Iko hakuna mutsauko pakati pekabhoni brashi DC mota uye brashi DC mota mune essence, semabhurashi anoshandiswa mukatiDC motakazhinji kabhoni brushes. Nekudaro, nekuda kwekujekesa mune mamwe mamiriro, izvo zviviri zvinogona kutaurwa uye zvichienzaniswa nemamwe marudzi emotor. Inotevera itsanangudzo yakadzama:

Brush DC Motor

• Kushanda Nheyo: Iyo brushed DC mota inoshanda pamisimboti yemagetsi induction uye mutemo weAmpere6. Iyo ine zvinhu zvakaita se stator, rotor, mabhurashi, uye commutator. Kana magetsi eDC achipa simba kumota kuburikidza nemabhurashi, stator inogadzira static magineti, uye rotor, yakabatana kune simba sosi kuburikidza nemabhurashi uye commutator, inoumba inotenderera magineti. Iko kudyidzana pakati peinotenderera magineti nemunda we stator inoburitsa electromagnetic torque, iyo inotyaira mota kutenderera. Panguva yekushanda, mabhurashi anotsvedza pane inofambisa kudzosera kumashure uye kuchengetedza mota inotenderera ichitenderera6.
• Chimiro Hunhu: Iyo ine chimiro chakareruka, kunyanya kusanganisira stator, rotor, mabhurashi, uye commutator. Iyo stator inowanzogadzirwa nelaminated silicon simbi mapepa ane windings ronda kumativi. Iyo rotor inoumbwa nesimbi core uye windings, uye windings yakabatana kune magetsi ekupa kuburikidza nemabhurashi6.
• Zvakanakira: Iine mabhenefiti echimiro chakareruka uye mutengo wakaderera, zvichiita kuti zvive nyore kugadzira nekuchengetedza. Iyo zvakare ine yakanaka yekutanga kuita uye inogona kupa yakakura yakakura yekutanga torque6.
• Zvakaipa: Iko kupokana uye kupenya pakati pemabhurashi neanofambisa panguva yekushanda zvinotungamira mukupfeka uye kubvaruka, zvichideredza kushanda zvakanaka kwemota uye hupenyu. Uyezve, kuita kwayo kumhanya kwekutonga kwakashata, zvichiita kuti zviome kuwana chaiyo yekumhanyisa control6.

Carbon Brush DC Motor

• Kushanda Nheyo: Iyo kabhoni bhurashi DC mota inonyanya kubhuroshwa DC mota, uye nheyo yayo yekushanda yakafanana neyeiyo brashi DC mota inotsanangurwa pamusoro. Iyo kabhoni brashi inosangana neye commutator, uye sezvo commutator inotenderera, kabhoni brashi inoramba ichichinja kutungamira kweiyo ikozvino mu rotor coil kuti ive nechokwadi chekutenderera kutenderera kwe rotor.
• Chimiro Hunhu: Chimiro chakafanana neicho cheiyo general brushed DC mota, kusanganisira iyo stator, rotor, kabhoni brashi, uye commutator. Iyo kabhoni brashi inowanzogadzirwa negraphite kana musanganiswa wegraphite uye simbi poda, iyo ine yakanaka magetsi conductivity uye self-lubricating properties, kuderedza kupera uye kubvarura pakati pebhurashi uye commutator kusvika pamwero wakati.
• Zvakanakira: Iyo kabhoni bhurashi ine yakanaka yekuzvizora uye inodzivirira kupfeka zvinhu, izvo zvinogona kuderedza kuwanda kwekutsiva kwebhurashi uye mari yekugadzirisa. Iyo zvakare ine yakanaka conductivity yemagetsi uye inogona kuve nechokwadi chekushanda kwakanaka kwemota.
• Zvakaipa: Kunyangwe kabhoni brashi iine zvirinani kupfeka kuramba pane mamwe mabhurashi akajairwa, ichiri kuda kutsiviwa nguva nenguva. Mukuwedzera, kushandiswa kwekabhoni brushes kunogonawo kugadzira imwe carbon powder, iyo inoda kucheneswa nguva dzose kuti irege kukanganisa kushanda kwemotokari.
