摘　　要：在分析步进电机运行特性的基础上 ,讨论了步进电机运行时高速失步和低速波动的原因及其对策 ,研究了转换角和超前角在步进电机速度控制中的作用 ,采用改变光栅反馈脉冲当量角及延时调整转换角的方法进行速度的平稳调节 。The reasons of stepout in high speed and surge in low speed during stepping motor running and the corresponding countermeasures are discussed based on the analysis of the running property of stepping motor.The functions of lead angle and switch angle in speed control of the stepping motor are studied.The smooth adjustment for the speed is carried out through changing grating signal feedback pulse angle and delaying the adjustment of switch angle.A speed control scheme and the performing method are also given.

关 键 词：步进电机 光栅信号 速度控制
