Omenala inductor na-agwa gị

Kedu usoro iji mgbanaka magnetik inductive ? Kedu ihe dị iche n'etiti ihe mgbanaka magnetik dị iche iche? Ka anyị mara ya ọnụ.

Mgbanaka magnetik bụ ihe a na-ejikarị eme ihe na-egbochi nnyonye anya na sekit eletrọnịkị, nke na-enwe mmetụta nkwụsị nke ọma na ụzụ dị elu, nke kwekọrọ na nzacha dị ala. Ọ nwere ike idozi nsogbu ahụ nke ọma na nkwụsịtụ nnyonye anya dị elu nke eriri ọkụ, akara akara na njikọ njikọ, ma nwee usoro uru, dị ka mfe iji, dị mfe, dị irè, obere oghere na ihe ndị ọzọ. Iji isi mgbochi nnyonye anya ferrite iji kwụsị nnyonye anya electromagnetic (EMI) bụ usoro akụ na ụba, dị mfe ma dị irè. A na-eji ya eme ihe na kọmpụta na ngwá electronic ndị ọzọ.

Ferrite bụ ụdị ferrite nke a na-akwado site na iji ihe ndọta dị elu iji banye otu ma ọ bụ karịa magnesium, zinc, nickel na ọla ndị ọzọ na 2000 ℃. N'ime obere bandwit dị ala, ihe mgbochi magnetik na-egbochi nnyonye anya na-egosi ihe mgbochi inductive dị ala na ọ dịghị emetụta nnyefe nke akara bara uru na ahịrị data ma ọ bụ akara ngosi. N'ime eriri ugboro dị elu, malite na 10MHz, mgbochi ahụ na-abawanye, ma akụkụ inductance na-anọgide na-adị ntakịrị, ma ihe mgbochi na-abawanye ngwa ngwa. mgbe enwere ike ugboro ugboro na-agafe na ihe ndọta, ihe mgbochi ahụ ga-agbanwe ike ndị a n'ime ike ọkụ ọkụ. N'ụzọ dị otú a, a na-arụ ihe nzacha dị ala, nke nwere ike ime ka ụda mkpọtụ ụda dị elu dị elu, ma enwere ike ileghara ihe mgbochi na mgbaàmà bara uru nke dị ala anya ma ghara imetụta ọrụ nkịtị nke sekit. .

Otu esi eji mgbanaka magnetik nke inductance mgbochi nnyonye anya:

1. Tinye ya ozugbo na ọkụ ọkụ ma ọ bụ ụyọkọ akara akara. Ka iwelie nnyonye anya ma nweta ume, ị nwere ike gbaa ya gburugburu ọtụtụ ugboro ugboro ugboro.

2. Mgbanaka magnetik na-egbochi jamming na-arị elu clip dabara adaba maka nkwụsị mgbochi jaming akwụ ụgwọ.

3. Enwere ike ijide ya ngwa ngwa na eriri ọkụ na akara mgbaàmà.

4. Nrụnye na-agbanwe agbanwe na reusable.

5. A na-edozi ụdị kaadị nke nwere onwe ya, nke na-adịghị emetụta ihe oyiyi zuru ezu nke akụrụngwa.

Ọdịiche dị n'etiti ihe dị iche iche nke inductance magnetik mgbanaka

Agba nke mgbanaka magnetik bụ n'ozuzu eke-oji, na elu nke magnetik mgbanaka nwere ezi ahụ, n'ihi na ọtụtụ n'ime ha na-eji mgbochi nnyonye anya, n'ihi ya, a na-adịkarịghị agba akwụkwọ ndụ akwụkwọ ndụ. N'ezie, a na-ejikwa obere akụkụ ya na-emepụta inductors, a na-efesakwa ya akwụkwọ ndụ akwụkwọ ndụ ka o wee nweta ihe mkpuchi dị mma ma zere imerụ waya enamelled dị ka o kwere mee. Agba n'onwe ya enweghị ihe jikọrọ ya na arụmọrụ. Ọtụtụ ndị ọrụ na-ajụkarị, otu esi amata ọdịiche dị n'etiti mgbanaka magnetik na-adịkarị elu na mgbanaka magnetik na-adịkarị ala? N'ozuzu, mgbanaka magnetik na-adịkarị ala bụ akwụkwọ ndụ akwụkwọ ndụ na mgbanaka magnetik dị elu bụ ihe okike.

