永磁同步电动机驱动器的设计与实现
永磁同步电机是由永磁体励磁产生同步旋转磁场的同步电机,永磁体作为转子产生旋转磁场,三相定子绕组在旋转磁场作用下通过电枢反应,感应三相对称电流。此时转子动能转化为电能,永磁同步电机作发电机(generator)用;此外,当定子侧通入三相对称电流,由于三相定子在空间位置上相差120,所以三相定子电流在空间中产生旋转磁场,转子旋转磁场中受到电磁力作用运动,此时电能转化为动能,永磁同步电机作电动机(motor)用。![](https://public.fangzhenxiu.com/fixComment/commentContent/imgs/1686042743992_ag66w1.jpg?imageView2/0)
