摘　　要：本文提出了一种单片机控制的软硬件结合的正弦波细分的三相混合式步进电动机微步驱动系统 .系统采用电流跟踪控制方式 ,使混合式步进电机的各相电流接近正弦波 ,在电机内形成一个幅值基本不变的圆形旋转磁场 。It is presented in the paper that SIN subdivide microstep driving system with microprocessor controlled for three phase hybrid stepping motor synthesises both software and hardware. With the style of traced current, the method makes current in each phase similar to sine wave, so it establishes a round rotation magnetic field, which forms a constant torque. The operating performance of stepping motor is remarkably improved.
