Inductive coils, raws li cov khoom tseem ceeb hauv circuits, yog dav siv nyob rau hauv tsheb, xws li solenoid li qub, motors, generators, sensors, thiab tswj modules.Nkag siab txog cov yam ntxwv ua haujlwm ntawm cov coils kom raug nteg lub hauv paus ruaj khov rau kev paub txog kev ua haujlwm ntawm cov khoom siv no.
Kev ua haujlwm ntawm inductors rau tsheb tswj kev hloov pauv.Cov inductor siv hauv tsheb yog ib qho ntawm peb qhov tseem ceeb hauv cov khoom siv hluav taws xob.
Cov inductors siv nyob rau hauv tsheb yog tsuas yog siv nyob rau hauv ob lub ntsiab hauv qab no: cov khoom siv hluav taws xob ib txwm siv, xws li lub suab tsheb, cov twj paj nruag, tsheb teeb, thiab lwm yam. Qhov thib ob yog los txhim kho kev nyab xeeb, kev ruaj ntseg, kev nplij siab, thiab kev lom zem khoom ntawm lub tsheb, xws li ABS, airbags, fais fab tswj tshuab, chassis tswj, GPS, thiab lwm yam.
Lub ntsiab yog vim li cas vim li cas inductors siv nyob rau hauv lub tsheb yog dav siv nyob rau hauv lub automotive kev lag luam yog vim lub hnyav ua hauj lwm ib puag ncig, siab vibration, thiab kub yuav tsum tau.Yog li ntawd, ib qho kev ua haujlwm siab tau raug teeb tsa los txhawb cov khoom siv hluav taws xob kom nkag mus rau qhov kev lag luam no.
Ob peb feem ntau siv automotive inductors thiab lawv cov functions.Lub Tuam Tshoj automotive electronics kev lag luam tau nkag mus rau ib lub sij hawm ntawm kev loj hlob sai, tsav tsheb qhov kev thov rau magnetic Cheebtsam.Vim yog qhov chaw ua haujlwm hnyav, kev co siab, thiab kev kub siab ntawm lub tsheb, cov kev xav tau zoo rau cov khoom siv hlau nplaum tshwj xeeb yog nruj.
Muaj qee qhov ntau hom ntawm automotive inductors:
1. High tam sim no inductance
Dali Electronics tau pib lub tsheb inductor nrog qhov loj ntawm 119, uas tuaj yeem siv rau hauv qhov kub ntawm -40 txog + 125 degrees.Tom qab siv 100V DC voltage ntawm lub kauj thiab cov hlau nplaum sib nqus rau 1 feeb, tsis muaj kev puas tsuaj los yog kev puas tsuaj R50 = 0.5uH, 4R7 = 4.7uH, 100 = 10uH inductance tus nqi.
2. SMT fais fab inductance
Lub tsheb inductor yog CDRH series inductor, nrog rau 100V DC voltage siv nruab nrab ntawm cov kauj thiab cov hlau nplaum, thiab cov rwb thaiv tsev tsis zoo tshaj 100M Ω Qhov inductance qhov tseem ceeb rau 4R7 = 4.7uH, 100 = 10uH, thiab 101 = 100uH.
3. High tam sim no, siab inductance hwj chim inductors rau hluav taws xob tsheb
Qhov tseeb tshiab tshiab shielded hwj chim inductor nyob rau hauv kev ua lag luam yog tsim rau hluav taws xob tsheb pib nres systems uas yuav tsum tau muaj tam sim no fais fab mov thiab lim, nrog inductance tus nqi ntawm 6.8 mus rau 470?H. Qhov ntsuas tam sim no yog 101.8A.Dali Electronics tuaj yeem muab cov khoom lag luam customized nrog cov nqi tsim nyog rau cov neeg siv khoom.
Los ntawm cov khoom tshiab saum toj no ntawm automotive electronics magnetic Cheebtsam, nws tuaj yeem pom tau tias nrog kev siv ntau yam kev siv hauv tsheb siv hluav taws xob, cov khoom sib nqus tau txhim kho mus rau qhov muaj zaus, tsawg poob, kub tsis kam, thiab muaj zog tiv thaiv kev cuam tshuam.Dali Electronics tau ua tiav cov txiaj ntsig kev tshawb fawb zoo tshaj plaws hauv automotive inductors / transformers.
Nov yog qee qhov kev ua haujlwm ntawm automotive fais fab inductors: tam sim no thaiv cov nyhuv: Tus kheej induced electromotive quab yuam nyob rau hauv lub kauj ib txwm tawm tsam qhov kev hloov ntawm tam sim no nyob rau hauv lub kauj.Nws tuaj yeem muab faib ua ntau zaus choke coils thiab qis zaus choke coils.
Tuning thiab xaiv zaus muaj nuj nqi: Inductive coils thiab capacitors tuaj yeem txuas nrog rau qhov sib npaug los ua ib qho LC tuning circuit.Yog hais tias lub ntuj oscillation zaus f0 ntawm lub Circuit Court yog sib npaug zos zaus f ntawm cov tsis yog AC teeb liab, ces inductance thiab capacitance ntawm lub Circuit Court kuj sib npaug.Yog li ntawd, electromagnetic zog oscillates rov qab thiab tawm ntawm inductance thiab capacitance, uas yog lub resonance tshwm sim ntawm LC Circuit Court.Thaum lub sij hawm resonance, vim qhov sib npaug ntawm qhov sib npaug ntawm inductance thiab capacitance ntawm lub voj voog, qhov inductance ntawm tag nrho cov tam sim no hauv Circuit Court yog qhov tsawg tshaj plaws thiab qhov tam sim no yog qhov loj tshaj plaws (xa mus rau AC teeb liab nrog f = f0).Yog li, LC resonant Circuit Court muaj qhov ua haujlwm ntawm kev xaiv qhov zaus thiab tuaj yeem xaiv AC teeb liab nrog qee zaus f.
