1. Isi ihe dị iche: moto brush na-anakwere nrụgharị igwe, ogwe ndọta anaghị emegharị, mmanụ ọkụ na-atụgharị. Mgbe moto na-arụ ọrụ, cfuel na commutator na-atụgharị, magnet na brush carbon anaghị atụgharị, na mgbanwe mgbanwe nke cfuel ugbu a na-emezu site na commutator na brush na-agbagharị na moto. Moto na-enweghị brush na-anabata ntugharị eletrọnịkị, mmanụ ọkụ anaghị agagharị na ogwe ndọta na-atụgharị.
2. Ọdịiche nke usoro nhazi ọsọ ọsọ: N'ezie, a na-achịkwa moto abụọ ahụ site na ụkpụrụ voltaji, naanị n'ihi na DC na-enweghị brush na-eji igwe eletriki eme ihe, a chọrọ njikwa dijitalụ. A na-eji ahịhịa carbon na-ebugharị brushless DC, yana sekit analọgụ ọdịnala dị ka silicon na-achịkwa, nwere ike ịchịkwa ya, nke dị mfe.
Ọdịiche dị na arụmọrụ:
▶ 1. Moto ahịhịa nwere usoro dị mfe, ogologo oge mmepe yana teknụzụ tozuru oke.
N'oge ọmụmụ moto na narị afọ nke iri na itoolu, moto bara uru emepụtara bụ enweghị brush, ya bụ AC squirrel-cage asynchronous moto, nke ejirila ọtụtụ ebe kemgbe ọgbọ AC. Agbanyeghị, enwere ọtụtụ ntụpọ a na-apụghị imeri emeri na moto asynchronous, nke mere na mmepe nke teknụzụ moto na-eji nwayọ.
▶ 2. DC brush moto nwere ngwa ngwa nzaghachi ọsọ na nnukwu mmalite torque:
DC brush moto nwere nzaghachi mmalite ngwa ngwa, nnukwu mmalite torque, mgbanwe ọsọ dị nro, na ọ naghị enwe mmetụta ịma jijiji site na efu ruo oke ọsọ. Ọ nwere ike ibu ibu ibu mgbe ịmalite. Moto na-enweghị brush nwere nnukwu nguzogide mmalite (inductance), ya mere ọ nwere obere ihe ike, dịtụ ntakịrị mmalite torque, humming mgbe ịmalite, na-esonyere ya na vibration siri ike, obere ịkwọ ụgbọala mgbe ịmalite.
▶ 3. DC brush moto na-agba ọsọ were were na-enwe ezigbo mmalite na braking mmetụta:
A na-eji voltaji na-ahazi moto ahịhịa, yabụ bido na breeki nke ọma ma na-agba ọsọ nke ọma na ọsọ ọsọ mgbe niile. A na-achịkwa moto na-enweghị ahịhịa site na ntụgharị ugboro dijitalụ. A na-agbanwe AC mbụ ka ọ bụrụ DC, wee gbanwee DC ka ọ bụrụ AC. A na-achịkwa ọsọ ahụ site na mgbanwe ugboro ugboro. Ya mere, moto ndị na-enweghị brush na-agba ọsọ na-enweghị isi mgbe ha na-amalite na braking, na-enwe nnukwu mkpọtụ, na naanị mgbe ọsọ na-adị mgbe niile ka ha na-agba ọsọ nke ọma.
▶ 4. Elu njikwa ziri ezi nke DC brush moto:
A na-ejikarị moto brush DC eme ihe yana igbe gear na decoder, nke na-eme ka mmepụta moto dị ukwuu ma na-achịkwa izi ezi dị elu. Izizi njikwa ahụ nwere ike iru 0.01 mm, ma nwee ike ịkwụsị ịkwagharị akụkụ ihe fọrọ nke nta ka ọ bụrụ ebe ọ bụla ịchọrọ. Ngwa igwe niile ziri ezi na-eji moto DC jikwaa izi ezi.
▶ 5. DC brush moto nwere ọnụ ala dị ala na mfe mmezi.
N'ihi usoro ya dị mfe, ọnụ ahịa mmepụta dị ala, ọtụtụ ndị na-emepụta ihe na teknụzụ tozuru okè, a na-eji moto brush DC eme ihe na nke dị ọnụ ala. Teknụzụ moto na-enweghị brush akabeghị aka, ọnụahịa ahụ dị elu yana oke ngwa nwere oke. Ekwesịrị iji ya mee ihe na akụrụngwa ọsọ mgbe niile, dị ka ntụ oyi na-agbanwe ugboro ugboro, friji, wdg. Enwere ike dochie naanị mmebi moto na-enweghị ahịhịa.
▶ 6. nnyonye anya dị ala, enweghị ahịhịa:
Moto na-enweghị brush na-ewepụ brushes na mgbanwe kachasị kpọmkwem bụ enweghị ọkụ eletrik na-emepụta mgbe moto na-enweghị brush na-agba ọsọ, nke na-ebelata nnyonye anya nke ọkụ eletrik na akụrụngwa redio dịpụrụ adịpụ.
