数控机床开环系统中常使用步进电动机驱动系统来驱动各运动轴工作。步进电机是利用电磁铁的作用原理,将脉冲信号转换为线位移或角位移的电机。每来一个电脉冲,步进电机转动一定角度,带动机械移动一小段距离。完全符合经济型数控机床的工作要求,在数控机床中应用很多。结合在工作实际中步进电动机驱动系统的常见故障进行分析,深入浅出介绍故障的分析方法及处理方法,具有指导意义。
Open-loop CNC system often use stepping motor drive system to drive the work of all axes. Stepper motor is the use of the principle of electromagnetism, the pulse signal is converted to linear displacement or angular displacement of the motor. Every time an electric pulse, the stepping motor rotates a certain angle, the mechanical movement of a short distance. In full compliance with the economic requirements of CNC machine tools, CNC machine tools used in many. Combined with the common faults of the stepper motor drive system in practical work, the analysis method and the method of dealing with faults are introduced in depth, which is of guiding significance.
