Thaum xaiv thiab tsim ib lub tsevtwj tso kua dej me me, lub cev muaj zog tsav yog qhov tseem ceeb rau kev txiav txim siab qhov ua tau zoo, lub neej ua haujlwm thiab tus nqi ntawm lub twj tso kua mis. Feem ntau, ob sab ntawm qhov kev sib tw no yog ib txwm muajcov cav txhuam carbonthiabcov tshuab hluav taws xob niaj hnubKawm txog qhov sib txawv yog qhov tseem ceeb rau kev xaiv lub twj tso kua mis zoo tshaj plaws rau koj qhov project.

Ua ntej, cia kuv piav qhia txog lub tswv yim

Qhov peb feem ntau hu ua "carbon brush motor" thiab "brush motor" hauv thaj chaw ntawm cov twj tso kua dej me me yog hais txog tib hom motor - DC brush motor, uas siv cov carbon brush (brush) los tiv tauj lub commutator los coj cov tam sim no thiab hloov qhov kev taw qhia ntawm lub magnetic field.
Thiab nws cov neeg sib tw, nws yog los ntawm kev sib hloov pauv hluav taws xob ntawmtsis muaj txhuam dc lub cev muaj zogkev tswj hwm.

Yuav kom nkag siab zoo dua txog lawv qhov sib txawv tseem ceeb, peb tuaj yeem ua qhov sib piv sai los ntawm kev saib cov lus hauv qab no:

1. Lub cev muaj zog txhuam carbon: ib qho kev xaiv zoo thiab pheej yig

 

Cov cav txhuam carbon, tseem hu ua brushed DC motors, yog cov kev daws teeb meem tsav tsheb uas paub tab heev.

Txoj Cai Ua Haujlwm
Lub hauv paus yog los ntawm obcov txhuam carbon(ua los ntawm graphite thiab hlau) ua cov khoom sib txuas ruaj khov, nrog rau kev sib hloovdaim ntawv commutatorntawm lub cev muaj zog rotor txuas ntxiv mus, yog li ntawd qhov kev taw qhia tam sim no hloov tas li, yog li ntawd lub rotor txuas ntxiv tig.

Cov Nta Tseem Ceeb:

1 Qhov Zoo:

Tus Nqi Qis: Cov qauv yooj yim, cov thev naus laus zis paub tab, tus nqi tsim khoom qis dua li lub cev muaj zog brushless, uas ua rau tag nrho cov twj tso kua mis tus nqi sib tw heev.

 

Kev Tswj Yooj Yim：Qhov ceev thiab torque tuaj yeem hloov kho tau yooj yim los ntawm kev hloov qhov voltage lossis tam sim no, xws li siv kev tswj ceev PWM yooj yim, tsis tas yuav muaj cov voj voog tsav nyuaj.

2.Qhov tsis zooLub neej luv: Qhov no yog qhov tsis zoo tshaj plaws ntawm lub cev muaj zog txhuam carbon. Lub txhuam carbon yog siv tau thiab yuav maj mam hnav tawm thaum lub sijhawm ntev sib txhuam nrog lub commutator. Thaum hnav tawm, lub cev muaj zog yuav ua tsis tiav. Yog li ntawd, lub neej ntawm cov tshuab txhuam carbon feem ntau yog txij li ntau pua txog ntau txhiab teev

3. Kev cuam tshuam electromagnetic yuav raug tsim tawm:Cov txhuam carbon thiab lub commutator yuav tsim cov hluav taws xob thaum lub sijhawm sib cuag thiab sib cais, uas yuav ua rau muaj kev cuam tshuam electromagnetic rau cov khoom siv hluav taws xob nyob ib puag ncig.

4.Kev ua haujlwm tsis zoo:vim yog qhov tsis kam ntawm kev sib txhuam thiab kev sib cuag ntawm cov txhuam carbon, qhov poob zog loj heev, thiab qhov ua tau zoo feem ntau qis dua li ntawm cov tshuab brushless.

5. Nrov nrov:kev sib txhuam ntawm cov txhuam carbon thiab lub hluav taws xob yuav tsim qee lub suab nrov ua haujlwm.

2-Lub cev muaj zog tsis txhuam: kev xaiv niaj hnub ntawm kev ua tau zoo siab

Lub cev muaj zog tsis txhuamsawv cev rau kev coj ua thev naus laus zis zoo dua thiab ua haujlwm tau zoo dua.

Txoj Cai Ua Haujlwm：
Nws tshem tawm qhov kev sib cuag ntawm lub txhuam carbon thiab lub commutator. Hloov chaw, ib qhotus tswj hwm hluav taws xobsiv los ntsuas qhov chaw ntawm lub rotor thiab tswj qhov kev sib lawv liag ntawm lub zog thiab lub sijhawm ntawm cov stator coils kom meej, yog li ntawd tsav lub rotor kom tig. Qhov no yog "electronic" es tsis yog "mechanical" reversal.

Qhov Tseem Ceeb：

Cov txiaj ntsig：

Lub neej ntev：Vim tias tsis muaj qhov sib chwv uas yuav tsum tau hnav, nws lub neej tsuas yog nyob ntawm qhov hnav ntawm cov kabmob, feem ntau txog li kaum tawm txhiab teev, uas yog kaum lossis txawm tias kaum npaug ntawm lub neej ntawm lub cev muaj zog txhuam carbon.

Kev ua haujlwm zoo, kev siv hluav taws xob tsawg：Tsis muaj kev poob ntawm kev sib cuag thiab qhov ua tau zoo ntawm kev hloov pauv hluav taws xob yog siab, uas txhais tau tias nws txuag hluav taws xob ntau dua lossis tuaj yeem muab cov zis ntau dua ntawm tib lub zog.

Lub suab qis：Tsis muaj suab nrov txhuam carbon, kom khiav ntsiag to dua.

Tsis muaj kev cuam tshuam hluav taws xob:Tsis muaj teeb meem EDM, zoo heev rau cov tshuab hluav taws xob rhiab heev.

Kev tswj tau siab:Thaum ua ke nrog lub maub los ntse, nws tuaj yeem ua tiav cov haujlwm siab heev xws li kev tswj qhov ceev kom raug, kev tiv thaiv rotor xauv, thiab cov teeb liab tawm tswv yim.

Qhov Tsis Zoo:

Tus nqi siab:Cov qauv ntawm lub cev muaj zog thiab cov tswj hwm tsav uas xav tau yog qhov nyuaj dua li cov ntawm cov pa roj carbon txhuam lub cev muaj zog, ua rau tus nqi tag nrho siab dua3.

Kev tswj hwm nyuaj:Nws yuav tsum vam khom lub tshuab tswj hwm tshwj xeeb kom ua haujlwm thiab tsis tuaj yeem tig ncaj qha thaum muaj zog zoo li lub cav txhuam carbon.
