　　对实际步距角的作用：在没有细分驱动器时，用户主要靠选择不同相数的步进电机来满足自己对步距角的要求。如果使用细分驱动器，则用户只需在驱动器上改变细分数，就可以大幅度改变实际步距角，步进电机的“相数”对改变实际步距角的作用几乎可以忽略不计。
　步进电机是一种将电脉冲转化为角位移的执行机构。通俗一点讲：当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度(即步进角)。您可以通过控制脉冲个数来控制角位移量，从而达到准确的目的;同时您可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。以下给大家介绍的是步进电机的未来发展趋势：

随着我国民用住宅的大规模发展，住宅建筑日趋高层化，面临建筑采光和外观美化的需要，门窗的单体面积日趋大型化和墙体化，导致其雨水渗漏题目越来越凸起。同时，铝门窗的雨水渗漏现象在其它材质的门窗中也广泛存在并有相似的情形，有些则更为严峻。因而有必要对铝门窗的雨水渗漏原因进行分析并处理，这不但对解决铝门窗雨水渗漏题目，也对其它种类门窗的雨水渗有着同样的指导意义。铝门窗雨水渗漏的主要原因大体上可分为四大类。一：设计过程中门窗本身结构存在缺陷引起，二：加工和安装过程中达不到质量要求引起，三:材料及附件材质分歧格引起，四:与洞口墙体连结部位的密封处理不当引起。

过热组织中残留奥氏体增多，尺寸稳定性下降。由于淬火组织过热，钢的晶体粗大，会导致零件的韧性下降，抗击性能下降，关节轴承的寿命也降低。过热严重甚至会造成淬火裂纹。欠热淬火温度偏低或冷却不良却会在显微组织中产生超过标准规定的托氏体组织，称为欠热组织，它使硬度下降，耐磨性急剧降低，影响回转支撑轴承寿命。淬火裂纹轴承零件在淬火冷却过程中因内应力所形成的裂纹称为淬火裂纹。造成这种裂纹的原因有：由于淬火加热温度过高或冷却太急。
