Ihe na mkpa nke ahịhịa carbon

 

Igwe ọkụ carbonma ọ bụ brushes eletrik bụ ọtụtụ ebe na-eji eletriki akụrụngwa. A na-eji ha ebufe akara ma ọ bụ ike n'etiti ofu akụkụ na-atụgharị akụkụ nke ụfọdụ Motors ma ọ bụ ndị na-emepụta ihe. The udi bụ akụkụ anọ, na metal wires arụnyere na mmiri. brushes carbon bụ ụdị kọntaktị na-amị amị, yabụ ọ dị mfe iyi na kwesịrị ka edochie ya mgbe niile yana nkwụnye carbon nke na-apụ apụ a ga-ehicha ya.

 

Isi ihe dị na brush carbon bụ carbon. Mgbe ị na-arụ ọrụ, a na-agbanye ya na mmiri iji rụọ ọrụ na akụkụ na-atụgharị dị ka ahịhịa, ya mere a na-akpọ ya brush carbon. Isi ihe bụ graphite.

 

Graphite bụ ihe okike, isi ya akụrụngwa bụ carbon, agba bụ nwa, opaque, ọkara ọla luster, ala ike, enwere ike iji mbọ aka were were, graphite na diamond bụ ma carbon, ma ihe onwunwe ha dị nnọọ iche , nke bụ n'ihi na dị iche iche nhazi nke carbon atom. Ọ bụ ezie na ihe mejupụtara graphite bụ carbon, ọ bụ ihe na-eguzogide okpomọkụ dị elu nke nwere ebe mgbaze nke 3652 ° C. Iji Nke a dị elu okpomọkụ na-eguzogide ihe onwunwe, graphite nwere ike hazie n'ime a elu okpomọkụ na-eguzogide ọgwụ kemịkalụ.

 

Igwe ọkụ eletrik nke graphite bụ dị nnọọ mma, karịrị ọtụtụ ọla na ọtụtụ narị ugboro nke ndị na-abụghị ọla, ya mere a na-emepụta ya n'ime akụkụ ndị na-eduzi dị ka electrodes na brushes carbon; esịtidem Ọdịdị nke graphite na-ekpebi ya mma mmanu, na anyị na-emekarị jiri ya n'ọnụ ụzọ ime nchara Ịtinye uzuzu pensụl ma ọ bụ graphite n'ime mkpọchi ga-eme ọ dị mfe imeghe ụzọ. Nke a kwesịrị ịbụ mmetụta mmanye nke graphite.

 

Igwe ọkụ carbona na-ejikarị na DC ngwa eletriki. Ihe mejupụtara moto ndị a na-ehicha ahịhịa bụ stator na rotor. N'ime moto DC, iji mee ka rotor na-atụgharị, ntụziaka nke ugbu a kwesịrị ka agbanwe agbanwe mgbe niile, ma ọ bụghị na rotor nwere ike ịtụgharị naanị ọkara a okirikiri. brushes carbon na-arụ ọrụ dị oke mkpa na moto DC. Igwe ọkụ carbon na-eduzi ugbu a n'etiti akụkụ ndị na-akpụ akpụ nke moto. Nhazi a bụ ihe na-amị amị Nduzi nke nwere ike ịnyefe ugbu a site na njedebe a kapịrị ọnụ na akụkụ na-atụgharị nke generator ma ọ bụ moto. Igwe ikuku carbon nwere ọtụtụ brushes carbon, ya mere usoro nduzi a na-emekwa ka brushes carbon dị mfe iyi, na brushes carbon na-agbanwekwa ntụziaka nke ugbu a, ya bụ, ọrụ nke ntughari.

 

The brushed moto nakweere n'ibu commutation, ogwe ndọta dị n'èzí anaghị emegharị ma eriri nke ime na-agagharị. Mgbe moto na-arụ ọrụ, commutator na eriri igwe na-atụgharị ọnụ, na carbon brush na magnetik ígwè adịghị akpali, otú commutator na ndị brush carbon na-emepụta esemokwu iji mechaa ngbanwe nke ugbu a uzo.

 

Ka moto na-agbagharị, mkpuchi dị iche iche ma ọ bụ abụọ dị iche iche nkebi nke otu eriri igwe na-ume, nke mere na abụọ okporo osisi nke oghere ndọta nke eriri igwe na-emepụta nwere akụkụ nwere okporo osisi abụọ dị nso na-adịgide adịgide magnet stator, na ike na-eme site na ichupu nke otu osisi na mma nke emegide osisi na-akwọ ụgbọala na moto iji bugharia.

 

Igwe ọkụ carbona na-ejikwa AC akụrụngwa. Ọdịdị na ihe nke AC moto carbon brushes na DC moto brushes carbon bụ otu. Na moto AC, a na-eji brushes carbon mgbe ụfọdụ winding rotors chọrọ mgbanwe ọsọ, dị ka ọkụ eletrik anyị na-ejikarị na igwe na-egbuke egbuke, na ha kwesịrị iji dochie brushes carbon ugboro ugboro.
