Kev ua haujlwm ntawm Commutator hauv DC Machine

Commutatorhauv DC Motor

CovcommuatorNyob rau hauv cov ntaub ntawv ntawm DC lub cev muaj zog, nws thim rov qab qhov ntws ntawm tam sim no uas nkag tau los ntawm DC qhov chaw raws lub sijhawm thaum lub armatures coil hla qhov sib nqus tsis sib haum. Qhov no yog qhov tseem ceeb los khaws lub zog uni-directional. Yog li ntawd, lubcommuatoryuav hloov cov tam sim no ncaj qha (DC) mus rau hauv alternating tam sim no (AC).
Commutatorhauv DC Generator

CovcommuatorNyob rau hauv cov ntaub ntawv ntawm ib tug DC generator, lub induced emf nyob rau hauv lub armature coil yuav hloov nyob rau hauv cov xwm. Yog li ntawd, qhov ntws ntawm tam sim no nyob rau hauv lub armature coil kuj yuav raug hloov. Qhov tam sim no yuav thim rov qab los ntawm commutator ntawm lub sijhawm tiag tiag thaum lub armatures coil hla qhov sib nqus tsis sib haum. Yog li, lub load uas yog sab nraud rau lub tshuab hluav taws xob yuav tau txais uni-directional tam sim no txwv tsis pub DC (ncaj tam tam sim no).
