步进电动机失步原因分析及解决办法

电机属于一种控制电机，它是在一般旋转电机理论的基础上发展起来的具有特殊用途的电机，它主要是作信号的传递和转换，对其要求主要是运行的可靠性及快速反应的高精度。步进电机与交、直流伺服电机相比，在低速运行时有较大噪声和振动，在过载或高转速运行时会产生失步现象。利用步进电机控制机床的进给运动，限制了数控机床的精度和可靠性。步进电动机经常被用于精确定位的场合，因而保证步进电机不发生失步至关重要。电动机失步会影响数控系统的稳定性和控制精度，造成数控机床加工精度下降。分析了造成其失步的种种原因，有针对性地采取各项措施，克服失步带来的影响。

Analysis and solutions of out-of-step cause for stepper motor

The stepper motor is a kind of control motor with special purpose which is developed on the basis of general rotating motor theory.It mainly makes the signal transmission and convertion,so the running reliability and high accuracy of rapid response must be ensured.To compare with the stepper motor and AC-DC servo motor,it may cause big noise and vibration in low speed running,and arouse out-of-step phenomenon while in overload or high speed runnnig.To control the feed motion of machine tool by using stepper...
