<淮安>逸爾機(ji)械設(she)備有限公司

淮安租賃發(fa)電(dian)機-口碑

<淮安>逸(yi)爾機械設(she)備有限公司(si)經過(guo)近幾年(nian)來的(de)(de)業務發展，本(ben)公司(si)已具備淮安大(da)型發電機出租/租賃(lin)類行業的(de)(de)實用(yong)技(ji)術(shu)，完善的(de)(de)服務體系，開拓出國(guo)內的(de)(de)廣大(da)應用(yong)市，服務于(yu)全國(guo)。

只(zhi)是(shi)由于無刷(shua)直(zhi)流(liu)(liu)(liu)采(cai)用(yong)(yong)了(le)電(dian)子換向(xiang)，所以要有(you)(you)數字控制(zhi)才可(ke)以實現了(le)，而(er)有(you)(you)刷(shua)直(zhi)流(liu)(liu)(liu)是(shi)通過碳刷(shua)換向(xiang)的(de)(de)，利用(yong)(yong)可(ke)控硅(gui)等傳統模擬(ni)電(dian)路(lu)都可(ke)以控制(zhi)，比較(jiao)簡單。 三、性能差異上的(de)(de)區(qu)別： 1、有(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)結構簡單、開發時(shi)(shi)間(jian)久、技術(shu)成(cheng)熟(shu)： 早在十九紀誕生(sheng)電(dian)機(ji)(ji)(ji)的(de)(de)時(shi)(shi)候，產生(sheng)的(de)(de)實用(yong)(yong)性電(dian)機(ji)(ji)(ji)就是(shi)無刷(shua)形式，即交(jiao)流(liu)(liu)(liu)鼠(shu)籠(long)式異步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)，這(zhe)種電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)在交(jiao)流(liu)(liu)(liu)電(dian)產生(sheng)以后得到(dao)了(le)廣泛的(de)(de)應用(yong)(yong)。但(dan)是(shi)，異步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)有(you)(you)許多無法克服的(de)(de)缺陷，以致電(dian)機(ji)(ji)(ji)技術(shu)發展緩(huan)慢(man)。 2、直(zhi)流(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)響應速(su)度(du)快，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩大(da)： 直(zhi)流(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)響應速(su)度(du)快，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩大(da)，變速(su)平穩(wen)，速(su)度(du)從零到(dao) 幾乎(hu)感覺不(bu)到(dao)振動(dong)(dong)(dong)(dong)(dong)，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)可(ke)帶動(dong)(dong)(dong)(dong)(dong)更大(da)的(de)(de)負荷。無刷(shua)電(dian)機(ji)(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)阻大(da)（感抗），所以功(gong)率因素小，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩相對較(jiao)小，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)有(you)(you)嗡嗡聲(sheng)，并伴隨著強烈震動(dong)(dong)(dong)(dong)(dong)，起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)帶動(dong)(dong)(dong)(dong)(dong)負荷較(jiao)小。 3、直(zhi)流(liu)(liu)(liu)有(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)運行(xing)平穩(wen)，起(qi)(qi)、制(zhi)動(dong)(dong)(dong)(dong)(dong)效(xiao)果好： 有(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)是(shi)通過調壓調速(su)，所以起(qi)(qi)動(dong)(dong)(dong)(dong)(dong)和(he)制(zhi)動(dong)(dong)(dong)(dong)(dong)平穩(wen)，恒速(su)運行(xing)時(shi)(shi)也(ye)平穩(wen)。無刷(shua)電(dian)機(ji)(ji)(ji)通常是(shi)數字變頻控制(zhi)，先將交(jiao)流(liu)(liu)(liu)變成(cheng)直(zhi)流(liu)(liu)(liu)，直(zhi)
