淮(huai)安租賃發電(dian)機-口(kou)碑

<淮安>逸爾(er)機(ji)械設備(bei)有(you)限公(gong)司(si)(si)經過近幾年來的業務(wu)(wu)發展(zhan)，本公(gong)司(si)(si)已具備(bei)淮(huai)安大(da)型發電機(ji)出(chu)(chu)租(zu)/租(zu)賃類行業的實用技術，完善的服務(wu)(wu)體系(xi)，開拓出(chu)(chu)國(guo)內的廣大(da)應用市，服務(wu)(wu)于全國(guo)。

只是(shi)(shi)由于無(wu)刷(shua)直流(liu)(liu)(liu)(liu)采用(yong)了(le)電(dian)(dian)(dian)子換向(xiang)，所以(yi)(yi)(yi)要有(you)(you)數(shu)字控制(zhi)(zhi)才(cai)可以(yi)(yi)(yi)實(shi)現了(le)，而有(you)(you)刷(shua)直流(liu)(liu)(liu)(liu)是(shi)(shi)通(tong)過碳刷(shua)換向(xiang)的(de)(de)，利用(yong)可控硅等傳統模擬(ni)電(dian)(dian)(dian)路都可以(yi)(yi)(yi)控制(zhi)(zhi)，比較(jiao)(jiao)簡(jian)單。 三、性(xing)能差異上的(de)(de)區別： 1、有(you)(you)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)結構簡(jian)單、開發時(shi)(shi)間(jian)久、技術成熟： 早在十九紀(ji)誕生電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)的(de)(de)時(shi)(shi)候(hou)，產生的(de)(de)實(shi)用(yong)性(xing)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)就是(shi)(shi)無(wu)刷(shua)形(xing)式，即(ji)交(jiao)流(liu)(liu)(liu)(liu)鼠籠(long)式異步電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)，這種電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)在交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)產生以(yi)(yi)(yi)后得到了(le)廣泛的(de)(de)應(ying)用(yong)。但是(shi)(shi)，異步電(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)(ji)(ji)(ji)有(you)(you)許多無(wu)法(fa)克服的(de)(de)缺陷，以(yi)(yi)(yi)致電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)技術發展緩慢。 2、直流(liu)(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)響應(ying)速(su)度快(kuai)，起(qi)(qi)動(dong)(dong)(dong)扭(niu)矩大(da)： 直流(liu)(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)響應(ying)速(su)度快(kuai)，起(qi)(qi)動(dong)(dong)(dong)扭(niu)矩大(da)，變速(su)平(ping)穩，速(su)度從零到 幾乎感覺不到振動(dong)(dong)(dong)，起(qi)(qi)動(dong)(dong)(dong)時(shi)(shi)可帶動(dong)(dong)(dong)更大(da)的(de)(de)負(fu)荷。無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)阻大(da)（感抗），所以(yi)(yi)(yi)功率(lv)因素小(xiao)，起(qi)(qi)動(dong)(dong)(dong)扭(niu)矩相(xiang)對較(jiao)(jiao)小(xiao)，起(qi)(qi)動(dong)(dong)(dong)時(shi)(shi)有(you)(you)嗡嗡聲，并伴隨著強烈震(zhen)動(dong)(dong)(dong)，起(qi)(qi)動(dong)(dong)(dong)時(shi)(shi)帶動(dong)(dong)(dong)負(fu)荷較(jiao)(jiao)小(xiao)。 3、直流(liu)(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)運行平(ping)穩，起(qi)(qi)、制(zhi)(zhi)動(dong)(dong)(dong)效(xiao)果好： 有(you)(you)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)是(shi)(shi)通(tong)過調(diao)(diao)壓調(diao)(diao)速(su)，所以(yi)(yi)(yi)起(qi)(qi)動(dong)(dong)(dong)和制(zhi)(zhi)動(dong)(dong)(dong)平(ping)穩，恒速(su)運行時(shi)(shi)也(ye)平(ping)穩。無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)(ji)通(tong)常是(shi)(shi)數(shu)字變頻(pin)控制(zhi)(zhi)，先將交(jiao)流(liu)(liu)(liu)(liu)變成直流(liu)(liu)(liu)(liu)，直
