Inductor eji na ụgbọ ala

A na-eji eriri igwe na-emepụta ihe, dị ka ihe ndị bụ isi na sekit, n'ime ụgbọ ala, dị ka valvụ solenoid, moto, generators, sensọ, na modul njikwa.Ịghọta njirimara ọrụ nke coils n'ụzọ ziri ezi na-atọ ntọala siri ike maka ịmụta ụkpụrụ ọrụ nke ihe ndị a.

Ọrụ nke inductor maka njikwa ụgbọ ala switches.The inductor eji na ụgbọala bụ otu n'ime atọ dị mkpa isi akụrụngwa na sekit.

The inductors eji ụgbọ ala na-tumadi etinyere na ndị na-esonụ abụọ isi ebe: omenala electronic ngwaahịa, dị ka ụgbọ ala audio, ụgbọ ala ngwá, ụgbọ ala ọkụ, wdg Nke abụọ bụ imeziwanye nchekwa, nkwụsi ike, nkasi obi, na ntụrụndụ ngwaahịa nke ụgbọala. dịka ABS, airbags, sistemu njikwa ike, njikwa chassis, GPS, wdg.

Isi ihe mere eji eji inductors eme ihe n'ime ụgbọ ala na ụlọ ọrụ ụgbọ ala bụ n'ihi ọnọdụ siri ike na-arụ ọrụ, ịma jijiji dị elu, na oke okpomọkụ chọrọ.Ya mere, edobela ọnụ ụzọ dị elu maka ịkwado akụrụngwa eletrọnịkị ịbanye n'ụlọ ọrụ a.

Ọtụtụ ndị inductor akpaaka a na-ejikarị na ọrụ ha. Ahịa elektrọnịkị ụgbọ ala China abanyela n'oge mmepe ngwa ngwa, na-akpali agụụ maka akụrụngwa magnetik.N'ihi gburugburu ebe a na-arụ ọrụ siri ike, ịma jijiji dị elu, yana oke okpomọkụ chọrọ ụgbọ ala, ihe ndị achọrọ maka ngwaahịa akụrụngwa magnet siri ike.

Enwere ụfọdụ ụdị inductor automotive a na-ahụkarị:

1. High ugbu a inductance

Dali Electronics ewepụtala ihe inductor ụgbọ ala nwere nha 119, nke enwere ike iji ya na oke okpomọkụ nke -40 ruo +125 degrees.Mgbe itinyechara voltaji 100V DC n'etiti eriri igwe na isi magnetik maka nkeji 1, enweghị mmebi mkpuchi ma ọ bụ mmebi R50=0.5uH, 4R7=4.7uH, 100=10uH inductance value.

2. SMT ike inductance

Inductor ụgbọ ala a bụ usoro inductor CDRH, nke nwere voltaji 100V DC etinyere n'etiti eriri igwe na isi magnetik, yana nguzogide mkpuchi nke ihe karịrị 100M Ω Ụkpụrụ inductance maka 4R7=4.7uH, 100=10uH, na 101=100uH.

3. Ihe dị elu ugbu a, ndị na-emepụta ike inductance dị elu maka ụgbọ ala eletrik

Inductor ọkụ ọhụrụ ewepụtara ọhụrụ n'ahịa dabara adaba maka sistemu nkwụsị ụgbọ ala eletrik na-achọ ike ọkọnọ na nzacha dị elu ugbu a, yana ụkpụrụ inductance sitere na 6.8 ruo 470?H. Enyere ugbu a bụ 101.8A.Dali Electronics nwere ike ịnye ngwaahịa ahaziri ahazi yana ụkpụrụ inductance ahaziri maka ndị ahịa.

Site na ngwaahịa ọhụrụ ndị dị n'elu nke akụrụngwa elektrọnik magnetik akpaaka, enwere ike ịhụ na site na mgbasawanye nke ngwa multifunctional na ngwa elektrọnik, ihe ndọta na-etolite n'ebe dị elu, obere mfu, nguzogide okpomọkụ dị elu, yana ikike mgbochi mgbochi siri ike.Dali Electronics enwetala nsonaazụ nyocha dị ịrịba ama na inductor/transformers ụgbọ ala.

Nke a bụ ụfọdụ ọrụ nke inductor ike ụgbọ ala: Mmetụta mgbochi ugbu a: Ike electromotive nke na-ebute onwe ya na eriri igwe na-emegide mgbanwe dị ugbu a na eriri igwe.Enwere ike kewaa ya ka ọ bụrụ eriri mkpọkọ nke na-eme ka ọ dị elu na obere eriri mkpọkọ dị obere.

Ntugharị na ọrụ nhọrọ ugboro ugboro: Enwere ike ijikọ coils inductive na capacitors n'otu oge iji mepụta sekit nlegharị anya LC.Ọ bụrụ na ụda oscillation eke f0 nke sekit hà nhata ugboro f nke akara AC na-abụghị AC, mgbe ahụ inductance na capacitance nke sekit dịkwa nhata.Ya mere, ike electromagnetic oscillates azụ na azụ n'etiti inductance na capacitance, nke bụ resonance onu nke LC circuit.N'oge resonance, n'ihi ntụgharị ntụgharị dị n'etiti inductance na capacitance nke sekit, inductance nke ngụkọta ugbu a na sekit bụ nke kacha nta na nke ugbu a bụ nke kachasị (na-ezo aka na akara AC na f = f0).Ya mere, sekit resonant LC nwere ọrụ nke ịhọrọ ugboro ole ma nwee ike họrọ akara ngosi AC na ụfọdụ ugboro f.
