Tsis muaj qhov sib txawv ntawm cov txhuam hniav DC lub cev muaj zog thiab txhuam DC lub cev muaj zog hauv cov ntsiab lus, raws li cov txhuam hniav siv hauvDC motorsfeem ntau yog cov txhuam hniav carbon. Txawm li cas los xij, rau qhov pom tseeb hauv qee qhov ntsiab lus, ob qho yuav raug hais thiab piv nrog lwm hom motors. Cov hauv qab no yog cov lus piav qhia ntxaws:

Txhuam DC Tsav

• Txoj Cai Ua Haujlwm: Lub brushed DC lub cev muaj zog ua haujlwm ntawm cov qauv ntawm electromagnetic induction thiab Ampere txoj cai 6. Nws muaj cov khoom xws li stator, rotor, txhuam, thiab commutator. Thaum DC lub zog hluav taws xob muab lub zog rau lub cev muaj zog los ntawm cov txhuam hniav, lub stator tsim cov hlau nplaum zoo li qub, thiab lub rotor, txuas nrog lub zog hluav taws xob los ntawm cov txhuam hniav thiab cov commutator, tsim cov hlau nplaum sib nqus. Kev sib cuam tshuam ntawm rotating magnetic teb thiab stator teb ua electromagnetic torque, uas tsav lub cev muaj zog tig. Thaum lub sijhawm ua haujlwm, cov txhuam txhuam zawv zawg ntawm lub commutator kom thim rov qab tam sim no thiab tswj lub cev muaj zog tsis tu ncua 6.
• Cov yam ntxwv ntawm tus yam ntxwv: Nws muaj cov qauv yooj yim, feem ntau suav nrog stator, rotor, txhuam, thiab commutator. Lub stator feem ntau yog ua los ntawm laminated silicon steel ntawv nrog windings qhov txhab nyob ib ncig ntawm lawv. Lub rotor muaj ib tug hlau core thiab windings, thiab cov windings txuas nrog lub hwj chim mov los ntawm txhuam 6.
• Qhov zoo: Nws muaj qhov zoo ntawm cov qauv yooj yim thiab tus nqi qis, ua kom yooj yim rau kev tsim thiab tswj. Nws kuj muaj qhov pib ua haujlwm tau zoo thiab tuaj yeem muab qhov pib loj torque6.
• Disadvantages: Cov kev sib txhuam thiab sparking ntawm cov txhuam hniav thiab cov commutator thaum ua hauj lwm ua rau hnav thiab tsim kua muag, txo lub cev muaj zog efficiency thiab lifespan. Ntxiv mus, nws cov kev tswj ceev kev ua tau zoo yog qhov tsis zoo, ua rau nws nyuaj rau kev ua tiav kev tswj ceev ceev 6.

Carbon Txhuam DC Tsav

• Txoj Cai Ua Haujlwm: Cov pa roj carbon txhuam DC lub cev muaj zog yog qhov tseem ceeb ntawm DC lub cev muaj zog, thiab nws txoj haujlwm ua haujlwm yog tib yam li cov brushed DC lub cev muaj zog tau piav qhia saum toj no. Cov pa roj carbon txhuam yog nyob rau hauv kev sib cuag nrog lub commutator, thiab raws li lub commutator rotates, cov pa roj carbon txhuam tsis tu ncua hloov cov kev taw qhia ntawm tam sim no nyob rau hauv lub rotor coil los xyuas kom meej lub nruam kev sib hloov ntawm lub rotor.
• Cov yam ntxwv ntawm tus yam ntxwv: Cov qauv yog qhov zoo ib yam li ntawm cov dav hlau txhuam DC lub cev muaj zog, suav nrog stator, rotor, carbon txhuam, thiab commutator. Cov txhuam hniav feem ntau yog ua los ntawm graphite los yog sib xyaw ntawm graphite thiab hlau hmoov, uas muaj cov khoom siv hluav taws xob zoo thiab nws tus kheej lubricating zog, txo qhov hnav thiab tsim kua muag ntawm tus txhuam hniav thiab cov commutator rau qee yam.
• Qhov zoo: Cov txhuam hniav carbon muaj qhov zoo ntawm tus kheej lubricating thiab hnav-tiv taus, uas tuaj yeem txo qhov zaus ntawm kev hloov txhuam thiab cov nqi kho. Nws kuj muaj cov khoom siv hluav taws xob zoo thiab tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm lub cev muaj zog.
• Qhov tsis zoo: Txawm hais tias cov txhuam hniav muaj qhov hnav zoo dua li qee cov txhuam hniav, nws tseem yuav tsum tau hloov tsis tu ncua. Tsis tas li ntawd, kev siv cov pa roj carbon txhuam hniav kuj tseem tuaj yeem tsim qee cov pa roj carbon monoxide, uas yuav tsum tau ntxuav tsis tu ncua kom tsis txhob cuam tshuam rau kev ua haujlwm ntawm lub cev muaj zog.
