style="text-indent:25px">調(diào)速風(fēng)機優(yōu)勢：逆變器容量低，因此逆變器成本低。無刷直流電動機需要矩形波電流，逆變器持續(xù)運行時的電流額定值指的就是這個矩形波的峰值。感應(yīng)電機需要正弦波電流，逆變器持續(xù)運行時的電流額定值一般指的是這個正弦波的有效值。為保持逆變器對電動機電流的控制能力，逆變器直流電壓與電動機感應(yīng)電動勢間應(yīng)有足夠的差值。因此無刷直流電動機梯形波感應(yīng)電動勢和感應(yīng)電動機正弦波感應(yīng)電動勢可以達(dá)到的峰值都受到逆變器直流電壓的限制。在這種情況下，若假定無刷直流電動機和感應(yīng)電動機電流的峰值相等，則前者功率輸出要比后者高出33%，也就是說，同一臺整流器/逆變器可以驅(qū)動比感應(yīng)電機輸出功率高出33%的無刷直流電動機。濟南空氣懸浮風(fēng)機哪家質(zhì)量好離心風(fēng)機包括有蝸殼離心風(fēng)機和無蝸殼離心風(fēng)機。</p><div
