I-commutator iyisisetshenziswa sikagesi esisetshenziswa ku-DC motor. Umsebenzi wayo ukushintsha indlela yamanje motor, ngaleyo ndlela ukushintsha isiqondiso ukujikeleza motor. Emotweni ye-DC, isiqondiso samanje sidinga ukushintshwa ngezikhathi ezithile ukuze kugcinwe ukujikeleza kwemoto. Umsebenzi we-commutator ukushintsha njalo isiqondiso samanje lapho i-motor ijikeleza, ukuze injini iqhubeke nokujikeleza ngokuzinzile.
Umgomo oyisisekelo womgibeli ukusebenzisa isethi yokushintsha kwemishini kanye nokuxhumana nogesi ukuze ushintshe indlela yokuhamba kwamanje. Uma i-motor ijikeleza, umshayeli ulawula ukuphuma nokuvala kwamandla ngokuya ngokuma kanye nesiqondiso sokujikeleza kwe-rotor, ngaleyo ndlela eshintsha indlela yamanje. Lolu hlobo lokuthutha oluyimishini luvamise ukusetshenziswa kumamotho amancanyana e-DC, njengezinto zikagesi zasendlini, imishini emincane yemishini, njll.
Emotweni yendabuko ye-DC, umgibeli uvame ukuba nezingxenye ezimbalwa: izikhali, izigxobo, okokuhamba kanye namabhulashi. I-armature iyingxenye ejikelezayo ye-motor, futhi izigxobo kazibuthe ziyingxenye ye-stator ye-motor. I-commutator iqukethe isethi yokushintsha kwemishini kanye nokuxhumana kukagesi lapho kuguqulwa khona isiqondiso se-current. Ibhulashi liyingxenye exhumanisa amandla kagesi kanye nenjini, futhi yethula amanje kukhoyili yenjini ngebhulashi.
Ngokungeziwe kubagibeli abayimishini, amamotho esimanje e-DC nawo asebenzisa kakhulu ubuchwepheshe bokuhamba nge-elekthronikhi. Ubuchwepheshe bokushintshwa kwe-elekthronikhi busebenzisa isilawuli se-elekthronikhi ukuze siguqule indlela yamanje, ngaleyo ndlela ibone ukushintshwa kwenjini. Uma kuqhathaniswa nabagibeli abayimishini, ubuchwepheshe bokuhamba nge-elekthronikhi bunemba nokuthembeka okuphezulu, futhi bungafinyelela ukulawula ukuhamba okunembe kakhudlwana. Ngakho-ke, isetshenziswe kabanzi kwezinye izinhlelo zokusebenza ezidinga ukunemba okuphezulu kokuhamba.
I-commutator idlala indima ebalulekile kuma-DC motors, ithinta ukusebenza kwemoto, ukusebenza kahle nokuthembeka. Umshayeli omuhle angaqinisekisa ukuthi injini isebenza ngokuzinza nangempumelelo, futhi andise impilo yesevisi yemoto. Ngakho-ke, ukuklama, ukwakhiwa kanye nokugcinwa kwe-commutator kubaluleke kakhulu.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukuklama nokukhiqiza ubuchwepheshe babagibeli nakho kuhlala kuthuthuka, futhi ubuchwepheshe obusha be-electronic commutation buyaqhubeka nokuvela, okwenza ukusetshenziswa kwabagibeli kumamotho e-DC kuguquguquke futhi kuthembeke. Ngokuzayo, njengoba ubuchwepheshe bezimoto buthuthuka, abagibeli bazoqhubeka nokuthuthukiswa futhi bathuthukiswe ukuze bahlangabezane nezidingo eziguqukayo zohlelo lokusebenza.
Ngamafuphi, njengengxenye ebalulekile ye-DC motor, i-commutator isetshenziselwa ukushintsha isiqondiso semoto yamanje, ngaleyo ndlela iguqule isiqondiso sokujikeleza kwemoto. Ngobuchwepheshe bokuhamba ngemishini noma nge-elekthronikhi, umgibeli angaqinisekisa ukusebenza okuzinzile kwemoto futhi isetshenziswa kabanzi ezintweni zasendlini, izinto ezisetshenziswa ezimbonini, ezimotweni nakweminye imikhakha. Njengoba ubuchwepheshe buqhubeka buthuthuka, idizayini yabagibeli kanye namasu okukhiqiza athuthuka njalo ukuze ahlangabezane nezidingo eziguqukayo zohlelo lokusebenza.
