Akukho mahluko phakathi kwemoto ye-DC brush yekhabhoni kunye nemoto ye-DC brush ngokwendalo, njengoko iibrashi zisetyenziswa kwiIimoto zeDCidla ngokuba ziibhrashi zekhabhoni. Nangona kunjalo, ukuze kucace kwezinye iimeko, ezi zimbini zinokukhankanywa kwaye zithelekiswe nezinye iintlobo zeemoto. Oku kulandelayo yingcaciso eneenkcukacha:

Ibhrashi yeMoto yeDC

• Umgaqo Wokusebenza: I-motor ye-DC exutyiweyo isebenza ngokwemigaqo yokungenisa i-electromagnetic kunye nomthetho we-Ampere6. Iqulathe izinto ezifana ne-stator, i-rotor, ii-brushes, kunye ne-commutator. Xa umthombo wamandla we-DC unika amandla kwi-motor ngee-brushes, i-stator ivelisa i-static magnetic field, kwaye i-rotor, eqhagamshelwe kumthombo wamandla ngee-brushes kunye ne-commutator, yenza i-rotor ejikelezayo. Ukusebenzisana phakathi kwe-rotary magnetic field kunye ne-stator field kuvelisa i-electromagnetic torque, eqhuba i-motor ukuba ijikeleze. Ngexesha lokusebenza, ii-brushes ziyatyibilika kwi-commutator ukuze zibuyisele umbane kwaye zigcine ukujikeleza okuqhubekayo kwe-motor6.
• Iimpawu zoLwakhiwo: Inesakhiwo esilula, esiquka ikakhulu i-stator, i-rotor, iibhrashi, kunye ne-commutator. I-stator idla ngokwenziwa ngamashiti esinyithi e-silicon afakwe i-laminated anee-windings ezijikelezileyo. I-rotor ine-iron core kunye nee-windings, kwaye ii-windings ziqhagamshelwe kumbane ngee-brushes6.
• Iingenelo: Inezinto ezilungileyo zesakhiwo esilula kunye nexabiso eliphantsi, okwenza kube lula ukuyenza nokuyigcina ikwimeko entle. Ikwasebenza kakuhle ekuqaliseni kwaye inokubonelela nge-torque enkulu yokuqalisa6.
• Iingxaki: Ukungqubana kunye nokuqhuma phakathi kweebhrashi kunye ne-commutator ngexesha lokusebenza kukhokelela ekugugeni nasekukrazukeni, kunciphisa ukusebenza kakuhle kwemoto kunye nobomi bayo. Ngaphezu koko, ukusebenza kwayo ekulawuleni isantya kuphantsi kakhulu, okwenza kube nzima ukufikelela kulawulo oluchanekileyo lwesantya6.

I-Carbon Brush DC Motor

• Umgaqo Wokusebenza: Imoto ye-DC yebhrashi yekhabhoni ngokuyintloko yimoto ye-DC ebhrashiweyo, kwaye umgaqo wayo wokusebenza uyafana nowemoto ye-DC ebhrashiweyo echazwe apha ngasentla. Ibhrashi yekhabhoni idibana ne-commutator, kwaye njengoko i-commutator ijikeleza, ibhrashi yekhabhoni itshintsha rhoqo indlela yamandla kwi-rotor coil ukuqinisekisa ukujikeleza okuqhubekayo kwe-rotor.
• Iimpawu zoLwakhiwo: Ulwakhiwo lufana kakhulu nolwemoto ye-DC exutywe ngokupheleleyo, kuquka i-stator, i-rotor, i-carbon brush, kunye ne-commutator. I-carbon brush idla ngokwenziwa nge-graphite okanye umxube we-graphite kunye nomgubo wesinyithi, one-conductivity yombane elungileyo kunye neempawu zokuzithambisa ngokwazo, okunciphisa ukuguguleka phakathi kwe-brush kunye ne-commutator ukuya kwinqanaba elithile.
• Iingenelo: Ibhrashi yekhabhoni ineempawu ezilungileyo zokuzithambisa kwaye ayigugi, nto leyo enokunciphisa iindleko zokutshintshwa kwebhrashi kunye nokugcinwa kwayo. Ikwanayo ne-conductivity entle yombane kwaye inokuqinisekisa ukusebenza kakuhle kwemoto.
• Iingxaki: Nangona ibhrashi yekhabhoni inokumelana nokuguguleka okungcono kunezinye iibhrashi eziqhelekileyo, kusafuneka itshintshwe rhoqo. Ukongeza, ukusetyenziswa kweebhrashi yekhabhoni kunokuvelisa umgubo wekhabhoni, ekufuneka ucocwe rhoqo ukuze ungachaphazeli ukusebenza kwenjini.
