5 6)步进电机存在振荡和失步现象,必须对控制系统和机械负载采取相应措施。 7)一般步进电机的精度为步进角的3-5%,且不累积。 8)步进电机温度过高首先会使电机的磁性材料退磁,从而导致力矩下降乃至于失步,因此电机外表允许的温度应取决于不同电机磁性材料的退磁点;一般来讲,磁性材料的退磁点都在摄氏130度以上,有的甚至高达摄氏200度以上,所以步进电机外表温度在摄氏80-90度完全正常。 9)当步进电机转动时,电机各相绕组的电感将形成一个反向电动势;频率越高,反向电动势越大。在它的作用下,电机随频率(或速度)的增大而相电流减小,从而导致力矩下降。 10)步进电机有一个技术参数:空载启动频率,即步进电机在空载情况下能够正常启动的脉冲频率,如果脉冲频率高于该值,电机不能正常启动,可能发生丢步或堵转。在有负载的情况下,启动频率应更低。如果要使电机达到高速转动,脉冲频率应该有加速过程,即启动频率较低,然后按一定加速度升到所希望的高频(电机转速从低速升到高速)。 步进电动机以其显著的特点,在数字化制造时代发挥着重大的用途。伴随着不同的数字化技术的发展以及步进电机本身技术的提高,步进电机将会在更多的领域得到应用。

一般数控卧式加工中心安装在机加工车间,不仅环境温度变化大,使用条件差,而且各种机电设备多,致使电网波动大。安装加工中心的位置,需要电源电压有严格控制。电源电压波动必须在允许范围内,并且保持相对稳定。否则会影响加工中心数控系统的正常工作。数控卧式加工中心的环境温度低于3摄示度,相对温度小于8%。一般来说,数控电控箱内部设有排风扇或冷风机,以保持电子元件,特别是处理器工作温度恒定或温度差变化很小。

众所周知,稀土在各种材料中有诸多优异的性能,如:在金属材料中,能起到细化基体晶粒、强化基体组织、改善基体机械性能和力学性能,以及提高金属基体的耐腐蚀性能等。在热镀锌过程中,添加适当的稀土金属,不仅能使锌液的熔点降低,增加锌液的流动性,使热镀锌层薄而均匀,增加镀层表面光洁度,同时还大大增强了镀层的耐腐蚀性能和机械性能,延长镀层的防护时间[2~3]。我国是世界上稀土储量最为丰富的国家之一,大力深入的开展稀土热镀锌的技术研究和开发,具有十分重要的经济效益和社会效益。
