1. DC Mota

M'maso mwansanga imachitika ndi state ya moretary pa shaft yamoto imayitanitsa womuthandiza. Imakhala ndi silinda yozungulira kapena disc yogawika magawo angapo achitsulo pa rotor. Zigawozi zimalumikizidwa ndi ochititsa ochititsa ena pa rotor. Machesi awiri kapena kupitilira apo otchedwa mabulashi, wopangidwa ndi wofewa monga graphite, akanikizire womuthandiza, ndikupanga kulumikizana kwamagetsi ndi zigawo zotsatizana monga rotor. Mabulosi osankha amapereka magetsi pamakono. Pamene Rotor imazungulira, imasankha minda yosiyanasiyana ndi njira yomwe ikuyendetsedwa ndi yomwe imaperekedwa kuti ikhale yopanda mphamvu kotero kuti maginito a rotor amakhalabe osokonekera.

Mu Motors DC Motors, makina amagetsi a seva yamagetsi m'malo mwa makina opanga makina. Sensor yamagetsi imazindikira mbali ya rotor ndikuwongolera stamictoct imasinthiratu kudzera munjira zomwe zimasinthiratu, potembenuza molondola kotero kuti electromagnets imapanga torque mbali imodzi. Kuthetsa kulumikizana komwe kumapangitsa kuti kukhale kopanda pake kukhala ndi mikangano pang'ono komanso moyo wautali; Moyo wawo wogwira ntchito umangokhala pa nthawi yonse ya moyo wawo.

Motor DC Motors zimapangitsa kuti chimbudzi chachikulu chikhale chokhazikika pomwe matembenuzidwe, ocheperako monga velicty amakwera. Mavuto ena ochepetsa misampha amatha kugonjetsedwa ndi zosinthika zopanda pake; Amaphatikizapo kuchita bwino kwambiri komanso kutsika kotsika pamakina oyendetsa. Izi mapindu ake zimadza chifukwa cha mtengo wa mphamvu zochepa, zovuta kwambiri, komanso zokwera mtengo kwambiri.

Moto wamba wopanda pake umakhala ndi maginito okhazikika omwe amazungulira mozungulira zovuta zokhazikika, kuchotsa mavuto omwe amaphatikizidwa ndi kulumikizana komwe kumalumikizana ndi masamba osuntha. Wowongolera zamagetsi amasintha msonkhano wa wolambira wa DC wa DC, womwe umasinthanitsa gawo ndi mphepo kuti isasunge galimoto. Wowongolera amagawana mphamvu yofananira pogwiritsa ntchito bwalo lokhazikika m'malo mongoyerekeza.

Mosaka zopanda matumbo zimapereka zabwino zingapo pamoto woyaka DC, kuphatikizapo Torquo yayitali ku WATT, Kuchulukitsa kwa Drasion, Kuchotsa kukokoloka kwa rashi, kuchotsedwa kwa roiso, kuchotsedwa kwa ma roiszing kuchokera ku
Wort, ndikuchepetsa kwathunthu kwa zosokoneza electromagneti (EMI). Popanda miyala pa rotor, sakakamizidwa ndi magulu a centrifuga, ndipo chifukwa chakuti minda imathandizidwa ndi nyumbazo, zimatha kukhazikika ndi kuphatikizika, osafunikira kuti pakhale mpweya wabwino. Izi zikutanthauza kuti zolengedwa zapamwamba zagalimoto zitha kutsekeredwa kwathunthu ndikutetezedwa ku dothi kapena chinthu chinanso chakunja.

Kutchinga kwamagalimoto sikutha kukhazikitsidwa m'mapulogalamu pogwiritsa ntchito microcortherler, kapena kugwiritsidwa ntchito molakwika pogwiritsa ntchito analog kapena madera a digito. Kuyenderana ndi zamagetsi m'malo mwa mabulosi kumalola kusinthasintha kwakukulu ndi mabotolo owoneka bwino, kuphatikiza kuthamanga kwapang'onopang'ono, komanso kuwongolera kolowera, komanso chiwongola dzanja. Mapulogalamu olamulira amatha kusinthidwa ku galimoto ina yomwe ikugwiritsidwa ntchito pogwiritsa ntchito, zomwe zimapangitsa kuti pakhale kusinthasintha kwabwino.

Mphamvu yayikulu yomwe ingagwiritsidwe ntchito kumoto wopanda pake imangokhala ndi kutentha kokha;

Mukamatembenuza magetsi kukhala mphamvu yopanga, zosinthika zopanda pake ndizothandiza kwambiri kuposa kusanjikiza chifukwa chakusowa kwa maburashi, zomwe zimachepetsa mphamvu zamagetsi, zomwe zimachepetsa mphamvu. Kuchita bwino kwambiri kumayiko ena komanso malo otsika-otsika a mafayilo amoto.

Madera ndi zofunikira momwe opanga amagwiritsira ntchito zotchinga za DC.

Kupanga magalimoto opanda pake kumafanana ndi chovuta, koma motaka kumakhala ndi kusiyana kofunikira chifukwa cha kusiyana komwe pakuyenera kukhazikitsa ndi kugwira ntchito. Ngakhale matomitala ozungulira nthawi zambiri amasiya ndi rotor pamalo ofotokozedweratu, nthawi zambiri mumalinganiza kuti abweretse kusinthasintha kosalekeza. Mitundu yonse yonse yamagalimoto imatha kukhala ndi rotor yolowera inor ya mayankho amkati. Makina onse ojambula ndi chofufumitsa bwino kwambiri amatha kulimbana ndi zotupa pa zero rpm.
