Shaft current waa dilaaga weyn ee matoorada soo noqnoqda ee isbedbedelaya, matoorada waaweyn, matoorrada danabka sareeyo iyo koronto-dhaliyeyaasha, aad bayna u dhib badan u leedahay nidaamka xadhkaha mootada.Waxaa jira kiisas badan oo ku guul darreystay nidaamka xajinta sababtoo ah taxadar la'aanta hadda jirta.

Dabeecadda hadda jirta waxaa lagu gartaa koronto yar iyo hadda oo sareysa, dhaawaca nidaamka xajinta ayaa la dhihi karaa waa mid aan laga fursan karin.Jiilka hadda jira ee shaft waxaa sabab u ah danab shaft iyo loop xiran.Si loo xalliyo dhibaatada hadda jirta, waxaa lagu xallin karaa iyadoo la baabi'inayo korantada shafka ama jarista wareegga.

Wareega birlabeedka aan dheeli tirnayn, sahayda korantada rogayaasha, koronto-soo-saarka korantada, dallacaadda korantada iyo faragelinta sahayda korantada dibadda ayaa laga yaabaa inay dhammaan dhaliyaan danab shaft ah.Wajahaya wareeg xiran, usheeda weyn ee hadda socota waxay sababi doontaa in xajintu ay baabi'iso kulaylka wakhti aad u yar gudaheed.Xirmooyinka gubanaya usheeda dhexe waxay kaga tagi doonaan calaamado u eg sabuuradda dhaqidda oogada sare ee giraanta gudaha

Si looga fogaado dhibaatada hadda jirta, tallaabooyinka lagama maarmaanka ah waa in lagu qaadaa qaabeynta iyo habka wax soo saarka ee matoorka, sida ku darista tallaabooyinka dahaarka ee lagama maarmaanka ah daboolka dhammaadka iyo gacan-qaadashada.Xidhiidhku wuxuu kordhiyaa burushka kaarboonka ee daadsan.Marka laga eego aragtida isticmaalka, waa hal mar-iyo-dhan-dhammaan cabbir si loo qaado tallaabooyinka wareegga wareegga ee qaybaha, halka isticmaalka hababka leexinta ay keeni karto beddelka qalabka burushka kaarboonka, ugu yaraan inta lagu jiro wareegga dayactirka ee mishiinka, nidaamka burushka kaarboonka waa in aanu dhibaato la kulmin.

Baaxadda iyo awoodda xajinta ee dahaarka dahaarka ah iyo sida caadiga ah waa isku mid.Farqiga u dhexeeya ayaa ah in dahaarka dahaarka ah uu si fiican uga hortagi karo marinka hadda socda, iyo xirashada dahaaran ayaa ka fogaan karta waxyeelada ay keento daxalka korantada.Hawlgalku waa mid la isku halleyn karo, oo daboolka daboolan wuxuu ka fogaan karaa saameynta daxalka korantada ee hadda la kiciyay ee xajinta, wuxuuna ka ilaalinayaa hadda inuu waxyeello u geysto dufanka, walxaha rogrogaya iyo jidadka orodka.

Marka matoorka lagu shaqeeyo sahayda korontadu, korantada sahayda korantada waxay ka kooban tahay qaybo iswaafajin ah oo heer sare ah, taas oo sababta induction elektromagnetic inta u dhaxaysa darafyada gariiradaha dabaylaha ee stator, qaybaha fiilooyinka, iyo shafka wareega, taas oo dhalinaysa danab shaft ah.

Dabaylaha stator ee matoor asynchronous waxa gundhig in booska stator core, oo waxaa jira capacitances qaybsan inta u dhaxaysa leexashada stator dabaylaha iyo inta u dhaxaysa dabaylaha stator iyo jir motor.Korantada qaabka caadiga ah si aad ah ayey isu beddeshaa, iyo qulqulka qulqulka ayaa laga sameeyay daasadaha mootada ilaa terminalka dhulka iyada oo loo marayo awoodda qaybsan ee dabaysha matoorka.Daaqaddan hadda socota waxay sameyn kartaa laba nooc oo faragelin koronto ah, shucaac iyo kicin.Sababtoo ah isku dheelitir la'aanta wareegga magnetic ee matoorka, soo-gelinta korantada iyo korantada qaabka caadiga ah ayaa ah sababaha tamarta shafka iyo hadda.
