五相混合式步进电动机PWM调频调压驱动

Frequency/Voltage Modulated Drive of Five-Phase Hybrid Stepping Motor

提出一种步进电动机调频调压驱动的技术方案，讨论五相混合式步进电动机的调频调压规律，给出一种简明的设计方法，实测ＰＷＭ（脉宽调制）调频调压驱动系统的矩频特性。

A technical plan on the frequency/voltage modulated drive of stepping motor is presented. The author discusses the regular pattern of the frequency modulation and voltage modulation of the five-phase hybrid stepping motor; and gives a concise design method;and measures actually the torque and frequency characteristics of frequency/voltage drive.
