1. Mota yeDC yakakweshwa

Mumamota ane brushed izvi zvinoitwa ne rotary switch pa shaft yemota inonzi commutator. Inoumbwa nesilinda inotenderera kana diski yakakamurwa kuita zvikamu zvakawanda zvesimbi pa rotor. Zvikamu zvakabatana ne conductor windings pa rotor. Ma static contacts maviri kana anopfuura anonzi ma brushes, akagadzirwa ne soft conductor senge graphite, anodzvanya pa commutator, zvichiita kuti sliding electrical contact nezvikamu zvinotevedzana sezvo rotor ichitenderera. Ma brushes anopa electric current kuma windings nenzira yakasarudzwa. Sezvo rotor ichitenderera, commutator inosarudza ma windings akasiyana uye directional current inoiswa kune imwe winding zvekuti rotor's magnetic field inoramba yakakanganiswa ne stator uye inogadzira torque munzira imwe chete.

2. Mota yeDC isina bhurashi

Mumamota eDC asina mabhurashi, sisitimu yemagetsi yeservo inotsiva macontact emechanical commutator. Sensor yemagetsi inoona kona yerotor uye inodzora maswitch e semiconductor akadai se transistors anochinja magetsi kuburikidza nema windings, kungave achidzosera divi remagetsi kana, mune mamwe mamota achiidzima, pakona chaiyo kuitira kuti ma electromagnets agadzire torque kune rimwe divi. Kubviswa kwe sliding contact kunobvumira mamota asina mabhurashi kuti ave nekukweshana kushoma uye hupenyu hwakareba; hupenyu hwavo hwekushanda hunongogumira chete nehupenyu hwema bearingers avo.

Mamota eDC akabhurwa anokura simba guru kana akasamira, achidzikira zvakanyanya sezvo kumhanya kuchiwedzera. Zvimwe zvipingamupinyi zvemamota akabhurwa zvinogona kukundwa nemamota asina mabhurwa; zvinosanganisira kushanda zvakanaka uye kusanyanya kukanganiswa nekusakara kwemuchina. Mabhenefiti aya anouya nekuda kwekushandisa michina yekudzora isinganyanyi kuomarara, yakaoma, uye inodhura zvakanyanya.

Mota isina mabhurashi ine magineti anogara kwenguva refu anotenderera akapoteredza armature yakatarwa, zvichibvisa matambudziko ane chekuita nekubatanidza magetsi kune armature inofamba. Chinodzora magetsi chinotsiva commutator assembly yemota yeDC yakakweshwa, iyo inogara ichichinja phase kuenda kumawindings kuti mota irambe ichitenderera. Chinodzora chinoita zvakafanana nekugovera simba nenguva nekushandisa solid-state circuit pane commutator system.

Mota dzisina mabhurashi dzine zvakanakira zvakawanda pamusoro pemota dzeDC dzakarukwa, zvinosanganisira torque yakakwira nehuremu, kuwedzera kushanda zvakanaka kunogadzira torque yakawanda pa watt, kuwedzera kuvimbika, kudzikira kweruzha, hupenyu hurefu nekubvisa kukanganiswa kwebhurashi ne commutator, kubvisa ma ionizing sparks kubva mumagetsi.
commutator, uye kuderedzwa kwe electromagnetic interference (EMI). Pasina ma windings pa rotor, haapinzwe pasi pe centrifugal forces, uye nekuti ma windings anotsigirwa ne housing, anogona kutonhodzwa ne conduction, pasina kuda mhepo iri mukati me motor kuti itonhodze. Izvi zvinorevawo kuti mukati me motor inogona kuvharwa zvachose uye kudzivirirwa kubva kutsvina kana zvimwe zvinhu zvekunze.

Kuchinja kwemota isina brush kunogona kuitwa musoftware uchishandisa microcontroller, kana kuti kunogona kuitwa uchishandisa analog kana digital circuits. Kuchinja kwemota uchishandisa electronics pachinzvimbo chemabhurashi kunobvumira kuchinjika kukuru uye kugona kusingawanikwe nemamota eDC akapfava, kusanganisira kudzora kumhanya, microstepping operation yekudzora kufamba zvishoma nezvishoma, uye holding torque kana yakamira. Controller software inogona kugadziriswa zvichienderana nemota chaiyo iri kushandiswa muapplication, zvichikonzera kushanda zvakanaka kwekuchinja kwemota.

Simba guru rinogona kushandiswa pamota isina brushless rinongogumira pakupisa chete; [citation needed] kupisa kwakanyanya kunoshayisa simba magineti uye kunokuvadza insulation yemawindings.

Pakushandura magetsi kuita simba remuchina, mota dzisina mabhurashi dzinoshanda zvakanyanya kupfuura mota dzakakweshwa nekuda kwekushaikwa kwemabhurashi, izvo zvinoderedza kurasikirwa nesimba remuchina nekuda kwekukweshana. Kushanda zvakanaka kwakanyanya munzvimbo dzisina mutoro uye dzisina mutoro wakawanda dzemuchina.

Nzvimbo nezvinodiwa nevagadziri vanoshandisa mota dzeDC dzisina mabhurashi zvinosanganisira kushanda pasina kugadzirisa, kumhanya kwakanyanya, uye kushanda uko kuputika kwemoto kune njodzi (kureva nzvimbo dzinoputika) kana kuti kunogona kukanganisa michina inobatwa nemagetsi.

Kugadzirwa kwemota isina brush kwakafanana nemota yestepper, asi mota dzine musiyano wakakosha nekuda kwekusiyana kwekushandiswa uye mashandiro. Kunyange hazvo mota dzestepper dzichiwanzo miswa nerotor iri panzvimbo yakatsanangurwa yekona, mota isina brush inowanzo gadzirirwa kugadzira kutenderera kunogara kuripo. Mhando dzese dzemota dzinogona kunge dziine sensor yerotor position yemhinduro dzemukati. Mota yestepper nemota isina brush yakagadzirwa zvakanaka inogona kuchengetedza finite torque pa zero RPM.
