如何讓直流無刷減速電機實現控制
通常我們把直(zhi)流電(dian)(dian)機(ji)(ji)(ji)(ji)分為(wei)有(you)刷電(dian)(dian)機(ji)(ji)(ji)(ji)和無刷電(dian)(dian)機(ji)(ji)(ji)(ji)兩(liang)(liang)種。直(zhi)流無刷減速電(dian)(dian)機(ji)(ji)(ji)(ji)制(zhi)動(dong)是(shi)通常利用電(dian)(dian)機(ji)(ji)(ji)(ji)自身進行(xing)快速制(zhi)動(dong)有(you)兩(liang)(liang)種簡單的(de)辦法，一種是(shi)能(neng)(neng)耗制(zhi)動(dong)，一種是(shi)短接(jie)制(zhi)動(dong)，能(neng)(neng)耗制(zhi)動(dong)是(shi)把電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)動(dong)能(neng)(neng)消(xiao)耗在外部(bu)制(zhi)動(dong)電(dian)(dian)阻上，短接(jie)制(zhi)動(dong)是(shi)把電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)動(dong)能(neng)(neng)消(xiao)耗在電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)定子(zi)繞組上。顯然能(neng)(neng)耗制(zhi)動(dong)對(dui)于(yu)減少電(dian)(dian)機(ji)(ji)(ji)(ji)發熱更加有(you)利
