·步距角精度︰步進電機轉動一個步距角度的理論值與實際值的誤差。用百分比表示∶誤差/步距角*100%。

·失步:電機運轉時運轉的步數，不等于理論上的步數。也可以叫做丟步，一般都是因負載太大或者是頻率過快。

·失調角︰轉子齒軸線偏移定子齒軸線的角度，電機運轉必存在失調角，由失調角產生的誤差，采用細分驅動是不能解決的。

·大空載起動頻率:在不加負載的情況下，能夠直接起動的大頻率?！ご罂蛰d的運行頻率:電機不帶負載的高轉速頻率。

·運行轉矩特性︰電機的動態(tài)力矩取決于電機運行時的平均電流（而非靜態(tài)電流)，平均電流越大，電機輸出力矩越大，即電機的頻率特性越硬。

·電機正反轉控制:通過改變通電順序而改變電機的正反轉。

1.步進電機的精度大概為步距角的3-5%，且不會積累

2.步進電機的外表允許的高溫度:一般步進電機會因外表溫度過高而產生磁性減小，從而會導致力矩較小，一般來說磁性材料的退磁點都在攝氏130度以上，有的甚至高達攝氏200

度以上，所以步進電機外表溫度在攝氏80-90度完全正常。

3.步進電機的轉矩與速度成反比，速度越快力矩越小。

4.低速時步進電機可以正常啟動，高速時不會啟動，并伴有嘯叫聲。步進電機的空載啟動頻率是固定的，如果高于這個頻率電機不能被啟動并且會產生丟步或者堵轉。
