步进电机微步驱动系统

步进电机区别于其他电机的最大优点是其转动的角度与输入脉冲数成正比，其转速由脉冲信号频率决定，而且不会有积累误差。由于这些特点，步进电机在开回路控制中得到了广泛的应用。本文基于步进电机系统，设计了一种新型的高精度的步进电机微步驱动系统。通过发送简单的控制命令，就可以控制电机实现高精度的运动。

Subdivided Driving System of Stepper Motor

Stepper motor＇s optimum specialty is that its rotational angle is proportional to its number of input pulse. Its rotate speed depends on its frequency of pulse signal and it hasn＇t accumulated errors. Stepper motor has been widely used in open and loop circuit controlling for its specialty. This paper designs a new high-accurate subdivided driving system of stepper motor based on stepper motor system. We can control the motor＇s highaccurate motion through sending easy control command.
