Pfungwa yeInductor

Inductors zvinhu zvinogona kushandura simba remagetsi kuita magineti simba uye kurichengeta. Mainductors akafanana muchimiro kune matransformer, asi ane mhepo imwe chete. Inductors ine imwe inductance, iyo inongovhara shanduko yezvino. Kana iyo inductor iri muhurumende umo pasina ikozvino inoyerera, ichaedza kuvhara ikozvino inoyerera kuburikidza nayo kana dunhu rakabatanidzwa. Kana iyo inductor iri mumamiriro ekuyerera kwemazuva ano, ichaedza kuchengetedza ikozvino isingashanduki kana dunhu rakabviswa.

Inductors inonziwo chokes, reactors uye dynamic reactors. Inductor inowanzo umbwa nefuremu, mahwindi, inovharira chivharo, yekurongedza zvinhu, magineti musimboti kana iron musimboti, etc. Inductance ireshiyo yemagineti inoyerera yeconductor kune yazvino ichigadzira inotsinhana magineti inoyerera yakatenderedza conductor kana conductor achipfuura. alternating current.

Apo DC ikozvino inoyerera kuburikidza ne inductor, chete yakagadziriswa magineti mutsara wesimba inooneka yakaipoteredza, iyo isingashanduki nenguva. Nekudaro, kana iyo inochinjika ikozvino ichipfuura nepakati coil, iyo magineti mitsara yakaitenderedza inochinja nekufamba kwenguva. Zvinoenderana nemutemo waFaraday we electromagnetic induction - magineti inogadzira magetsi, iyo yakachinjika magineti mitsara yesimba inoburitsa induction kugona kumigumo yese yecoil, iyo yakaenzana ne "simba idzva".

Inductors yakakamurwa kuita self inductors uye mutual inductors. Kana paine ikozvino mune coil, magineti minda inogadzirwa yakatenderedza coil.

Kana iyo iripo mucoil ichichinja, iyo magineti yakaitenderedza ichachinjawo zvinoenderana. Iyi yakashandurwa magineti inogona kuita kuti coil pachayo ibudise induced electromotive force (induced electromotive force) (simba remagetsi rinoshandiswa kumiririra terminal voltage yeakakodzera magetsi echinhu chinoshanda), inodaidzwa kuti self induction.

Kana maviri inductance coil ari padhuze kune mumwe nemumwe, iyo magineti shanduko yeimwe inductance coil ichakanganisa imwe inductance coil, iyo inonzi mutual inductance. Saizi yemutual inductor inotsamira pachiyero chekubatanidza pakati pekuzvipinza inductance yecoil inductance uye maviri inductance coil. Zvikamu zvakagadzirwa nekushandisa musimboti uyu zvinonzi mutual inductor.

Musika wekuvandudza mamiriro einductor indasitiri

Chip inductors inokamurwa ne inductor chimiro. Zvinoenderana nechikamu chechimiro uye maitiro ekugadzira, inductors akakamurwa kuita mapoka maviri: plug-in yakasimba inductors uye chip mounted inductors. Iyo huru yekugadzira tekinoroji yechinyakare plug-in inductors ndeye "mhepo", kureva kuti, conductor inokuvadzwa pane magineti musimboti kuumba inductive coil (inozivikanwawo sehollow coil).

Iyi inductor inoratidzwa nehupamhi hwemhando ye inductance, yakanyanya kunaka kweiyo inductance kukosha, simba rakakura, kurasikirwa kudiki, kugadzirwa kuri nyore, kupfupika kwekugadzira kutenderera, uye kukwana kwakakwana kwezvinhu zvakasvibiswa. Kukanganisa kwayo kwakadzikira dhigirii rekugadzira otomatiki, mutengo wakakwira wekugadzira, uye kuoma mu miniaturization uye kureruka.

Iyo China Electronics Indasitiri Association inofungidzira kuti musika wepasi rose weinductor uchakura ne7.5% pagore mumakore mashoma anotevera, China mutengi mukuru wezvishandiso zvemagetsi. Nekukurumidza kuchinja kwehunyanzvi hwekutaurirana kweChina uye nekuvaka kwakakura kweInternet Yezvinhu, maguta akangwara uye mamwe maindasitiri ane hukama, musika weChina chip inductor uchakura nekukurumidza kupfuura mwero wekukura kwepasirese. Kana chiyero chekukura chiri gumi muzana, saizi yemusika yeindasitiri yechip inductor ichapfuura mabhiriyoni gumi nemasere yuan. Zvinoenderana nedata, saizi yemusika wepasi rose inductor muna 2019 yaive 48.64 bhiriyoni yuan, kumusoro 0.1% gore negore kubva 48.16 bhiriyoni yuan muna 2018; Muna 2020, nekuda kwekukanganisa kweiyo pasi rose COVID-19, saizi yemusika yemainductors ichadzikira kusvika pamabhiriyoni makumi mana nemazana mana nemakumi mashanu nemana. Chiyero chemusika weChina inductor chinoratidza kukura. Muna 2019, chiyero chemusika weChina inductor chaive bhiriyoni RMB 16.04, kuwedzera kwe13% zvichienzaniswa neRMB 14.19 bhiriyoni muna 2018. Muna 2019, mari yekutengesa yeChina yakawedzera gore negore, kubva pa8.136 bhiriyoni yuan muna 2014 kusvika pamabhiriyoni gumi nematanhatu. muna 2019.

Zvinotarisirwa kuti kudiwa kwemusika kwemainductors kuchave kwakakura uye kukura, uye musika wepamba uchave wakafara. Muna 2019, China yakatumira kunze 73.378 bhiriyoni inductors uye kunze kwenyika 178.983 bhiriyoni inductors, 2.4 yakapetwa huwandu hwekutumira kunze.

Muna 2019, kukosha kwekutengesa kunze kweChina inductors kwaive US $ 2.898 bhiriyoni uye kukosha kwekunze kwaive US $ 2.752 bhiriyoni.

China yevatengi zvemagetsi indasitiri cheni yakasangana neshanduko iri kusimukira kubva mukugadzirwa kwezvikamu zvakaderera-zvakawedzerwa, OEM yemhando dzekunze dzekupedzisira kusvika pakupinda kwemhando yepamusoro-yekuwedzera-yakawedzera maratidziro ekugadzira, uye epamba ekupedzisira mabhureki ave emhando yepamusoro pasirese. Parizvino, kugadzirwa kwe smartphone kweChina kunokwana makumi manomwe muzana kana makumi masere muzana epasi rose, uye mabhizinesi eChinese anotonga epakati uye ekupedzisira nhanho dzepasi rose dzevatengi zvemagetsi indasitiri chain, gungano uye mamwe minda, Naizvozvo, pasi pechibvumirano cheindasitiri che "motokari inodiwa". senharembozha hombe” uye nekumashure uko makambani ezvemagetsi emagetsi maindasitiri akaiswa mumunda wemotokari dzakangwara, tarisiro yeindasitiri yemagetsi yevatengi vepamba mune ramangwana inofanirwa kutarisira.

Kuwedzera kwenhamba ye5G nhare mbozha frequency bands kwakawedzera zvakanyanya kushandiswa kwe single unit inductors. Iwo epasirese epamusoro-frequency inductors akatarisana negomba rakakura rekugona uye kusimba kwekupa. Kupfupisa, kutsiva kwe5G nharembozha kwakaunza kutenderera kutenderera. Kudiwa kwe inductance kwakaramba kuchiwedzera. Denda rakakonzera kubviswa kwemamwe ma inductance hofori. Dzimwe nzira dzemumba dzakavhura nzvimbo.
