Vim li cas cov cuab yeej txhuam tsis tau ua nrov dua?

Raws li qhov kev thov rau cov cuab yeej hluav taws xob nce txhua hnub, feem ntau cov cuab yeej siv hluav taws xob tau tsom mus rau kev tsim cov cuab yeej hluav taws xob nrog cov yam ntxwv siab heev los sib tw nrog cov npe nrov.Cov cuab yeej muaj zog nrogtxhuam tsis txhuamthev naus laus zis tau dhau los ua neeg nyiam ntawm DIYers, cov kws tshaj lij, thiab cov cuab yeej siv hluav taws xob rau kev lag luam, uas tsis yog tshiab.

Thaum lub zog dimmer nrog lub peev xwm hloov pauv tam sim no (AC) mus rau tam sim no ncaj qha (DC) tau tsim nyob rau xyoo 1960, cov cuab yeej siv hluav taws xob nrog brushless motors tau nthuav dav.Magnetism-raws li thev naus laus zis tau siv hauv cov cuab yeej los ntawm cov tuam txhab fais fab;lub roj teeb hluav taws xob ces sib npaug cov khoom siv hluav taws xob raws li cov hlau nplaum.Brushless motors tau tsim tsis muaj qhov hloov pauv mus rau kis tam sim no, thiab cov tuam txhab siv hluav taws xob feem ntau nyiam tsim thiab faib cov cuab yeej nrog brushless motors vim lawv muag zoo dua li cov cuab yeej txhuam.

Cov cuab yeej hluav taws xob nrog brushless motors tsis tau nrov mus txog thaum xyoo 1980s.Brushless lub cev muaj zog tuaj yeem tsim kom muaj zog tib yam li txhuam cov motors ua tsaug rau cov hlau nplaum ruaj khov thiab cov khoom siv hluav taws xob siab.Brushless motor txoj kev loj hlob tsis tau nres nyob rau hauv peb lub xyoos dhau los.Raws li qhov tshwm sim, cov tuam txhab tsim hluav taws xob thiab cov xa khoom tam sim no muab cov cuab yeej siv hluav taws xob ntau dua.Yog li ntawd, cov neeg siv khoom tau txais txiaj ntsig los ntawm cov txiaj ntsig tseem ceeb xws li muaj ntau haiv neeg thiab cov nqi kho mob qis dua vim qhov no.

Brushed thiab Brushless Tsav, Dab tsi yog qhov txawv?Qhov twg yog Siv Ntau?

Brushed Tsav

Lub armature ntawm brushed DC lub cev muaj zog ua raws li ib tug ob-ncej electromagnet nrog ib tug configuration ntawm qhov txhab hlau coils.Lub commutator, ib tug neeg kho tshuab tig hloov, hloov cov directionality ntawm tam sim no ob zaug ib lub voj voog.Lub electromagnet tus ncej thawb thiab rub tawm tsam cov hlau nplaum nyob ib puag ncig sab nraud ntawm lub cev muaj zog, tso cai rau tam sim no hla yooj yim dua los ntawm armature.Raws li tus commutator's ncej hla cov hlau nplaum ruaj khov' ncej, armature's electromagnet's polarity yog thim rov qab.

Brushless Tsav

Ib lub cev tsis muaj zog, ntawm qhov tod tes, muaj cov hlau nplaum ruaj khov raws li nws cov rotor.Nws kuj tseem siv peb theem ntawm kev tsav tsheb kauj vab nrog rau lub ntsej muag ntse uas saib xyuas txoj haujlwm rotor.Lub sensor xa cov cim qhia rau tus maub los thaum nws pom lub rotor orientation.Cov coils yog ces qhib rau hauv ib txoj kev los ntawm tus maub los, ib tug los ntawm ib tug.Muaj qee qhov zoo rau cov cuab yeej siv hluav taws xob nrog cov cuab yeej siv tshuab tsis siv neeg, cov txiaj ntsig zoo li hauv qab no:

• Vim tsis muaj txhuam hniav, muaj tsawg dua tus nqi tu.
• Brushless thev naus laus zis ua tau zoo ntawm txhua qhov nrawm nrog cov ntsuas ntsuas.
• Brushless thev naus laus zis nce qhov kev ua tau zoo ntawm cov cuab yeej.
• Brushless thev naus laus zis muab cov cuab yeej nrog ntau yam zoo tshaj thermal.
• Brushless thev naus laus zis ua rau lub suab nrov qis dua thiab muaj qhov nrawm dua.

Brushless motors tam sim no nrov dua li brushed motors.Ob leeg, ntawm qhov tod tes, tuaj yeem siv ntau yam kev siv.Hauv cov khoom siv hauv tsev thiab tsheb, cov tshuab txhuam DC kuj tau siv dav.Lawv tseem muaj kev lag luam muaj zog vim tias muaj peev xwm hloov pauv qhov sib piv ntawm lub zog-rau-ceev, uas tsuas yog muaj nyob rau hauv brushed motors.

Txaus siab rau Brushless Technology nrog Series ntawm Cov Cuab Yeej Hluav Taws Xob

Tiankon tau siv brushless motors nyob rau hauv nws qhov tseeb ntau yam ntawm 20V cov cuab yeej ruaj khov, ib yam li lwm cov npe nrov xws li Metabo, Dewalt, Bosch, thiab lwm yam.Txhawm rau muab cov neeg siv kev xyiv fab ntawm kev siv cov cuab yeej siv hluav taws xob tsis muaj zog, Tiankon, uas yog lub chaw tsim khoom siv hluav taws xob, tau tso tawm ib kab ntawm brushless mini lub kaum sab xis grinders, tuag grinders, cuam tshuam kev xyaum, ntswj ntsia hlau, cuam tshuam wrenches, teb hammers, blowers, hedge trimmers, thiab nyom trimmers, tag nrho cov uas khiav ntawm ib lub roj teeb.Xav txog tias muaj peev xwm ua tau txhua yam nrog ib lub roj teeb: sawing, drilling, trimming, polishing, thiab lwm yam.Raws li qhov tshwm sim ntawm muaj cov roj teeb sib xws, tsis yog tsuas yog kev ua haujlwm tau zoo dua qub, tab sis lub sijhawm thiab qhov chaw yuav raug cawm dim thiab.Yog li ntawd, koj tuaj yeem them koj cov cuab yeej ib zaug thiab ua tiav ntau pua txoj haujlwm nrog tsuas yog ib lub roj teeb uas ua haujlwm nrog tag nrho koj cov cuab yeej.

Cov cuab yeej brushless no los nrog ob lub roj teeb muaj zog: 20V roj teeb pob nrog 2.0AH Li-ion roj teeb thiab 20V roj teeb pob nrog 4.0AH Li-ion roj teeb.Yog tias koj xav ua haujlwm rau lub sijhawm ntev, 20V 4.0Ah roj teeb pob yog qhov kev xaiv zoo tshaj plaws vim tias nws siv zog rau cov cuab yeej siv sijhawm ntev dua.Txwv tsis pub, 20V roj teeb pob nrog 2.0Ah Li-ion roj teeb yog qhov kev xaiv ntse dua yog tias kev soj ntsuam nrog cov cuab yeej tsis siv sijhawm ntev.