A na-atụ anya na ikike μ I na resistivity ρ dị elu, ebe mmanye Hc na ọnwụ PC dị ala. Dị ka ojiji dị iche iche si dị, e nwere ihe dị iche iche chọrọ maka Curie okpomọkụ, okpomọkụ kwụsie ike, permeability mbelata ọnụọgụ na kpọmkwem ọnwụ ọnụọgụ.

Nsonaazụ bụ isi bụ ndị a:

(1) Manganese-zinc ferrite na-ekewa n'ime nnukwu permeability ferrite na elu-frequency ala ike ferrite (nke a makwaara dị ka ike ferrite). Ihe e ji mara nke elu permeability mn-Zn ferrite bụ nnọọ elu permeability.

N'ikwu okwu n'ozuzu, ihe ndị nwere μ I ≥ 5000 bụ ihe a na-akpọ ihe ndị dị elu, na μ I ≥ 12000 na-achọkarị.

Mn-Zn ferrite dị elu na obere ike, nke a makwaara dị ka ferrite ike, na-eji ihe ferrite ike. ihe ndị a chọrọ ịrụ ọrụ bụ: ikike dị elu (nke a na-achọkarị μ I ≥ 2000), okpomọkụ Curie dị elu, njupụta dị elu, elu saturation magnetik induction induction intensity na magnetik isi ọnwụ na obere ugboro.

(2) Ni-Zn ferrite ihe, na obere oge dị n'okpuru 1MHz, arụmọrụ nke NiZn ferrite adịghị mma dị ka nke usoro MnZn, ma n'elu 1MHz, n'ihi nnukwu porosity na elu resistivity, ọ dị mma karịa. Sistemụ MnZn ka ọ bụrụ ezigbo ihe ndọta dị nro na ngwa ugboro dị elu. The resistivity ρ dị elu dị ka 108 ω m na elu ugboro ọnwụ bụ obere, ya mere, ọ na-adabara karịsịa maka elu ugboro 1MHz na 300MHz, na Curie okpomọkụ nke NiZn ihe dị elu karịa MnZn, Bs na ruo 0.5T 10A / m HC nwere ike ịdị obere ka 10A / m, ya mere ọ dị mma maka ụdị inductor dị iche iche, ndị na-agbanwe agbanwe, eriri nzacha na mkpuchi mkpuchi. Ni-Zn elu-ugboro ferrite nwere bandwit sara mbara na obere nnyefe mfu, ya mere a na-ejikarị ha dị ka nnyonye anya electromagnetic (EMI) na redio nnyonye anya (RFI) cores maka mwekota nke elu ugboro electromagnetic nnyonye anya (EMI) na elu ugwu ngwaọrụ. Ike ugboro ugboro na mgbochi nnyonye anya. Enwere ike iji Ni-Zn ike ferrite dị ka ngwaọrụ brọdband nke RF iji ghọta nnyefe ike na ngbanwe nke ngbanwe nke akara RF n'ọtụtụ buru ibu, yana oke ugboro ole dị ala nke ọtụtụ kilohertz yana oke ugboro ugboro nke puku megahertz. Ihe Ni-Zn ferrite nke eji na DC-DC ntụgharị nwere ike ịbawanye ugboro nke ọkụ na-agbanwe ma na-ebelata olu na ịdị arọ nke ihe ngbanwe eletrọnịkị.

Mgbanaka magnetik a na-ahụkarị - enwere ụdị mgbanaka magnetik abụọ na ahịrị njikọ izugbe, otu bụ nickel-zinc ferrite magnetik, nke ọzọ bụ mgbanaka magnetik-zinc ferrite, ha na-arụ ọrụ dị iche iche.

Mn-Zn ferrite nwere njirimara nke ịdị elu dị elu na njupụta dị elu, ma nwee njirimara nke ọnwụ dị ala mgbe ugboro ole dị ala karịa 1MHz.

Ihe dị n'elu bụ mmalite nke inductor mgbanaka magnetik, ọ bụrụ na ịchọrọ ịmatakwu banyere inductor, biko nweere onwe gị ịkpọtụrụ anyị.
