從電動(dòng)機(jī)與負(fù)載相連而成的機(jī)械系統(tǒng),為防止振動(dòng),必須使整個(gè)系統(tǒng)不與電動(dòng)機(jī)產(chǎn)生的電磁力諧波。負(fù)載匹配及對(duì)策生產(chǎn)機(jī)械的種類繁多,性能和工藝要求各異,其轉(zhuǎn)矩特性不同,因此應(yīng)用變頻器前首先要搞清電動(dòng)機(jī)所帶負(fù)載的性質(zhì),即負(fù)載特性,然后再選擇變頻器和電動(dòng)機(jī)。負(fù)載有三種類型:恒轉(zhuǎn)矩負(fù)載、風(fēng)機(jī)泵類負(fù)載和恒功率負(fù)載。不同的負(fù)載類型,應(yīng)選不同類型的變頻器。(3)恒轉(zhuǎn)矩負(fù)載恒轉(zhuǎn)矩負(fù)載又分為摩擦類負(fù)載和位能式負(fù)載。摩擦類負(fù)載的起動(dòng)轉(zhuǎn)矩一般要求額定轉(zhuǎn)矩的150%左右,制動(dòng)轉(zhuǎn)矩一般要求額定轉(zhuǎn)矩的左右,所以變頻器應(yīng)選擇具有恒定轉(zhuǎn)矩特性,而且起動(dòng)和制動(dòng)轉(zhuǎn)矩都比較大,過載時(shí)間和過載能力大的變頻器,如FR-A540系列。位能負(fù)載一般要求大的起動(dòng)轉(zhuǎn)矩和能量回饋功能。
