ʻO ka pōʻai ʻiʻo thermosetting electromagnetic coil QVT306

He aha nā ʻano o nā ʻāpana inductance?

1. ʻO ke kumu o ka maikaʻi:

ʻO ke kumu maikaʻi Q kahi mea i hoʻohana ʻia no ke ana ʻana i ka pilina ma waena o ka ikehu i mālama ʻia e nā mea hoʻopaʻa ikehu (inductors a i ʻole capacitors) a me ka hoʻohana ʻana i ka ikehu, i hōʻike ʻia penei: Q=2π ka nui o ka ikehu mālama ʻia. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka waiwai Q o ka inductance coil, ʻoi aku ka maikaʻi, akā ʻoi aku ka nui e hōʻino i ka paʻa o ke kaapuni hana.

2, ka Inductance:

Ke hoʻololi ke au i loko o kahi wili, hoʻololi ke kahe magnetic e hele ana ma ka loop loop i hoʻokumu ʻia e ke au i hoʻololi ʻia, e hoʻoulu ai ka coil ponoʻī i ka ikaika electromotive. ʻO ka coefficient inductance ponoʻī kahi nui kino e hōʻike ana i ka hiki ke hoʻokomo ponoʻī o kahi coil. Ua kapa ʻia ʻo ia hoʻi ʻo self-inductance a i ʻole inductance. Ua hōʻike ʻia e L. ʻO ka lawe ʻana iā Henry (H) ma ke ʻano he hui, ua kapa ʻia ka hapahā tausani o ka millihenh (mH), ʻo ka hapa miliona i kapa ʻia ʻo millihenh (H), a ʻo ka hapa tausani o ia mea i kapa ʻia ʻo Nahen (NH).

3. Kū'ē DC (DCR):

I ka hoʻolālā inductance, ʻoi aku ka liʻiliʻi o ke kūpaʻa DC, ʻoi aku ka maikaʻi. ʻO ka ʻāpana ana he ohm, i hōʻailona maʻamau ʻia e kona waiwai nui.

4, ke alapine paʻi paʻa ponoʻī:

ʻAʻole ʻo Inductor kahi mea inductive maʻemaʻe, akā loaʻa pū kekahi i ke kaumaha o ka capacitance puʻupuʻu. ʻO ka resonance i kekahi alapine i hoʻokumu ʻia e ka inductance inherent a me ka hoʻokaʻawale ʻana i ka capacitance o ka inductor ponoʻī i kapa ʻia ʻo self-harmonic frequency, i ʻike ʻia ʻo ka resonance frequency. Hōʻike ʻia ma SRF, ʻo ka megahertz (MHz).

5. Waiwai Impedance:

ʻO ka waiwai impedance o kahi inductor e pili ana i ka huina o kāna mau impedances ma lalo o kēia manawa (helu paʻakikī), me nā ʻāpana kamaʻilio a me DC. ʻO ka waiwai impedance o ka ʻāpana DC ʻo ia wale nō ke kūʻē DC o ka wili (ʻāpana maoli), a ʻo ka waiwai impedance o ka ʻāpana kamaʻilio e pili ana i ka reactance (ʻaoʻao noʻonoʻo) o ka inductor. Ma kēia ʻano, hiki ke manaʻo ʻia ka inductor ma ke ʻano he "resistor kamaʻilio". 6. Hōʻike ʻia i kēia manawa: ʻae ʻia ka ikaika o ka DC i kēia manawa e hiki ke hele i kahi inductor. Hoʻokumu ʻia ka ikaika o ka DC i kēia manawa ma luna o ka piʻi ʻana o ka wela kiʻekiʻe o ka inductor i ke kiʻekiʻe o ka wela ambient. ʻO ke ʻano o kēia manawa e pili ana i ka hiki o kahi inductor e hōʻemi i ka nalowale o ka wili e ka haʻahaʻa haʻahaʻa DC, a pili pū kekahi i ka hiki o ka inductor e hoʻopau i ka nalowale o ka ikehu wili. No laila, hiki ke hoʻomaikaʻi ʻia ke ʻano o kēia manawa ma ka hōʻemi ʻana i ke kūpaʻa DC a i ʻole ka hoʻonui ʻana i ka pālākiō inductance. No nā ʻano nalu o kēia manawa haʻahaʻa, ʻo kona kumu ke kumu kūʻai huinahā
