Inductor inenge yakapusa senge chikamu chemagetsi chinogona kuwana - ingori coil yewaya. Zvinoitika, zvisinei, kuti coil yewaya inogona kuita zvimwe zvinhu zvinonakidza nekuda kweiyo magineti maitiro ekoiri.

Muchikamu chino, tichadzidza zvese nezve inductors uye izvo zvavanoshandiswa.

Inductor Basics

Mumufananidzo wedunhu, inductor inoratidzwa seizvi:

Kuti unzwisise kuti inductor inogona kushanda sei mudunhu, iyi nhamba inobatsira:

Zvaunoona pano ibhatiri, girobhu remwenje, coil yewaya yakatenderedza simbi (yero) uye switch. Iyo coil yewaya inductor. Kana iwe wakaverenga Mashandiro EMagetsi Magetsi, unogona kuziva kuti inductor imagetsi.

Kana iwe waizotora inductor kunze kwedunhu iri, chaungadai uine tochi yakajairika. Iwe unovhara switch uye girobhu rinovhenekera. Ne inductor munharaunda sezvakaratidzwa, maitiro akasiyana zvachose.

Iyo girobhu yemwenje inodzivirira (kupokana kunogadzira kupisa kuita kuti filament iri mugirobhu ivheneke - ona Mashandiro Anoita Mabhururu eChiedza kuti uwane rumwe ruzivo). Waya iri mucoil ine kushomeka kwakadzikira (ingori waya), saka zvaungatarisira kana wabatidza switch ndeyekuti girobhu rivheneke zvishoma. Zvizhinji zvezvino zvinofanirwa kutevera nzira yakaderera-yekudzivirira kuburikidza nechiuno. Chii chinoitika panzvimbo ndechekuti kana iwe ukavhara switch, girobhu rinopisa zvakajeka uye rinobva radzika. Paunovhura switch, girobhu rinopisa zvakanyanya uye rinobva rabuda nekukurumidza.

Chikonzero chemaitiro aya anoshamisa ndiye inductor. Kana yazvino yatanga kuyerera mucoil, coil inoda kuvaka magineti. Panguva iyo munda uri kuvaka, iyo coil inodzivisa kuyerera kwezvino. Kana munda wavakwa, ikozvino inogona kuyerera kazhinji kuburikidza newaya. Kana switch ikavhurwa, iyo magineti yakatenderedza coil inoramba ichiyerera mukoiri kusvika munda wadonha. Iyi yazvino inoita kuti girobhu rirambe rakabatidzwa kwenguva yakati kunyangwe switch yakavhurika. Mune mamwe mazwi, inductor inogona kuchengetedza simba mumagetsi ayo, uye inductor inowanzoramba chero shanduko muhuwandu hwezvino inoyerera kuburikidza nayo.

Funga NezveMvura…

Imwe nzira yekuona kuita kweinductor ndeyekufungidzira gwara rakamanikana rine mvura inoyerera nepakati payo, uye vhiri remvura rinorema rine mapadhi aro anonyura mugwara. Fungidzira kuti mvura mumugero haisi kuyerera pakutanga.

Iye zvino unoedza kutanga mvura kuyerera. Gumbo repaddle rinoita kudzivirira kuti mvura isayerere kusvika yasvika pakumhanya nemvura. Kana iwe ukazoedza kumisa kuyerera kwemvura mumugero, vhiri remvura rinotenderera rinoedza kuchengetedza mvura kuti ifambe kusvika kumhanya kwayo kwekutenderera kunonoka kudzokera kune kumhanya kwemvura. Inductor iri kuita zvimwechete nekuyerera kwemaerekitironi muwaya - inductor inoramba shanduko mukuyerera kwemaerekitironi.

VERENGA ZVAKAWANDA

Kugona kweinductor kunodzorwa nezvinhu zvina:

Huwandu hwemakoiri - Mamwe makoiri anoreva kuwedzera inductance.

Izvo zvinhu zvinoputirwa nemakoiri (iyo musimboti)

Iyo mhiri-sectional nzvimbo yekoiri - Yakawanda nzvimbo inoreva kuwedzera inductance.

Kureba kwekoiri - Koiri pfupi inoreva nhete (kana kupindirana) makoiri, zvinoreva kuti inductance yakawanda.

Kuisa simbi mukati meiyo inductor kunopa iyo yakawanda inductance kupfuura mhepo kana chero isiri-magineti musimboti.

Iyo yakajairwa unit ye ​​inductance ndiyo henry. Iyo equation yekuverenga nhamba yehenries mune inductor ndeiyi:

H = (4 * Pi * #Inotendeuka * #Inotendeuka * Coil Area * mu) / (coil Length * 10,000,000)

Nzvimbo uye kureba kwekoiri zviri mumamita. Izwi rokuti mu ndiko kugona kwepakati. Mhepo ine mvumo ye1, ukuwo simbi inogona kunge iine 2,000.

Inductor Chishandiso: Traffic Mwenje Sensors

Ngatitii unotora coil yewaya ingangoita 6 feet (2 metres) muhupamhi, ine zvishwe zvishanu kana zvitanhatu zvewaya. Iwe unocheka mamwe magrooves mumugwagwa uye woisa coil mumakororo. Iwe unonamatira inductance mita kune coil uye ona kuti inductance yecoil chii.

Iye zvino iwe unomisa mota pamusoro pecoil uye tarisa inductance zvakare. Iyo inductance ichave yakakura zvakanyanya nekuda kwechinhu chikuru chesimbi chakaiswa mune iyo loop's magnetic field. Iyo mota yakamira pamusoro pecoil iri kuita senge musimboti weinductor, uye kuvapo kwayo kunoshandura inductance yecoil. Mazhinji ma sensors emagetsi emigwagwa anoshandisa loop nenzira iyi. Iyo sensor inogara ichiyedza inductance yechiuno mumugwagwa, uye kana inductance yasimuka inoziva kuti kune mota yakamirira!

Kazhinji unoshandisa koiri diki. Imwe huru yekushandisa inductors ndeyekuvabatanidza pamwe nema capacitor kugadzira oscillator. Ona Mashandiro Anoita Oscillators kuti uwane ruzivo.
