The circuit saddex waji

nidaamka ugu weyn ee hadda la ansixiyay hadda guud waa saddex waji wareeggeedii, kaas oo ay leeyihiin dhowr faa'iidooyin ka badan hal waji.

Saddex-waji nidaamka hadda loo yaqaan hadda saddex waji ee ay saddex Ciidamada electromotive isagoo Ilodanimada inayan isku mid ah iyo inta jeer laakiin wareejiyay si ixtiraam leh in midba midka kale in wajiga by 120⁰ ama inta lagu guda jiro muddo markii saddexaad.

circuit kasta oo kala duwan, nidaamka sida saddex waji leh oo la sheegay in la yareeyo wajiga.

Wajiga hadda, oo waxaa lagu fuliyaa circuit saddex waji laga heli karaa by isku seddex ka mid ah matoor la mid ah, siinta a-hal waji talantaalli hadda, rotors, oo dhammaantood ku yaal meel go'an, waxaa dhab ah ku lifaaqan kasta oo kale oo ma beddeli ay xilalkaasi wareeg. In matoor this windings stator waxaa biloowday midba midka kale by 120⁰ kooxda rotor ah. Under xaaladaha sida, waa arrin iska cad in ciidanka electromotive of matoor labaad Hadhi doono isbedel ay la xiriirta matoor ugu horeysay on 120⁰, ie Qiimaha ugu sareeya ee ciidamada electromotive ah oo isku jiho ah in matoor labaad ka dib waxaa imaan dhan rotor matoor ku 120⁰ celin doonaa. Ciidamada electromotive sidoo kale ka mid ah matoor saddexaad daahi doono qaraabo in matoor labaad 120⁰.

Laakiin hab ka mid ah soo saara hadda, kuwaas oo circuit saddex waji oo kale, ma aha dhaqaale oo macne iyo farsamo adag. Inta badan ka sahlan in saddex windings stator ku xiran yihiin in xirmo hal. matoor noocan oo kale ah waxaa lagu magacaabaa marxaladda matoor hadda.

Sayidka, stator ku alternator hadda waxay leedahay saddex windings (yeedhay weji matoor), at 120⁰ qaraabo barakacay in ay midba midka kale. rotor waa matoor saddex waji leh oo hadda la rotor ah qaab isku mid matoor AC-hal waji.

Inta lagu jiro wareeg ah windings rotor oo dhan waa la abuuray siman inta jeer iyo Ilodanimada inayan ciidanka electromotive, laakiin waxa ay isku mar ma gaaraan ugu badnaan. Haddii loo maleeyo in ciidanka ugu badan electromotive ahbaa waqtiga marinka ee xarunta of cirif woqooyi ee rotor ee bilowga loogu fuuli jiray, waa ay fududahay si aad u aragto in ciidanka ugu badan electromotive ah oo isku jiho ah in gariiradda labaad ka dib wareeg ee rotor waxay u iman doontaa on 120⁰, iyo kii saddexaad - ka dib markii u jeestay on 240⁰ qaraabo hore.

Ku xiridda in circuit dibadda matoor marxalad kasta, waxaan u hesho circuit hadda saddex waji lahayn isku xidhan jirin xiriir korontada, kuna waari dhexdeeda kasta hadda circuit goonida ka mid ah ay iska caabin noqon doonaa siman ee Ilodanimada inayan laakiin wareejiyay in qaraabo waji kasta oo ay sidoo kale kale ee 120⁰.

In ay ku xidhmaan matoor noocan oo kale ah si wareeg ah oo dibada, u baahan tahay lix fiilooyin. Si loo yareeyo tirada fiilooyin kuwa u taga inay circuit dibadda, waxaa lagama maarmaan ah in ay ku xidhmaan gariiradda aqbalana iyo matoor isku xidhan si ay u sameeyaan koronto ku xidhay in nidaamka saddex wajiga. xiriir Taas waxaa la samayn karaa laba siyood oo kala duwan: saddex xagalka ah iyo xiddig.

Labada xeryahooda ka dhigi suurto gal ah si loo badbaadiyo waxyaabaha in la isugu gudbiyo ee awoodda la mid ah saddex matoorrada saddex waji oo madax banaan.

wareeggeedii saddex waji ka dhigtay in ay suurto gal ah in la abuuro fudud ah oo ku haboon qalabka ay ku shaqeeyaan baabuurta korontada, oo la yidhaahdo asynchronous. Isaga oo qalab ku salaysan codsiga duurka magnetic ku qoqobada. In kiiska ugu fudud, beer magnetic waxaa laga heli karaa by qoqobada magnet kabo faras ah.

Haddii beerta la dhigayaa in qoqobada kaari xidhan, oo waxaa ku xidhnaa in dhidibka, duurka ku magnetic in wareeg intersecting ay kaari circuit dhinac u abaari doonaa ciidamo electromotive dhexdeeda induction in abuuraa hadda induction ah in loop this u xiran yihiin. Tani lalana hadda isaga iyo berrinkaba inuu magnetic of gariiradda magnet qoqobada isku shaandheyn doonaa. jirsado jihada wareeg waxaa lagu go'aamiyaa iyadoo la isticmaalayo xukunka gacanta bidix.

Saddex matoorrada wajiga ka kooban yihiin laba qaybood: qaybta ku noqnoqosho leh - rotor iyo taagan ah - stator ah.

qoqobada The field magnetic ahbaa in engine ma aha by wareeg farsamo oo ka mid ah ulaha magnetic, iyo socodka ah ee talantaalli ah hadda windings stator go'an wajiga.

wareeggeedii saddex waji ayaa loogu talagalay by mid ka mid ah injineerada weyn korontada oo ka mid ah XIX iyo qarnigii XX hore. - Injineer Ruush MO Dolivo-Dobrovolsky (1862-1919). Nidaamkan ayaa fursado wayn furay si loogu isticmaalo warshadaha korontada. Waxaa ugu muhiimsan waa:

• kaydka in line taararka xira saldhigga in macaamilka;
• macquul ah qoqobada field magnetic codsatay in matoorrada saddex waji.
