Ihame ryakazi rya inductance rirasobanutse cyane. Kugirango dusobanure inductance icyo aricyo, duhereye kubintu byibanze bifatika.

1. Ibintu bibiri n itegeko rimwe: magnetisme iterwa n amashanyarazi, amashanyarazi aterwa na magnetisme, n amategeko ya Lenz

1.1 Ikintu cya elegitoroniki

Hariho ubushakashatsi muri physics yishuri ryisumbuye: mugihe urushinge ruto rwa magnetiki rushyizwe kuruhande rwumuyoboro ufite icyerekezo, icyerekezo cyurushinge ruto rwa magneti rugenda rwerekana, byerekana ko hari umurima wa rukuruzi ukikije umuyaga. Iyi phenomenon yavumbuwe numuhanga mubya fiziki wo muri Danemarike Oersted mu 1820.

Niba duhinduye umuyoboro muruziga, imirima ya magneti ikorwa na buri ruziga rw'umuyoboro irashobora guhuzagurika, kandi umurima rusange wa magneti uzakomera, ushobora gukurura ibintu bito. Mu gishushanyo, coil ihabwa ingufu hamwe numuyoboro wa 2 ~ 3A. Menya ko insinga yashizwemo ifite imipaka igezweho, naho ubundi izashonga kubera ubushyuhe bwinshi.

2. Magnetoelectricity phenomenon

Mu 1831, umuhanga mu Bwongereza Faraday yavumbuye ko mugihe igice cyumuyobozi wumuzunguruko ufunze cyimutse kugirango ucike umurima wa rukuruzi, amashanyarazi azakorwa kumuyobora. Icyangombwa ni uko umuzenguruko n'umurima wa magneti biri mu bidukikije bisa naho bihinduka, bityo bikaba byitwa "dinamike" magnetoelectricity, kandi ibyuka byitwa byitwa induction.

Turashobora gukora igerageza hamwe na moteri. Muri moteri isanzwe ya DC yasunitswe, igice cya stator ni rukuruzi ihoraho naho igice cya rotor nuyobora coil. Kuzenguruka intoki rotor bivuze ko umuyobozi ugenda kugirango agabanye imirongo ya magneti. Ukoresheje oscilloscope kugirango uhuze electrode ebyiri za moteri, impinduka za voltage zirashobora gupimwa. Amashanyarazi akorwa ashingiye kuri iri hame.

3. Amategeko ya Lenz

Amategeko ya Lenz: Icyerekezo cyumuyaga uterwa no guhinduka kwa magnetiki flux nicyerekezo kirwanya ihinduka ryimikorere ya magneti.

Gusobanukirwa byoroheje kuriyi nteruro ni: iyo umurima wa magneti (umurima wa magnetiki wo hanze) wibidukikije uyobora ugenda urushaho gukomera, umurima wa rukuruzi utangwa numuyoboro wacyo utera utandukanye nu murima wa rukuruzi wo hanze, bigatuma umurego rusange wa magneti ucika intege kuruta hanze. Umwanya wa rukuruzi. Iyo umurima wa magneti (umurima wa magnetiki wo hanze) wibidukikije uyobora ugenda ucika intege, umurima wa magneti utangwa numuyoboro wacyo utera uhabanye numurima wa rukuruzi wo hanze, bigatuma umurima rusange wa magneti ukomera kuruta umurima wa rukuruzi.

Amategeko ya Lenz arashobora gukoreshwa muguhitamo icyerekezo cyumuyaga uterwa numuzunguruko.

