西門子直流調速工作原理簡單介紹:
直流調速器就是調節直流電動機速度的設備,上端和交流電源連接,下端和直流電動機連接,直流調速器
將交流電轉化成兩路輸出直流電源,一路輸入給直流電機礪磁定子),
一路輸入給直流電機電樞(轉子),直流調速器通過控制電樞直流電壓來調節直流電動機轉速。同時直流電動機給調速器一個反饋電流,調速
器根據反饋電流來判斷直流電機的轉速情況,必要時修正電樞電壓輸出,以此來再次調節電機的轉速。
五、直流電機的調速方案一般有下列
3種方式:
1、改變電樞電壓;
2、改變激磁繞組電壓;
3、改變電樞 回路電阻。
最常用的是調壓調速系統,即
1(改變電樞電壓).
六、一種模塊式直流電機調速器,集電源、控制、驅動電路于一體,采用立體結構布局,控制電路采用微
功耗元件,用光電耦合器實現電流、電壓的隔離變換,電路的比例常數、積分常數和微分常數用PID適配器調整。該調速器體積小、重量輕,可單獨使用也可直接安裝在直流電機上構成一體化直流調速電機,可
具有調速器所應有的一切功能。
