Ngokusho kwe-umenzi wemoto yokudlidliza, isimiso sokusebenza se-imoto ye-dcukushintsha amandla e-electromotive ashintshanayo akhiqizwa yi-induction ku-armature coil abe amandla e-electromotive aqondile lapho edonswa ekugcineni kwebhulashi yi-commutator kanye nesenzo se-commutator sebhulashi.
Kusukela emsebenzini we-commutator ukuchaza: ibhulashi alingezi i-dc voltage, nge-prime mover ehudula i-armature counterclockwise constant speed rotation, izinhlangothi ezimbili ze-coil ngokulandelana zisika umugqa wamandla kazibuthe ngaphansi kwe-polarity ehlukene yesigxobo sikamazibuthe, futhi lapho i-induction ikhiqize amandla kagesi, isiqondiso samandla kagesi ngokusho komthetho wesandla sokunene ukuze kunqunywe.
Njengoba i-armature ijikeleza njalo, kuyadingeka ukuthi umqhubi ophethe ugesi abekwe emaphethelweni ekhoyili ab kanye ne-CD ensimini yamagnetic ukuze asike imigqa yamandla ngaphansi kwezigxobo ze-N kanye ne-S ngokushintshana, yize isiqondiso samandla e-electromotive abangelwayo emaphethelweni ekhoyili ngayinye nakuyo yonke ikhoyili siyashintshana.
Amandla e-electromotive abangelwa yi-coil angamandla e-electromotive ashintshanayo, kuyilapho amandla e-electromotive ekugcineni kwebhulashi u-A no-B engamandla e-electromotive aqondile asebenza ku-A.
Ngoba, enkambisweni yokujikeleza kwe-armature, kungakhathaliseki ukuthi i-armature ijika kuphi, ngenxa yesenzo se-commutator kanye ne-brush commutator, amandla e-electromotive abangelwa yi-brush A ngokusebenzisa i-commutator blade ahlala eyi-electromotive force emaphethelweni ekhoyili esika umugqa wensimu yamagnetic ye-n-pole. Ngakho-ke, i-brush A ihlala ine-A polarity enhle.
Ngendlela efanayo, ibhulashi B lihlala line-polarity engemihle, ngakho-ke ukuphela kwebhulashi kungaholela emandleni e-pulse electromotive anesiqondiso esingaguquki kodwa esishintshashintshayo. Uma inani lama-coil ngaphansi kwensika ngayinye landa, izinga lokudlidliza kwe-pulse lingancishiswa futhi amandla e-dc electromotive angatholakala.
Lena indlela ama-dc motor asebenza ngayo. Kubonisa nokuthi i-sub-dc motor empeleni iyi-ac generator ene-commutator.
Ngokusho kokwethulwa kwabakhiqizi bezimoto ezidlidlizayo, kusukela esimweni esiyisisekelo se-electromagnetic, i-dc motor empeleni ingasebenza njengemoto esebenza, futhi ingasebenza njengejeneretha, kodwa imikhawulo ihlukile.
Emaphethelweni amabili ebhulashi lemoto ye-dc, engeza i-voltage ye-dc, faka amandla kagesi ku-armature, amandla omshini avela ku-shaft yemoto, donsa imishini yokukhiqiza, amandla kagesi abe amandla omshini bese uba yimoto;
Uma i-prime mover isetshenziswa ukudonsa i-armature ye-dc motor, futhi ibhulashi lingangezi i-dc voltage, khona-ke ukuphela kwebhulashi kungaholela ku-dc electromotive force njengomthombo wamandla we-dc, ongakhipha amandla kagesi. I-motor iguqula amandla omshini abe amandla kagesi bese iba yi-generator motor.
Isimiso sokuthi injini efanayo ingasebenza njengenjini kagesi noma njengejeneretha. Embonweni wezimoto ibizwa ngokuthi isimiso esiguquguqukayo.
