā mea a pau e pili ana i nā inductors a me nā mea e hoʻohana ai lākou.

ʻIkepili

Nā Kuleana Inductor

ʻO Henry

Hoʻohana Inductor: Nā ʻike kukui uila

Nā Kuleana Inductor

Ma ke kiʻikuhi kaapuni, hōʻike ʻia kahi inductor penei:

No ka hoʻomaopopo ʻana pehea e hiki ai i kahi inductor ke hana i kahi kaapuni, kōkua kēia helu:

ʻO ka mea āu e ʻike ai ma ʻaneʻi, he pākaukau, he ʻōpuʻu kukui, he wili uwea a puni kahi ʻāpana hao (melemele) a me kahi kī. ʻO ka wili o ka uea he inductor. Inā ua heluhelu ʻoe pehea e hana ai nā Electromagnets, ʻike paha ʻoe he electromagnet ka inductor.

Inā ʻoe e lawe i ka inductor mai kēia kaapuni, ʻo ka mea āu e loaʻa ai he kukui uila maʻamau. Hoʻopili ʻoe i ke kuapo a ʻā ke kukui. Me ka inductor i ke kaapuni e like me ka mea i hōʻike ʻia, ʻokoʻa loa ka ʻano.

ʻO ka ʻōpuʻu kukui he mea pale (hana ke kū'ē i ka wela e hoʻomālamalama i ka filament i loko o ka puʻupuʻu - e ʻike pehea e hana ai nā ʻōpuʻu kukui no nā kikoʻī). He haʻahaʻa loa ke kūʻē ʻana o ka uea i loko o ka pōʻai (he uea wale nō ia), no laila ʻo ka mea āu e manaʻo ai ke hoʻā ʻoe i ke kuapo no ka ʻālohilohi ʻana o ka puʻupuʻu. Pono ka hapa nui o kēia manawa e hahai i ke ala haʻahaʻa haʻahaʻa ma o ka loop. ʻO ka mea e hiki mai ana, ke pani ʻoe i ke kuapo, e ʻā aʻe ka puʻupuʻu a laila e emi iho. Ke wehe ʻoe i ka hoʻololi, ʻaʻā loa ka puʻupuʻu a laila pio koke.

ʻO ke kumu o kēia ʻano ʻano ʻē ka inductor. I ka hoʻomaka mua ʻana o ke kahe ʻana i loko o ka wili, makemake ka coil e kūkulu i kahi māla magnetic. ʻOiai ke kūkulu ʻia nei ke kahua, hoʻopaʻa ka coil i ke kahe o ke au. Ke kūkulu ʻia ke kahua, hiki ke kahe maʻamau ma o ka uea. Ke wehe ʻia ka hoʻololi, hoʻomau ke kahua magnetic a puni ka coil i ke kahe ʻana o ka wili a hiki i ka hāʻule ʻana o ke kula. Mālama kēia au i ke kukui no kekahi manawa ʻoiai ua hāmama ke kī. I nā huaʻōlelo ʻē aʻe, hiki i kahi inductor ke mālama i ka ikehu i loko o kāna māla magnetic, a ʻo kahi inductor e pale i ka hoʻololi ʻana i ka nui o ke kahe o kēia manawa.

E noʻonoʻo e pili ana i ka wai…

ʻO kahi ala e ʻike ai i ka hana a ka mea hoʻokomo, ʻo ia ka noʻonoʻo ʻana i kahi kahawai haiki me ka wai e kahe ana ma loko, a me kahi huila wai kaumaha e komo ana nā hoe i loko o ke kahawai. E noʻonoʻo ʻaʻole kahe ka wai ma ke kahawai ma mua.

I kēia manawa e hoʻomaka ʻoe e kahe ka wai. ʻO ka huila hoe ʻaʻole e kahe ka wai a hiki i ka wikiwiki o ka wai. Inā ʻoe e hoʻāʻo e hoʻōki i ke kahe ʻana o ka wai i loko o ke kahawai, e hoʻāʻo ka huila wai e hoʻomau i ka neʻe ʻana o ka wai a hiki i kona wikiwiki o ka hoʻololi ʻana i ka wikiwiki o ka wai. Ke hana like nei ka mea hoʻoheheʻe me ke kahe o nā electrons i loko o kahi uea - ke kūʻē nei kahi inductor i ka hoʻololi ʻana i ke kahe o nā electrons.

E heluhelu hou

ʻO Henry

Hoʻomalu ʻia ka mana o kahi inductor e nā kumu ʻehā:

ʻO ka helu o nā coils - ʻOi aku ka nui o nā coils i ke ʻano o ka inductance.

ʻO ka mea i hoʻopaʻa ʻia nā wili a puni (ke kumu)

ʻO ka ʻāpana cross-sectional o ka coil - ʻOi aku ka nui o ka nui o ka inductance.

ʻO ka lōʻihi o ka coil - ʻO kahi wili pōkole ʻo ia ka mea ʻoi aku ka liʻiliʻi (a i ʻole overlapping), ʻo ia hoʻi ka ʻoi aku o ka inductance.

ʻO ka hoʻokomo ʻana i ka hao i loko o ke kumu o kahi inductor e hāʻawi iā ia i ʻoi aku ka nui o ka inductance ma mua o ka ea a i ʻole kekahi kumu non-magnetic.

ʻO ka ʻāpana maʻamau o ka inductance ka henry. ʻO ka hoohalike no ka helu ʻana i ka helu o nā henries i loko o kahi mea hoʻokomo:

H = (4 * Pi * #Huli * #Huli * Huli wili * mu) / (Loihi wili * 10,000,000)

ʻO ka ʻāpana a me ka lōʻihi o ka wili i nā mika. ʻO ka huaʻōlelo mu ka permeability o ke kumu. He 1 ka ea, a he 2,000 ka hiki ke kila.

Hoʻohana Inductor: Nā ʻike kukui uila

E ʻōlelo kākou e lawe ʻoe i kahi wili uwea he 6 kapuaʻi (2 mika) ke anawaena, nona nā puka lou ʻelima a ʻeono paha. Ua ʻoki ʻoe i kekahi mau ʻāwīwī ma ke alanui a kau i ka wili i loko o nā ʻauwaha. Hoʻopili ʻoe i kahi mika inductance i ka coil a ʻike i ke ʻano o ka inductance o ka coil.

I kēia manawa, kau ʻoe i kahi kaʻa ma luna o ka coil a nānā hou i ka inductance. E ʻoi aku ka nui o ka inductance ma muli o ka mea kila nui i hoʻonoho ʻia i loko o ke kahua magnetic o ka loop. ʻO ke kaʻa i hoʻopaʻa ʻia ma luna o ka coil ke hana nei e like me ke kumu o ka inductor, a ʻo kona hele ʻana e hoʻololi i ka inductance o ka coil. Hoʻohana ka hapa nui o nā mea ʻike kukui uila i ka loop ma kēia ʻano. Ke ho'āʻo mau nei ka mea ʻike i ka inductance o ka loop ma ke alanui, a i ka wā e piʻi ai ka inductance ʻike ʻo ia aia kahi kaʻa e kali ana!

Hoʻohana maʻamau ʻoe i kahi coil liʻiliʻi loa. ʻO kahi hoʻohana nui o nā inductors e hui pū me lākou me nā capacitors e hana i nā oscillators. E ʻike pehea e hana ai nā Oscillators no nā kikoʻī.
