Yintoni umhambisi?

I-commutator sisixhobo sombane esisetyenziswa kwi-DC motor. Umsebenzi wayo kukutshintsha indlela yangoku kwimoto, ngaloo ndlela itshintsha indlela yokujikeleza kwemoto. Kwimoto ye-DC, isalathiso sangoku kufuneka sitshintshwe ngamaxesha athile ukuze kugcinwe indlela yokujikeleza kwemoto. Umsebenzi we-commutator kukutshintsha rhoqo ulwalathiso lwangoku xa i-motor ijikeleza, ukwenzela ukuba i-motor ikwazi ukuqhubeka nokujikeleza ngokuzinzileyo.

Umgaqo osisiseko we-commutator kukusebenzisa isethi yokutshintsha komatshini kunye noqhagamshelwano lombane ukutshintsha indlela yokuhamba kwangoku. Xa i-motor ijikeleza, i-commutator ilawula i-on and off yangoku ngokuhambelana nendawo kunye nolwalathiso lokujikeleza kwe-rotor, ngaloo ndlela itshintsha isalathiso sangoku. Olu hlobo lokuhambisa oomatshini ludla ngokusetyenziswa kumandla amancinci eenjini zeDC, ezifana nezixhobo zasekhaya, izixhobo ezincinci zoomatshini, njl.

Kwimoto yemveli ye-DC, umhambisi uhlala equlathe iinxalenye ezininzi: izixhobo, iipali, isihambisi kunye neebhrashi. I-armature yinxalenye ejikelezayo yemoto, kwaye izibonda zemagneti ziyinxalenye yestator yemoto. I-commutator iquka isethi yokutshintsha komatshini kunye noqhagamshelwano lombane apho ulwalathiso lwangoku lutshintshwa. Ibrashi yinxalenye edibanisa unikezelo lwamandla kunye nemoto, kwaye yazisa okwangoku kwikhoyili yemoto ngebrashi.

Ukongeza kwii-commutators zoomatshini, iinjini zale mihla ze-DC zisebenzisa kakhulu itekhnoloji yothungelwano lwe-elektroniki. Itekhnoloji yothungelwano lwe-elektroniki isebenzisa isilawuli se-elektroniki ukuguqula indlela yangoku, ngaloo ndlela iqonda ukutshintshwa kwemoto. Xa kuthelekiswa nabahambisi boomatshini, itekhnoloji yothungelwano lwe-elektroniki inokuchaneka okuphezulu kunye nokuthembeka, kwaye inokufikelela kulawulo oluchanekileyo ngakumbi. Ke ngoko, isetyenziswe ngokubanzi kwezinye izicelo ezifuna ukuchaneka okuphezulu kokutshintsha.

I-commutator idlala indima ebalulekileyo kwiinjini ze-DC, ezichaphazela ukusebenza kwemoto, ukusebenza kakuhle kunye nokuthembeka. Umhambisi olungileyo unokuqinisekisa ukuba imoto isebenza ngokuzinzileyo nangokufanelekileyo, kwaye yandisa ubomi benkonzo yemoto. Ngoko ke, ukuyila, ukwenziwa kunye nokugcinwa kwe-commutator kubaluleke kakhulu.

Ngenkqubela phambili eqhubekayo yetekhnoloji, uyilo kunye neteknoloji yokuvelisa abakhweli nazo zihlala ziphucuka, kunye nobuchwepheshe obutsha bothungelwano lwe-elektroniki buyaqhubeka nokuvela, okwenza ukusetyenziswa kwabahambi kwiinjini ze-DC kube bhetyebhetye kwaye kunokuthenjwa. Kwixesha elizayo, njengoko itekhnoloji yemoto ikhula, abakhweli baya kuqhubeka bephuculwa kwaye balungiselelwe ukuhlangabezana neemfuno eziguqukayo zesicelo.
