FX3U-422-0

簡單點說就是交流電機的控制中使用了變頻技術。交流變頻電機實際上是一種靠調節交流電頻率來調速的電機，調整交流電頻率要靠變頻器，電機本身不會變頻，在很多要求不高的場合就是拿普通電機加變頻器調速當交流變頻電機使用。

　　電機加上變頻調速器后有嗡嗡聲是怎么回事？

　　所說的“嗡”的聲音，那是因為變頻器輸出波形載波頻率引起的，通常如果你用的變頻器是固定載波的話，此時電機發出的是尖叫，對人耳刺激比較大，那你可以通過調節載波頻率（變頻器技術手冊功能表里有這個功能參數）。載波頻率越高聲音越小，但載波越高的話此時電機就越容易發熱。所以要根據發熱程序和發出的聲音一起考慮你所使用的載波頻率，一般出廠時都是在額定電流下合適的載波頻率，一般情況下你不需要去改動他。 而如果變頻器用的是隨機載波的話，那電機發出的“嗡”的聲音將比較柔和，但聲音一般會比固定載波的聲音要好聽點。呵呵（更容易讓人接受），如果你不會接受的話，或者說你想靜音運行的話，你也可以把載波頻率向上調，調到滿意為止。
