Dab tsi yog brushless DC lub cev muaj zog? Dab tsi yog cov yam ntxwv ntawm brushless lub cev muaj zog?

los ntawm Hall effect ICs los tswj kev sib hloov ntawm ON / OFF lub xeev ntawm transistors nyob rau hauv lub voj voog tsav, yog li zam kev siv cov neeg kho tshuab kev sib cuag thiab txo cov kev tu ncua.

II. Ruaj khov ceev ceev

Kev sib piv tsis tu ncua thiab kev hloov kho: Brushless motors ua tiav kev tswj ceev ruaj khov vim tias lawv tsis tu ncua sib piv cov txheej txheem ceev nrog cov lus qhia ceev los ntawm lub cev muaj zog los kho qhov voltage thov rau lub cev muaj zog. Yog li ntawd, txawm tias muaj kev hloov pauv hauv kev thauj khoom, lub cev tsis muaj zog tuaj yeem hloov kho tam sim ntawm qhov qis qis mus rau qhov teeb tsa ceev thiab ua haujlwm ntawm qhov nrawm nrawm. Nyob rau hauv sib piv, peb -theem induction motors tswj los ntawm zaus converters tsis muaj tswv yim tswj, ua rau ib tug tseem ceeb ceev poob thaum lub load nce.

III. Txuag Zog

Txo cov kev poob qis: Lub rotor ntawm lub cev tsis muaj zog DC siv cov hlau nplaum ruaj khov, uas pab txo qis rotor thib ob poob. Yog li ntawd, piv rau peb lub-theem induction lub cev muaj zog nrog zaus converter tswj, lub hwj chim noj ntawm lub brushless lub cev muaj zog yog txo los ntawm kwv yees li 23%, ua rau lub zog txuag nyob rau hauv lub ntaus ntawv.

IV. Nyias tsim thiab siab zog

Daim ntawv thov cov hlau nplaum tas mus li: Kev siv cov hlau nplaum tas mus li hauv lub rotor ntawm lub cev tsis muaj zog tso cai rau ob qho tib si nyias tsim thiab cov khoom siv hluav taws xob siab. Piv txwv li, piv rau hom 90 peb-theem induction lub cev muaj zog, tag nrho qhov ntev ntawm lub cev tsis muaj zog tuaj yeem ua kom luv dua li 75 hli thaum ua tiav 1.3 npaug ntawm cov zis hluav taws xob. Qhov no pab txhawb rau lub miniaturization ntawm lub cuab yeej.

V. Kev tiv thaiv muaj nuj nqi

Ua kom muaj kev nyab xeeb ntawm qhov system: Brushless DC motors tau nruab nrog overcurrent, theem poob, thiab kev tiv thaiv kev ua haujlwm tsis zoo. Cov haujlwm tiv thaiv no pab tiv thaiv kev nyab xeeb ntawm cov cuab yeej siv thiab ua kom nws ruaj khov thaum ua haujlwm.

VI. Wide Speed ​​Control Range

Haum rau Ntau Daim Ntawv Thov: Kev tswj ceev ntawm DC brushless motors yog dav dua li ntawm AC ceev - tswj cov motors thiab zaus converters. Tsis zoo li AC ceev- tswj lub cev muaj zog, uas muaj kev txwv lub zog ntawm qhov nrawm, tsis muaj lub cev muaj zog yog tsim rau cov ntawv thov uas xav tau qee qhov torque los ntawm qis mus rau qhov siab.

Hauv cov ntsiab lus, DC brushless motors, nrog rau lawv cov txij nkawm- kev ua haujlwm pub dawb, kev tswj ceev ceev, kev siv hluav taws xob, kev siv hluav taws xob tsawg, cov khoom siv hluav taws xob siab, cov yam ntxwv tiv thaiv, thiab kev tswj ceev nrawm, tau pom muaj ntau daim ntawv thov nyob rau hauv ntau qhov chaw.
