，可ke以yi很hen好hao的de保bao證zheng低di速su輸shu出chu力li矩ju。但dan是shi，直zhi流liu電dian機ji的de結jie構gou，決jue定ding了le直zhi流liu電dian機ji的de維wei護hu工gong作zuo量liang比bi較jiao大da
，需xu定ding期qi檢jian修xiu。所suo以yi，在zai最zui新xin的de控kong製zhi係xi統tong中zhong
，已yi開kai始shi逐zhu步bu使shi用yong交jiao流liu變bian頻pin調tiao速su係xi統tong。把ba變bian頻pin器qi用yong於yu可ke逆ni紮zha機ji的de傳chuan動dong，早zao在zai幾ji年nian前qian已yi有you使shi用yong
，但dan那na時shi進jin口kou變bian頻pin器qi價jia格ge很hen高gao

，在zai推tui廣guang上shang受shou到dao了le一yi定ding的de限xian製zhi。所suo以yi，該gai係xi統tong選xuan擇ze了le新xin一yi代dai高gao性xing能neng、高性價比的安邦信G11係列電流矢量控製變頻器，該變頻器在1HZ時即有150%的輸出力矩
，在用閉環矢量控製時，0HZ時即有150%的輸出力矩。完全滿足可逆紮機的要求。　　
    該係統主紮機配備了G11- 315KW的變頻器，工作於無PG矢量控製方式。該主機的速度決定了整個係統的工作速度，調速方式采用電位器調速
，控製指令由PLC控製。收放卷采用了G11- 93KW變頻器，加PG卡與編碼器，采用有PG矢量控製，工作於力矩控製方式，力矩大小由人工根據實際需要調整。收放卷的控製用PLC的輸出端控製。

    小結
    由於變頻調速係統有許多優點
，已在許多行業逐步替代直流調速係統。安邦信G11係列變頻器是重載型變頻器，過載能力強，保護完善
，速度穩定

，精度高，用在紮鋼行業是非常理想的選擇。
