1、步进电机是一种作为控制用的特种电机, 它的旋转是以固定的角度(称为"步距角")一步一步运行的, 其特点是没有积累误差(精度为), 所以广泛应用于各种开环控制。步进电机的运行要有一电子装置进行驱动, 这种装置就是步进电机驱动器, 它是把控制系统发出的脉冲信号转化为步进电机的角位移, 或者说: 控制系统每发一个脉冲信号, 通过驱动器就使步进电机旋转一步距角。所以步进电机的转速与脉冲信号的频率成正比。所以，控制步进脉冲信号的频率，可以对电机调速；控制步进脉冲的个数，可以对电机目的；
2、步进电机通过细分驱动器的驱动，其步距角变小了，如驱动器工作在10细分状态时，其步距角只为‘电机固有步距角‘的十分之一，也就是说：‘当驱动器工作在不细分的整步状态时，控制系统每发一个步进脉冲，电机转动1.8°；而用细分驱动器工作在10细分状态时，电机只转动了0.18° ‘，这就是细分的基本概念。 细分功能完全是由驱动器靠控制电机的相电流所产生，与电机无关。

铝合金装饰轨道：市场上较多，区别品质只要看他的壁厚就可以，好的管壁相对较厚要在1.5MM-2MM.其次看拉环的设计，许多铝合金装饰轨的拉环在轨道的上部和下部有拉槽，实际上是假性的装饰轨设计，真正的装饰杆的拉环是直接在杆上滑动的，差的装饰杆采用再生塑料的拉环，制造工艺粗糙。。钢管装饰杆：俗称铁艺杆，表面处理有喷涂，电镀，直径有16MM，19MM，2MM，25MM等，品质看喷涂和电镀的质量，安装脚的钢板厚度，和管壁的厚度。

再用嵌缝膏嵌填封闭镜子周边。嵌压法嵌压法是采用不锈钢、铝合金或木线条做玻璃镜的边框，用钉固法先把边框与墙基层固定，再把玻璃镜镶嵌在边框内。这种方法适宜大面积玻璃镜的安装固定。嵌压的具体做法如下：首先按边框压条尺寸弹线、排孔、打眼。按弹好的线先固定下部边框压条，钉子的间距以1~15厘米为宜，以增加底部支撑强度。然后用乳白胶把毛毯粘贴在基层上。再把镜子镶嵌在下部边框的压条内，找正与墙面贴平，安装上部边框压条及两侧边框压条。
