摘　　要：在步进电机细分驱动系统中,由于步进电机绕组电流与磁场幅值之间的非线性关系,以及步进电机转子的磁滞效应等因素,细分后得不到均匀的步距角,因此必须对细分电流的大小进行修正.讨论了修正的方法,并给出了修正后的实验数据.In the system of subdivided driving of stepping motor, because of the nonlinearity between winding current and the amplitude of magnetic field, and the hysteresis effect of stepping motors and so on, the even microstep angles can not be achieved. Therefore, the winding current must be revised. The revising method is talked about, and the microstep angles after revising are presented.
