Waa maxay sababta matoorka asynchronous
Sababtoo ah hadda soo jiidashada ee gariiradda rotor ee matoor asynchronous saddex-waji ah ayaa la soo saaray iyadoo ay ugu wacan tahay dhaqdhaqaaqa qaraabada ah ee u dhexeeya kaareeyaha rotor iyo goobta magnetic. Xawaaraha rotor-ka ee mooto asynchronous saddex-waji ah laguma wada shaqayn doono goobta magnetic-wareega ah, kama badnaan doono xawaaraha goobta magnetic-wareega ah. Haddii xawaaraha wareega ee rotor ee matoor saddex-waji ah asynchronous motor uu la mid yahay xawaaraha wareega ee goobta magnetic wareegta ah, ma jiri doono wax qaraabo ah oo u dhexeeya field magnetic iyo rotor, iyo kaari ma gooyn karo xariiqda magnetic ee xoogga. , sidaa darteed awoodda korantada ee la kiciyay iyo hadda laguma dhalin doono gariiradda rotor-ka, kaariyaha rotor-ka ee matoorka asynchronous ee saddexda weji ma saameyn doono xoogga korantada ee goobta magnetic si uu rotor-ku wareego. Sidaa darteed, xawaaraha wareega rotor ee matoorka asynchronous saddex-waji ah ma noqon karo mid la mid ah kan goobta magnetic wareegta ah, oo had iyo jeer waa ka yar yahay xawaaraha isku midka ah ee goobta magnetic wareeg ah. Si kastaba ha ahaatee, marka la eego qaabka hawlgalka gaarka ah (sida bareegga curinta korantada), xawaaraha rotor ee matoorka asynchronous ee saddexda weji wuxuu ka weynaan karaa xawaaraha isku midka ah.
Wareegga mooto asynchronous saddex waji
Summetrical 3-waji dabaysha waxa ay ku xidhan tahay 3-weji xaadirka simmetrical si loo dhaliyo goob birlabeed ah oo wareegta. Siliga magnetic field wuxuu gooyaa dabaylaha rotor-ka. Marka loo eego mabda'a soo-saarka korantada, e iyo anigu waxaan ku abuurnaa dabaylaha rotor-ka. Wareegga rotor-ka waxaa saameeya xoogga korantada ee goobta magnetic, taas oo ah, wareegga korantada ayaa la soo saaray si uu rotorku wareego. Rotor-ku waxa uu soo saaraa tamar makaanik waxa uuna kaxeeyaa culayska makaanikada si uu u wareego.
Matoorka AC, marka dabaylaha stator uu dhex maro AC hadda, xoogga magnetomotive cufan ayaa la aasaasay, kaas oo saameyn weyn ku leh beddelka tamarta iyo waxqabadka hawlgalka matoorka. Sidaa darteed, dabaysha saddex-waji AC waxay ku xidhan tahay saddex-waji AC si ay u abuurto xoog magnetomotive ah, kaas oo loo kala qaybin karo laba xoog oo magnetomotive ah oo wareeg ah oo leh baaxad siman iyo xawaare ka soo horjeeda, si loo sameeyo hore iyo dib u rogida beeraha magnetic ee farqiga hawada. Labadan goobood ee birlabeedka ah ee wareegaya ayaa gooyay kaariyaha rotor-ka oo ay dhaliyaan xoog koronto oo la kiciyay iyo soo jiidashada hadda ee kaariyaha rotor siday u kala horreeyaan.
Hadda waxa uu la falgalaa goobta magnetic si uu u soo saaro togan iyo togan korantada. Qulqulka korantada ee hore waxa uu isku dayaa in uu rotor-ku hore u wareego; Wareegga korantada ee gadaale wuxuu isku dayaa inuu rotor-ka rogo.

Matoorka firfircoonida ee DC wuxuu leeyahay laba dabaylo kicin, kicin is barbar socda iyo kicin taxane ah, fiilooyinka ayaa lagu muujiyay shaxanka (d). Haddii qulqulka birlabeedka ka dhasha dabaylaha kicinta ee taxanaha ah iyo dabaylaha kicinta barbar socda ay leeyihiin jiho isku mid ah, waxa loo yaqaan kicinta iskudhafka ah. Haddii laba qulqulo magnetic leeyihiin jiho iska soo horjeeda, waxa loo yaqaan excitation ka kooban kala duwan.
Matoorada DC ee leh hababka kicinta ee kala duwan waxay leeyihiin sifooyin kala duwan. Guud ahaan, hababka kicinta ugu weyn ee matoorka DC ayaa ah kicinta barbar socota, kicinta taxanaha ah iyo kicinta isku dhafan.

Astaamaha matoorka DC
(1) Waxqabadka habaynta xawaaraha wanaagsan. Waxa loogu yeero "waxqabadka xakamaynta xawaaraha" waxaa loola jeedaa in xawaaraha matoorka si macmal ah loo beddelo iyadoo loo eegayo baahiyaha xaaladaha culeyska qaarkood. Matoorka DC wuxuu ogaan karaa xitaa oo siman nidaamka xawaaraha stepless ee culeyska culus, iyo kala duwanaanta nidaaminta xawaaraha waa ballaaran.
(2) Dabayl bilawga weyn. Nidaaminta xawaaraha waxaa loo xaqiijin karaa si isku mid ah iyo dhaqaale ahaan. Sidaa darteed, dhammaan mishiinnada ku bilaabma culays culus ama u baahan hagaajinta xawaaraha isku midka ah, sida birta roga-laabanaysa ee weyn, Winch, locomotive koronto, taraamka, iwm, waxaa wada matoorka DC.
Mabda'a shaqada ee mashiinka DC
Mabda'a shaqada ee mashiinka DC
Mabda'a ah "xoogga ku shaqeynaya korriinka tamarta ee goobta magnetic" ayaa qiyaas ahaan loo adeegsadaa. Labada fiilood ee ugu dambeeya ee gariiradda kicinta ayaa leh isla qulqulka jihada ka soo horjeeda, taas oo ka dhigaysa gariiradda oo dhan inay soo saarto torsionka ku wareegsan shafka oo ka dhigaya gariiradda wareegta.
Si loo sameeyo armature-ku inuu helo qulqulka korantada ee isla jihada, furaha ayaa ku jira sida loo beddelo jihada hadda socota ee gariiradda waqtiga marka dhinaca gariirku uu hoos yimaado tiirarka magnetic of polarity kala duwan, taas oo ah, sidaas- loo yaqaan "commutation". Sidaa darteed, aaladda loo yaqaan commutator waa in lagu daraa. Gawaarida iyo buraashku waxay hubin karaan in hadda ku yaal dhinaca gariiradda ee tiir kasta ka hooseeya ay had iyo jeer isku jiho ahaadaan, si matoorku si joogto ah u wareego. Tani waa mabda'a shaqada ee mashiinka DC.
