【摘要】 先用步进电机的等效电路列出输入电路方程、输出机械方程,以及联系输入与输出之间的机电方程,接着用不同形状的三相电按是否细分去激励一已知参数的步进电机,从而获得该步进电机的动态特性,最后从中选出最佳激励方式。更多还原

【Abstract】 Based on the dummy input circuit of a stepping motor, the input circuit equation, output mechanical equation and the elcctromcchanica equation that connects the input and output of the motor are derived. A stepping motor with known parameters Is excited by finely-divided or not finely divided 3-phase AC voltages with different shapes, and then the dynamic property of the motor is obtained. Finally the optimal driving method is found.更多还原
