Electromagnetic coil yerori ABS inodzora vharafu 4721950520

Common coil

1. Single layer coil

Single-layer coil inomonerwa papepa chubhu kana bakelite skeleton ine insulated waya imwe neimwe. Zvakadai sewave antenna coil mune transistor radio.

2. Muzinga wehuchi

Kana ndege yekoiri yeronda isina kufambirana nenzvimbo inotenderera, asi ikapindirana pane imwe kona, rudzi urwu rwekoiri inodaidzwa kuti coil yehuchi. Uye nhamba yenguva iyo waya inokotama ichidzoka shure kana ichitenderera kamwe chete, iyo inowanzonzi nhamba yekupeta. Huchi inomonereka nzira ine zvakanakira vhoriyamu diki, diki yakagoverwa capacitance uye hombe inductance. Mizinga yehuchi inomonerwa nemuchina wekumonereka nemuzinga. Iyo yakanyanya kupeta mapoinzi, idiki iyo yakagoverwa capacitance.

3. Ferrite core uye iron powder core coil

Iyo inductance yecoil ine hukama nekuti kune magineti musimboti kana kwete. Kupinza ferrite musimboti mumhepo-core coil kunogona kuwedzera inductance uye kunatsiridza coil mhando.

4, coil yemhangura

Copper core coil inoshandiswa zvakanyanya mu ultrashort wave range. Zviri nyore uye zvakasimba kushandura inductance nekutenderedza nzvimbo yemhangura musimboti mune coil.

5, color code inductor

Rudzi-coded inductor inductor ine yakagadziriswa inductance, uye inductance yayo inotaridzwa nemhete yemavara senge inopikisa.

6, kukachidza coil

Iyo coil inorambidza kufamba kwealternating current inonzi choke coil, inogona kupatsanurwa kuita high-frequency choke coil uye low-frequency choke coil.

7. Deflection coil

Deflection coil mutoro weiyo inobuda nhanho yeTV scanning wedunhu. Deflection coil inoda yakakwira deflection sensitivity, yunifomu magineti, yakakwira Q kukosha, saizi diki uye mutengo wakaderera.

Choke chiito

Iyo yega-induced electromotive simba mune coil ye inductance coil inogara ichipesana nekuchinja kwazvino mucoil. Iyo inductance coil ine inovharira mhedzisiro pa AC ikozvino, uye saizi yekuvharisa iyo inonzi inductance xl, uye iyo unit ndeye ohm. Hukama hwayo ne inductance L uye AC frequency F ndeye xl = 2πfl. Inductors inogona kunyanya kukamurwa kuita yakakwira-frequency choke coils uye yakaderera-frequency kukachidza makoiri.

Tuning uye frequency sarudzo

Iyo lc tuning yedunhu inogona kuumbwa nekubatanidza inductance coil uye capacitor mukuwirirana. Kureva kuti, yakasikwa oscillation frequency f0 yedunhu yakaenzana nefrequency f yeiyo isiri-inochinjisa chiratidzo, saka inductive reactance uye capacitive reactance yedunhu zvakare yakaenzana, saka iyo electromagnetic simba oscillates kumashure nekudzoka mune inductance uye. capacitance, inova resonance phenomenon yelc circuit. Pa resonance, iyo inductive reactance uye capacitive reactance yedunhu yakaenzana uye yakatarisana, uye inductive reactance yeiyo yakazara loop ikozvino idiki uye yazvino ndiyo yakakura (ichireva iyo AC chiratidzo ne f = "F0"). lc resonant circuit ine basa rekusarudza frequency, iyo inogona kusarudza iyo AC chiratidzo neimwe
