Motor asynchronous: design iyo qalab

waxaa saddex waji motor asynchronous la qafis Dabagaale dib abuurtay 1889, on March 8, caanka ah saynisyahan Ruush iyo injineer Mikhail Osipovich Dolivo-Dobrovolsky. Horeba in sannad ka, December 15, 1890, waxaa lagu soo hindiseen iyo xiranayo motor leh matoorrada warqada-giraanta.

Saddex-waji motor asynchronous - mid ka mid ah qalabka korontada ugu badan in industry ee. Waxaa u fudud in ay ku shaqeeyaan, lagu kalsoonaan karo oo ay leedahay qiimo cadaalad ah u hooseeya. motor asynchronous qaadataa shiidaa sagaashan boqolkiiba tirada guud ee makiinado ay caalamka oo dhan. Waxaa laga heli karaa meel - ka design ka mid ah mashiinka dhaqidda caadiga ah, ilaa dukaamada warshadaha waaweyn, in aan ku xuso xoogga. Wuxuu kaloo sameeyey kacaanka farsamada weyn ee dunida ka mid ah warshadaha.

motor asynchronous - mashiinka a in loogu talagalay in lagu badalo tamarta korontada galay tamarta si farsamaysan. "Asynchronous" micnaheedu "ma synchronous". Waxaa la fahamsan yahay in mashiinka noocan oo kale ah inta jeer ee la taasoo qoqobada beer magnetic ee ay stator ah, had iyo jeer ka weynaan doona heerka ay isku bedbedeli doono qayb ka mid ah la dhaqaajin karo of motor ah - rotor.

motor asynchronous ka kooban yahay qayb ka go'an - stator iyo qayb ka mid ah la dhaqaajin karo qoqobada - rotor ah.

stator waxaa soo ururay oo ka soo go'yaal of steel korontada Tifaftirayaasha iyo sida caadiga ah waxa uu leeyahay qaab cylindrical. The grooves ee muhiimka ah waa la Mire Waqaf oo loogu fuuli jiray stator laga sameeyey oo fuuli jiray silig. windings Stator at yar. dhidibka fuuli jiray Data guud ahaan wareejiyay by xagal 120 digrii eego midba midka kale. The daraf oo windings waxaa laga yaabaa in ku xiran in xiddiga ama Delta (iyada oo ku xidhan danab waxaa laga codsadaa).

rotors waxay leeyihiin mashiinka noocan oo kale ah, sida motor induction ah, oo waa waji-gaaban circuited.

Nooca koowaad (rotor a-circuited gaaban) - core a kaas oo la soo ururay oo copper ama aluminium ulihii dhigay dhexdeeda loogu fuuli jiray ka. dhengedihii ku xiran yihiin siddo dhamaadka, iyo muuqaalka ekaan qafis Dabagaale ah. By habka, si rotor this inta badan nooca loo yaqaan "Dabagaale-qafis". rotor waa ay dhacdo in mar kale laga soo ururiyey shabaqa birta korontada, cadaadisay iyo ku shub aluminium.

rotor Phase waxaa inta badan loo yaqaan giraanta warqada rotor ah. Waxay leedahay saddex waji leh oo loogu fuuli jiray, taas oo run ahaantii waa wax ka duwan windings stator ah. Asal ahaan, darafyadiisa oo ka mid ah windings ee giraanta warqada rotor (wajiga) ku xiran in xiddig. The daraf oo lacag la'aan ah ku xiran yihiin siddo warqada oon ka. circuit The fuuli jiray waxaa badanaa ku daray resistor dheeraad ah ay sabab u tahay jiritaanka burush gaar ah, ku xiran siddooyinkii. resistor noocan oo kale ah u siyaadiyaa iska caabin wareegi rotor ah, kaas oo ku kordhinaya upka iyo hoos u dhac qiimaha macaan inrush hadda - waxaa aad muhiim u ah mashiinada sida, sida saddex waji matoorrada asynchronous.
