各位大神好，我想咨詢(xún)兩個(gè)問(wèn)題：
1：松下1.5KW的伺服因為功率較大，需不需要外加哪些安全保護措施，比如終端能耗回聲電阻什么的，聽(tīng)銷(xiāo)售說(shuō)前端也要加個(gè)保護的什么東東，到底需不需要？
2：因為380V和220V電費不一樣，而我這個(gè)案子用到一個(gè)松下1.5KW伺服和一個(gè)普通三相380電機，如果伺服用家用220V電有沒(méi)有更省電費?

     謝謝！

1.5KW的伺服功率不算大,可以采用電抗之類(lèi)進(jìn)線(xiàn)裝置.
省電這個(gè)不好說(shuō),就普通電機來(lái)說(shuō)效率都達到90%左右,選擇合適容量,用伺服,變頻之類(lèi)并不會(huì )節省多少電.沒(méi)有浪費,能節省下來(lái)多少電呢.
