Uyayazi indima nezimpawu zebhulashi lekhabhoni lemoto ye-DC?

Ku-DC Motors, amabhulashi e-carbon (abizwa nangokuthi amabhulashi) yizinto eziphambili ezisebenzayo futhi zinemithwalo yemfanelo ebalulekile. Yini izici eziyisisekelo nemisebenzi yeIbhulashi lekhabhoni lemoto ye-DC?

Ubumbano lokuvuselelwa kanye nokugqokwa kokugqoka:Ibhulashi lekhabhoni lemoto ye-DCkuvame ukwenziwa ngama-graphite noma ama-graphite ahlanganisiwe ahlanganiswe ne-wetal powder (njengethusi). I-Graphite inikezela ngokugcotshwa kokhiye kanye nokungqubuzana okuphansi kokuncintisana ukuqinisekisa ukugqoka okulawulayo lapho uhlangana nomqeqeshi ojikelezayo; Ngenkathi izingxenye zensimbi ezingeziwe (ezinjenge-post powder) zithuthukisa kakhulu ukuhambisa ukufeza izidingo zokudluliselwa okukhulu kwamanje. Le nhlanganisela yezinto zokwakha iyenza ikwazi ukubekezelela ukugqoka okujwayelekile kokugqoka ngenkathi kwenziwa kwamanje.

Ukuxhumana okuguquguqukayo okuguquguqukayo Le ndlela yokuxhumana e-Eastic ibalulekile, ngoba iqinisekisa ukuthi noma ngabe umqhutshelwano ungajwayelekile ngenxa yokujikeleza noma ukushaya kancane, ukuxhumeka kukagesi okuqinile, ukunciphisa ukumelana nokuxhumana.

Ukubekwa kwezingxenye zokugqoka: amabhulashi ekhabhoni akuludla ngenxa yokungqubuzana okuqhubekayo komqeqeshi ojikelezayo osheshayo. Impilo yabo yenkonzo ithinteka yizinto ezifana nekhwalithi yezinto ezibonakalayo, isebenza ngesivinini samanje, isivinini semoto, ukuhamba, imvelo (okufana nothuli, umswakama, izinga lokushisa) kanye nengcindezi yentwasahlobo. Idizayini kufanele kube lula ukuyihlola futhi iphinde ihlole.

Ibhuloho lokudluliselwa kwamandla umsebenzi obaluleke kakhulu weIbhulashi lekhabhoni lemoto ye-DC. Emotweni ye-DC, i-armature ejikelezayo (i-rotor) idinga ukuzungeza ukuthola okukhona emthonjeni wamandla we-static wangaphandle ukukhiqiza amandla kazibuthe kanye ne-torque. Njengengxenye emile, ibhulashi lekhabhoni lixhumeke kulayini wamandla ohleliwe ekugcineni okukodwa kanye nama-slides ekutholeni amandla okusebenza kwama-DC ahlelwe ku-rotor shaft (imodi yezimoto), noma ukudlulisa amandla akhiqizwa yi-rotor winding kumthwalo wangaphandle (imodi ye-generator).

Isixhumanisi esibalulekile ekufezekiseni ukulungiswa kwemishini (ukuhamba): ngemoto ye-DC ukujikeleza ngokuqhubekayo, ukuqondiswa kwamanje ku-rotor winding kumele kucishwe ngezikhathi ezithile (okuhanjiswa) okwamanje kudlula umugqa ongathathi hlangothi kwesigxobo se-magnetic. I-Commutator izingxenye zijikeleza nge-rotor, kanye nezingxenye ezihlukile zithinta amabhulashi e-carbon ahleliwe, futhi ngokuzenzakalelayo shintsha umjikelezo ovunguzayo we-rotor uxhumeke ekuhlinzekweni kwamandla (noma umthwalo) ekuxhumaneni namabhulashi. Ibhulashi lekhabhoni libona ngokwangempela ukushintshwa kokushintshwa kwamanje ekujikelezeni komoya ngokuhlelekile nokuhlukaniswa okuhlukahlukene okuhambisana nenqubo ehlukene yeModutator, okungukuthi, iyisisekelo sokusebenza okuqhubekayo kwemoto ye-DC.

Gcina ukuxhumeka kukagesi ezinzile: Hlala uxhumane nomdlalo ngokucindezela kwengcindezi yentwasahlobo, futhi ugcine ukumelana okuphansi, okuphansi kokuxhumeka ngogesi ngisho nakwindlela yokudlidliza noma ye-eccentricity ye-exy, kuqinisekisa ukusebenza kahle kokudluliselwa kwamandla.

Ukususelwa kwezinhlangu zokuhamba Amabhulashi e-carbon aklanywe kahle anekhono elithile lokucisha i-arc (i-graphite ngokwalo lineqhaza elithile), futhi lisize ukudedela le ngxenye yamandla ngendlela enhle yendlela, ukunciphisa ukulimala kwezinhlanzi kumzila nakumoyeni

ukufakwa.

I-Carbon Brush ye-DC motor yibhuloho elibalulekile elihambisanayo phakathi kwesifunda esimisiwe kanye nesifunda esijikelezayo endaweni ye-DC. Ibhekele ukudluliswa okusebenzayo kwamandla kagesi futhi futhi yinto eyenziwa ngumsebenzi womsebenzi oyisisekelo wokushintsha ngokuzenzakalelayo ukuqondiswa kwe-rotor yamanje (ukuhanjiswa). Ukwakheka kwalo okukhethekile (okuphathelene nokungamelana nalokhu okuvinjelwe) kanye nendlela yokuvimba) nendlela yokuqothuka eqinile kuqinisekisa ukusebenza okuzinzile nokuthembekile ezindaweni ezinokhahlo ezishisayo. Kodwa-ke, yikho ngokungenxa yalokhu kungqubuzana okuqhubekayo ukuthi iba yingxenye egqoke ingxenye edinga ukulungiswa njalo nokubuyiselwa esikhundleni, okunomthelela oqondile ekusebenzeni nasekufeni kwemoto. Ukuhlolwa okujwayelekile kanye nokubuyiselwa kwamabhulashi ekhabhoni okugqokwa umkhawulo kuyingxenye ebalulekile yokugcina ukusebenza okujwayelekile kwemoto ye-DC.
