Akukho mehluko phakathi kwemoto ye-DC brush yekhabhoni kanye nemoto ye-DC brush empeleni, njengoba amabhulashi asetshenziswa kuAma-motor e-DCngokuvamile amabhulashi e-carbon. Kodwa-ke, ukuze kucace kwezinye izimo, lokhu okubili kungashiwo futhi kuqhathaniswe nezinye izinhlobo zama-motor. Okulandelayo incazelo eningiliziwe:

I-Brashi DC Motor

• Isimiso Sokusebenza: I-motor ye-DC ebhulashiwe isebenza ngezimiso zokungeniswa kwe-electromagnetic kanye nomthetho we-Ampere6. Yakhiwe yizingxenye ezifana ne-stator, i-rotor, amabhulashi, kanye ne-commutator. Lapho umthombo wamandla we-DC unikeza amandla ku-motor ngamabhulashi, i-stator ikhiqiza insimu yamagnetic engaguquki, kanti i-rotor, exhunywe kumthombo wamandla ngamabhulashi kanye ne-commutator, yakha insimu yamagnetic ejikelezayo. Ukusebenzisana phakathi kwensimu yamagnetic ejikelezayo kanye nensimu ye-stator kukhiqiza i-torque ye-electromagnetic, eqhuba i-motor ukuthi ijikeleze. Ngesikhathi sokusebenza, amabhulashi ayashelela ku-commutator ukuze abuyisele emuva amandla futhi agcine ukujikeleza okuqhubekayo kwe-motor6.
• Izici Zesakhiwo: Inesakhiwo esilula, ikakhulukazi esihlanganisa i-stator, i-rotor, amabhulashi, kanye ne-commutator. I-stator ivame ukwenziwa ngamashidi ensimbi e-silicon aqinisiwe anama-windings azungezile. I-rotor ine-core yensimbi nama-windings, kanti ama-windings axhunywe kugesi ngamabhulashi6.
• Izinzuzo: Inezinzuzo zesakhiwo esilula kanye nezindleko eziphansi, okwenza kube lula ukukhiqiza nokunakekela. Iphinde ibe nokusebenza okuhle kokuqala futhi inganikeza i-torque enkulu yokuqalisa6.
• Okubi: Ukungqubuzana kanye nokuqhuma phakathi kwamabhulashi kanye ne-commutator ngesikhathi sokusebenza kuholela ekugugeni nasekudabukeni, kunciphisa ukusebenza kahle kwemoto kanye nesikhathi sayo sokuphila. Ngaphezu kwalokho, ukusebenza kwayo kokulawula isivinini kuphansi kakhulu, okwenza kube nzima ukufeza ukulawula isivinini okunembile6.

Imoto ye-DC Brush ye-Carbon

• Isimiso Sokusebenza: Imoto ye-DC brush carbon empeleni iyimoto ye-DC ebhulashiwe, futhi isimiso sayo sokusebenza sifana nemoto ye-DC ebhulashiwe echazwe ngenhla. Ibhulashi le-carbon lithintana ne-commutator, futhi njengoba i-commutator ijikeleza, ibhulashi le-carbon lishintsha njalo indlela yamanje ku-rotor coil ukuqinisekisa ukujikeleza okuqhubekayo kwe-rotor.
• Izici Zesakhiwo: Isakhiwo sifana kakhulu nesemoto ye-DC exutshwe ngokujwayelekile, okuhlanganisa i-stator, i-rotor, i-carbon brush, kanye ne-commutator. Ibhulashi le-carbon ngokuvamile lenziwa nge-graphite noma ingxube ye-graphite kanye ne-metal powder, ene-conductivity enhle kagesi kanye nezakhiwo zokuzigcoba, okunciphisa ukuguguleka phakathi kwebhulashi kanye ne-commutator ngezinga elithile.
• Izinzuzo: Ibhulashi lekhabhoni linezakhiwo ezinhle zokuzigcoba futhi ezingagugi, ezinganciphisa ukuvama kokushintsha ibhulashi kanye nezindleko zokulungisa. Liphinde libe nokuqhuba kahle kukagesi futhi lingaqinisekisa ukusebenza kahle kwenjini.
• Okubi: Nakuba ibhulashi lekhabhoni linamandla okuguga kangcono kunezinye izibhulashi ezivamile, kusadingeka lishintshwe njalo. Ngaphezu kwalokho, ukusetshenziswa kwezibhulashi zekhabhoni kungakhiqiza nempuphu yekhabhoni, okudingeka ihlanzwe njalo ukuze ingathinti ukusebenza kwenjini.
