Thermosetting plastic package type small solenoid valve coil AN1024

ʻO ke ʻano helu helu no ka inductance motor, inductance coil, electromagnetic coil

1. ʻO ke kaʻina moʻohelu inductance ʻO ka moʻo inductance moʻokalaleo (malia paha ka helu helu reactance, ʻo ka ʻokoʻa ma waena o nā mea ʻelua he alapine angular uila o 2 × Txf) e hoʻoholo i ka hana o ka kaʻa, ʻo ia ke kumu nui no ka nānā ʻana a me ka hoʻolālā ʻana.

2. No nā kaʻa me ka ʻokoʻa ea ea, e like me asynchronous motors, no ka mea, ua like ke ʻano o ka hawewe puʻupuʻu magnetic a me ka hawewe mānoanoa, ʻokoʻa lākou ma muli o ka maʻa mau o ke ea, no laila, pono e hoʻohui ʻia ka nalu mānoanoa. loaʻa i ka loulou flux a me ka inductance. No nā kaʻa me nā ʻāpana ea like ʻole, e like me nā kaʻa synchronous a me nā ʻenekini hoʻololi i hoʻololi ʻia, ʻaʻole hilinaʻi wale ka hawewe mānoanoa ma luna o ka mana magnetic, akā i ke ʻano o ke ʻano o ka ea. Ma muli o ka ʻokoʻa ʻole o ka ea, ʻoi aku ka paʻakikī o ka helu ʻana i ka inductance. I kēia manawa, hiki ke koho ʻia ʻelua ala. ʻO kekahi ke ʻano o ka ʻeleʻele palena. I ka lōʻihi o ke kūkulu ʻia ʻana o ke kumu hoʻohālike, e helu ikaika ka polokalamu i ka mānoanoa a me ka inductance. Akā i kekahi manawa pono e ʻike i ka hopena analytical o ka inductance, kahi kūpono no ka loiloi qualitative o ka kaʻa. I kēia manawa, hiki ke hoʻohana ʻia ke ʻano i kapa ʻia ʻo permeance function analysis. ʻO ke ʻano loiloi o ka hana permeance ʻo ia ka hoʻoheheʻe ʻana i nā nalu alakaʻi magnetic e Fourier no ka loaʻa ʻana o nā huaʻōlelo mau, nā nalu kumu a me nā nalu alakaʻi magnetic kiʻekiʻe. I mea e hoʻoholo ai i ka huina Fourier i loko o ka hana permeance āpau o ka ea, pono e hoʻohana i ke ʻano mea palena palena no ka nānā ʻana i kahi ʻohana o nā pihi permeance kikoʻī. Ma ka hoʻoholo ʻana i ka hana permeance āwaha ea, hiki iā mākou ke helu i ka ea ākea magnetic density = air gap magnetic potential × air gap permeance function. I ka loaʻa ʻana o ka mānoanoa magnetic gap ea, hiki ke helu ʻia ka loulou flux a me ka inductance e ke ʻano hoʻohui like e like me ke ʻano o ke kaʻa like ʻole ea.
