Hauv chav ua lag luam thiab chav ua noj ua noj thiab ua noj ua haus hauv tsev, sib xyaw ua ke, raws li cov khoom siv tseem ceeb, cuam tshuam rau kev ua tau zoo. Kev ua txhaum ntawm ob lub tshuab ua txhaum ntawm ob qho kev sib txawv tam sim no (DC) thiab hloov kho tam sim no (AC) qhov sib txawv ntawm cov ntsiab cai ua haujlwm ntawm lawv cov kev ua haujlwm. Kab lus no yuav ua kev txheeb xyuas cov qauv kev sib piv ntawm cov ntsiab lus, ua tau zoo rau cov ntawv thov.
1. Cov qauv sib txawv hauv cov tshuab hluav taws xob
DC Cov Motors Siv Hlau Hlau nplaum thiab Arthature Windings los tsim lub zog thiab cov tshuaj txhuam thiab txhuam txhuam kom ua tiav cov lus hloov tshiab. Cov ntaub pua uas raug DC raug ua haujlwm muaj kev siv hluav taws xob muaj kev ua haujlwm ntawm} v, thiab meej ceev kev cai yog tiav los ntawm Mem Tes Dav Hlau Tes Haujlwm (PWM). AC cov motors yog nyob ntawm cov hauv paus ntsiab lus ntawm induction induction. Lub rotating sib nqus daim teb tsim los ntawm lub stator winding drives lub squirrel tawb rotor, thiab ceev tau nruj me ntsis synchronized nrog lub zog hluav taws xob.
Cov txheej txheem sib txawv no ua rau DC lub cev muaj zog tswj Circuit Court kom suav nrog tus qauv Rectifier thiab cov tswj hwm ceev, thaum lub AC lub cev muaj feem cuam tshuam nrog lub zog hluav taws xob. Cov ntaub ntawv xeem ntawm cov khoom siv ntawm DC cov motors nrog tib lub zog tuaj yeem ncav cuag 300% ntawm cov nqi sib tw, uas yog qhov muaj peev xwm ntau dua li 150% pib peev txheej AC MOTORS.
2. Kev txheeb xyuas cov kev ntsuas ntawm cov khoom tsis ua haujlwm
Nyob rau hauv cov nqe lus ntawm dynamic kev kho kom haum ntawm DC mixers tuaj yeem ncav cuag ± 1RPM, thiab lawv txhawb tus mob stepless ceev hloov pauv ntau yam ntawm {rpm. Cov ntaub ntawv ntsuas ntawm qee hom ntawm cov lag luam DC mixers qhia tau tias nws tsuas yog siv sijhawm li 1000 teev, uas yog 40% nrawm dua li tib cov qauv. Nyob rau hauv cov nqe lus ntawm lub zog ntom ntom, lub ntim-rau-fais fab piv tau mus txog 3.5W /M³ tuaj yeem 3.5W /M³, uas yog 60% siab dua li ntawm Active A motors.
Qhov kev sib piv ntawm kev ua kom muaj zog ntawm DC tau ua tau zoo ntawm DC cov kev ua tau zoo ntawm AC lub cev muaj zog yog tswj hwm tau ntawm {}}}% thauj khoom. Hauv kev sim ua haujlwm tas mus li, qhov ntsuas kub tau nkhaus ntawm AC cov motors yog tsuas yog 45 tus lej qis dua li ntawm DC cov ntaub ntawv, muaj kev cuam tshuam zoo dua thermal stability.
