Sida laga soo xigtaysoo saaraha motor gariir, mabda'a shaqada eedc motorwaa in la beddelo xoogga koronto-dhaliyaha beddelka ah ee ay dhaliso induction ee gariiradda armature-ka oo loo beddelo xoog koronto oo toos ah oo hadda jira marka laga soo saaro dhammaadka buraashka ee isgaadhsiyaha iyo ficil-celinta buraashka.
Laga soo bilaabo shaqada commutator si loo sharaxo: burushka kuma darto danab dc ah, oo leh dhaqaajiyaha ra'iisul wasaaruhu u jiido armature ka soo horjeeda xawaaraha joogtada ah ee saacadda, labada dhinac ee gariiradda siday u kala horreeyaan waxay gooyaan khadka xoogga bini'aadamka ee hoos yimaada cirifka kala duwan ee birta magnetic, iyo in Kaas oo soo-galintu ay keentay xoogga koronto-dhaliyaha, jihada xoogga korantada sida waafaqsan qaanuunka gacanta midig si loo go'aamiyo.
Mar haddii armatureku si joogto ah u wareego, waxaa lagama maarmaan ah in kirishbooyga hadda sidda lagu xidho cidhifyada gariiradda ab iyo CD ee goob birlab ah si ay beddelkeeda u gooyaan xadhkaha xoogga ee hoos yimaada tiirarka N iyo S, in kasta oo jihada xoogga korantada ee la keenay. gees kasta oo gariiradda iyo gariiradda oo dhan waa is beddelaysaa.
Awoodda koronto-dhaliyaha ee ku jirta gariiradda ayaa ah awood koronto oo beddeleysa, halka xoogga korantada ee dhammaadka burushka A iyo B uu yahay xoogga koronto-dhaliyaha tooska ah ee hadda jira.
Sababtoo ah, habka wareegitaanka qalabka, iyada oo aan loo eegin meesha uu seexanku u leexdo, sababtoo ah dhaqdhaqaaqa dhaqdhaqaaqa iyo buraashka ficil-celinta, xoogga korantada ee uu keeno buraash A iyada oo loo marayo daabka komutatorku had iyo jeer waa xoogga korantada ee cidhifka gariiradda gooynta n - cirifka magnetic field. Sidaa darteed, burushka A wuxuu had iyo jeer leeyahay A polarity wanaagsan.
Si la mid ah, burushka B had iyo jeer wuxuu leeyahay polarity taban, sidaas darteed dhamaadka burushka wuxuu u horseedi karaa garaaca wadnaha wadnaha ee jihada joogtada ah laakiin cabbirka kala duwan awoodda dc ee electromotive waa la heli karaa.
Tani waa sida matoorrada dc u shaqeeyaan. Waxa kale oo ay muujinaysaa in matoorka-dc-du uu dhab ahaantii yahay koronto-dhaliye leh commutator.
Marka loo eego hordhaca soo-saareyaasha matoorada gariirka, laga soo bilaabo xaaladda aasaasiga ah ee elektromagnetic, matoor dc mabda 'ahaan wuxuu u shaqeyn karaa matoor ordaya, sidoo kale waxaa loo ordi karaa koronto-dhaliye, laakiin xaddidaadaha ayaa ka duwan.
Labada burushka ee darafyada dc motor, ku dar danab dc, geli tamarta korantada galay armature, wax soo saarka tamarta makaanikada ee usheeda dhexe, jiid mishiinka wax soo saarka, tamarta korontada galay tamar makaanik oo noqda motor;
Haddii ra'yi-dhaliyaha loo isticmaalo in lagu jiido armature of motor dc, iyo burushku kuma darin danab dc, markaas dhamaadka burushka waxay u horseedi kartaa dc electromotive xoog sida il koronto dc, kaas oo soo saari kara tamarta korontada. Matoorku waxa uu tamarta makaanik u beddelaa tamar koronto oo waxa uu noqdaa matoor dhaliyaha.
Mabda'a ah in isla matoorku uu u shaqeyn karo sida matoor koronto ama koronto-dhaliye. Aragtida mootada waxaa loo yaqaannaa mabda'a dib loo rogi karo.
