Zvinoenderana nemugadziri wemota dzevibration, musimboti wekushanda wemota yeDCndeyekushandura simba remagetsi rinoshanduka rinogadzirwa nekudzikiswa kwesimba mu armature coil kuita simba remagetsi rinoshanduka parinotorwa kubva kumagumo ebhurashi ne commutator uye commutator action yebhurashi.
Kubva pabasa re commutator kutsanangura: bhurashi hariwedzere dc voltage, ne prime mover ichidhonza armature counterclockwise constant speed rotation, mativi maviri e coil akacheka mutsetse wesimba remagineti pasi pe polarity yakasiyana ye magnetic pole, uye umo induction yakagadzira electromotive force, electromotive force direction zvichienderana nemutemo weruoko rwerudyi kuti uone.
Sezvo armature ichitenderera nguva dzose, zvinodikanwa kuti kondakita inotakura magetsi ishandiswe kumucheto we coil ab neCD mumunda wemagineti kuti icheke mitsetse yesimba pasi pematanda eN neS, kunyange zvazvo kutungamira kwesimba remagetsi rinokonzereswa pamucheto wega wega we coil uye mukati me coil yese kuchichinjana.
Simba remagetsi rinokonzereswa mu coil isimba remagetsi rinochinjana, nepo simba remagetsi riri kumagumo kwebhurashi A neB riri simba remagetsi rinokonzereswa nemagetsi zvakananga.
Nekuti, mukutenderera kwe armature, zvisinei nekuti armature inotenderera kupi, nekuda kwe commutator uye brush commutator action, electromotive force inokonzerwa ne brush A kuburikidza ne commutator blade inogara iri electromotive force iri kumucheto kwe coil ichicheka n-pole magnetic field line. Saka, brush A inogara iine A positive polarity.
Nenzira imwecheteyo, bhurashi B inogara iine polarity isina kunaka, saka mugumo webrashi unogona kutungamira kune simba remagetsi rinotenderera risingaperi asi rakakura zvakasiyana. Kana huwandu hwema coils pasi pedanda rega rega hukawedzerwa, mwero wekutenderera kwemhepo unogona kuderedzwa uye simba remagetsi rinotenderera re dc rinogona kuwanikwa.
Aya ndiwo mashandiro anoita mamota eDC. Izvi zvinoratidzawo kuti mota yesub-dc inogadzira maAC ine commutator.
Zvichienderana nekuunzwa kwevagadziri vemagetsi emagetsi, kubva pamamiriro ezvinhu emagetsi, mota yeDC inogona kushanda semota inomhanya, inogonawo kumhanyiswa sejenareta, asi zvirambidzo zvakasiyana.
Pamigumo miviri yemabhurashi emota yeDC, wedzera voltage yeDC, isa simba remagetsi mu armature, simba remagetsi rinobuda kubva mumota, dhonza michina yekugadzira, simba remagetsi musimba remagetsi wobva wava mota;
Kana prime mover ikashandiswa kudhonza armature yemota yedc, uye bhurashi rikasawedzera dc voltage, ipapo mugumo webhurashi unogona kutungamira kudc electromotive force sesimba remagetsi redc, iro rinogona kuburitsa simba remagetsi. Mota iyi inoshandura simba remakanika kuita simba remagetsi uye inova mota yejenareta.
Pfungwa yekuti mota imwe chete inogona kushanda semota yemagetsi kana sejenareta. Mudzidziso yemota inonzi pfungwa inodzoserwa.
