Thermosetting DIN43650A pilina electromagnetic coil SB254/A044

He kumu waiwai q o ka coil inductance

1. ʻO ka helu q kahi mea nui e hōʻike i ka maikaʻi o ka coil. ʻO ka nui o Q hōʻike i ka nalowale o ka inductance coil. ʻO ka nui o ka Q, ʻoi aku ka liʻiliʻi o ka nalowale o ka wili. ʻOi aku ka nui o ka poho.

2. ʻO ka mea maikaʻi Q ka mea i wehewehe ʻia e like me ka ratio o ka inductance o ka coil i ke kūpaʻa DC o ka coil i ka wā e hana ai ka coil i kekahi alapine AC voltage. Hiki ke hōʻike ʻia ma ke ʻano penei:

3.Where: W-hana angular frequency L-coil inductance R-pau poho kū'ē o ka coil

4.According i nā manawa likeʻole,ʻokoʻa nā koi no ka mea maikaʻi Q. No ka wili inductance i ka loop tuning, ʻoi aku ka kiʻekiʻe o ka waiwai q, no ka mea ʻoi aku ka kiʻekiʻe o ka waiwai q, ʻoi aku ka liʻiliʻi o ka nalowale o ka loop a ʻoi aku ka kiʻekiʻe o ka pono o ka loop; No ka wili hui, hiki ke emi iho ka waiwai q; No ka haʻahaʻa-frequency a kiʻekiʻe-frequency chokes, ʻaʻohe koi.

5. I ka ʻoiaʻiʻo, ʻo ka hoʻomaikaʻi ʻana o ka waiwai Q ua kaupalena pinepine ʻia e kekahi mau mea, e like me ke kūpaʻa DC o ka conductor, ka nalowale o ka dielectric o ka bobbin, ka poho i kumu a me ka pale, a me ka hopena o ka ʻili i ka wā e hana ai. alapine kiʻekiʻe. No laila, ʻaʻole hiki ke kiʻekiʻe loa ka waiwai Q o ka wili. ʻO ka maʻamau, ʻo ka waiwai Q he mau ʻumi a hoʻokahi haneri, a ʻo ka mea kiʻekiʻe loa he 500 wale nō.

6. I ke koho ʻana i ke kumu magnetic, pono e noʻonoʻo nui ʻia nā koi o ka hana pinepine a me ka waiwai Q. I ka wā ma lalo o 1MHz ke alapine hana maʻamau, pono e hoʻohana pono ʻia ke kumu magnetic i hana ʻia me ka manganese-zinc ferrite; Ke kiʻekiʻe ke alapine hana ma mua o 1MHz, pono ke koho ʻia ke kumu magnetic i hana ʻia me Ni-Zn-Fe-O. Ma lalo o ke kūlana o ka waiwai Q kiʻekiʻe a me ke alapine hana haʻahaʻa, pono ke koho ʻia ka nui nui magnetic core.

7. I ke koho ʻana i ke kumu magnetic, pono e noʻonoʻo nui ʻia nā koi o ka hana pinepine a me ka waiwai Q. I ka wā ma lalo o 1MHz ke alapine hana maʻamau, pono e hoʻohana pono ʻia ke kumu magnetic i hana ʻia me ka manganese-zinc ferrite; Ke kiʻekiʻe ke alapine hana ma mua o 1MHz, pono ke koho ʻia ke kumu magnetic i hana ʻia me Ni-Zn-Fe-O. Ma lalo o ke kūlana o ka waiwai Q kiʻekiʻe a me ke alapine hana haʻahaʻa, pono ka spool nui
