功率步进电动机驱动的几个特殊问题

THE SEVERAL SPECIAL PROBLEMS OF POWER STEP MOTORS DRIVING SYSTEMS

高频波段扩展、低频波段运行平稳、细分定位精密、负荷突跳频率高、电路优化是当前步进电动机驱动的几个特殊问题。研究功率步进电动机驱动系统的发展,提出解决这些问题的T比例变换原理和方法,得到新的驱动系统。

Expansion in high frequency, stationary operation in low frequency, ministep acculatly fixed position, high started frequency, and optimized circuit are important special problems in the study of power step motors driving at present. In the paper new principles and methods for solving these problems have been advanced, and some new power step motors driving systems are set up, with the study of developmental process of power step motors driving.
