Motor Synchronous - faa'iidada iyo khasaaraha

Waxaa ugu ballaaran loo isticmaalo mashiinka sida a sida motor a synchronous la helay in industry ah halkaas oo ay jiraan orodka korontada xawaare joogto ah. Tusaale ahaan, komberesarrada la matoorada awood badan, shubmo actuators. Sidoo kale, motor ka synchronous waa qayb muhiim ah, iyo qalabka badan qoyska, sida ay tahay in saacadood.

Mabda'a hawlgalka mashiinka tani waa mid fudud ilaa xad. The dhexgalka duurka qoqobada magnetic of armature ka soo saaray talantaalli hadda beeraha iyo magnetic on ulaha inductor ah ee hadda joogta waxaa aasaas u ah mabda'a hawlgalka qalab noocan oo kale ah sida baabuurta korontada synchronous. Sida caadiga ah, inductor ah ku yaal rotor ah, oo ay noqoto meesha - stator ah. matoorada awood badan sida ulaha isticmaalaya electromagnets. Laakiin waxaa jira nooc ka mid ah low-awoodda - motor a synchronous la magnet-joogta ah. Farqiga ugu muhiimsan ee u dhexeeya mashiinada synchronous iyo asynchronous - stator iyo design rotor.

Si aad u dardar motor ilaa heerka xawaaraha lagu qiimeeyo inta badan isticmaalaan hab asynchronous. In hab this, inductor ku fuuli jiray gaaban-circuited. Ka dib markii engine la geeyo xawaaraha lagu qiimeeyo, rectifier siiya DC inductor. Kaliya xawaaraha magacaaban motor synchronous madax bannaan u shaqayn karto.

motor a noocan oo kale ah waxay leedahay faa'iidooyin badan. Isagu waa amar of magnitude sii adag mashiinka asynchronous, laakiin tani waa mowjadda by tiro ka mid ah faa'iidooyinka. Mid ka mid ah faa'iidooyinka ugu weyn ee - in ay awood u shaqeeyaan iyada oo aan isticmaalka awoodda Waxyeelo ama saameyn. Sayidka factor awood engine waa loo siman yahay si ay midnimo. Under xaaladahan, a motor AC synchronous si gaar ah waa qayb network load firfircoon. saamaynta dhinaca A waa in la yareeyo size motor, (waayo, motor induction ah, stator ku fuuli jiray waxaa loo xisaabiyaa iyo hadda firfircoon oo Waxyeelo on). Si kastaba ha ahaatee, motor ka synchronous abuuri karaan awood dhab ah oo Waxyeelo, ka hawlgala hab overexcitation.

motor ayaa synchronous waa wax badan ka yar xasaasi u ah isbedbedelka iyo danab lagu dhibciyo in shabakadda. Sida baabuur koronto ku leeyihiin iska caabin ah oo ka sareeya si ay overloads. suurto gal ah in la kordhiyo awoodda dollar ee engine ah by sii kordhaya hadda excitation ah. Faa'iidada leh mishiinka synchronous sidoo kale waa joogto ah xawaaraha wareeg magacaaban kasta load (dollar marka laga reebo).

Waxaa sugan, mashiinka noocan oo kale ah sida baabuurta a synchronous ayaa ku liitaan gaar ah ay. Waxay la xidhiidha kharashka sare oo howl adag. Dhibaatada ugu weynna waa excitation oo ka mid ah baabuurta iyo sal-galay synchronism. Currently helay exciters thyristor faafinta, kaas oo ay leeyihiin a badan -oolnimada, badan, waayo, wareer korontada. Si kastaba ha ahaatee, ay kharashka waa inta ka sareeya. Isticmaalka biiro thyristor ku xallin karo dhibaatooyin badan: excitation xeerka hadda ku fiicnayn, taageero cosine PHI qiimaha joogto ah, danab gacanta ku banjarin ka, xakameeyo hadda stator iyo rotor ee hab degdegga ah, iyo haddii ay dhacdo of dollar.