Inductor yoroheje cyane ni coil spiral tube coil:

Ibihe mugihe cyo gukora

Twagabanije agace gato k'umuyoboro wa spiral kandi dushobora kubona ibiceri bibiri, coil A na coil B:

Mugihe cyo gukora amashanyarazi, ibintu ni ibi bikurikira:

OCoil A inyura mumashanyarazi, ukeka ko icyerekezo cyayo ari nkuko byerekanwe n'umurongo ukomeye w'ubururu, ibyo bita ibyishimo byo hanze;
Cc Dukurikije ihame rya electromagnetisme, umuyaga wibyishimo utanga ingufu zumurima wa magneti, utangira gukwirakwira mumwanya ukikije kandi utwikiriye coil B, ihwanye na coil B ikata imirongo ya magneti yingufu, nkuko bigaragazwa numurongo utudomo wubururu;
③ Dukurikije ihame rya magnetoelectricity, umuyoboro uterwa utangwa muri coil B, kandi icyerekezo cyacyo nkuko cyerekanwa numurongo wicyatsi kibisi, kinyuranye numuyoboro wo hanze ushimishije;
Cc Dukurikije amategeko ya Lenz, umurima wa rukuruzi utangwa numuyoboro uterwa ni ukurwanya umurima wa magneti wumuriro wo hanze ushimishije, nkuko bigaragazwa numurongo utudomo wicyatsi;

Ibintu nyuma yumuriro uhagaze neza (DC)

Nyuma yuko power-on ihagaze neza, ibintu byo kwishima hanze ya coil A birahoraho, kandi umurima wa magneti ubyara nabyo birahoraho. Umwanya wa magneti ntaho uhurira na coil B, kubwibyo rero nta magnetoelectricity ihari, kandi ntamwanya uhari uhagarariwe nicyatsi kibisi. Muri iki gihe, inductor ihwanye numuzunguruko mugufi wo kwishima hanze.

3. Ibiranga inductance: ikigezweho ntigishobora guhinduka gitunguranye

Nyuma yo gusobanukirwa uburyo aninductorikora, reka turebe ibintu byingenzi biranga - ikigezweho muri inductor ntishobora guhinduka gitunguranye.

Mu gishushanyo, umurongo utambitse wa axis iburyo ni igihe, na vertical axis ni iyubu kuri inductor. Mugihe icyerekezo gifunze gifatwa nkinkomoko yigihe.

Birashobora kugaragara ko: 1. Kuri ubu icyerekezo gifunze, ikigezweho kuri inductor ni 0A, bihwanye na inductor ifunguye-izunguruka. Ibi ni ukubera ko ako kanya ibintu bihinduka cyane, bizabyara amashanyarazi manini (icyatsi) kugirango arwanye imbaraga ziva hanze (ubururu);

2.Mu nzira yo kugera kumurongo uhamye, ikigezweho kuri inductor ihinduka kuburyo bugaragara;

3. Nyuma yo kugera kumiterere ihamye, ikigezweho kuri inductor ni I = E / R, bihwanye na inductor iba izunguruka mugihe gito;

4. Guhuza numuyoboro uterwa ningufu zatewe na electromotive power, ikora kugirango irwanye E, bityo yitwa Back EMF (rever electromotive force);

4. Inductance ni iki?

Inductance ikoreshwa mugusobanura ubushobozi bwigikoresho cyo kurwanya impinduka zubu. Nubushobozi bukomeye bwo kurwanya impinduka zubu, niko inductance, nibindi.

Kubyishimo bya DC, inductor amaherezo iba mumashanyarazi magufi (voltage ni 0). Ariko, mugihe cyamashanyarazi, inzira na voltage ntabwo 0, bivuze ko hariho imbaraga. Inzira yo kwegeranya izo mbaraga yitwa kwishyuza. Irabika izo mbaraga muburyo bwa magnetique kandi ikarekura ingufu mugihe gikenewe (nkigihe umunezero wo hanze udashobora kugumana ubunini buriho muburyo butajegajega).

Inductors ni ibikoresho bidafite imbaraga mumashanyarazi. Ibikoresho bidafite imbaraga ntibikunda impinduka, kimwe na flawheels muri dinamike. Biragoye gutangira kuzunguruka mbere, kandi nibatangira kuzunguruka, biragoye guhagarara. Inzira yose iherekejwe no guhindura ingufu.
