DC tshuab feem ntau yog cais nyob rau hauv lub hauv paus ntawm lawv teb kev zoo siab txoj kev. Qhov no ua rau ob pawg dav dav dc cov cav tov ; (i) Sib cais zoo siab thiab (ii) Tus kheej zoo siab. Nyob rau hauv ib tug self-excited hom DC lub tshuab hluav taws xob , teb winding yog energized los ntawm tam sim no ua los ntawm lawv tus kheej.

Raws li txoj cai, kev faib tawm ntawm DC tshuab yog dab tsi?

Muaj ob hom ntawm excitation hauv D. Cmachine . cais excitation, thiab self-excitation.

Lub hom phiaj tseem ceeb ntawm DC tshuab yog:

  • cais zoo siab d.c. tshuab.
  • Shunt qhov txhab los yog shunt tshuab.
  • Series mob los yog series tshuab.
  • Compound lub qhov txhab los yog compound tshuab.

Ib sab saum toj no, muaj pes tsawg hom DC tshuab muaj thiab lawv faib li cas? Cov DC tshuab tuaj yeem yog cais ua ob hom uas yog DC motors zoo li DC cov tshuab hluav taws xob. Feem ntau ntawm DC tshuab yog sib npaug rau AC tshuab vim lawv suav nrog AC dej ntws zoo li qub AC voltages hauv lawv. Cov zis ntawm lub DCmachine yog DC output vim lawv hloov AC voltage rau DC hluav taws xob.

Ib sab ntawm qhov no, txhais li cas los ntawm excitation hauv DC tshuab?

Kev zoo siab yog cov txheej txheem ntawd txuam nrog thefield system, wherein dc ua Tam sim no ntws los ntawm winding inpoles tsim magnetic polarity. Kev sib txuas hluav taws xob ntawm lub teb winding mus rau armature winding cia peb faib dcmotors.

Lub tshuab hluav taws xob DC sib cais ua haujlwm li cas?

Hauv ib cais zoo siab (S. E.) tshuab, fieldwinding txuas nrog a cais voltage qhov chaw thaum, nyob rau hauv tus kheej zoo siab generator teb winding yog txuas nrog hla lub armature terminals (muab nws zoo siab tam sim no).
