Bottom ea kela ho

A bohlokoa haholo e sebetsang boleloang ke taba e khethehileng ea motlakase ketsahalo induction, bitsoa intša bottom. Kahoo, ha ho kela induction bopa ya jwale, ka nako eo ka nako le eona hlaha le ts'ebetsong a khoheli a leng eketsa le ho eketseha hona joale. Le fetola a khoheli a kela ts'ebetsong bitsang electromotive lebotho la (EMF), e leng tekanyo e lekanang ya ho khoheli ts'ebetsong lebelo phetoho.

Ho tloha ka tabeng ena mokhanni bitsang matla electromotive ka boeona, e bitsoa ho intša induction. Lipono tse makatsang tsa ho intša bottom ka lipotoloho tsa motlakase ka linako tse ling bapisoa le ponahatso ea inertia ka nyenyenyane.

Lebotho electromotive hlohlelletsoa ka kela induction tlas'a tšusumetso ea liphetoho tsa matla a khoheli ea eona ts'ebetsong o bitsoa intša induction electromotive sebetse.

Ho ea ka molao Lenz e, ka nako ya kgolo ya kaofela a khoheli a ts'ebetsong o ne o salla ho kela windings, ba ikhopolang ho hlohlelletsoa EMF ka kela e lebisitsoe ho electromotive lebotho la mohloding, e kenyelelitsoe oa potoloho ena 'me o hanyetsa le ho eketseha ha jwale ka oa potoloho ea kela.

Ha jwale ka kela ho fihla boleng kamehla le ts'ebetsong a khoheli a kgaotsa ho fetola, 'me ho intša susumetsoa EMF ka kela ho fetoha lefela.
Le ba ikhopolang ho induction, joalokaha e etsahala thulaganyou e 'ngoe ea induction motlakase, hlohlelletsoa electromotive lebotho la ke tekanyo e lekanang ya ho lebelo ka seo ts'ebetsong a khoheli a amahanngoa le balebeli ba potoloho ka tse phallang jwale, e fetotsoe. The boholo ba ts'ebetsong a khoheli a ka ho ba sieo ha ea tšepe ka kela tekanyo e lekanang ya ho lebelo leo liphetoho jwale (ΔI / Δt), generating ho phalla.

Kahoo, boholo ba matla a electromotive ho intša induction hore hlaha mokhanni ke tekanyo e lekanang ya ho lebelo leo liphetoho hona joale ho eona.
Haeba u nka lithapo tsa dibopeho tse sa tšoaneng, e fellang kateng le hore ho ba le tekanyo e tšoanang ea phetoho ea morao-rao, electromotive matla a ho intša induction, ho fellang ka tsona ho tla ba ba fapaneng.

Kahoo, haeba re nka kela le ea ntan'o ba ho otlolla le eena a le mong, ka nako eo ka tekanyo e tšoanang moo ba phetoho jwale etsahala, ba ikhopolang ho induction electromotive matla a kela ho tla ba le nako e telele. Sena ke ka ntlha ya go ha e le hantle hore e mong le e matla a mola prinizyvaya kela chenchana, ho kopanela le palo e khōloanyane ea makhetlo a ho feta a sekgoqetsane le 'ngoe.

Lenane, e tsebahala ka kamano e teng pakeng lebelo le eo hona joale fapana ka ketane, 'me sena hlaha intša induction EMF - bottom potoloho.

Tlohelang bottom ea kela ke lengolo L; ha a ntse a ho itšetleha ba lebotho electromotive ea sekhahla intša induction eo hona joale e fetohile ka ho bontšoa ke tsela eo e latelang:

E = - L (ΔI / Δt)

mona

appa L = (ed.E ˖ diyuniti. T) / (ed.I)

A nka hore ka moralo ona, Δt = 1 bobeli, ΔI = E 1 ampere le volt = 1, re fumana:

appa L = 1 (ka ˖ set lao / hantle)

unit trust ena o bitsoa Henry (H).

Ka hona,

1 unami = 1 (ka ˖ set lao / hantle)

Kahoo Henry - ke bottom ea kela, e leng phetoho ea morao-rao ea 1 ampere ka bobeli excites ea ho intša induction electromotive lebotho la lekana le 1 volt.
Bakeng sa ho lekanya inductances nyane sebediswa thousandths la Henry - MH (MH) kapa millionths la Henry - uH (uH).

Ho phaella moo, hangata a sebelisa, 'me tse ling tse unit trust - disentimitara bottom, ka 1 cm, = 1000 uH inductor.

Kahoo,

1 MH Mr = 1000 = 1.000.000 = 1.000.000.000 uH cm,

The bottom ea kela ke itšetlehile ka palo ea eona ea chenchana, sebopeho le boholo. E khōlō palo ea ba chenchana ka kela ho intša bottom, e khōlō bottom lona.

Hape, ba ikhopolang ho bottom, ea kela bottom eketseha haholo ha kenyelletsa hore e be ea mantlha ea tšepe kapa tse ling tse leha e le efe lintho tse bonahalang a khoheli a.
Large bottom electromagnets na windings ka lijenereithara le Motors, balebeli ba potoloho bulehileng ka nako eo ha tekanyo ea phetoho ea motlakase hona joale (ΔI / Δt) ke phahameng haholo ka windings tsena ka 'na ba moholo ho intša induction electromotive lebotho la eo, haeba e se qoba, o tla etsa hore ho sithabela matsoelintsoeke e kwahelang.
