20V Lithium roj teeb cordless laum

Qhov sib txawv tseem ceeb ntawm lithium laum lub cev muaj zog thiab lub cev tsis muaj zog yog nyob hauv lawv cov kev tsim kho thiab kev ua haujlwm:

Brushed Tsav: Ib txwm siv lithium drills feem ntau siv brushed motors. Cov motors no muaj cov txhuam hniav uas xa lub zog mus rau lub commutator, uas nyob rau hauv lem tig lub cev muaj zog armature. Raws li lub cev muaj zog spines, cov txhuam hniav ua rau lub cev sib cuag nrog lub commutator, tsim kev sib txhuam thiab ua kom sov. Qhov kev sib txhuam thiab hnav ntawm cov txhuam hniav thiab commutator tuaj yeem ua rau txo qis kev ua haujlwm thiab kev ua neej nyob ntev.

Brushless Tsav: Txhuam txhuam tsis muaj lub cev muaj zog, ntawm qhov tod tes, tsis txhob siv txhuam los yog lub tshuab xa hluav taws xob. Hloov chaw, lawv cia siab rau cov tswj hluav taws xob kom tswj tau qhov ntws ntawm hluav taws xob mus rau lub cev muaj zog windings. Qhov kev tsim no tshem tawm qhov xav tau ntawm cov txhuam hniav, txo kev sib txhuam thiab hnav. Yog li ntawd, brushless motors feem ntau muaj kev ua haujlwm siab dua, kev ua neej ntev dua, thiab nyob ntsiag to piv rau cov motors brushed. Lawv kuj nyiam xa ntau lub zog rau tib qhov loj thiab qhov hnyav, ua rau lawv nrov nrov hauv cov cuab yeej hluav taws xob xws li xyaum xyaum.

Hauv cov ntsiab lus, thaum ob hom motors tuaj yeem ua lub zog lithium laum, brushless motors muaj qhov zoo hauv kev ua haujlwm, lifespan, thiab kev ua haujlwm. Txawm li cas los xij, lawv tuaj yeem tuaj ntawm tus nqi pib ntau dua piv rau kev xyaum nrog txhuam cov motors.

Lub lithium laum txhuam lub cev muaj zog feem ntau yog hais txog hom lub cev muaj zog siv hauv cov cuab yeej siv hluav taws xob xws li kev xyaum thiab txhuam txhuam. Lithium yog hais txog hom roj teeb uas siv lub laum, thaum lub cev muaj zog nws tus kheej yuav yog lub cev muaj zog lossis tsis muaj DC lub cev muaj zog.

Brushed motors muaj carbon txhuam uas xa hluav taws xob tam sim no mus rau lub rotating armature, thaum brushless motors siv hluav taws xob controllers xa hluav taws xob mus rau windings. Brushless motors yuav ua tau zoo dua thiab ruaj khov dua li brushed motors, tab sis lawv kuj tseem kim dua.

Cov roj teeb lithium-ion feem ntau yog siv rau hauv cov cuab yeej hluav taws xob vim lawv lub zog siab ceev thiab cov khoom siv rov ua tau zoo, muab lub sijhawm ua haujlwm ntev dua piv rau lwm hom roj teeb. Thaum ua ke nrog lub cev tsis muaj zog, lithium-ion-powered laum tuaj yeem muab kev ua haujlwm siab thiab lub neej ntev dua.
