Nyob rau hauv lub realm ntawm hluav taws xob engineering, direct tam sim no (DC) motors ua si ib tug tseem ceeb luag hauj lwm nyob rau hauv ib tug dav array ntawm daim ntawv thov. Ntawm cov DC motors, cov uas muaj cov txhuam hniav feem ntau siv. Txawm li cas los xij, zoo li muaj qee qhov tsis meej pem txog carbon txhuam DC motors thiab txhuam DC motors. Hauv tsab xov xwm no, peb yuav txheeb xyuas qhov sib txawv ntawm lawv thiab tshawb xyuas lawv cov xwm txheej ntawm daim ntawv thov.
Clarifying lub Terminology
Ua ntej, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov roj carbon txhuam DC motors yog qhov ua tau zoo ntawm cov txhuam DC motors. Lub sij hawm " txhuam DC lub cev muaj zog" yog ib qho kev faib tawm ntau dua, thaum "carbon txhuam DC lub cev muaj zog" tshwj xeeb yog hais txog txhuam DC lub cev muaj zog uas cov txhuam hniav yog tsim los ntawm cov khoom siv carbon feem ntau.
Cov qauv thiab cov khoom sib txawv
Txhuam Khoom
- Carbon Txhuam DC Motors: Raws li lub npe implies, txhuam hauv cov motors no feem ntau yog ua los ntawm carbon. Cov pa roj carbon monoxide muaj qhov zoo ntawm nws tus kheej lubricating zog, uas txo cov kev sib txhuam ntawm cov txhuam thiab cov commutator. Qhov no ua rau tsis muaj kev hnav thiab tsim kua muag, ua rau lub neej ntev ntawm cov txhuam hniav. Tsis tas li ntawd, carbon yog cov khoom siv hluav taws xob zoo, txawm hais tias nws cov conductivity tsis siab npaum li qee cov hlau. Piv txwv li, nyob rau hauv me me - scale hobbyist motors, carbon txhuam feem ntau siv vim lawv cov nqi - kev ua tau zoo thiab kev ntseeg tau.
- Txhuam DC Motors (hauv kev nkag siab dav): Txhuam hauv cov tsis- carbon - txhuam DC motors tuaj yeem ua los ntawm ntau yam ntaub ntawv. Hlau - graphite txhuam, piv txwv li, muab cov hluav taws xob hluav taws xob siab ntawm cov hlau (xws li tooj liab) nrog rau nws tus kheej - lubricating thiab hnav - resistant zog ntawm graphite. Cov txhuam hniav no feem ntau yog siv rau hauv cov ntawv thov uas muaj zog dua tam sim no - yuav tsum muaj peev xwm nqa tau.
Commutator Kev sib tham
- Carbon Txhuam DC Motors: Cov txhuam txhuam cov pa roj carbon txhuam tau yooj yim hla ntawm qhov chaw commutator. Kev sib txuas ntawm tus kheej ntawm cov pa roj carbon monoxide pab tswj lub zog sib txuas, uas yog qhov tseem ceeb rau kev ruaj ntseg hluav taws xob sib txuas. Qee zaum, cov txhuam hniav carbon kuj tseem tuaj yeem tsim hluav taws xob tsawg dua thaum lub sijhawm ua haujlwm, ua rau lawv tsim nyog rau cov ntawv thov kev cuam tshuam rau electromagnetic cuam tshuam.
- Txhuam DC Tsav nrog Txhuam Txhuam: Hlau - graphite txhuam, vim lawv cov khoom sib txawv ntawm lub cev, yuav xav tau tus qauv sib txawv ntawm cov commutator. Kev ua tau zoo dua ntawm cov hlau feem yuav ua rau muaj qhov sib txawv tam sim no - cov qauv kev faib tawm ntawm qhov chaw commutator, thiab yog li, lub commutator yuav tsum tau tsim los tswj qhov no zoo dua.
Kev ua tau zoo sib txawv
Fais fab thiab Efficiency
- Carbon Txhuam DC Motors: Feem ntau, cov pa roj carbon txhuam DC lub cev muaj zog zoo - haum rau cov ntawv siv hluav taws xob tsawg-rau- nruab nrab. Lawv cov conductivity qis dua piv rau qee cov hlau - raws li cov txhuam hniav yuav ua rau muaj hluav taws xob ntau dua me ntsis, uas tuaj yeem ua rau qee lub zog poob rau hauv daim ntawv ntawm tshav kub. Txawm li cas los xij, lawv tus kheej lubricating cov cuab yeej txo cov neeg siv khoom poob vim kev sib txhuam, uas pab tswj kom muaj txiaj ntsig zoo tag nrho. Piv txwv li, hauv cov khoom siv hauv tsev me me xws li cov kiv cua hluav taws xob, cov pa roj carbon txhuam DC motors feem ntau siv, muab lub zog txaus thaum lub zog tseem tshuav - muaj txiaj ntsig txaus rau kev siv hauv tsev.
- Txhuam DC Tsav nrog Txhuam Txhuam: Lub cev muaj zog nrog hlau - graphite txhuam feem ntau siv rau hauv kev siv hluav taws xob siab. Lub siab hluav taws xob conductivity ntawm cov hlau tivthaiv tso cai rau kev hloov pauv ntawm qhov loj ntawm tam sim no, ua rau muaj zog ntau dua. Muaj cov tshuab, xws li cov tshuab loj loj, feem ntau siv cov motors no los tsav cov khoom hnyav.
Tswj ceev
- Carbon Txhuam DC Motors: Kev tswj ceev ntawm cov pa roj carbon txhuam DC motors tuaj yeem ua tiav los ntawm ntau txoj hauv kev, xws li kho qhov hluav taws xob input voltage. Txawm li cas los xij, vim lawv cov yam ntxwv ntawm tus kheej, lawv yuav tsis muab tib theem ntawm kev tswj ceev ceev ib yam li lwm hom motors. Hauv cov ntawv thov uas qhov kev ruaj ntseg ceev tsis yog qhov tseem ceeb tshaj plaws, zoo li hauv qee qhov yooj yim qhov cua kiv cua, carbon txhuam DC motors tuaj yeem ua tau zoo.
- Txhuam DC Tsav nrog Txhuam Txhuam: Qee qhov xwm txheej, tshwj xeeb tshaj yog nrog cov khoom siv txhuam thiab cov qauv tsim ntau dua, kev tswj kom nrawm dua tuaj yeem ua tiav. Lub peev xwm los tswj cov dej ntws siab dua thiab kev sib txuas hluav taws xob ruaj khov tuaj yeem ua kom muaj kev sib tw nrawm dua - tswj cov txheej txheem, xws li siv mem tes - dav hloov kho (PWM) zoo dua. Kev ua haujlwm siab servo motors, uas yuav tsum tau tswj ceev ceev rau cov ntawv thov xws li cov neeg hlau, tuaj yeem siv txhuam nrog cov khoom tshwj xeeb rau lub hom phiaj no.
