I-DC ecociweyoImoto luhlobo oluqhelekileyo lwemoto olusebenzisa amandla angoku ngqo (DC). Zisetyenziswa kwiindlela ezahlukeneyo zokusebenza, ukusuka kwii-elektroniki ezincinci zabathengi ukuya koomatshini abakhulu bemizi-mveliso. Kweli nqaku lifutshane lentshayelelo, siza kujonga ngokusondeleyo indlela ezisebenza ngayo iimoto ze-DC ezibrashiweyo, izinto zazo, kunye nokusetyenziswa kwazo.
Umsebenzi osisiseko weImoto ye-haptic enobubanzi obuyi-8mmibandakanya ukusebenzisana kwentsimi yemagnethi kunye nomsinga wombane ukuvelisa intshukumo. Izinto eziphambili zemoto ye-DC ebhrashiweyo ziquka i-stator, i-rotor, i-commutator kunye neebhrashi. I-stator yinxalenye esisigxina yemoto kwaye iqulethe iimagnethi okanye ii-electromagnetic coils ngaphakathi kwayo, ngelixa i-rotor yinxalenye ejikelezayo yemoto kwaye iqulethe i-armature. I-commutator sisitshixo esijikelezayo esilawula ukuhamba komsinga ukuya kwi-armature, kwaye iibhrashi ziqhagamshelana ne-commutator ukuze zidlulisele amandla kwi-armature.
Xa umbane usetyenziswa kwi-motor, kwenziwa i-magnetic field kwi-stator. Le magnetic field isebenzisana ne-magnetic field ye-rotor, nto leyo ebangela ukuba i-rotor ijikeleze. Xa i-rotor ijikeleza, i-commutator kunye neebhrashi zisebenza kunye ukutshintsha ngokuqhubekayo indlela yombane ohamba ngayo kwi-armature ukuqinisekisa ukuba i-rotor iyaqhubeka nokujikeleza kwicala elifanayo.
Umgaqo Wokusebenza
Ukusebenza kwemoto ye-DC exutyiweyo kusekelwe kumgaqo osisiseko wokungeniswa kwe-electromagnetic kunye nokusebenzisana phakathi kwamacandelo emagnethi. Xa umbane unikezelwa kwimoto, i-stator—nokuba ixhotyiswe ngeemagnethi ezisisigxina okanye ii-electromagnetic coils—ivelisa intsimi yemagnethi ezinzileyo. Kwangaxeshanye, umbane uhamba ngee-armature windings kwi-rotor, uguqula i-rotor ibe yi-electromagnet. Intsimi yemagnethi ye-stator kunye nentsimi yemagnethi ye-rotor ziyasebenzisana, zivelisa i-torque ejikelezayo (i-Lorentz force) ebangela ukuba i-rotor ijikeleze.
Inkalo ebalulekileyo yokugcina ukujikeleza okuqhubekayo kwicala elinye kukusebenzisana phakathi kwe-commutator kunye neebhrashi. Njengoko i-rotor ijika, i-commutator—inxalenye ye-split-ring eqhotyoshelwe kwi-rotor shaft—ijikeleza ngaxeshanye. Iibhrashi, ezenziwe ngekhabhoni okanye i-graphite, zihlala zinxibelelana rhoqo neenxalenye ze-commutator. Njengoko i-rotor ifikelela kwiindawo ezithile, i-commutator itshintsha indlela yomsinga ohamba ngayo kwii-armature windings. Oku kuguqulwa kwexesha lomsinga kuqinisekisa ukuba i-magnetic polarity ye-rotor xa ithelekiswa ne-stator ihlala ihambelana, ivelisa amandla okujikeleza aqhubekayo kwaye ithintela i-rotor ukuba ingami okanye ibuyele umva.
Iimpawu zokusebenza
Ukusebenza kakuhle
Ukusebenza kakuhle kweemoto zeDC ezibrashiweyo kuyahluka ngokuxhomekeke kuyilo lwazo, ubungakanani, kunye neemeko zokusebenza. Iimoto zeDC ezincinci ezibrashiweyo, ezifana nezo zisetyenziswa kwizixhobo ze-elektroniki zabathengi, zihlala zinoluhlu lokusebenza oluyi-50-70%, ngelixa iimoto ezinkulu zezinga lemizi-mveliso zinokufikelela kwi-85% nangaphezulu. Izinto eziphambili ezichaphazela ukusebenza kakuhle ziquka ukungqubana kwe-brush-commutator, ukulahleka kobhedu kwii-armature windings, ukulahleka kwentsimbi kwi-stator kunye ne-rotor cores, kunye nokulahleka koomatshini (umz., ukungqubana kweebheringi). Ukuguguleka kwebrashi kunye nokonakala kwe-commutator ngokuhamba kwexesha nako kunokukhokelela ekunciphiseni ukusebenza kakuhle.
