Hapana musiyano uripo pakati pemota yeDC brush yecarbon nemota yeDC brush yebrush, semabhurashi anoshandiswa muMota dzeDCkazhinji mabhurashi ecarbon. Zvisinei, kuti zvive pachena mune dzimwe nzvimbo, maviri aya anogona kutaurwa uye kuenzaniswa nemamwe marudzi emota. Inotevera itsananguro yakadzama:

Bhurasha DC Motor

• Nheyo Yekushanda: Mota yeDC yakakweshwa inoshanda pamisimboti ye electromagnetic induction uye Ampere's rule6. Ine zvikamu zvakaita se stator, rotor, mabhurashi, uye commutator. Kana DC power source ichipa simba kumota kuburikidza nemabhurashi, stator inogadzira static magnetic field, uye rotor, yakabatana nepower source kuburikidza nemabhurashi ne commutator, inoumba rotating magnetic field. Kubatana pakati pe rotation magnetic field ne stator field kunogadzira electromagnetic torque, iyo inosunda mota kuti itenderere. Munguva yekushanda, mabhurashi anotsvedza pa commutator kuti adzorere current uye arambe achitenderera mota6.
• Hunhu hweMagadzirirwo: Ine chimiro chakareruka, chinosanganisira stator, rotor, mabhurashi, uye commutator. Stator inowanzo gadzirwa nemapepa esimbi esilicon ane laminated ane mawindings akatenderedza. Rotor ine simbi ne windings, uye mawindings akabatana nemagetsi kuburikidza nemabhurashi6.
• Zvakanakira: Ine magadzirirwo ari nyore uye inodhura zvishoma, zvichiita kuti zvive nyore kugadzira nekugadzirisa. Inewo mashandiro akanaka ekutanga uye inogona kupa torque yakakura yekutanga.
• Zvakashata: Kukweshana uye kupenya pakati pemabhurashi necommutator panguva yekushanda kunoita kuti mota iparare, zvichideredza kushanda zvakanaka uye hupenyu hwayo. Uyezve, mashandiro ayo ekudzora kumhanya haana kunaka, zvichiita kuti zviome kuwana kudzora kumhanya kwakaringana6.

Kabhoni Bhurashi DC Mota

• Nheyo Yekushanda: Mota yeDC yebhurashi rekabhoni inonyanya kuve mota yeDC yakakweshwa, uye nheyo yayo yekushanda yakafanana neyemota yeDC yakakweshwa yakatsanangurwa pamusoro apa. Bhurashi rekabhoni rinosangana necommutator, uye sezvo commutator ichitenderera, bhurashi rekabhoni rinoramba richichinja divi remagetsi ari mu rotor coil kuti ive nechokwadi chekuti rotor inotenderera nguva dzose.
• Hunhu hweMaumbirwo: Chimiro chacho chakafanana nechemota yeDC yakakweshwa, kusanganisira stator, rotor, carbon brush, uye commutator. Bhurashi recarbon rinowanzogadzirwa negraphite kana musanganiswa wegraphite nehupfu hwesimbi, iyo ine conductivity yakanaka yemagetsi uye inozvizora yega, zvichideredza kupera nekubvaruka pakati pebhurashi necommutator kusvika pamwero wakati.
• Zvakanakira: Bhurasho rekabhoni rine hunhu hwakanaka hwekuzvizora uye hunodzivirira kupera simba, izvo zvinogona kuderedza mari yekutsiva nekugadzirisa bhurasho. Rinewo kufambisa magetsi kwakanaka uye rinogona kuona kuti mota inoshanda zvakanaka.
• Zvakashata: Kunyangwe bhurashi rekabhoni risingapfeki zviri nani pane mamwe mabhurashi akajairwa, richiri kuda kutsiviwa nguva nenguva. Pamusoro pezvo, kushandiswa kwemabhurashi ekabhoni kunogonawo kugadzira upfu hwekabhoni, hunoda kucheneswa nguva nenguva kudzivirira kuti risakanganise mashandiro emota.
