Thermosetting yas pob electromagnetic coil QVT306

Dab tsi yog cov yam ntxwv ntawm inductance parameter?

1. Cov yam ntxwv zoo:

Qhov zoo tshaj plaws Q yog qhov tseem ceeb siv los ntsuas qhov kev sib raug zoo ntawm lub zog khaws cia los ntawm cov khoom siv hluav taws xob (inductors lossis capacitors) thiab lawv lub zog noj, uas tau hais tias: Q = 2π siab tshaj plaws khaws cia lub zog / lub zog poob txhua lub lim tiam. Feem ntau hais lus, qhov loj dua Q tus nqi ntawm inductance coil, qhov zoo dua, tab sis loj heev yuav ua rau kev ruaj ntseg ntawm kev ua hauj lwm Circuit Court tsis zoo.

2, Inductance:

Thaum cov tam sim no nyob rau hauv ib lub coil hloov, lub sib nqus flux dhau los ntawm lub kauj voj nws tus kheej los ntawm cov hloov tam sim no kuj hloov, ua rau lub kauj nws tus kheej induce electromotive quab yuam. Tus kheej inductance coefficient yog lub cev muaj nuj nqis uas sawv cev rau tus kheej inductance peev xwm ntawm lub kauj. Nws tseem hu ua tus kheej inductance lossis inductance. Nws yog qhia los ntawm L. Noj Henry (H) raws li chav tsev, ib txhiab ntawm nws hu ua millihenh (mH), ib lab hu ua millihenh (H), thiab ib txhiab ntawm nws hu ua Nahen (NH).

3. DC Resistance (DCR):

Hauv kev npaj inductance, qhov me me ntawm DC tsis kam, qhov zoo dua. Lub ntsuas ntsuas yog ohm, uas feem ntau yog cim los ntawm nws tus nqi siab tshaj plaws.

4, Tus kheej-resonant zaus:

Inductor tsis yog cov khoom siv inductive nkaus xwb, tab sis kuj muaj qhov hnyav ntawm kev faib tawm. Lub resonance ntawm ib tug ntau zaus tshwm sim los ntawm inductance inductance thiab faib capacitance ntawm inductor nws tus kheej yog hu ua self-harmonic zaus, los yog hu ua resonance zaus. Qhia hauv SRF, chav tsev yog megahertz (MHz).

5. Tus nqi impedance:

Tus nqi impedance ntawm ib qho inductor yog hais txog qhov sib npaug ntawm tag nrho nws cov impedances nyob rau hauv tam sim no (tus naj npawb nyuaj), suav nrog kev sib txuas lus thiab DC qhov chaw. Tus nqi impedance ntawm DC ib feem yog tsuas yog DC tsis kam ntawm winding (qhov tiag), thiab tus nqi impedance ntawm qhov kev sib txuas lus suav nrog cov reactance (xav txog ib feem) ntawm inductor. Hauv qhov kev nkag siab no, tus inductor tuaj yeem suav tias yog "kev sib txuas lus tiv thaiv". 6. Rated tam sim no: Qhov kev siv DC txuas ntxiv uas tuaj yeem dhau los ntawm tus inductor tau tso cai. DC tam sim no siv yog nyob ntawm qhov kub siab tshaj plaws ntawm qhov inductor nyob rau hauv qhov siab tshaj plaws ambient kub. Qhov ntxiv tam sim no muaj feem xyuam rau lub peev xwm ntawm inductor los txo qhov poob ntawm winding los ntawm qis DC tsis kam, thiab kuj muaj feem xyuam rau lub peev xwm ntawm inductor kom dissipate poob ntawm winding zog. Yog li, qhov ntxiv tam sim no tuaj yeem txhim kho los ntawm kev txo qhov DC tsis kam lossis nce qhov ntsuas inductance. Rau tsawg zaus tam sim no waveforms, nws lub hauv paus txhais tau tias square tam sim no tus nqi
