Ngokutsho kweumenzi wemoto yokungcangcazela, umgaqo wokusebenza weimoto ye-dckukutshintsha amandla e-electromotive alternating aveliswa yi-induction kwi-armature coil ibe ngamandla e-electromotive current current xa etsalwa kwisiphelo sebrashi yi-commutator kunye nesenzo se-commutator sebrashi.
Ukusuka kumsebenzi we-commutator ukuchaza: ibhrashi ayongezi i-dc voltage, kunye nomhambisi oyintloko otsala i-armature counterclockwise constant speed rotation, amacala amabini e-coil anqumla umgca wamandla emagnethi phantsi kwe-polarity eyahlukileyo ye-magnetic pole, kwaye apho i-induction ivelise amandla e-electromotive, ulwalathiso lwamandla e-electromotive ngokwemigaqo yesandla sasekunene ukuze imisele.
Ekubeni i-armature ijikeleza rhoqo, kuyimfuneko ukuba umqhubi othwala umsinga afakwe kwimiphetho ye-coil ab kunye ne-CD kwintsimi yemagnethi ukuze asike imigca yamandla phantsi kweepali ze-N kunye ne-S ngokutshintshana, nangona ulwalathiso lwamandla e-electromotive abangelwayo kumphetho ngamnye we-coil nakuyo yonke i-coil lutshintshana.
Amandla e-electromotive abangelwayo kwi-coil ngamandla e-electromotive atshintshanayo, ngelixa amandla e-electromotive ekupheleni kwebrashi u-A no-B ngamandla e-electromotive angoku ngqo.
Kuba, kwinkqubo yokujikeleza kwe-armature, nokuba i-armature ijika phi, ngenxa yesenzo se-commutator kunye ne-brush commutator, amandla e-electromotive abangelwa yi-brush A nge-commutator blade ahlala e-electromotive force emphethweni we-coil esika umgca we-magnetic field we-n-pole. Ke ngoko, i-brush A ihlala ine-A polarity entle.
Ngendlela efanayo, ibrashi B isoloko ine-polarity engalunganga, ngoko ke isiphelo sebrashi sinokukhokelela kwi-pulse electromotive force yecala elingaguqukiyo kodwa ubukhulu obuhlukeneyo. Ukuba inani lee-coils phantsi kwepali nganye linyusiwe, inqanaba lokungcangcazela kwe-pulse lingancitshiswa kwaye amandla e-dc electromotive angafunyanwa.
Le yindlela ezisebenza ngayo iimoto ze-dc. Ikwabonisa ukuba i-sub-dc motor ngokwenene yi-ac generator ene-commutator.
Ngokwentshayelelo yabavelisi beemoto zokungcangcazela, kwimeko ye-electromagnetic esisiseko, i-dc motor ngokomgaqo ingasebenza njengemoto esebenzayo, ikwanokuqhutywa njengejenereyitha, kodwa imida yahlukile.
Kwiziphelo ezimbini zebhrashi yemoto ye-dc, yongeza i-dc voltage, faka amandla ombane kwi-armature, amandla oomatshini avela kwi-shaft yemoto, rhuqa oomatshini bokuvelisa, amandla ombane abe ngamandla oomatshini kwaye ube yimoto;
Ukuba i-prime mover isetyenziselwa ukutsala i-armature ye-dc motor, kwaye ibrashi ayongezi i-dc voltage, isiphelo sebrashi sinokukhokelela kwi-dc electromotive force njengomthombo wamandla e-dc, onokukhupha amandla ombane. I-motor iguqula amandla oomatshini abe ngamandla ombane kwaye ibe yi-generator motor.
Umgaqo wokuba imoto efanayo inokusebenza njengemoto yombane okanye njengejenereyitha. Kwithiyori yemoto ibizwa ngokuba ngumgaqo oguqukayo.
