Hnub no, kev lag luam feem ntau siv cov zaus hloov pauv rau asynchronous motors. Nws yog ib nqi sau cia hais tias xws motors muaj peb windings nyob rau hauv lawv tsim, uas yog kev cob cog rua raws li "lub hnub qub" los yog "daim duab peb sab" tswvyim. Tab sis lawv muaj ib tug drawback - nws yog ib qho nyuaj heev los tswj qhov ceev ntawm kev sib hloov ntawm lub rotor. Tab sis nws zoo li ua ntej. Tam sim no, thaum micro- thiab lub zog hluav taws xob hluav taws xob tuaj yeem cawm, txoj haujlwm no yooj yim dua. Los ntawm kev tig qhov sib txawv ntawm cov resistor, koj tuaj yeem hloov qhov kev sib hloov ceev hauv ntau yam.
Koj xav tau lub tshuab hloov pauv li cas?
Cov cuab yeej no muaj ntau txoj haujlwm, tab sis feem ntau siv me me. Nyob rau hauv qhov tseeb, los tswj lub asynchronous lub cev muaj zog, koj yuav tsum tau kho tsis tau tsuas yog cov kev sib hloov ceev, tab sis kuj lub acceleration thiab deceleration lub sij hawm. Tsis tas li ntawd, txhua qhov system xav tau kev tiv thaiv. Nws yog qhov tsim nyog tiastus zaus converter coj mus rau hauv tus account qhov tam sim no noj los ntawm lub asynchronous lub cev muaj zog.
Chastotniki tau siv dav hauv cov tshuab ua pa. Txawm hais tias lub teeb pom kev ntawm lub kiv cua impeller, cov loads ntawm lub rotor yog loj heev. Thiab instant overclocking yog tsis yooj yim sua. Kuj tseem muaj cov xwm txheej uas yuav tsum tau ua kom qhov kev sib hloov ceev kom cov huab cua ntws ntau dua los yog tsawg dua. Tab sis qhov no tsuas yog ib qho piv txwv xwb, lub zaus converter feem ntau siv nyob rau hauv lwm lub tshuab. Nrog kev pab los ntawm ib tug zaus converter, koj muaj peev xwm synchronize lub ceev ntawm ib tug conveyor muaj ob peb tapes.
Txoj cai ua haujlwm ntawm zaus hloov pauv
Nws yog raws li kev tswj hwm microprocessor thiab ntau lub voj voog rau kev hloov AC thiab DC voltages. Ob peb txheej txheem tshwm sim nrog qhov voltage uas yog siv rau lub hwj chim input ntawm lub cuab yeej. Kev ua haujlwm ntawm qhov hloov pauv zaus yog qhov yooj yim, nws txaus los xav txog peb theem. Ua ntej, muaj kev sib tw. Thib ob, lim. Thirdly, inverting yog hloov dua siab tshiab tam sim no mus rau alternating tam sim no.
Tsuas yog nyob rau theem kawg nws tuaj yeem hloov pauv cov khoom thiab qhov ntsuas tam sim no. Los ntawm kev hloov cov yam ntxwv ntawm tam sim no, nws muaj peev xwm tswj tau qhov ceev ntawm kev sib hloov ntawm lub rotor ntawm lub asynchronous lub cev muaj zog. Hwj chim sib dhos ntawm transistors yog siv nyob rau hauv lub inverter theem. Cov ntsiab lus no muaj peb qhov tso tawm - ob lub zog, thiab ib qho kev tswj hwm. Cov yam ntxwv tam sim no-voltage ntawm qhov tso zis ntawm lub zaus hloov pauv nyob ntawm qhov loj ntawm lub teeb liab siv rau tom kawg.
Yuav ua li cas hloov lub inverter?
zaus converters rau asynchronous motors pib siv tsis ntev los no. Tab sis kev tshawb fawb tau mus rau lawv maj mam, thaum xub thawj qhov ceev ntawm kev sib hloov ntawm lub rotor tau hloov pauv siv lub zog lossis lub variator. Muaj tseeb, xws li kev tswj tau cumbersome heev, thiab lub zog tsav tau nkim vim tsis tsim nyog mechanisms. Txoj siv sia siv tau pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, nws tau pab txhawb txoj kev sib hloov ceev, nws tau dhau los ua qhov nyuaj heev) txhawm rau txhawm rau ntsuas qhov ntsuas kawg. Rau cov laj thawj no, nws muaj txiaj ntsig ntau dua los siv lub tshuab hloov pauv zaus, vim nws tsis txhob poob hluav taws xob. Tab sis qhov tseem ceeb tshaj plaws, nws ua rau nws muaj peev xwm hloov cov tsav tsheb yam tsis tau hloov pauv rau cov tshuab.
