style="text-indent:25px">(3)變頻調(diào)速拖動系統(tǒng)。這是一種理想的拖動系統(tǒng)，且可使用籠型感應(yīng)電動機(jī)(或同步電動機(jī))，具有申級調(diào)速拖動系統(tǒng)效率高的優(yōu)點。如采用脈寬調(diào)制(PWM)變頻調(diào)速，還可提高系統(tǒng)的功率因數(shù)和減小諳波。晶體管PWM電壓型交流一直流一交流變頻調(diào)速可用于100~200 kw設(shè)備，晶閘管電流型交流一直流一交流變頻調(diào)速可用于幾百千瓦至2000 kw大型設(shè)備。交流一交流直接變頻調(diào)速(600r/min以下)可用于幾千千瓦以上的特大型設(shè)備(同步電動機(jī)).這種拖動系統(tǒng)的控制電路復(fù)雜，總投資較高，甚至高達(dá)電磁調(diào)速電動機(jī)的4~5倍。系統(tǒng)和大功率無換向器電動機(jī)拖動系統(tǒng)。 (1)變極對數(shù)調(diào)速拖動系統(tǒng).這種系統(tǒng)的控制電路簡單、占地面積小、維護(hù)方便、價格低廉，但系有級調(diào)速，一般*有2檔或3檔轉(zhuǎn)速。如果將此系統(tǒng)與定子調(diào)壓或電磁調(diào)速電動機(jī)結(jié)合起來，可以得到既減少轉(zhuǎn)差損耗，又在相當(dāng)范圍內(nèi)平滑調(diào)速的較高效率的拖動系統(tǒng)。 (2)串級調(diào)速拖動系統(tǒng)。這種系統(tǒng)適用于燒線轉(zhuǎn)子感應(yīng)電動機(jī)。優(yōu)點是變流設(shè)備容量(轉(zhuǎn)差功率)小，比其他無級調(diào)速方案經(jīng)濟(jì);缺點是必須使用繞線轉(zhuǎn)子感應(yīng)電動機(jī)，功率因數(shù)低，增加電機(jī)損耗，**商轉(zhuǎn)速降低。現(xiàn)已開發(fā)出多種改善功率因數(shù)的線路.雙饋電機(jī)可克服一般申級調(diào)速的一些缺點</p><div
