Guud ahaan, qalabyada kala duwani waxay leeyihiin noocyo kala duwan oo matoor ah iyo goobo kala duwan oo la isticmaalo, sidaas darteed waxaa jira noocyo badan iyo xawaarahooda matoorada. Soo saarista sibidhka, alaabta silicate, qalabka dhismaha cusub, alaabta dib u soo celinta, bacriminta, ka faa'iidaysiga birta madow iyo kuwa aan birta ahayn, dhalooyinka iyo ceramics, miraha kubada ayaa inta badan la isticmaalaa. Haddaba matoor noocee ah ayaa loo dooran karaa mashiinnada kubbadda? Inta badan waxaa jira taxane soo socda.
Ka hore waamatoor asynchronous ahs. Marka laga reebo mashiinnada kubbadda yaryar ee u adeegsada matoorada qafiska Dabagaallada ee wadista, inta badan mishiinnada kubbadda yaryar iyo kuwa dhexdhexaadka ah waxay u isticmaalaan wadista matoorrada aan kala sooc lahayn ee saddex-waji ah. Khasaaraha ugu weyn ee matoorrada asynchronous ee wadista kubbadda waa in ay fudud yihiin oo raqiis yihiin, leeyihiin torque bilawga ah oo ku filan, si toos ah u bilaabi kara mashiinka kubbadda, oo lagu xakameynayo isku xirka caabbinta taxanaha ah ee rotor-ka. Midda labaad waa matoorrada isku midka ah. Waxaa jira laba nooc oo matoorrada lagu kaxeeyo shiidlada kubbadda, kuwaas oo kala ah matoorrada isku-dhafka ah ee bilowga hooseeya iyo kuwa waaweyn. matoorrada isku midka ah ee xawaaraha hooseeya ee xawaaraha sareloogu talagalay miraha kubbadda. Kan ugu dambeeya waa kaninduction matoor synchronous. Waxay leedahay faa'iidooyinka soo socda: waxa uu leeyahay faa'iidooyinka torque bilowga weyn laakiin hadda bilowga yar yar marka la bilaabayo, oo uu leeyahay faa'iido factor awood horumarsan ka badan motor synchronous marka la shaqeeyo, sidaas xalinta dhibaatada magdhow inertial of koronto warshad sibidhka. Khasaaraha ayaa ah in wax-soo-saarku uu adag yahay qiimuhuna uu qaali yahay, laakiin matoorka isku-dhafka ah ee induction wuxuu leeyahay mustaqbal rajo leh sida matoorka gudbinta ee mashiinka wax-shiidka ee waaweyn.
Markaad dooranayso mashiinka kubbadda kubbadda, marka lagu daro tixgelinta sifooyinka kor ku xusan, maalgelinta bilowga ah iyo kharashyada hawlgalka waa in la tixgeliyaa. Tixgeli nooca mootada ee qalabka kale ee warshadda sibidhka, taas oo ah, qodobka tamarta ee shabakadda korontada ee warshadda oo dhan. Marka la go'aaminayo korantada la qiimeeyay, xaaladda isbeddelka ee korantada korantada ee aagga ay ku taal warshadda sibidhka iyo cabbirka awoodda korantada korontada waa in la tixgeliyaa. Matoorka waa in lagu gartaa iyadoo la raacayo qorshaha gudbinta farsamada ee kubbadda kubbadda, iyo xaaladaha wax soo saarka farsamada ee habka hoos u dhigista waa in la tixgeliyaa marka la qiimeynayo.
