　　其实只说电流影响力矩，电压影响速度是不正确的，无论电流还是电压的变化都将改变步进电机的矩频特性，改变电压同样改变步进电机的力矩，改变电流同样改变步进电机的高速性能。

　　伊诗图电气建议需要值得注意的是：

　　，电压或者增大电流，都会增加步进电机发热，步进电机温度过高会产生热退磁，所以尽量选择有一定余量的电机规格；第二，在电机力矩足够的情况下，我们尽量把电流设置到比额定电流略小一点的档位，这样可以延长步进电机和驱动器的使用寿命；第三，一款额定电压为80V的驱动器，我们尽量用到70V左右，额定电压AC18-80V，但是民用电和工业用电都存在一定的电压波动范围，机器上电和断电的瞬间峰值电流电压会很高，所以留一些余量将大大降低返修率。一些小品牌的步进电机驱动器会给使用100V电容的驱动器标称电压范围C24-0V，如果用户真的按80V供电，那是有点危险的。

何挺建议投资者重点关注包钢稀土，目前这2只个股都分别站上了年线，走势上呈震荡盘升格局，可在其调整回踩年线时适当关注。行业整合预期催生板块强势上行，但部长同时表示，整合方案目前并没有时间表。李瑜分析表示，稀土板块在本轮行情中的累计涨幅已经较大，从估值的角度讲，安全边际已不足够大，尽管短期仍有可能惯性冲高，但投资人宜留意该板块的震荡风险。从该板块个股操作的角度讲，可以关注目前涨幅相对较小的中色股份，以及铝业、发展等股票。

因为实际上模型或产品本身是不够光滑或，所以要复制的产品或模型如果没有经过打磨或抛光，再好的做的模具也会不美观、不够光滑。还有一种情况就是，在打脱模剂的时候，没有涂刷均匀也会造成模具不光滑。模具的奇妙用途您知道吗？模具主要用于玩具礼品行业，工艺礼品行业，家具装饰装潢行业，人物复制，建筑装饰装潢行业，树脂工艺品行业，不饱和树脂工艺品行业，蜡烛工艺？塑胶玩具行业，？礼品文具行业？，石膏工艺礼品行业，？模具制造行业，？波丽工业品？，仿真动植物雕塑，佛雕工艺品等多种行业的产品复制及模具制作。
