Dab tsi yog qhov kev tswj xyuas qhov hluav taws xob ntawm DC brushless reducer

DC brushless reducer tsis siv hom kev hloov pauv tam sim no, tab sis siv lub inverter Circuit Court hloov cov kev taw qhia tam sim no. Thaum tswj lub DC brushless lub cev muaj zog, feem ntau siv lub inverter Circuit Court. Tsis tas li ntawd, tus nqi tam sim no tuaj yeem hloov kho los ntawm kev hloov qhov ntxiv voltage ntawm txhua theem los ntawm inverter Circuit Court. Hauv kev tswj hluav taws xob, PWM (Pulse Width Modulation=Pulse Width Modulation) feem ntau siv. PWM yog ib txoj hauv kev hloov qhov voltage los ntawm kev kho cov mem tes ON / OFF lub sij hawm ntev. Nws lub luag haujlwm tseem ceeb yog los kho qhov sib piv ntawm lub sijhawm mus rau off-time (lub luag haujlwm lub voj voog). Yog hais tias tus nqi conduction yog siab, tib yam li qhov nce qhov voltage yuav tau. Yog tias ON tus nqi qis dua, cov txiaj ntsig zoo ib yam li txo qhov voltage yuav raug tsim.

Kuj tseem muaj cov khoos phis tawj nruab nrog rau cov khoom siv tshwj xeeb los siv PWM. Thaum ua haujlwm sine yoj tswj, nws yog ib qho tsim nyog los tswj qhov voltage ntawm peb theem, yog li lub software yog me ntsis nyuab dua li 120-degree energization tswj ntawm tsuas yog ob theem. Lub inverter yog ib qho tseem ceeb ntawm kev tsav tsheb DC brushless lub cev muaj zog. Inverters kuj siv nyob rau hauv AC motors, tab sis nws muaj peev xwm txiav txim tau hais tias lub thiaj li hu ua" inverter hom" Hauv cov khoom siv hauv tsev siv brushless DC motors. Hloov ON lub sij hawm nyob rau hauv ib lub sij hawm ntawm lub sij hawm los hloov tus nqi zoo ntawm qhov voltage. Raws li ON lub sij hawm ntawm kev sib raug zoo ntawm PWM cov zis thiab cov zis voltage nce, tus nqi zoo yog ze rau qhov thov voltage (ON).
