MVI56-101M在工頻附近，電機(jī)狀態(tài)較為穩(wěn)定，但是如果在 40Hz的頻率下，尤其是 20至 30Hz的范圍內(nèi)，電機(jī)的電流會(huì)以 10至 20Hz左右的周期震蕩，此時(shí)的峰值如果過高，那么電機(jī)的整個(gè)運(yùn)行狀態(tài)會(huì)受到嚴(yán)重影響。針對(duì)該情況展開分析，對(duì)于異步電動(dòng)機(jī)來說，其如果處于轉(zhuǎn)差率為零的狀態(tài)，那么其暫態(tài)的轉(zhuǎn)矩正負(fù)變化就會(huì)存在不穩(wěn)定影響因素。更為重要的是逆變器驅(qū)動(dòng)下的轉(zhuǎn)矩脈動(dòng)， V/F的暫態(tài)變化都會(huì)引起較為明顯的轉(zhuǎn)矩波動(dòng)，這些都有可能會(huì)演變成為振動(dòng)，甚至?xí)掷m(xù)振動(dòng)。這種形勢(shì)下的轉(zhuǎn)矩脈動(dòng)與諧波電流等因素之間具有關(guān)聯(lián)性，如果變頻電機(jī)在運(yùn)行時(shí)，其運(yùn)行狀態(tài)不穩(wěn)定，切忌不能夠只是單純的認(rèn)為電機(jī)或者變頻器存在故障問題，而是要根據(jù)電機(jī)以及變頻器的參數(shù)，對(duì)兩者進(jìn)行綜合分析，這樣才能夠?qū)收线M(jìn)行合理的判斷。
