步進馬達

步進馬達是將完整旋轉劃分為多個等量步進的無刷直流電動馬達。它在每一步進會旋轉特定的增量距離。執行的步進數量用於控制馬達軸的旋轉角度。


步進馬達有內建輸出步進,因此本身具備一些控制位置的能力。它能非常精確控制步進馬達旋轉的量與速度。馬達執行的步進數量等於控制器發出的脈衝指令數量。步進馬達旋轉的距離與速度會與其脈衝指令的數量和頻率成比例。


步進馬達控制器可以是開放式迴圈或封閉式迴圈。兩者之間的差異是:開放式迴圈系統假定轉子依循的旋轉磁場是固定的,所以將固定功率提供給馬達。封閉式迴圈系統依據馬達的負載種類,以反餽來調整功率。大部分的馬達應用採用開放式迴圈系統,因為比較簡單而且便宜。


步進馬達有數項優點勝過其他類型的馬達。最突顯的優點之一就是非常精確的定位能力。經過多次旋轉後,仍然能到達相同的目標位置。標準的步進馬達擁有 +/-5% 的步進角度精確度。多個步進的誤差不會累積。
