　　 比喻步进电机每转一圈为200个脉冲,如果步进电机驱动器细分为32,那么步进电机驱动器需要输出6400个脉冲步进电机才转一圈。

　　 通常步进电机细分有2,4,8,16,32,62,128,256,512....

　　 在国外，对于步进电机系统，主要采用二相混合式步进电机及相应的细分步进电机驱动器。但在国内，广大用户对“细分”还不是特别了解，有的只是认为，细分是为了提高步进电机精度，其实不然，细分主要是改善步进电机的运行性能，现说明如下：

水槽是厨房装修中必不可少的配套厨具产品，主要用于洗菜、淘米、洗碗等等，一般主要有单盆、又盆之分；并且根据安装方式的不同也有台上盆、台平盆、台下盆等等类型，目前应用于厨房中的水槽多以不锈钢材质居多，使用过程中不仅不易生锈，而且易于打理。厨房水槽如何安装是很多业主比较关心的问题，今天小编带大家一起去了解下关于厨房水槽的安装技巧吧。厨房水槽安装技巧之：台上盆安装台上盆类型的水槽安装比较简朴，只需按安装图纸在台面预置开孔，后将盆放置于孔中，用玻璃胶将缝隙填实即可，使用时台面的水不会顺缝隙下流，所以在家庭中使用得比较多厨房水槽安装技巧之：台平盆安装这类型的厨房水槽采用台平盆安装方法，实现水槽与台面无缝安装的效果。

GCr15SiMo和GCr18Mo钢分别是在1986～1995年期间先后开发的高淬透性轴承钢，其目的是为了适应国民经济的发展，特别是重型机械、矿山机械、采掘钻井机械等大型化、重型化的发展需求。这些领域对大型轴承的品种、规格和数量的需求越来越多，轴承尺寸增加，要求轴承内外套圈的有效壁厚和滚体直径也随之加大，用GCr15SiMn钢的淬透性、淬硬性及轴承的寿命满足不了实际需要。GCr15SiMo钢开发的基本思路为：通过研究Si对Cr-Mo系SKF25及Mo对Cr-Si-Mn系的GCr15SiMn钢各项性能的影响，而筛选出淬透性J6≥25mm，同时淬硬性等各项性能良好的钢种；GCr18Mo钢则是以德国钢号1CrMo7（相当于SKF24）为基础而开发的适宜于贝氏体等温淬火的钢种，其淬透性为88端淬J6值为18mm。
