.負(fù)載電流

電動機(jī)采用變頻器運(yùn)轉(zhuǎn)同采用工頻電源運(yùn)轉(zhuǎn)相比，由于變頻器輸出電壓、電流中所含諧波的影響，電動機(jī)的效率、功率因數(shù)將降低，電流將增加(同一負(fù)載約增10%)。電動機(jī)負(fù)載非常輕時，即使電動機(jī)電流在變頻器額定電流以內(nèi)，也不能使用比電動機(jī)容量小很多的變頻器，這是因?yàn)殡妱訖C(jī)的電抗隨電動機(jī)的容量不同，即使電動機(jī)負(fù)載相同，電動機(jī)容量越大，其脈動電流值也就越大，因而有可能超過變頻器的過流耐量。

2.低速運(yùn)轉(zhuǎn)時的轉(zhuǎn)矩特性

標(biāo)準(zhǔn)電動機(jī)采用變頻器低速運(yùn)轉(zhuǎn)時，對于U/f的轉(zhuǎn)距控制，各頻率下運(yùn)轉(zhuǎn)電流大體同電動機(jī)額定頻率下的運(yùn)轉(zhuǎn)電流一樣，因此主要應(yīng)控制電動機(jī)的銅損造成的溫升。在這種低速情況下，即使電動機(jī)的銅損大體與額定轉(zhuǎn)速時相同，但由于轉(zhuǎn)速變低，電動機(jī)冷卻效果變差，電動機(jī)定子繞組溫升就變大，所以與此溫升相應(yīng)地減小運(yùn)轉(zhuǎn)轉(zhuǎn)矩，降低銅損使用。
