Kodi Commutator ndi chiyani: Zomangamanga ndi Ntchito Zake

Thewapaulendochitha kufotokozedwa ngati chosinthira chamagetsi mumtundu wina wa ma jenereta komanso ma mota. Izi zimagwiritsidwa ntchito makamaka kutembenuza mayendedwe apano pakati pa dera lakunja & rotor. Imakhala ndi silinda yokhala ndi zigawo zingapo zolumikizirana zitsulo zomwe zagona pamakina ozungulira. Maburashi kapena zolumikizira zamagetsi zimapangidwa ndi makina osindikizira a kaboni pafupi ndi cholumikizira, kupanga mawonekedwe otsetsereka ndi magawo otsatizana a commutator pomwe ikuzungulira. Mapiritsi a armature amagwirizana ndi zigawo zawapaulendo.

Kugwiritsa ntchito kwa ma commutators kumaphatikizapo makina a DC (mwachindunji) monga ma jenereta a DC, ma mota ambiri a DC, komanso ma mota onse. Mugalimoto ya DC, woyendetsa amapereka magetsi pamakona. Pakusintha kolowera komweko mkati mwa ma windings ozungulira theka lililonse, torque (mphamvu yozungulira yokhazikika) idzapangidwa.

CommutatorKumanga ndi Ntchito

Kupanga ndi kugwira ntchito kwa awapaulendondi, cholumikizira chimatha kumangidwa ndi mipiringidzo yolumikizana yomwe imayikidwa chakumapeto kwa makina ozungulira a DC, ndikulumikizana ndi makhoma ankhondo. Pamene shaft ikutembenuka, woyendetsa amatha kusintha kayendedwe kameneka mkati mwa mafunde. Kwa mapindikidwe enaake a zida, pomwe shaft ikamaliza kutembenuka kwa theka, ndiye kuti makhotawo adzalumikizidwa kuti aperekedwe pano motsata njira yoyamba.

Mu injini ya DC, mphamvu yamagetsi imapangitsa kuti mphamvu ya maginito igwiritse ntchito mphamvu yozungulira, apo ayi torque pamwamba pa mafunde kuti izungulire. Mu jenereta ya DC, torque yamakina imatha kuyikidwa molunjika ku shaft kuti musunge mafunde oyenda ndi maginito osasunthika, kulimbikitsa mphamvu mkati mwa mafunde. Pazigawo ziwirizi, Nthawi zina, oyendetsa amatha kusintha njira yomwe ikuyenda pakalipano ponseponse kuti mafunde akuyenda mkati mwa dera lomwe ali kunja kwa makina azikhala mbali imodzi yokha.
