·步距角精度︰步进电机转动一个步距角度的理论值与实际值的误差。用百分比表示∶误差/步距角*100%。
·失步:电机运转时运转的步数，不等于理论上的步数。也可以叫做丢步，一般都是因负载太大或者是频率过快。
·失调角︰转子齿轴线偏移定子齿轴线的角度，电机运转必存在失调角，由失调角产生的误差，采用细分驱动是不能解决的。
·大空载起动频率:在不加负载的情况下，能够直接起动的大频率。·大空载的运行频率:电机不带负载的高转速频率。
·运行转矩特性︰电机的动态力矩取决于电机运行时的平均电流（而非静态电流)，平均电流越大，电机输出力矩越大，即电机的频率特性越硬。
·电机正反转控制:通过改变通电顺序而改变电机的正反转。
1.步进电机的精度大概为步距角的3-5%，且不会积累
2.步进电机的外表允许的高温度:一般步进电机会因外表温度过高而产生磁性减小，从而会导致力矩较小，一般来说磁性材料的退磁点都在摄氏130度以上，有的甚至高达摄氏200
度以上，所以步进电机外表温度在摄氏80-90度完全正常。
3.步进电机的转矩与速度成反比，速度越快力矩越小。
4.低速时步进电机可以正常启动，高速时不会启动，并伴有啸叫声。步进电机的空载启动频率是固定的，如果高于这个频率电机不能被启动并且会产生丢步或者堵转。
