Electromagnetic coil 14550884 no Volvo excavator

Hoʻoponopono i nā hōʻailona hana nui

ʻO ka helu hana o ka inductance coil ka nui o ka inductance. Eia kekahi, ʻo ka ʻōlelo maʻamau, ʻo ka ʻeha uea me ka inductance coil mau ke kūʻē ʻana, ʻo ia ka mea liʻiliʻi loa a hiki ke mālama ʻole ʻia. Eia naʻe, inā nui loa ke kahe o ke au i kekahi mau kaapuni, ʻaʻole hiki ke nānā ʻole ʻia kēia kūʻē liʻiliʻi o ka wili, no ka mea, e hoʻopau ke au nui i ka mana ma luna o ka pōʻai, e wela a wela paha ka wili, no laila i kekahi manawa ka uila. ka mana i hiki i ka wili ke pale aku pono e noonoo.

Inductance

Hōʻike ka inductance l i nā hiʻohiʻona o ka coil ponoʻī, me ka nānā ʻole i kēia manawa. Koe wale no ka coil inductance kūikawā (color-coded inductance), ʻaʻole i hōʻailona kūikawā ʻia ka inductance ma ka coil, akā kaha ʻia me kahi inoa kikoʻī. ʻO ka Inductance, ka mea i ʻike ʻia he coefficient inductance ponoʻī, he nui kino e hōʻike ana i ka hiki o ka inductance ponoʻī o ka inductor. ʻO ka inductance o ka inductor e hilinaʻi nui ʻia i ka helu o ka huli ʻana o ka coil, ke ʻano wili, ka hele ʻana a i ʻole ka ʻole o ke kumu a me nā mea o ke kumu, a pēlā aku. ʻoi aku ka nui o ka inductance. ʻOi aku ka nui o ka inductance o ka coil me ka magnetic core ma mua o ka coil me ka ʻole magnetic core; ʻOi aku ka nui o ka magnetic permeability o ke kumu, ʻoi aku ka nui o ka inductance.

ʻO ka ʻāpana kumu o ka inductance ʻo Henry (Hen no ka pōkole), i hōʻike ʻia e ka leka "H". ʻO nā ʻāpana maʻamau ʻo milli-Heng (mH) a me micro-Heng (μH), a ʻo ka pilina ma waena o lākou:

1H=1000mH

1mH=1000μH

Ka hoʻohaunaele inductive

ʻO ka nui o ke kūpaʻa o ka inductance coil i ka AC i kēia manawa ua kapa ʻia ʻo inductance XL, me ka ohm ka ʻāpana a me ka ω ka hōʻailona. ʻO kona pilina me ka inductance L a me ke alapine AC F he XL=2πfL.

kumu waiwai

ʻO ke kumu maikaʻi Q ka nui kino e hōʻike ana i ka maikaʻi o ka coil, a ʻo Q ka ratio o ka inductance XL i kona kūpaʻa like, ʻo ia hoʻi, Q = XL/R. Ke hana nei ka inductor ma lalo o kekahi alapine AC. ʻO ke kiʻekiʻe o ka waiwai Q o ka inductor, ʻoi aku ka liʻiliʻi o ka nalowale a ʻoi aku ka kiʻekiʻe o ka pono. ʻO ka waiwai q o ka coil e pili ana i ke kū'ē DC o ka conductor, ka poho dielectric o ka iwi iwi, ka poho i hanaʻia e ka pale a iʻole ka hao hao, ka hopena o ka hopena o kaʻili kiʻekiʻe a me nā mea'ē aʻe. ʻO ka waiwai q o ka pōʻai he ʻumi a hiki i nā haneli. ʻO ke kumu maikaʻi o ka inductor e pili ana i ke kūpaʻa DC o ka uea coil, ka nalowale o ka dielectric o ka pahu coil a me ka nalowale i kumu a me ka pale.
