摘要
针对三相反应式步进电动机设计了一种经济实用的驱动器。该驱动器采用高、低压电源自动切换供电技术和恒流斩波驱动方式,降低了步进电动机的低频振荡,提高了步进电动机的高频力矩。采用VMOS管驱动电机,使得驱动电源稳定可靠。
An economical and practical driver for 3 - phase reaction stepping motor was designed in the paper. The driver adopted the technique of automatic power changing between high and low voltage and the driving mode of constant current cutting wave, so that the low - frequency vibration of the stepping motor was reduced and the high - frequency torque was increased. The driver was stable and reliable by using VMOS transistors to drive stepping motor.
