4、使用變頻器控制高速電動(dòng)機(jī)時(shí)，由于高速電動(dòng)機(jī)的電抗小，會(huì)產(chǎn)生較多的高次諧波。而這些高次諧波會(huì)使變頻器的輸出電流值增加。因此，選擇用于高速電動(dòng)機(jī)的變頻器時(shí)，應(yīng)比普通電動(dòng)機(jī)的變頻器稍大一些。
5、變頻器用于變極電動(dòng)機(jī)時(shí)，應(yīng)充分注意選擇變頻器的容量，使其大額定電流在變頻器的額定輸出電流以下。另外，在運(yùn)行中進(jìn)行極數(shù)轉(zhuǎn)換時(shí)，應(yīng)先停止電動(dòng)機(jī)工作，否則，會(huì)造成電動(dòng)機(jī)空轉(zhuǎn),惡劣時(shí)會(huì)造成變頻器損壞。
6、驅(qū)動(dòng)防爆電動(dòng)機(jī)時(shí)，變頻器沒有防爆構(gòu)造，應(yīng)將變頻器設(shè)置在危險(xiǎn)場(chǎng)所之外。
