DC kev taw qhia
Ib qho DC motor yog lub tshuab hluav taws xob uas hloov ua hluav taws xob uas siv DC lub zog hluav taws xob rau lub tshuab hluav taws xob (DC motor) los yog hloov tshuab hluav taws xob mus rau DC lub zog hluav taws xob (DC generator). Nws yog ib lub cav uas ua rau hloov DC zog thiab txhua yam muaj zog. Thaum nws siv los ua lub cav, nws yog DC tsav uas hloov cov hluav taws xob ua hluav taws xob rau hauv tshuab hluav taws xob. Thaum lub tshuab hluav taws xob khiav, nws yog ib qho hluav taws xob DC uas hloov cov tshuab hluav taws xob rau hauv hluav taws xob. Txoj haujlwm ua haujlwm ntawm DC generator yog hloov qhov kev siv zog ntawm lwm lub tshuab hluav taws xob los ntawm kev sib tsoo ntawm kev sib dhos thiab kev txhuam kom hloov DC lub zog tawm hauv lub tshuab hluav taws xob thaum nws raug rho tawm ntawm txhuam qhov kawg.

Cov qauv ntawm DC lub tsheb yuav tsum muaj ob ntu: stator thiab rotor. Ib feem ntawm DC lub cev uas nyob ruaj ruaj thaum ua haujlwm yog hu ua stator. Lub ntsiab tseem ceeb ntawm tus stator yog los ua kom tau ib lub teb chaw magnetic. Nws muaj ib lub hauv paus, ib qho tseem ceeb, ib tug ncej, ib qho kawg ntawm lub hau, ib tug kabmob thiab ib tug txhuam khoom. Qhov uas tig rov qab thaum lub sijhawm ua haujlwm yog hu ua rotor. Nws lub ntsiab muaj nuj nqi yog los ua kom muaj zog ntawm electromagnetic torque thiab vim raug yuam kom siv zog. Nws yog qhov piv txwv ntawm lub zog hloov ntawm DC tsav, yog li nws yog feem ntau hu ua armature. Nws hloov los ntawm lub taub hau, tub ntxhais hlua khau, tshuab raj winding, thiab nws muaj ib qho kev sib txuas lus thiab kiv cua.
