Cov cav DC siv dav hauv cov qhov rooj tsis siv neeg vim lawv ua haujlwm tau zoo, tsis tas yuav kho, thiab yooj yim tswj qhov ceev. Txawm li cas los xij, muaj ob hom cav DC: brushless thiab brushed. Lawv muaj cov yam ntxwv sib txawv thiab cov txiaj ntsig uas haum rau ntau yam kev siv.
Cov tshuab hluav taws xob DC uas tsis txhuam siv cov hlau nplaum tas mus li ua cov rotors thiab cov hluav taws xob circuits ua cov commutators. Lawv tsis muaj txhuam lossis commutators uas hnav tawm ntawm kev sib txhuam. Yog li ntawd, lawv muaj lub neej ntev dua, suab nrov qis dua, qhov ceev ceev dua, tswj tau torque zoo dua, thiab muaj zog ntau dua li cov tshuab hluav taws xob DC uas txhuam. Lawv kuj muaj kev cuam tshuam electromagnetic qis dua thiab tuaj yeem ua haujlwm tau zoo hauv qhov chaw nyuaj.
Cov brushed DC motors siv cov hlau los yog carbon txhuam thiab cov mechanical commutators los hloov qhov tam sim no. Lawv muaj cov qauv yooj yim dua, pheej yig dua, yooj yim dua rau kev teeb tsa, thiab muaj ntau dua li brushless DC motors. Lawv kuj muaj kev ua haujlwm zoo dua ntawm qhov ceev qis thiab tuaj yeem pib tam sim ntawd yam tsis muaj tus tswj.
Qhov zoo ntawm cov brushless DC motors ua rau lawv haum rau cov qhov rooj tsis siv neeg uas xav tau kev kub ceev, kev raug siab, suab qis, lub neej ntev, thiab kev siv hluav taws xob zoo. Piv txwv li, lawv tuaj yeem siv rau hauv cov qhov rooj swb uas xav tau qhib thiab kaw sai thiab du. Qhov zoo ntawm brushed DC motors ua rau lawv haum rau cov qhov rooj tsis siv neeg uas xav tau tus nqi qis, yooj yim teeb tsa, yooj yim tswj, thiab lub zog pib siab. Piv txwv li, lawv tuaj yeem siv rau hauv cov qhov rooj viav uas xav tau kev kov yeej inertia thiab kev sib txhuam.
