Yog li koj tau dawm hla ob lub xov hlau hauv koj lub alternator thiab xav tsis thoob tias lawv yog dab tsi.

Ob-xaim alternators tsis yog siv nyob rau hauv niaj hnub tsheb, raws li peb-los yog plaub-xaim alternators feem ntau ntsia. Yuav kom paub qhov txawv ntawm cov xov hlau no, koj yuav tsum paub koj tus kheej nrog lawv cov duab sib txuas sib txuas, uas peb yuav piav qhia hauv qab no.

Cia peb saib ntxiv...

Tsheb generator txuas daim duab

Saib ntawm lub tshuab hluav taws xob, koj yuav pom tsuas yog ob lub xov hlau: lub zog cable thiab cov xaim excitation. Txawm li cas los xij, lub tshuab hluav taws xob muaj qhov sib txuas ntau dua vim nws txuas ntau qhov sib txawv. Kuv muab daim duab txuas generator hauv qab no. Tam sim no cia saib cov kev sib txuas no:

3-wire alternator thaiv daim duab

Daim duab XNUMX-xaim qhov sib txawv ntawm qhov kev sib txuas no qhia txog kev sib txuas ntawm qhov sib txawv ntawm lub voj voog.

Peb lub xov hlau tseem ceeb uas ua rau hauv Circuit Court yog lub roj teeb zoo cable, qhov hluav taws xob sensor, thiab hluav taws xob hluav taws xob xaim. Kuj tseem muaj kev sib txuas ntawm lub cav thiab cov khoom siv hluav taws xob hluav taws xob. Thaum lub ntsuas hluav taws xob ntsuas hluav taws xob pom, nws txuas lub zog rau lub tshuab hluav taws xob, nws hloov lub zog ntawm lub cav mus rau lub tshuab hluav taws xob.

Cov alternators uas muaj ntau yam no suav nrog cov khoom siv hauv tsev rau kev tswj fais fab.

Lawv tuaj yeem muab thiab kho tam sim no hauv tib lub voj voog, tsis zoo li ib lub xov hlau hloov pauv. Tag nrho cov khoom yuav tau txais kev tswj hwm qhov hluav taws xob yog tias koj siv lub tshuab hluav taws xob peb-xaim.

Sab nraud electromechanical voltage regulator

Lub voltage sensor cable raug mob rau hauv electromagnet los ntawm motorized regulators.

Qhov no tsim ib qho chaw sib nqus nyob ib ncig ntawm cov hlau nplaum, rub cov hlau thaiv hauv nws cov kev taw qhia. Nyob rau hauv xws li ib tug circuits muaj peb electromagnetic keyboards - ib tug mus txawv tebchaws relay, ib tug regulator thiab ib tug tam sim no regulator. Lub converter thiab cov uas twb muaj lawm regulator hloov tswj cov zis voltage los ntawm kev tswj lub excitation Circuit Court ntawm lub alternator, thaum lub disconnect relay txuas lub roj teeb mus rau lub generator.

Txawm li cas los xij, vim qhov tsis muaj txiaj ntsig ntawm kev siv hluav taws xob, hluav taws xob hluav taws xob tsis tshua siv hauv tsheb niaj hnub no, txawm hais tias lawv tseem ceeb heev rau AC txoj cai circuits.

Daim duab kab hluav taws xob tswj los ntawm PCM

Ib qho alternator uas siv cov modules sab hauv los tswj lub excitation Circuit Court yog hu ua powertrain control module voltage regulation circuit.

PCM tswj xyuas qhov ntws ntawm tam sim no los ntawm kev txheeb xyuas cov ntaub ntawv los ntawm lub cev tswj module (BCM) thiab tshuaj xyuas cov kev them nqi ntawm lub cev.

Cov modules tau qhib yog tias qhov hluav taws xob poob qis dua qhov tsim nyog, uas nyob rau lub sijhawm hloov pauv tam sim no ntws los ntawm lub kauj.

Yog li ntawd, nws hloov cov zis ntawm qhov system raws li nws cov kev xav tau. PCR tswj alternators yog qhov yooj yim tab sis ua tau zoo heev hauv kev tsim cov hluav taws xob xav tau.

Lub tshuab hluav taws xob tsheb ua haujlwm li cas?

Kev ua haujlwm ntawm lub tshuab hluav taws xob yog yooj yim to taub.

Lub tshuab hluav taws xob yog fastened nrog V-ribbed siv, muab tso rau ntawm lub pulley. Lub pulley tig thiab tig lub tshuab hluav taws xob rotor shafts thaum lub cav khiav. Lub rotor yog ib qho electromagnet nrog cov txhuam hniav thiab ob lub rotating hlau rings txuas nrog nws ncej. Nws muab cov hluav taws xob me me rau lub rotor raws li cov khoom sib hloov thiab hloov lub zog mus rau stator. (1)

Cov hlau nplaum khiav los ntawm cov hlua tooj liab hauv stator alternator ntawm lub rotor. Yog li ntawd, nws tsim ib qho chaw sib nqus nyob ib ncig ntawm lub coils. Thaum lub magnetic teb raug cuam tshuam raws li lub rotor tig, nws tsim hluav taws xob. (2)

Lub alternator's diode rectifier tau txais AC tab sis yuav tsum tau hloov mus rau DC ua ntej siv. Ob txoj kev tam sim no yog hloov los ntawm lub rectifier rau hauv ib txoj kev ntws ncaj qha tam sim no. Tom qab ntawd lub voltage yog siv rau lub voltage regulator, uas kho qhov voltage raws li qhov yuav tsum tau ntawm ntau yam automotive systems.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
