Kodi commutator ndi chiyani?

Commutator ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito muMota ya DCNtchito yake ndikusintha njira yamagetsi mu mota, potero kusintha njira yozungulira mota. Mu mota ya DC, njira yamagetsi iyenera kusinthidwa nthawi ndi nthawi kuti injiniyo isunge njira yozungulira. Ntchito ya commutator ndikusintha nthawi zonse njira yamagetsi pamene mota ikuzungulira, kuti motayo ipitirire kuzungulira mokhazikika.

Mfundo yaikulu ya commutator ndikugwiritsa ntchito ma switch amakina ndi ma contact amagetsi kuti asinthe njira yoyendera magetsi. Pamene mota ikuzungulira, commutator imalamulira kuyatsa ndi kutseka kwa magetsi malinga ndi malo ndi njira yozungulira ya rotor, motero imasintha njira ya magetsi. Mtundu uwu wa commutator wamakina nthawi zambiri umagwiritsidwa ntchito mu ma mota ang'onoang'ono a DC amphamvu, monga zipangizo zapakhomo, zida zazing'ono zamakina, ndi zina zotero.

Mu mota yachikhalidwe ya DC, commutator nthawi zambiri imakhala ndi zigawo zingapo: armature, poles, commutator ndi maburashi. Armature ndi gawo lozungulira la mota, ndipo poles zamaginito ndi gawo la stator la mota. Commutator imakhala ndi ma switch amakina ndi ma contact amagetsi omwe amasintha njira ya magetsi. Burashi ndi gawo lomwe limalumikiza magetsi ndi mota, ndikulowetsa magetsi mu coil ya mota kudzera mu burashi.

Kuwonjezera pa makina oyendera magetsi, ma DC motors amakono amagwiritsanso ntchito kwambiri ukadaulo wamagetsi. Ukadaulo wamagetsi woyendera magetsi umagwiritsa ntchito chowongolera zamagetsi kusintha njira yamagetsi, potero kuzindikira kusintha kwa injini. Poyerekeza ndi makina oyendera magetsi, ukadaulo wamagetsi woyendera magetsi uli ndi kulondola kwakukulu komanso kudalirika, ndipo ukhoza kukwaniritsa kulamulira kolondola kwa kayendedwe ka magetsi. Chifukwa chake, wagwiritsidwa ntchito kwambiri m'mapulogalamu ena omwe amafunikira kulondola kwakukulu kwa kayendedwe ka magetsi.

Choyendetsa galimoto chimagwira ntchito yofunika kwambiri pa ma DC motors, zomwe zimakhudza magwiridwe antchito a injini, magwiridwe antchito ake, komanso kudalirika kwake. Choyendetsa galimoto chabwino chingatsimikizire kuti injiniyo ikugwira ntchito bwino komanso mokhazikika, ndikuwonjezera moyo wa injiniyo. Chifukwa chake, kapangidwe, kupanga ndi kusamalira choyendetsa galimotoyo ndikofunikira kwambiri.

Ndi kupita patsogolo kosalekeza kwa ukadaulo, kapangidwe ndi kupanga ukadaulo wa magalimoto oyendetsa ...
