Xyoo 1895, German overtone ua lub ntiaj teb thawj DC xyaum.Lub tsev yog ua los ntawm cov hlau cam khwb cia thiab tuaj yeem laum lub qhov 4 hli hauv cov phaj hlau.Tom qab ntawd peb-theem fais fab zaus (50Hz) hluav taws xob xyaum tau tshwm sim, tab sis lub cev muaj zog tsis ua tiav los ntawm 3000r / min.Xyoo 1914, cov cuab yeej hluav taws xob uas tau tsav los ntawm ib-theem series excitation motors tau tshwm sim, thiab lub zog ceev tau mus txog ntau dua 10000r / min.Xyoo 1927, ib qho khoom siv hluav taws xob nruab nrab nrog lub zog siv hluav taws xob ntawm 150-200Hz tau tshwm sim.Nws tsis tsuas yog muaj qhov zoo ntawm kev kub ceev ntawm ib-theem series lub cev muaj zog, tab sis kuj muaj qhov zoo ntawm cov qauv yooj yim thiab txhim khu kev qha ntawm peb-theem fais fab zaus lub cev muaj zog, tab sis nws yuav tsum tau siv los ntawm qhov nruab nrab zaus tam sim no., siv yog txwv.

Lub tshuab hluav taws xob yog cov cuab yeej siv tshuab uas siv lub tshuab hluav taws xob lossis lub tshuab hluav taws xob ua lub zog thiab tsav lub taub hau ua haujlwm los ntawm kev sib kis.Raws li "National Economic Industry Classification" (GB/T4754-2011), lub tuam txhab kev lag luam belongs rau sub-category "Pneumatic thiab Fais Fab Tool Manufacturing" (code C3465) ntawm lub dav qeb "General Equipment Manufacturing".Cov cuab yeej hluav taws xob feem ntau yog muab faib ua hlau txiav cov cuab yeej hluav taws xob, cov cuab yeej sib tsoo fais fab, cov cuab yeej siv hluav taws xob sib dhos thiab cov cuab yeej hluav taws xob railway.Cov cuab yeej siv hluav taws xob feem ntau yogCordless Brushless Rauj Laum DC2808/20V, hluav taws xob grinders, siv grinders, hluav taws xob wrenches, hluav taws xob screwdrivers, hluav taws xob rauj, pob zeb vibrators, hluav taws xob planers, lub kaum sab xis grinders, hluav taws xob saws, sanders, lub kaum sab xis grinders, blowers, polishing tshuab, sander, thiab lwm yam.

Cov kev lag luam sab saud ntawm cov cuab yeej hluav taws xob yog cov khoom siv raw khoom (xws li cov ntawv silicon steel, enameled tooj liab xov hlau, txhuas qhov chaw, plastics, thiab lwm yam), thiab kev lag luam yog rhiab heev rau cov nqi hloov pauv ntawm cov ntaub ntawv raw li saum toj no.Daim ntawv thov cov cuab yeej siv hluav taws xob suav nrog kev tsim kho, kho kom zoo nkauj, ua ntoo, ua hlau thiab lwm yam kev lag luam.Kev cuam tshuam los ntawm tsoomfwv txoj cai ntawm kev txhawb nqa kev xav tau hauv tsev thiab kev nqis peev hauv kev tsim kho vaj tse, yav tom ntej txoj kev loj hlob ntawm txoj kev tsim kho thiab kev lag luam hlau ua lag luam tau cog lus tseg, yog li tsav qhov kev xav tau ntawm cov cuab yeej hluav taws xob hauv kev lag luam.
