摘要
本文介绍一种在机床的数控改造和配套中按运动关系和应用虚功原理选配步进电机转矩的方法.根据笔者的经验,当预选的步进电机实际额定动态输出转矩是理论核算所要求的转矩值的1.5倍左右时到该步进电机在该数控系统中是适用的.
This paper introduces the method to match stepmotor torque according to virtual work principle in the NC reformation of old machine tools or in the NC design of new machine tools. According to author's experience this stepmotor is applicable to the NC System when the practical rated dynamic output torque is about 1. 5 times of that required for theoretical calculation. This method is simple and practical, and of little error in calculating.
