Talantaalli ah hadda korontada

Talantaalli ah qulqul koranto - hadda la jihada waqti kala duwan ah iyo xoog. hadda kuwa kala duwan yihiin oo kaliya in size, loo yaqaan gaboowday. In warshadaha iyo maalin walba nolosha waxaa inta badan la isticmaalo talantaalli hadda sinusoidal.

Diinta DC si AC korontada la samayn karaa sida soo socota. La saaray in gariiradda direyska guurto ah magnetic field of silig. Iyada oo wareeg uniform of gariiradda ku saabsan dhidibka of daadanayo magnetic si joogto ah u kala duwan yihiin baaxadda iyo jihada. Sidaas awgeed, by sharciga induction electromagnetic, gariiradda la aasaasay variable jihada iyo baaxadda ciidanka electromotive (EMF). Haddii gariiradda noocan oo kale ah ku xiran circuit dibadda, ka dibna waxa aan ka heli qulqul koranto ah talantaalli ah.

Marka diyaarada ee gariiradda qoqobada noqdo dadab la eego khadadka duurka duurka magnetic marayay therethrough ka daadanayo magnetic - (Φ = Φmax) ugu weyn, xawaaraha isbedelka ay eber (ΔΦ / Δt = 0), sida marayay meel hanuuniyo warqada kacaanka oo ka mid ah khadadka xoog, iyaga oo aan soo gudbaya. Sidaa awgeed, induction ciidanka electromotive sameeyay gariiradda uu noqdo eber (E = 0).

Marka diyaarad gariiradda la siman yahay khadadka xoog, ka daadanayo waxa ay cabaar, waa loo siman yahay si eber (Φ = 0), heerka isbedelka ee ay ugu badnaan ku meel this ((ΔΦ / Δt) max), tan iyo kirishbooyada gariiradda u guurayso dadab iyo in ay khadadka xoog.

ciidanka Electromotive timi kiiskan in loop ka, ayaa qiimaha ugu badnaan (E = Emax). Marka wareeg dheeraad ah oo loogu fuuli jiray xawaaraha isbedel aan istaagayn cabaar gariiradda kordhin doonaa; Sidaa darteed, EMF in qiimaha buuxda u kordhin doonaa 0 ilaa Emax. Sayidka, heerka emf ku laaluusheen in gariiradda qoqobada per kacaanka badala ka -Emax in + Emax.

Us silig gariiradda furan oo ku lifaaq oscilloscope ah. Marka gariiradda isku bedbedeli doono duurka a magnetic, oscilloscope ah u qoraan doonaa oo dhan isbeddel hadda, kaas oo lagu xukumi doonaa, oo isbedelka ciidamada electromotive in gariiradda inta lagu jiro mid ka mid ah kacaanka.

hadda The ahbaa in gariiradda inta ay daaweynta uniform duurka direyska magnetic, sida lagu muujiyey by waveform sinusoidally kala duwan. hadda Tan waxaa lagu magacaabaa talantaalli sinusoidal.

Muddada waqtiga loogu talagalay taas oo ciidanka electromotive qabata mid oscillation, loo yaqaan muddada AC ah.

muddo oscillation naqshada Letter - T. Tirada oscillations halkii 1 labaad - inta jeer ee hadda, kaas oo loogu tala galay warqad f ah. Its unit oo ah qiyaas - Hertz (Hz):

f = 1 / T, ama T = 1 / f.

Haddii qiimaha EMF waqti aan sabab qaar ka mid ah waxaa muujinaysaa by e (miraheeda degdeg ah), iyo qiimaha ugu weyn (peak) - iyada oo Emax ah, waqtiga sharciga ku muujiyey tiirsanaanta yahay, waqti, lagu sheegi karaa sida hadal soo socda in ay dhacdo ah ee hadda sinusoidal:

e = Emax˖sin (2 / T) t.

Inta badan wadamada, isticmaalka warshadaha iyo la deggan yahay talantaalli hadda korontada la soo noqnoqoshada ah 50 Hz, muddada muddada 0.02 labaad.

Diyaarinta hadda talantaalli korontada ka tamarta si farsamaysan loo sameeyaa by yahay mashiinno gaar ah, kuwaas oo loo yaqaan matoorrada. Mabda'a ah shaqadooda - sharciga induction electromagnetic. The circuit oscillator ugu fudud matali karaa sida jir ah qoqobada agagaarka dhidibka duurka a magnetic of electromagnet ama magnet joogto ah. Marka aad isku shaandheyn ku yiilleen sameeyay ciidanka variable electromotive waxa ku jira. By xira jir si wareeg ah oo dibada, waxaan ka heli qulqul koranto ah talantaalli ah. alternator An isagoo nidaam magnetic taagan iyo gariiradda qoqobada qabsiyada dhisay.

Ku dhowaad dhammaan of windings matoorka (barroosinka) ayaa lagu wadaa taagan iyo nidaamka magnetka (inductor) waxaa wareejiyo. qayb aan dhaqaaqayn ee matoorka waxaa lagu magacaabaa stator ah, iyo dhaqaajin karo - rotor.
