Kev tswj ceev ceev thiab kev tswj xyuas siab: Qhov ceev ntawm DC lub cev muaj zog yog linearly cuam tshuam nrog lub armature voltage, tso cai rau kev sib tw, stepless ceev tswj los ntawm kev kho qhov voltage lossis armature kuj.
Siab pib torque thiab muaj zog tshaj lub peev xwm: DC motors tuaj yeem tso tawm 2-3 npaug ntawm lawv qhov ntsuas torque thaum pib.
Cov qauv yooj yim thiab tus nqi txij nkawm qis: Cov qauv tseem ceeb ntawm lub cev muaj zog DC suav nrog stator (magnetic tsis tu ncua lossis electromagnet), rotor (armature winding), commutator, thiab txhuam. Nws cov qauv siv tshuab yog qhov yooj yim, nrog rau qhov tsawg thiab qhov tsis ua haujlwm tsawg.
Kev ua haujlwm siab thiab kev siv hluav taws xob tsawg: DC motors feem ntau ua tiav 85% -95% kev ua haujlwm, nrog rau kev ua haujlwm tau zoo dua nyob rau hauv qis - ceev, siab-torque.
Kev siv ntau yam thiab muaj zog yoog raws: Vim nws qhov zoo hauv kev tswj ceev, pib- nres, thiab ua haujlwm tau zoo, DC motors tau siv dav hauv cov xwm txheej uas xav tau kev tswj xyuas meej.
Lub peev xwm tseem ceeb rau kev hloov kho thev naus laus zis: Nrog rau kev txhim kho cov khoom siv hlau nplaum ruaj khov (xws li neodymium hlau boron) thiab cov tshuab hluav taws xob hluav taws xob, kev ua haujlwm ntawm DC motors tau txhim kho ntxiv.
