5.何为步进电机的相数，我应该选择几相的步进电机？步进电机的相数是指电机内部的线圈组数，目前常用的有二相、三相、四相、五相步进电机。电机相数不同，其步距角也不同，一般二相电机的步距角为0.9°/1.8°、三相的为0.75°/1.5°等、五相的为0.36°/0.72°。在没有细分驱动器时，用户主要*选择不同相数的步进电机来满足自己步距角的要求。如果使用细分驱动器，则‘相数’将变得没有意义，用户只需在驱动器上改变细分数，就可以改变步距角。 　　
6.我正准备选择五相混合式步进电机，请问有何建议？五相混合式步进电机处于正在淘汰状态，所以我们建议：如果您一定要用五相的步距角(0.36°），请您选用二相混合式步进电机和配套的细分驱动器，在5细分状态下的步距角同样为0.36°，并且细分后的步距角比五相固有的步距角更均匀、精度更高、运行更平稳、出力更大。

油漆工完成施工后，木工再进行安装工作。电工灯具以及开关插座面板的安装：应该在墙面刷涂料或贴墙纸的工作完成后，再进行灯具的安装及开关插座面板的安装工作。曾经有过这样的事例：某公司施工时，为节省人员开支，于是在工序安排上让电工过早安装了开关插座，结果后面的油漆工人贴墙纸时，没有注意保护开关插座，用壁纸刀裁开关插座面板的开口时，不小心把面板划花了。卫生洁具以及浴室五金的安装：由于我们目前的家装行业整体管理水平还很低，施工现场的工人的素质普遍较差。

窗五金分类一推拉窗的五金配件铝合金或塑钢推拉窗的导轨是在窗框型材上直接成型，滑轮系统固定在窗扇底部。推拉窗的滑动是否自如不仅取决于滑轮系统的质量，而且与型材平直度和加工精度以及窗框安装精度有关。积尘对轨道和滑轮的磨损也会影响推拉窗的开关功能。推拉窗的锁一般是插销式锁，这种锁会因为安装精度不高、积尘等原因而失效。推拉窗的拉手通常由插销式锁的开关部分所代替，但也有高档推拉窗将窗扇型材作出一个弧型，起拉手的作用。
