第一步:新建一个model,加入BLDC模型。如下图所示,添加一个1处所示的Permanent Magnet Synchronous Machine。并且关键一步,将反电动势波形选择为梯形波,梯形波才是无刷直流电机,如果正弦波就是永磁同步电机了。因为我们只是需要电机转起来,不需要特地的设置电机参数,看一看就可以啦。 第二步:添加电机参数。因为这里不涉...
转子为永磁体(permanent magnet)。当定子线圈通上 ABC 三相交流电后,由于电磁效应带动转子转动,而转子转动的频率和 ABC 三相交流电的频率相同,所以叫同步电机(synchronous motor)。 和PMSM 非常相似的一种电机叫做 BLDC Motor(直流无刷电机,Brushless DC)。它们显著的区别在于反电动势(back EMF)的波形。BLDC 的反电...

如中部图所示,三相电流的上升经过了一段时间,由此导致速度信号产生波纹。但速度不是唯一受影响的信号;在转矩响应中也有波纹,如之前的底部图所示,因为电流和转矩成比例。此转矩波纹是 BLDC 电机梯形控制的主要缺点之一。借助更先进的磁场定向控制(通常用于驱动 PMSM 电机),可以克服梯形控制的一些缺点。
