简单来说当步进电机需要转动时控制系统会发送一系列脉冲信号给步进电机每个脉冲信号对应步进电机转动的一个步进角度。通过控制脉冲信号的频率和数量可以精确地控制步进电机的转动从而实现精准的位置控制和运动控制。
步进电机的相数是干嘛的比如两相是啥意思 步进电机的相数指的是步进电机的驱动方式中使用的线圈数量。常见的步进电机有两相、三相、四相和五相等不同的相数。
在两相步进电机中驱动方式包含两个线圈也称为相每个线圈独立控制一个电机极性。两相步进电机通过交替激活这两个线圈来实现转动。具体来说当一个线圈通电时它会产生一个磁场将电机转子吸引到对应位置当另一个线圈通电时前一个线圈的磁场会减弱电机转子会被吸引到新的位置。通过交替激活两个线圈可以实现步进电机的转动。
两相步进电机相对简单结构紧凑成本较低广泛应用于一些低要求的应用领域。然而由于只有两个线圈步进角度较大精度相对较低。
其他相数的步进电机如三相、四相和五相步进电机通过增加线圈的数量来提高步进角度的精度。随着相数的增加步进电机的转动变得更加平滑和精确但同时也增加了电机结构的复杂性和成本。
实物图 上位机Qt软件图
思路就是stm32一直给步进电机发脉冲然后通过驱动器驱动步进电机转动这个项目多了一个qt发送串口消息给stm32stm32接收对应的命令然后执行不同的函数但是这样无法实现步进电机的反馈无法实现限位回零等功能。 不过目前可以实现步进电机转动度数的控制因为实物没负载也没测试有没有丢步的现象还能实现正反转 stm32主要代码 Motor.h:
