6ES7223-1BF22-0XA0電樞磁動勢對氣隙永磁主磁場的影響,稱為電樞反應。直流無刷電機的電樞反應比較復雜。電樞反應磁動勢會使氣隙主磁場波形發生畸變,氣隙主磁場的磁通密度不再是空載時的方波,反電動勢也隨之畸變,從而引起轉矩波動。現代直流無刷電機大多采用高性能的稀土永磁材料,若采用瓦片形表面貼裝式,則電樞反應對氣隙主磁場的影響比較微弱。這是因為電樞反應磁路要經過氣隙和永磁體,永磁材料的磁導率與空氣的磁導率是非常接近的,這就使電樞反應磁路的磁阻很大,交軸電樞反應的磁通很小,其對氣隙主磁場的影響可以忽略不計。但是對于內置式轉子結構,電樞反應的影響則不能夠忽略。
6ES7223-1BF22-0XA0機械加工缺陷和材料的不一致也是引起直流無刷電機轉矩波動的重要原因之一。例如電機機械加工及裝配時產生的尺寸和形位偏差,定子沖片各槽分布不均勻,定子內、外圓偏心,定、轉子同軸度偏差等產生的單邊磁拉力;軸承系統的摩擦轉矩不均勻;轉子位置傳感器定位不準導致的轉矩波動;各相繞組參數不對稱及電子元器件性能參數的差異而導致的轉矩波動;磁路中各零件材料特別是每個磁極永磁體性能不一致而產生的轉矩波動等。因此,提高加工制造水平也是減少轉矩波動的重要措施。Siemens Simatic S5 6ES5 946-3UA22 E:04 Warranty
