2相电机程序移植到3相电机！高手们出来论剑啦！！！

大神们，2相电机相电流相差90度，那数组const u16 SinDataA与const u16 SinDataC 里这些点所描绘的sin曲线是不是就是相差90度啊？我大概描了一下，好像是相差90度，不知道是不是巧合呢。
于是我就寻思着把那两个数组里面的值的位置移动了一下，使那些点所描绘的曲线相差120度，再用原来的2相驱动程序做，一直让电机转会有点卡而且有点吵，但是单步走的时候效果还是不错的，希望大神们来看看是啥问题。
const u16 SinDataA = //128*4

2相电机相电流相差90度，3相相差120度没错，但表数据具体看硬件。

sunrosewang 发表于 2016-6-14 21:20:41

你用的是什么电机，导步或者同步三相电机吗，还是无刷电机？三相电机可以用svpwm发波，算法也不是很难的。

是用spwm做的，大神有做过？我觉得好难，无从下手

还不是一样的查表么？只是相位差不同而已

明显有问题吧，你对比一下两相的曲线。表数据是否相同要看硬件的！
