步进电机的振动噪音由步进电机本体引起的原因如下:

　(1)激磁电源的高次谐波成分。

　(2)齿槽转矩。

　(3)径向吸引力引起的转子变形产生的振动噪音.

　(4)定子与端盖的刚性不够.

　(5)线圈及磁路的不平衡，及机械结构的不对称.

　(6)各部分配合松动。

　(7)线圈本身的位移。

　(8)转子偏心或动平衡不好。

　(9)轴承预紧力不合适。

　除此之外，还要考虑以下原因:

　(1)与安装机械和负载系统的共振。

　(2)传动系统(齿轮啮合的不平衡等)。

静口轴承以其高的回转精度、钢性好、承载力高、无磨损、耐用度高。下面是静口轴承在维修过程中探索和尝试取得的几点经验。小孔节流器：将内部节流改为外部节流，并加装压力表即时显示上下腔压力。使维修保养方便，特别是可以很容易地定期清洗，这是内部节流器无法比拟的。节流比。节流比β的理论值是1.2～1.5之间，而根据多年的经验以1.25为佳。这样在维修中，需要对主轴的几何精度、前后轴瓦的几何精度、同轴度、圆度及锥度进行严格控制，以便保证β值。

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。
