I-shaped inductorchinhu chinonzi electromagnetic induction component inoumbwa neI-shaped magnetic core skeleton uye enamelled copper waya, inogona kushandura masaini emagetsi kuita magineti masaini.

Iyo I-shaped inductor pachayo inductor.Inobva kune skeleton chimiro, iyo yakafanana neI-yakaita, uye coil mhepo mu slot ye "I".Yedu yakajairika inductors ndeyechip inductors, RF inductors,magetsi inductors, common mode inductors, magnetic loop inductors, etc. Nhasi, hatisi kuzounza aya inductors.Ndeapi ma inductors?Ndiyo I-shaped inductor

Ini-yakaumbwa Inductor Core mufananidzo

Seimwe ye-plug-in inductors, I-shaped inductor haisi mudiki diki, asiwo nyore kuisa, iyo i-plug-in type inductor uye inotora nzvimbo shoma;High Q factor;Iyo yakagoverwa capacitance idiki;High self resonance frequency;Special guide tsono chimiro, kwete nyore kugadzira yakavharwa redunhu chiitiko.

TheI-shaped inductorinoshandisa conductor kupfuudza iyo AC voltage uye yazvino.Iyo I-shaped inductance ndiyo chiyero chemagnetic flux ye conductor kune yazvino inogadzira iyo alternating magnetic flux yakatenderedza conductor kana conductor achipfuura AC ikozvino.I-shaped inductor inowanzo shandiswa kuenzanisa dunhu uye chiratidzo chemhando yekudzora, uye kazhinji yakabatana nemagetsi.

Kugadzikana kweI-shaped inductor yakakwirira kudarika iyo general inductor.Ikozvino inopfuura nepakati pedunhu yakanyatsogadzikana, uye kubudirira kunovandudzwawo zvakanyanya.Basa guru reI-shaped inductor ndere kusefa masaini, ruzha rwesefa, kudzikamisa yazvino uye kudzora kupindira kwemagetsi, inova yakanakisa chiyero cheEMI.Nhasi, ndinoda kugoverana newe nezve chimiro uye maitiro eI-shaped inductor.

Chimiro uye kuumbwa kweI-shaped inductor

Iyo hurongwa hweI-shaped inductor inoumbwa nerutsigiro rwemhepo yemhangura core coil.I-shaped inductor ndechimwe chezvinhu zvemagetsi edunhu kana mudziyo, izvo zvinoreva: kana zvazvino zvachinja, mamwe mahombe akagadziriswa inductors kana anochinjika inductors (senge oscillating coil, ikozvino inopikisa coil, nezvimwewo) inoburitsa simba remagetsi kurwisa. shanduko yazvino nekuda kwe electromagnetic induction.

Iyo inowanzoshandiswa I-shaped inductor inoonekwa seyakamira vhezheni yeaxial inductor, iyo yakafanana neaxial inductor mukureruka kwekushandisa.Zvisinei, iyo inowanzoshandiswa I-shaped inductor inogona kuva nemhando yakakura ye inductance, uye ikozvino inogona kuvandudzwa mukushandiswa;

Kazhinji, enamelled waya (kana shinda yakaputirwa waya) yakanyatsokuvadzwa paskeleton, uye ipapo iyo magineti core, copper core, iron core, nezvimwe zvinoiswa mukati memukati memhango yeskeleton kuti ivandudze inductance yayo.

Iyo skeleton inowanzogadzirwa nepurasitiki, bakelite uye ceramics, uye inogona kugadzirwa mumhando dzakasiyana zvichienderana nezvinodiwa chaizvo.Madiki inductive coils (akadai seI-shaped inductors) kazhinji haashandise skeleton, asi zvakananga mhepo ine enamelled waya pane iyo magineti musimboti.

