Kev kub hnyiab los ntawm kev txhuam yog ib qho teeb meem tshwm sim hauv kev ua haujlwm ntawm DC motors lossis wound rotor asynchronous motors. Cov hluav taws xob tsis yog tsuas yog ua kom cov txhuam thiab commutators / slip rings hnav sai dua, tab sis kuj tsim kev cuam tshuam electromagnetic thiab tej zaum yuav ua rau muaj kev phom sij rau kev nyab xeeb. Morteng tshuaj xyuas cov laj thawj ntawm qhov teeb meem los ntawm cov hauv qab no:
Kev Ua Tau Zoo: Cov txhuam hnav sai thiab hloov pauv ntau zaus; pom tseeb cov hluav taws xob thaum lub sijhawm ua haujlwm, txawm tias hlawv qhov chaw ntawm lub nplhaib plam; txhuam dhia lossis co.
Cov ua rau lub tshuab hluav taws xob tseem ceeb:
Kev sib txhuam tsis zoo: Qhov no yog ib qho ntawm cov laj thawj feem ntau.
Lub zog ntawm lub caij nplooj ntoos hlav tsis txaus: Lub caij nplooj ntoos hlav laus zuj zus, hloov pauv, lossis qhov chaw teeb tsa lub zog pib qis dhau tuaj yeem ua rau lub zog sib cuag tsis txaus ntawm txhuam thiab lub commutator/slip ring, ua rau muaj kev tiv thaiv kev sib cuag ntau ntxiv, ua rau cov ntsiab lus sib cuag kub zuj zus, thiab ua rau muaj hluav taws xob ntau dua thaum lub sijhawm hloov pauv tam sim no lossis micro-vibrations.
Lub caij nplooj ntoos hlav siab dhau: Txawm hais tias lub siab dhau yuav ua rau kev sib cuag zoo dua, nws ua rau kev sib txhuam thiab kev hnav ntau ntxiv, tsim kom muaj cua sov thiab hmoov av carbon ntau dhau, thiab yuav ua rau cov zaj duab xis oxide ntawm qhov chaw commutator puas tsuaj, yog li ua rau muaj hluav taws xob ntau ntxiv.
Cov txhuam uas daig rau hauv lub thawv txhuam: Kev puas tsuaj ntawm lub thawv txhuam, kev sib sau ua ke ntawm cov av, qhov loj ntawm txhuam tsis sib xws, lossis kev hnav ntawm ob sab ntawm cov txhuam tuaj yeem ua rau lawv txav mus tsis tau yooj yim hauv lub thawv txhuam, tiv thaiv lawv kom tsis txhob ua raws li qhov kev co me me lossis qhov sib txawv ntawm cov commutator / slip rings, ua rau muaj kev sib cuag tsis ruaj khov.
Qhov tsis zoo ntawm qhov chaw ntawm lub commutator/slip ring: Qhov tsis sib xws ntawm qhov chaw (kos, qhov, cov cim hlawv), ellipticity/eccentricity ntau dhau, cov ntawv mica tawm (commutator), lossis kev txav axial ntau dhau tuaj yeem cuam tshuam qhov kev sib txhuam du thiab txuas ntxiv ntawm txhuam thiab qhov chaw tig.
Kev teeb tsa txhuam tsis raug: Cov txhuam tsis tau teeb tsa kom raug ntawm qhov chaw nruab nrab lossis ntawm lub kaum sab xis.
Kev co ntawm lub tshuab ntau dhau: Kev co ntawm lub cev muaj zog lossis cov khoom siv tsav tsheb raug xa mus rau thaj chaw txhuam, ua rau txhuam txav mus los.
Kev hnav tsis sib xws ntawm lub commutator / slip ring: Ua rau muaj qhov chaw tsis sib xws.
