[Kugawana Chidziwitso] Chifukwa chiyani mitengo yamagetsi yamagetsi ya DC nthawi zambiri imagwiritsa ntchito maginito amakona anayi?

The okhazikika maginito wothandiza exciter ndi mtundu watsopano wa kunja rotor DC okhazikika maginito galimoto.Mphete yake yozungulira yotsekera imayimitsidwa mwachindunji mutsinde.Pa mpheteyo pali mitengo 20 ya maginito.Nsapato iliyonse imakhala ndi nsapato yamtengo wapatali.Thupi la pole limapangidwa ndi zidutswa zitatu zamakona anayi.Amapangidwa ndi chitsulo cha maginito ndipo amamangirizidwa ndi guluu "914".Thupi lamtengowo limakulungidwa ndikulimbitsidwa ndi nthiti zagalasi zopanda latitude kuti apange manja oteteza.Thupi lililonse lamtengo ndi nsapato zamtengo zimapangidwa ndi zidutswa ziwiri za bangazitsulo zochepa.

Mugalimoto yamagetsi yamagetsi ya DC, magawo ena akamakhala osasinthika, maginito otsalira a maginito amakwera, maginito ang'onoang'ono, komanso kutsika kwa liwiro.Izi ndi zolondola.Kuchokera apa, mutha kudzifufuza nokha kuti ndi maginito ati a prototypes anu awiri omwe ali bwino.Maginito otsalira ndi aakulu.Ponena za mfundoyi, pamene magawo ena amakhala osasinthika, kukweza kwa maginito otsalira a maginito, kumapangitsa kuti maginito apite patsogolo pamtundu uliwonse wa galimoto.Malinga ndi mawonekedwe a liwiro la DC motor n=(U-IR)/CeΦ≈U/CeΦ, zitha kukhala kwambiri N'zosavuta kunena kuti Φ yayikulu, kutsitsa liwiro.Kutsika kwa liwiro, kuchepa kwapang'onopang'ono kosanyamula katundu, ndi kung'onozing'ono kosanyamula katundu.

Makokedwe okhoma okhoma a DC okhazikika maginito mota amagwirizana ndi makulidwe a maginito ndi mphamvu ya maginito.Ngati makulidwe angasinthe mphamvu ya maginito, idzakhala yoyenera.Pa msonkhano ndondomeko ya maginito ophatikizidwa okhazikika maginito galimoto, ngati pamanja Kugwiritsa ntchito guluu pamwamba pa maginito kumapangitsa kukhala kovuta kwa woyendetsa kuti agwire maginito.Nthawi yomweyo, chifukwa cha zolakwika muukadaulo womwe ulipo mukayika maginito mu kagawo, kukangana ndi khoma lolowera kudzachitika mosalephera.Kuphatikiza apo, guluu pamwamba pa chitsulo cha maginito chomwe chimagwiritsidwa ntchito pamanja ndipo chimakhala ndi malo ang'onoang'ono ophimba guluu amagawidwa mosagwirizana, zomwe zimapangitsa kuti asamamatire bwino, ndipo chitsulo cha maginito chimatha kugwa pakagwiritsidwa ntchito mtsogolo.
