Hobaneng ha commutator e hiroa mechini ea DC?

A mopalamie sebelisoa mecheng ea DC (ho toba hona joale), joalo ka li-motors tsa DC le lijenereithara tsa DC, ka mabaka a 'maloa a bohlokoa:

Phetoho ea AC ho ea ho DC: Ka lijenereithara tsa DC, mopalami o sebeletsa ho fetolela motlakase o mong (AC) o kentsoeng mapheong a lihlomo hore e be tlhahiso e tobileng ea hajoale (DC). Ha sesebelisoa sa letsoho se ntse se potoloha ka har'a matla a khoheli, mopalami o khutlisa tsela ea hona joale ho coil e 'ngoe le e' ngoe ea lihlomo ka nako e loketseng, ho netefatsa hore tlhahiso ea hona joale e phallang ka tsela e le 'ngoe.

Tlhokomelo ea Tataiso ea Hona Joale: Ho li-motor tsa DC, mopalami o etsa bonnete ba hore tataiso ea hona joale ka mapheo a li-armature e lula e le teng ha rotor e ntse e potoloha ka har'a matla a khoheli. Phallo ena e sa lebelloang ea hona joale e hlahisa torque e tsoelang pele e tsamaisang ho potoloha ha koloi.

Moloko oa Torque: Ka ho fetola nako le nako tsela ea hona joale mapheong a lihlomo, mopalami o hlahisa torque e sa feleng ho li-motor tsa DC. Torque ena e thusa motlakase ho hlola inertia le meroalo e ka ntle, e bakang ho potoloha ha bonolo le ho tsoelang pele.

Thibelo ea Li-Armature Shorts: Likarolo tsa bapalami, tse koaletsoeng ho tloha ho tse ling, li thibela li-circuits tse khutšoane lipakeng tsa li-coil tsa armature tse haufi. Ha mopalami a ntse a potoloha, e etsa bonnete ba hore coil e 'ngoe le e' ngoe ea lihlomo e boloka ho kopana ha motlakase le potoloho e ka ntle ka li-brushes ha e ntse e qoba ho kopana le li-coil tsa boahelani.

Taolo ea Lebelo le Torque: Moralo oa commutator, hammoho le palo ea likarolo le tlhophiso ea maqhubu, e lumella ho laola lebelo le litšobotsi tsa torque tsa mechini ea DC. Ka lintlha tse fapaneng tse kang motlakase o kentsoeng le matla a matla a khoheli, li-operators li ka fetola lebelo le torque e hlahisoang ke enjene kapa jenereithara hore e lumellane le litlhoko tse itseng.

Ka kakaretso, themopalamie bapala karolo ea bohlokoa ts'ebetsong ea mechini ea DC ka ho thusa phetolo ea matla a motlakase hore e be matla a mochini (ka li-motors) kapa ka tsela e fapaneng (ka lijenereithara) ha e ntse e boloka likhokahano tsa motlakase tse tšepahalang le taolo holim'a tataiso le boholo ba phallo ea hajoale.
