Cov qauv ntawm DC lub cev muaj zog muaj ob ntu: stator thiab rotor. Lub luag haujlwm tseem ceeb ntawm stator yog tsim kom muaj qhov sib nqus; lub rotor, tseem hu ua armature, yog siv los tsim electromagnetic torque thiab induced electromotive quab yuam. Qhov sib txawv ntawm stator thiab rotor yog hu ua qhov sib txawv ntawm huab cua. Ncej Cov txheej casing ntawm stator ib feem ntawm lub cev muaj zog yog tus ncej. Nws ua raws li kev txhawb nqa ruaj khov, vim tias nws kuj yog ib feem ntawm kev sib nqus hluav taws xob, thiaj li ua rau txoj kev hla ntawm cov ncej hlau nplaum. (feem ntau yog ua los ntawm steel castings los yog welded steel daim hlau.)
. Lub ntsiab magnetic ncej Lub ntsiab magnetic ncej muaj lub ntsiab sib nqus ncej hlau core thiab excitation winding. Lub luag haujlwm yog tsim kom muaj huab cua sib nqus magnetic teb. (Cov tub ntxhais hlau feem ntau yog ua los ntawm 0.5 ~ 1.5mm tuab steel phaj xuas nrig ntaus riveted.) txhuam cov cuab yeej txhuam hniav yog tsim los ntawm txhuam txhuam, txhuam txhuam, txhuam txhuam thiab txhuam txhuam txhuam. Lub cev muaj zog yog siv los qhia DC voltage lossis DC tam sim no; lub tshuab hluav taws xob yog siv los qhia DC voltage lossis DC tam sim no. Commutation pole Lub me me sib nqus ncej nruab nrab ntawm ob lub ntsiab sib nqus ncej yog hu ua commutation ncej, kuj hu ua ib tug ntxiv ncej. Lub luag haujlwm yog txhawm rau txhim kho kev sib hloov thiab tshem tawm qhov tshwm sim ntawm cov txhuam hniav thiab cov commutator thaum lub cev muaj zog khiav.
Cov ncej feem ntau yog ua los ntawm cov hlau puag ncig. Muab kev txhawb nqa rau rotor kev sib hloov.
armature tub ntxhais.
Cov tub ntxhais armature yog qhov tseem ceeb ntawm txoj kev sib nqus tseem ceeb, uas yog siv los kos lub armature winding. (Feem ntau, nws yog superimposed nrog 0.5mm tuab silicon steel los xij)
Armature winding Lub armature winding yog qhov tseem ceeb ntawm lub zog hloov pauv ntawm DC lub cev muaj zog, thiab nws txoj haujlwm yog los tsim hluav taws xob torque thiab induced electromotive quab yuam.
Lub commutator yog slidably txuas nrog txhuam. Nyob rau hauv DC lub cev muaj zog, lub commutator yog nruab nrog txhuam, uas tuaj yeem hloov cov ntaub ntawv DC tam sim no rau hauv AC tam sim no hauv armature coil, kom cov kev taw qhia ntawm electromagnetic torque yog tas li; nyob rau hauv DC generator, lub commutator yog nruab nrog hluav taws xob tam sim no. Cov txhuam hniav tuaj yeem hloov pauv qhov hloov hluav taws xob hluav taws xob uas cuam tshuam rau hauv armature coil mus rau qhov ncaj qha tam sim no electromotive quab yuam los ntawm cov txhuam zoo thiab tsis zoo.
