Ngokutsho kwevibration umenzi wemoto, umgaqo wokusebenza wedc motorkukutshintsha i-alternating electromotive force eyenziwa ngokungeniswa kwi-coil ye-armature ibe yi-electromotive force yangoku xa itsalwa ukusuka ekupheleni kwebrashi ngumqhubi kunye nesenzo somqhubi we-brush.
Ukusuka kumsebenzi we-commutator ukucacisa: ibrashi ayongezi i-dc voltage, kunye ne-prime mover irhuqa i-armature counterclockwise ukujikeleza kwesantya esingaguqukiyo, amacala amabini ekhoyili ngokulandelelana asike umgca wamandla kazibuthe phantsi kwe-polarity eyahlukileyo yesibonda samagnetic, kwaye ngaphakathi. apho i-induction yavelisa amandla e-electromotive, i-electromotive force direction ngokomthetho wesandla sokunene ukumisela.
Ekubeni i-armature ijikeleza ngokuqhubekayo, kuyimfuneko ukuba umqhubi ophetheyo wangoku ukuba athotyelwe kwi-coil edges ab kunye ne-CD kwindawo yamagnetic ukunqumla imigca yamandla phantsi kwe-N kunye ne-S poles, nangona isalathiso samandla e-electromotive induced. kumphetho ngamnye wekhoyili kwaye kuyo yonke ikhoyili iyatshintshana.
I-electromotive force eyenziwe kwi-coil yi-electromotive force etshintshanayo, ngelixa i-electromotive force ekupheleni kwebrashi A kunye ne-B yi-electromotive force yangoku.
Ngenxa yokuba, kwinkqubo yokujikeleza kwe-armature, kungakhathaliseki ukuba i-armature ijika phi, ngenxa yesenzo se-commutator kunye ne-brush commutator, i-electromotive force eyenziwa yi-brush A ngokusebenzisa i-blade ye-commutator isoloko inamandla e-electromotive ekupheleni kwekhoyili yokusika i-n. -umgca we-pole magnetic field.Ngoko ke, ibrashi A isoloko ine-A positive polarity.
Ngendlela efanayo, i-brush B isoloko ine-polarity engalunganga, ngoko ke isiphelo sebrashi sinokukhokelela kwi-pulse electromotive force yolwalathiso oluqhubekayo kodwa ubukhulu obuhlukayo. amandla e-electromotive e-dc angafumaneka.
Le yindlela iimotor ze-dc ezisebenza ngayo.Kwabonisa ukuba i-sub-dc motor eneneni yi-ac generator ene-commutator.
Ngokokwaziswa kwabavelisi beemoto zokungcangcazela, ukusuka kwimeko yesiseko se-electromagnetic, i-dc motor ngokomgaqo inokusebenza njengemoto ebalekayo, nayo inokuqhutywa njengejenereyitha, kodwa imiqobo yahlukile.
Kwiziphelo ezimbini zebrashi yemoto ye-dc, yongeza i-dc yombane, igalelo lamandla ombane kwi-armature, amandla ombane aphuma kwi-motor shaft, oomatshini bokutsala, amandla ombane kumandla oomatshini kwaye abe yimoto;
Ukuba i-prime mover isetyenziselwa ukutsala i-armature ye-dc motor, kwaye ibrashi ayifaki i-dc voltage, emva koko isiphelo sebrashi sinokukhokelela kumandla ombane we-dc njengomthombo wamandla we-dc, onokukhupha amandla ombane.Imoto iguqula amandla oomatshini abe ngamandla ombane kwaye ibe yinjini yokuvelisa.
Umgaqo wokuba injini enye inokusebenza njengenjini yombane okanye njengejenereyitha. Kwithiyori yemoto ibizwa ngokuba ngumgaqo obuyiselwa umva.
