Qee cov lus qhia txog brushless DC lub cev muaj zog

1. Brushless DC lub cev muaj zog: Piv nrog brushless DC lub cev muaj zog, nws yog tus cwj pwm los ntawm kev ua haujlwm ntev, kev tswj ceev ceev, suab nrov me me thiab lub zog loj, thiab lwm yam.brushless DC lub cev muaj zognrog rau sab nraud rotor siv rau ntau lub shafts.
2. Qhov sib npaug dynamic ntawm sab nraud rotor ntawm lub cev muaj zog thiab cov khoom xaiv ntawm cov kabmob txiav txim siab feem ntau ntawm qhov kev ua tau zoo ntawm lub cev muaj zog.Yog hais tias muaj teeb meem tshwm sim nyob rau hauv ob qhov chaw, yuav pom tseeb txawv txawv suab los yog kev co thaum lub sij hawm high-ceev kev sib hloov ntawm lub cev muaj zog, uas yog heev yooj yim mus kuaj.
3. Cov khoom siv coil ntawm thebrushless DC motoris "copper core" lossis "aluminium core".Kev xaiv cov khoom siv ntawm cov tub ntxhais hlau cuam tshuam rau kev ua haujlwm sab hauv, kev pab cuam lub neej thiab cua sov dissipation ntawm lub cev muaj zog, yog li nws yog ib qho tseem ceeb heev. Tsis tas li ntawd, tus naj npawb ntawm cov kauj thiab cov xov tooj winding ncaj qha cuam tshuam rau cov zis hluav taws xob ntawm lub cev muaj zog. .
4. Thebrushless DC motor muaj qhov tseem ceeb tshaj qhov ntsuas tus nqi xws li, kv tsim nyog muaj ntau yam uas tuaj yeem cuam tshuam, xws li cov khoom siv hlau nplaum, cov khoom siv ntawm cov tub ntxhais hlau, coil tooj ntawm cov lem, tsau nyob rau hauv ob qho tib si yav dhau los, feem ntau yog me me. tus lej hloov ntau dua kv tus nqi, qhov ntau npaum li cas, tus lej hloov, qhov tsawg dua tus nqi kv, lwm qhov yog lub coil winding ntawm tus naj npawb ntawm shares, txiav txim siab qhov tam sim no los ntawm lub ntim, nyob rau hauv cov xwm txheej ntawm qhov tsis tu ncua voltage. , tam sim no, qhov ntau dua lub ntuj yuav ua rau muaj zog tso zis ntau dua, tab sis tsis yog qhov tseeb.
5. Qhov zawj tag nrho ntawm cov txhuam tsis muaj DC motoris feem ntau tswj tau ntawm 70% thiab 80%, uas yog qhov zoo tshaj plaws, siab dhau thiab feem ntau tsis tuaj yeem entangled, qis dhau yuav raug loosened vim kev co, cuam tshuam rau rwb thaiv tsev thiab kev pab cuam lub neej luv.Tsis tas li ntawd, muaj huab cua ntau hauv qhov zawj, uas cuam tshuam rau cov cua sov dissipation (qhov thermal conductivity ntawm huab cua yog qhov phem tshaj tooj liab).
