进电机之两相双极性步进电机仿真

两相双极性步进电机

　　有幸能从报废的机器的光驱中拆除几个电机，大概是像下方图片中那样的。可是这个电机只有四根外接的引脚，以前对不只电机不是很懂，这两天经过查阅资料，了解到这个电机被称为两相双极性步进电机。git

　　在此大概叙述下两相双极性电机的工做原理。以下图所示，步进电机只有两相（即两组定子），双极性表明两个定子缠绕的线圈能够两个方向通电。oop

　　简单用图片表示下90度两相双极性步进电机转一圈的过程。1表示相1正向通电，1~表示相1方向通电。ui

　　上面只是简单叙述了下两相双极性步进电机的工做原理，下面进入正题，使用proteus进行仿真Arduino来控制电机。spa

　　仿真：使用L298(U3)驱动四线两相双极性步进电机。code

　　代码：MotorTwo为两相双极性电机驱动。blog
