两相混合式步进电机步距角一般为3.6度、1.8度，五相混合式步进电机步距角一般为0.72度、0.36度。也有一些的步进电机步距角更小。如四通公司生产的一种用于慢走丝机床的步进电机，其步距角为0.09度；德国百格拉公司（bergerlahr）生产的三相混合式步进电机其步距角可通过拨码开关设置为1.8、0.9、0.72、0.36、0.18、0.09、0.072、0.036，兼容了两相和五相混合式步进电机的步距角。

交流伺服电机的控制精度由电机轴后端的旋转编码器保证。以松下全数字式交流伺服电机为例，对于带标准2500线编码器的电机而言，由于驱动器内部采用了四倍频技术，其脉冲当量为360度/10000=0.036度。对于带17位编码器的电机而言，驱动器每接收217=131072个脉冲电机转一圈，即其脉冲当量为360度/131072=9.89秒。是步距角为1.8度的步进电机的脉冲当量的1/655。
