摘要
为了设计一款基于数字信号处理器和功率驱动芯片的两相混合式步进电机细分控制电路,通过分析两相步进电机运行特性及细分驱动原理,使用数字信号处理器计算细分电流数据和产生控制用脉宽调制波形,简化了系统构成。驱动器能明显提高步进电动机的运行精度,改善低频振荡的现象,可实现细分级别的任意设置,能根据不同应用场合使用不同细分数来驱动步进电机。
In order to design a circuit of micro-stepping drive for two-phase hybrid stepping motor based on Digital Signal Processing（DSP） and power-drive chip, by analyzing micro-stepping driving method of two-phase hybrid stepping motor, using DSP to calculate micro-stepping data of phase current, a practical and effective system can be set up. The driver can improve the r^nning precision and the low-frequency oscillation phenomenon of stepping motor. The micro-stepping level can be chosen arbitrarily, which makes the motor suitable for different applications.