Yuav ua li cas xaiv rau tsev siv?
Nws tsim nyog sau cia tias kev sib txuas tuaj yeem ua rau ib leeg- thiab peb-theem tam sim no. Nws tag nrho yog nyob ntawm tus qauv tshwj xeeb ntawm lub inverter, thiab tshwj xeeb tshaj yog, ntawm qhov twg Circuit Court ntawm zaus converter ntawm lub asynchronous lub cev muaj zog tau siv nyob rau hauv ntau lawm. Txhawm rau kom nkag siab lub hauv paus ntsiab lus ntawm kev ua haujlwm, tsuas yog saib cov qauv ntawm lub cuab yeej. Thawj qhov ntawm yog lub rectifier, uas yog sib sau ua ke ntawm semiconductor diodes. Qhov no yog ib tug choj Circuit Court rau converting ib los yog peb theem AC rau DC. Rau kev siv nyob rau hauv tsev, nws yog ib qhov tsim nyog los xaiv cov qauv ntawm chastotnikov, cov tswv yim uas txuas nrog ib-theem alternating tam sim no network. Qhov kev xaiv tau txuas nrog qhov tseeb tias nws yog qhov teeb meem thiab tsis muaj txiaj ntsig los ua lub network peb-theem hauv tsev ntiag tug, vim tiasYuav tsum siv cov ntsuas hluav taws xob ntau dua.
Main inverter Cheebtsam
Ib tug tau hais me ntsis txog qhov zaus converter Circuit Court yog dab tsi. Tab sis rau kev kawm kom ntxaws, koj yuav tsum xav txog nws kom ntxaws ntxiv. Nyob rau hauv thawj theem, transformation yog nqa tawm - rectification ntawm alternating tam sim no. Txawm hais tias muaj pes tsawg theem tau muab rau cov tswv yim (peb lossis ib qho), ntawm qhov tso zis ntawm lub rectifier koj tau txais qhov tsis tu ncua unipolar (ib qho ntxiv thiab ib qho rho tawm) voltage ntawm 220 volts. Qhov ntawd yog pes tsawg ntawm theem thiab xoom.
Ua raws li lub lim lim, uas pab tshem tawm tag nrho cov khoom sib txawv ntawm cov khoom kho tam sim no. Thiab nyob rau theem kawg, inversion tshwm sim - ib qho alternating tam sim no yog tsim los ntawm cov tam sim no ncaj qha siv fais fab transistors tswj los ntawm microcontroller. Raws li txoj cai, zaus converters rau asynchronous motors muaj ib tug monochrome LCD zaub, uas qhia qhov tsim nyog tsis.
Kuv puas tuaj yeem tsim lub cuab yeej kuv tus kheej?
Kev tsim cov cuab yeej no cuam tshuam ntau yam teeb meem. Koj yuav tsum kawm cov hauv paus ntawm microcontroller programming txhawm rau nthuav dav lub peev xwm ntawm lub cuab yeej. Nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account tag nrho cov kev cai yooj yim. Piv txwv li, qhov muaj peev xwm ntawm kev kaw tsis siv neeg thaum muaj xwm txheej ceev thaum lub siab tshaj plaws tso cai tam sim no siv los ntawm lub tshuab hluav taws xob ntau dhau. Ua li no, nws yog ib qho tsim nyog yuav tsum tau nruab tam sim no transformers ntawm cov zis, uas yuav ua rau kev soj ntsuam tas li. Kuj yuav tsum muaj kev ua haujlwmpassive cua txias ntawm tag nrho cov hwj chim hais ntawm lub system - diodes thiab transistors, raws li zoo raws li tig tawm lub ntaus ntawv nyob rau hauv cov ntaub ntawv ntawm overheating. Tsuas yog tom qab ntawd tuaj yeem hloov pauv zaus rau asynchronous motors ua haujlwm yam xyuam xim.
