摘要
反应式步进电动机是经济型数控机床的关键执行元件。文中以普遍使用的三相和五相反应式步进电动机为例,介绍它们在低频共振时的不同特点,给出了输出力矩下降幅度的计算公式,计算值与实测结果较为接近。
Reaction stepping motor is a key excute component of economic NC machine tool.It introduces the various characteristics in the low frequency resonance,by example with widely used three-phase and five- phase reaction stepping motors,and puts out calculation formula of torque reduction amplitude,and the calculating value is approximate to the test results.
