汕頭300kw大型(xing)發電機出租(zu)_省心省錢

<汕頭>逸爾機械(xie)設備有限(xian)公司自成立以來(lai)(lai)，一直以“誠信(xin)服(fu)務、誠信(xin)合作”的經(jing)營理(li)念為基(ji)本準則，贏(ying)得了廣大(da)客戶(hu)以及汕頭發電機回收企業(ye)的信(xin)任和支持(chi)。歡迎廣大(da)新老(lao)客戶(hu)前來(lai)(lai)洽談。

只是(shi)由(you)于(yu)無(wu)(wu)刷(shua)直(zhi)(zhi)流(liu)采用了(le)(le)電(dian)子換向，所(suo)以(yi)要有(you)(you)(you)(you)(you)數字控(kong)制(zhi)(zhi)才可(ke)(ke)以(yi)實現了(le)(le)，而有(you)(you)(you)(you)(you)刷(shua)直(zhi)(zhi)流(liu)是(shi)通(tong)過碳(tan)刷(shua)換向的(de)，利用可(ke)(ke)控(kong)硅(gui)等傳統(tong)模擬電(dian)路都可(ke)(ke)以(yi)控(kong)制(zhi)(zhi)，比較簡(jian)單(dan)。 三、性能差(cha)異(yi)(yi)上的(de)區別(bie)： 1、有(you)(you)(you)(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)結構簡(jian)單(dan)、開(kai)發(fa)時(shi)(shi)間久(jiu)、技術成熟： 早在十九紀誕生電(dian)機(ji)(ji)(ji)的(de)時(shi)(shi)候，產(chan)生的(de)實用性電(dian)機(ji)(ji)(ji)就是(shi)無(wu)(wu)刷(shua)形式，即(ji)交流(liu)鼠籠式異(yi)(yi)步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)，這種電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)在交流(liu)電(dian)產(chan)生以(yi)后得到(dao)了(le)(le)廣泛的(de)應用。但是(shi)，異(yi)(yi)步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)有(you)(you)(you)(you)(you)許(xu)多無(wu)(wu)法克(ke)服的(de)缺陷，以(yi)致電(dian)機(ji)(ji)(ji)技術發(fa)展緩慢。 2、直(zhi)(zhi)流(liu)有(you)(you)(you)(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)響(xiang)應速(su)度快(kuai)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩(ju)(ju)大(da)： 直(zhi)(zhi)流(liu)有(you)(you)(you)(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)響(xiang)應速(su)度快(kuai)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩(ju)(ju)大(da)，變(bian)(bian)速(su)平(ping)(ping)穩(wen)，速(su)度從零到(dao) 幾乎感覺不到(dao)振動(dong)(dong)(dong)(dong)(dong)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)可(ke)(ke)帶動(dong)(dong)(dong)(dong)(dong)更大(da)的(de)負荷(he)。無(wu)(wu)刷(shua)電(dian)機(ji)(ji)(ji)起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)阻大(da)（感抗），所(suo)以(yi)功率(lv)因素小(xiao)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)扭矩(ju)(ju)相(xiang)對較小(xiao)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)有(you)(you)(you)(you)(you)嗡(weng)嗡(weng)聲，并伴隨(sui)著強烈(lie)震動(dong)(dong)(dong)(dong)(dong)，起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)帶動(dong)(dong)(dong)(dong)(dong)負荷(he)較小(xiao)。 3、直(zhi)(zhi)流(liu)有(you)(you)(you)(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)運行平(ping)(ping)穩(wen)，起(qi)(qi)(qi)、制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)效(xiao)果好： 有(you)(you)(you)(you)(you)刷(shua)電(dian)機(ji)(ji)(ji)是(shi)通(tong)過調壓調速(su)，所(suo)以(yi)起(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)和制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)平(ping)(ping)穩(wen)，恒速(su)運行時(shi)(shi)也平(ping)(ping)穩(wen)。無(wu)(wu)刷(shua)電(dian)機(ji)(ji)(ji)通(tong)常是(shi)數字變(bian)(bian)頻控(kong)制(zhi)(zhi)，先將(jiang)交流(liu)變(bian)(bian)成直(zhi)(zhi)流(liu)，直(zhi)(zhi)
