描述
風(fēng)機(jī)泵類負(fù)載是典型的平方轉(zhuǎn)矩負(fù)載,低速下負(fù)載非常小,并與轉(zhuǎn)速平方成正比,通用變頻器與標(biāo)準(zhǔn)電動(dòng)機(jī)的組合最合適。這類負(fù)載對(duì)變頻器的性能要求不高,只要求經(jīng)濟(jì)性和可靠性,所以選擇具有U/f=const控制模式的變頻器即可,如FR-A540(L)。如果將變頻器輸出頻率提高到工頻以上時(shí),功率急劇增加,有時(shí)超過電動(dòng)機(jī)變頻器的容量,導(dǎo)致電動(dòng)機(jī)過熱或不能運(yùn)轉(zhuǎn),故對(duì)這類負(fù)載轉(zhuǎn)矩,不要輕易將頻率提高到工頻以上。
