Dzidza iyo inductance huwandu hwakazara-modhi inductance . Tevedza iyo inductance inogadzira (nehunyanzvi yakapihwa: axial inductor , TOUR inductor) kudzidza:
Kusiyanisa modhi yazvino: Zviratidzo zviviri zvehukuru hwakaenzana uye nzira yakatarisana pane mitsara yemasaini, inowanzo shandiswa mudunhu.
Iyo yazvino, yetambo yechiratidzo, ndiyo yazvino kuyerera pakati petambo yemutsara nenzvimbo yechiratidzo.
Yakajairika modhi yazvino: A maviri emasaini (kana ruzha) eiyo saizi uye kutungamira pane maviri eanosiyanisa masaini mitsara.
Kazhinji, ruzha rwepasi runotapurwa neyakajairwa modhi yazvino, saka inonziwo yakajairika modhi ruzha.
Kune nzira dzakawanda dzekutsikirira yakajairika-modhiyo ruzha. Pamusoro pekudzora ruzha-ruzha ruzha panobva, yakajairwa modhiyo inductance inowanzo shandiswa kusefa yakajairika-modhiyo ruzha, ndokuti, kuvharidzira yakajairika-modhiyo ruzha kunze kwetambo yedunhu. Chinangwa ndechekuwedzera iyo impedance yeyakajairika-modhi wedunhu kuitira kuti yakajairika-modhi yazvino idyiwe uye ivharwe (inoratidzwa) nekukachidzwa, nekudaro ichidzvinyirira yakajairika-modhiyo ruzha mudunhu.
Iwo musimboti weyakajairika-modhi kudzipwa kana inductor
Kana makoiri maviri akakuvadzwa munzira imwechete pane rin'i yemagineti yezvinhu zvemagineti, magnetic flux inogadzirwa muiyo coil nekuda kwemagetsi emagetsi induction kana inochinjika yazvino ichidarika nepapoiri. iyo rin'i yemagineti yakafanana muhukuru uye inopesana nedivi, uye iwo maviri anoregedzana, saka iyo kusiyanisa modhi impedance inogadzirwa nemagineti mhete iri diki kwazvo. Kune zvakajairika-modhi zviratidzo, iyo magnetic flux inogadzirwa ndeye yakafanana ukuru nongedzo, uye iwo maviri akaiswa pamusoro peumwe kuti aite yakakura yakajairika-modhi impedance yeinogadzira ring.Ichi chimiro chinoita kuti yakajairika modhi inductance ive nepesvedzero shoma pane yekusiyanisa modhi modhi uye ine zvirinani kusefa mashandiro kune yakajairwa modhi ruzha.
(1) Kana musiyano muoti parizvino uchipfuura neyakajairika-modhi coil, iyo yemagineti tambo iri munzira yakatarisana uye iyo inokonzerwa nemagineti inopera simba. Inogona kuonekwa kubva kudivi remagineti yemutsara mumufananidzo uri pazasi kuti museve wakasimba museve unomiririra iko iko ikozvino uye mutsetse wakakwenenzverwa unomiririra iko kunongedza kwemagineti
(2) Iyo yakajairika-modhi yazvino inodarika neyakajairika-modhi coil, uye iyo yemagineti inosimbiswa nekuda kwenzira imwecheteyo yemagineti mutsara mutsara. Inogona kuonekwa kubva kudivi remagineti yemutsara mumufananidzo uri pazasi kuti museve wakasimba museve unomiririra iko iko ikozvino uye mutsetse wakakwenenzverwa unomiririra iko kunongedzera kwemagineti
Yakajairika-modhi inductance yeoil kana inonzi self-induction coefficient, tinoziva kuti iyo inductance inogadzira kugona kwemagineti munda, yakajairwa modhi kana yakajairika-modhi inductor coil, apo yakajairika-modhi yazvino inoyerera kuburikidza neoiri, nekuda kwe iyo yemagineti mitsara munzira imwechete, pasina kufunga pasi pemamiriro ekudonha inductance, magnetic flux, musimboti wayo kufambidzana inductance, pazasi coil coil magnetic field mitsara kuburikidza nebhuruu, tsvuku uye bhuruu coil magineti mitsara zvakare kuburikidza ne tsvuku coil, induction mumwe nemumwe.
From the point of view of inductance, inductance is multiplied, magnetic chain represents the total magnetic flux, the common-mode inductor, when magnetic flux is doubled, circle number has not changed, the current didn't also did not change, so mean increased inductance for 2 times, means that the equivalent permeability into 2 times.
Sei kukwana kwakaringana kukwana kwakapetwa kaviri? Kubva pane inotevera inductance fomula, sezvo huwandu hwekutendeuka N haushanduke, iyo redunhu redunhu uye muchinjikwa-chikamu chikamu chemagineti musimboti chinotariswa neyakaenzana saizi yemagineti musimboti, saka hapana shanduko. Chikonzero chega ndechekuti kukwana U kunopetwa, saka magineti flux anogona kugadzirwa
Common-mode inductor in common mode, therefore, when an electric current passes through, work under the mutual inductance model, under the effect of mutual inductance, the equivalent inductance is cost increase, therefore common mode impedance will be multiplied, and the common mode signal has good filtering effect, also is the common mode signal with large impedance block, don't let it pass the common-mode inductor, also is not to let this signal transmission to the next level of the circuit, the following is the inductive reactance ZL.
Know common-mode inductor under the mode of common mode inductance, is the main clue to know mutual inductance, magnetic components of all, no matter what name as long as mastering the form of the change of the magnetic field, magnetic field changes through the phenomenon to essence, also easy to understand, moreover we always grasp the magnetic field lines, it is our understanding the visual form of the magnetic field, consider whether the same side or different name or concept of the mutual inductance phenomenon or magnetic field, we are drawing the lines of magnetic force to realize their - master "magnet winding method" is explained before.
