Hauv lub neej niaj hnub, los ntawm cov khoom ua si hluav taws xob mus rau lub tsheb fais fab,hluav taws xob motors tuaj yeem hais tau txhua qhov chaw. Cov motors no tuaj nyob rau hauv ntau hom xws li brushed DC motors, brushless DC (BLDC) motors, thiab ruaj khov hlau nplaum synchronous motors (PMSM). Txhua hom muaj nws cov yam ntxwv tshwj xeeb thiab qhov sib txawv, ua rau lawv haum rau kev siv sib txawv.
Cia peb pib nrog brushed DC motors. Cov motors tau nyob ib puag ncig ntev thiab tau siv dav hauv cov ntawv thov uas yooj yim thiab siv tau zoo yog qhov tseem ceeb. Brushed DC motors siv txhuam thiab ib lub commutator los muab lub zog rau lub cev muaj zog rotor. Txawm li cas los xij, cov txhuam hniav no nyiam hnav dhau sijhawm, ua rau txo qis kev ua haujlwm thiab kev ntseeg siab. Tsis tas li ntawd, brushed DC motors tsim hluav taws xob ntau lub suab nrov vim cov txhuam hniav tsis tu ncua kev sib cuag nrog cov commutator, txwv lawv siv hauv qee yam kev siv.
Ntawm qhov tod tes, BLDC motors, raws li lub npe qhia, tsis txhob siv txhuam rau kev sib hloov. Hloov chaw, lawv siv cov khoom siv hluav taws xob hloov hluav taws xob los tswj lub cev muaj zog cov theem tam sim no. Qhov no brushless tsim muaj ntau yam zoo dua brushed DC motors. Ua ntej, BLDC motors muaj kev ntseeg siab dua thiab muaj txiaj ntsig zoo dua vim tias tsis muaj txhuam los hnav. Qhov kev txhim kho hauv kev ua tau zoo no txhais mus rau hauv kev txuag hluav taws xob thiab kev siv roj teeb ntau ntxiv hauv cov ntawv thov portable. Ntxiv mus, qhov tsis muaj cov txhuam hniav tshem tawm cov suab nrov hluav taws xob, tso cai rau kev ua haujlwm ntsiag to, ua rau BLDC motors zoo tagnrho rau cov ntawv thov uas lub suab nrov yog qhov tseem ceeb, xws li tsheb fais fab thiab drones.
Thaum nws los txog rau PMSM, lawv qhia qhov zoo sib xws nrog BLDC motors tab sis muaj qhov sib txawv me ntsis hauv lawv cov kev tsim kho thiab kev tswj hwm. PMSM motors kujsiv cov hlau nplaum ruaj khov hauv lub rotor, zoo ib yam li BLDC motors. Txawm li cas los xij, PMSM motors muaj sinusoidal back-EMF waveform, whereas BLDC motors muaj ib tug trapezoidal waveform. Qhov sib txawv ntawm waveform no cuam tshuam rau kev tswj lub tswv yim thiab kev ua haujlwm ntawm cov motors.
PMSM motors muaj ntau qhov zoo dua BLDC motors. Lub sinusoidal rov qab-EMF waveform inherently ua smoother torque thiab ua hauj lwm, ua rau txo qis cogging thiab kev co. Qhov no ua rau PMSM motors zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab ua haujlwm zoo, xws li cov neeg hlau thiab cov tshuab ua haujlwm. Tsis tas li ntawd, PMSM motors muaj lub zog ntau dua, txhais tau tias lawv tuaj yeem xa ntau lub zog rau lub cev muaj zog piv rau BLDC motors.
Nyob rau hauv cov nqe lus ntawm kev tswj, BLDC motors feem ntau yog tswj los ntawm ib tug rau-kauj ruam commutation tswv yim, thaum PMSM motors yuav tsum tau ntau complex thiab sophisticated tswj algorithms. PMSM motors feem ntau xav tau txoj hauj lwm thiab kev tawm tswv yim ceev rau kev tswj kom meej. Qhov no ntxiv qhov nyuaj thiab tus nqi rau lub cev muaj zog tswj tab sis tso cai rau kev ceev thiab kev tswj lub zog zoo dua, zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab raug.
Anhui Mingteng Permanent Magnet Electrical & tshuab Equipment Co., Ltd. yog lub tuam txhab high-tech niaj hnub uas koom nrog kev tshawb fawb thiab kev tsim kho, tsim khoom, muag, thiab kev pabcuam ntawm cov hlau nplaum ruaj khov. Peb muaj cov kws tshaj lij kev tshawb fawb thiab kev tsim kho pab pawg tshaj 40 lub tshuab hlau nplaum ruaj khov, nkag siab tag nrho cov kev cai ntawm ntau yam khoom siv tsav tsheb hauv ntau qhov kev lag luam. Lub tuam txhab cov hlau nplaum ruaj khov synchronous motors tau ua tiav ntawm ntau yam khoom xws li kiv cua, twj tso kua mis, siv conveyors, pob zeb, mixers, crushers, scraper machines, thiab roj extraction tshuab nyob rau hauv ntau yam xws li cement, mining, steel, thiab hluav taws xob, ua tiav cov txiaj ntsig zoo txuag hluav taws xob thiab tau txais kev qhuas dav. Peb tab tom nrhiav rau pem hauv ntej kom ntau thiab ntau Minteng PM motors tau siv rau ntau yam kev ua haujlwm kom txuag tau lub zog thiab txo kev siv rau kev lag luam!
