變頻器與伺服的區別

2020-08-28

YI、LIANGZHEDEGONGTONGDIAN:



伺服的基本概念是準確、精確、快速定位。變頻是伺服控制的一個必須的內部環節,伺服驅動器中同樣存在變頻(要進行無級調速)。但伺服將電流環速度環或者位置環都閉合進行控制,這是很大的區別。除此外,伺服電機的構造與普通電機是有區別的,要滿足快速響應和準確定位。現在市面上流通的交流伺服電機多為永磁同步交流伺服,但這種電機受工藝限制,很難做到很大的功率,十幾KW以上的同步伺服價格及其昂貴,這樣在現場應用允許的情況下多采用交流異步伺服,這時很多驅動器就是高端變頻器,帶編碼器反饋閉環控制。所謂伺服就是要滿足準確、精確、快速定位,只要滿足就不存在伺服變頻之爭。

3、對應交流同步和異步電機變頻器伟德体育就有相映的同步變頻器和異步變頻器,伺服電機也有交流同步伺服和交流異步伺服,當然變頻器里交流異步變頻常見,伺服則交流同步伺服常見。
