Lub luag haujlwm ntawm cov txhuam hniav hauv cov motors

Cov pa roj carbon txhuam yog siv nruab nrab ntawm qhov chaw nres tsheb thiab tig qhov chaw ntawm lub cev muaj zog, cov tshuab hluav taws xob lossis lwm cov tshuab tig thiab ua ib qho ntawm nws cov khoom tseem ceeb. Raws li kev sib cuag zawv zawg, cov txhuam hniav yog siv dav hauv ntau yam khoom siv hluav taws xob. Cov khoom siv feem ntau yog electrochemical graphite, greased graphite, hlau (xws li tooj liab, nyiaj) graphite. Cov duab yog duab plaub, thiab cov hlau hlau yog ntsia rau lub caij nplooj ntoos hlav. Cov txhuam hniav yog cov zawv zawg sib cuag, yog li nws yooj yim rau hnav thiab yuav tsum tau hloov thiab ntxuav tsis tu ncua.

Lub luag haujlwm ntawm cov txhuam hniav yog ua kom paub cov rotor tam sim no uas yuav tsum tau ua los ntawm kev ua haujlwm ntawm lub cev muaj zog rau hauv lub rotor kauj los ntawm cov khoom sib txuas ntawm lub nplhaib. Qhov haum thiab smoothness ntawm cov pa roj carbon txhuam thiab cov khoom sib txuas, thiab qhov loj ntawm qhov chaw sib cuag cuam tshuam rau nws lub neej thiab kev ntseeg tau. Hauv DC lub cev muaj zog, nws tseem ua haujlwm ntawm kev sib hloov (rectifying) lub zog hloov hluav taws xob uas tau tshwm sim hauv armature winding.

Cov commutator yog tsim los ntawm cov txhuam hniav thiab cov nplhaib sib txuas, thiab cov txhuam hniav yog ib hom txhuam hniav. Vim yog kev sib hloov ntawm lub rotor, cov txhuam hniav yeej ib txwm rubbed nrog lub nplhaib sib hloov, thiab qhov hluav taws xob yaig yuav tshwm sim thaum lub sijhawm sib hloov, yog li cov txhuam hniav yog qhov hnav hauv DC lub cev muaj zog.