Hunhu hweI-shaped inductor

1. Diki yakatwasuka inductor, inogara diki yekuisa nzvimbo;

2. Diki yakagoverwa capacitance uye yakakwirira self resonance frequency;

3. Iyo yakakosha yepini inotungamira chimiro haisi nyore kukonzeresa yakavhurika dunhu.

4. Chengetedza nePVC kana UL inopisa inopisa sleeve.

5. Tungamira mahara kuchengetedzwa kwezvakatipoteredza.

Hunhu hweI-shaped inductor

1. Inductance value range: 1.0uH kusvika 100000uH.

2. Yakatemerwa ikozvino: zvichienderana nekukwira kwekushisa, haifaniri kudarika 200C.

3. Kushanda tembiricha siyana: - 20oC kusvika 80oC.

4. Terminal simba: kupfuura 2.5 kg.

Basa reI-shaped inductor

1. Kuchengetedzwa kwemagetsi uye kusefa mumagetsi anoita kuti magetsi ekuratidzira awedzere kugadzikana.

2. Oscillation, iyo inoumba oscillation chikamu mu switching circuit kuwedzera simba

3. Anti interference uye anti interference: inoita seyakavhunga mumagetsi emagetsi uye yakasiyana-siyana inductor yekudzivirira harmonic zvikamu mumagetsi emagetsi kubva pakusvibisa girasi remagetsi uye kupindira nemagetsi, kutamba basa rakagadzikana.

Zvizhinji zvemagetsi zvigadzirwa zvine RF inductors."Kuti titevere mhuka, chubhu yegirazi yakaiswa muganda rezvipfuwo zvedu ine inductor mukati," akadaro Maria del Mar Villarrubia, injinjini yekutsvagisa nekusimudzira wePlummer Company."Pese panotangwa mota, kutaurirana pasina waya kunogadzirwa pakati pemainductors maviri, imwe mukati memota uye imwe mukati mekiyi."

Nekudaro, sekunge zvinhu zvakadaro zviri pese pese, maRF inductors anewo chaiwo maapplication.Mune resonant circuit, zvinhu izvi zvinowanzo shandiswa pamwe chete ne capacitors kusarudza imwe frequency (yakadai se oscillating circuit, voltage controlled oscillator, nezvimwewo).

RF inductors inogona zvakare kushandiswa mukupedance yekufananidza maapplication kuti uwane impedance chiyero chemitsara yekufambisa data.Izvi zvinodiwa kuti uve nechokwadi chekufambiswa kwedata pakati peICs.

Kana ichishandiswa seRF choke, inductors akabatanidzwa munhevedzano mudunhu kuita seRF mafirita.Muchidimbu, RF choke ndeye yakaderera-pass sefa, iyo inoderedza mafambiro epamusoro, nepo yakaderera mafrequency isingadzivirirwe.

Chii chinonzi Q kukosha?

Paunenge uchikurukura nezvekuita kwe inductance, Q kukosha chiyero chakakosha.Q kukosha indekisi yekuyera kuita kwe inductance.Iyo idimensionless parameter inoshandiswa kuenzanisa iyo oscillation frequency uye simba rekurasikirwa kwesimba.

Iyo yakakwira iyo Q kukosha, padyo nekuita kweinductor kune yakakodzera kurasikirwa inductor.Ndiko kuti, ine zviri nani selectivity mumutambo we resonant.

Imwe mukana wepamusoro Q kukosha kurasikirwa kwakaderera, ndiko kuti, simba shoma rinopedzwa neinductor.Yakaderera Q kukosha kunozokonzera yakakura bandwidth uye yakaderera resonance amplitude pa uye padyo neiyo oscillation frequency.

Inductance kukosha

Pamusoro peQ factor, iyo chaiyo kuyerwa kweinductor ndeyechokwadi yayo inductance kukosha.Kune maodhiyo uye masimba ekushandisa, kukosha kweiyo inductance kunowanzo kuve Henry, nepo yakakwirira frequency application inowanzoda diki inductance, kazhinji muhuwandu hwemillihenry kana microhenry.

Iko inductance kukosha kunoenderana nezvakati wandei zvinhu, zvinosanganisira chimiro, core size, core material uye chaiyo coil inotendeuka.Inductance inogona kugadziriswa kana kugadziriswa.

Kushandiswa kweI-shaped Inductor

I-shaped inductor inowanzoshandiswa mu: TV uye audio equipment;Michina yekukurukurirana;Buzzer uye alarm;Power controller;Masisitimu anoda Broadband uye yakakwirira Q kukosha.

Kuburikidza nekunzwisisa kwepamusoro kwekuita, maitiro uye mabasa eI-shaped inductor, tinogona kudzidza kuti I-shaped inductor inoshandiswa zvakanyanya mumotokari yakasungirirwa GPS, motokari yakasungirirwa DVD, magetsi emagetsi, rekodhi rekodhi, LCD kuratidza, komputa. , midziyo yemumba, matoyi, zvigadzirwa zvedhijitari, tekinoroji michina uye zvimwe zvigadzirwa zvemagetsi.

Kana iwe uchida mamwe mashoko, ndapota inzwa wakasununguka kutaura nesu.
