Commutator mudziyo wemagetsi unoshandiswa muMota yeDCBasa rayo nderekuchinja mafambiro emagetsi mumota, nokudaro ichichinja mafambiro emagetsi emota. Mumota yeDC, mafambiro emagetsi anofanira kuchinjwa nguva nenguva kuti mota irambe ichitenderera. Basa recommutator nderekuchinja mafambiro emagetsi nguva nenguva kana mota ichitenderera, kuitira kuti mota irambe ichitenderera zvakadzikama.
Nheyo huru yecommutator ndeyekushandisa seti yemaswichi emakanika uye macontact emagetsi kuti ichinje mafambiro emagetsi. Kana mota ichitenderera, commutator inodzora kubatidzwa nekubviswa kwemagetsi zvichienderana nenzvimbo uye mafambiro ekutenderera kwerotor, nokudaro ichichinja mafambiro emagetsi. Rudzi urwu rwecommutator yemakanika runowanzo shandiswa mumamota madiki eDC ane simba, akadai semidziyo yemumba, michina midiki yemakanika, nezvimwewo.
Mumota yeDC yechinyakare, commutator inowanzo kuve nezvikamu zvakati wandei: armature, poles, commutator nemabhurashi. Armature chikamu chinotenderera chemota, uye poles dzemagineti chikamu che stator chemota. Commutator ine seti yemaswichi emakanika uye macontact emagetsi ayo kutungamira kwemagetsi kunochinjwa. Bhurashi chikamu chinobatanidza simba remagetsi nemota, uye chinoisa magetsi mu coil yemota kuburikidza nebhurashi.
Kuwedzera kuma "commutator" emakanika, ma "DC motors" emazuva ano anoshandisawo tekinoroji ye "electronic commutation". Tekinoroji ye "electronic commutation" inoshandisa "electronic controller" kushandura mafambiro emagetsi, nokudaro zvichiita kuti mota ikwanise kuchinja magetsi. Kana ichienzaniswa nema "commutator" emakanika, tekinoroji ye "electronic commutation" ine kururama kwakanyanya uye kuvimbika, uye inogona kuwana kudzora kwe "commutation" kwakanyatsojeka. Saka, yakashandiswa zvakanyanya mune mamwe mashandisirwo anoda "high commutation accuracy".
Commutator inoita basa guru mumota dzeDC, zvichikanganisa mashandiro emota, kushanda kwayo zvakanaka uye kuvimbika kwayo. Commutator yakanaka inogona kuona kuti mota inoshanda zvakanaka uye zvakadzikama, uye inowedzera hupenyu hwemota. Saka, dhizaini, kugadzirwa uye kugadziriswa kwecommutator kwakakosha zvikuru.
Nekufambira mberi kuri kuita tekinoroji, dhizaini nekugadzirwa kwemagetsi ekufambisa mota dziri kuramba dzichivandudzika, uye matekinoroji matsva ekufambisa mota emagetsi ari kuramba achibuda, zvichiita kuti kushandiswa kwemagetsi ekufambisa mota mumagetsi eDC kuve nyore uye kwakavimbika. Mune ramangwana, sezvo tekinoroji yekufambisa mota ichikura, magetsi ekufambisa mota acharamba achivandudzwa uye achigadziriswa kuti asvike pakuchinja kwezvinodiwa zvekushandisa.
Muchidimbu, sechikamu chakakosha chemota yeDC, commutator inoshandiswa kushandura mafambiro emagetsi emota, nokudaro ichichinja mafambiro ekutenderera kwemota. Kuburikidza netekinoroji yekuchinja kwemagetsi kana yemagetsi, commutator inogona kuve nechokwadi chekuti mota inoshanda zvakanaka uye inoshandiswa zvakanyanya mumidziyo yemumba, michina yeindasitiri, mota nedzimwe nzvimbo. Sezvo tekinoroji ichiramba ichikura, dhizaini yemagetsi uye matekiniki ekugadzira ari kuramba achivandudzwa kuti asangane nezvinodiwa zvekushandisa zvinochinja.
