The commutator ndi gawo lofunikira mu aDC motere, yomwe imagwiritsidwa ntchito makamaka kuti isinthe njira yapano, potero kuzindikira kuyendayenda kutsogolo ndi kumbuyo kwa galimoto. Mu ntchito yaSIMO njinga yamoto, cholumikizira chimakhala ndi gawo lofunikira, ndipo magwiridwe ake amakhudza mwachindunji magwiridwe antchito ndi kukhazikika kwa mota ya DC.
The commutator nthawi zambiri imakhala ndi mapepala azitsulo omwe ali pafupi kwambiri ndi maburashi a galimoto. Pamene injini ikuzungulira, maburashi amalumikizana ndi mapepala achitsulo pa commutator, motero amasintha njira yapano. Makina osinthirawa amathandizira kuti injiniyo izizungulira mosalekeza popanda kuyimitsa chifukwa chakusintha komwe kumayendera.
Mapangidwe a commutator ndi osakhwima komanso ovuta, ndipo akuyenera kuwonetsetsa kuti atha kugwirabe ntchito mokhazikika komanso modalirika pa liwiro lalikulu. Chifukwa chake, kusankha kwazinthu, kulondola kwa kukonza ndi kukhazikitsa kwa commutator ndikofunikira kwambiri. Nthawi zambiri, commutator imapangidwa ndi zitsulo zokhala ndi zinthu zabwino zowongolera kuti zitsimikizire kuyenda bwino kwapano. Panthawi imodzimodziyo, pamwamba pake amafunika kuthandizidwa mwapadera kuti apititse patsogolo kukhudzana ndi maburashi ndi kuchepetsa kuvala ndi zowawa.
Udindo wa motor commutator sikuti umangosintha komwe ukupita, ungathenso kusintha liwiro ndi torque ya mota pamlingo wina. Mwa kusintha magawo apangidwe a commutator, magwiridwe antchito agalimoto amatha kukonzedwa. Mwachitsanzo, kuwonjezera kuchuluka kwa mapepala achitsulo a commutator kumatha kukulitsa liwiro la mota, pomwe kusintha mawonekedwe ndi makonzedwe azitsulo kumatha kukhudza kutulutsa kwamoto. M'magwiritsidwe ntchito, ma commutators amagalimoto amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi, monga magalimoto amagetsi, zida zamagetsi, ndi zida zapakhomo. Zipangizozi zimafuna injini kuti izitha kuzungulira kutsogolo ndikubwerera kumbuyo kuti ikwaniritse ntchito zosiyanasiyana, ndipo commutator ndiye chinthu chofunikira kwambiri kuti akwaniritse ntchitoyi.
Komabe, woyendetsa galimoto amathanso kukhala ndi zovuta pakagwiritsidwe ntchito, monga kuvala komanso kusalumikizana bwino. Mavutowa angayambitse kuwonongeka kwa galimoto kapena kuyambitsa kulephera. Chifukwa chake, kuyang'anira ndi kukonza nthawi zonse kwa commutator ndikofunikira kuti mutsimikizire kuti injiniyo ikuyenda bwino.
Mwachidule, commutator ndi gawo lofunika kwambiri mugalimoto yamagetsi. Imazindikira kusuntha kwagalimoto kutsogolo ndi kumbuyo posintha komwe akulowera ndikusintha magwiridwe antchito mpaka pamlingo wina. Kumvetsetsa mfundo ndi ntchito ya commutator ndikofunikira kwambiri pakugwiritsa ntchito moyenera ndikukonza mota.
