摘　　要：归纳出旋转磁场的三个规律:位置定律、转速定律、转向定律。引入“空轴”以取代“相轴”,指出时轴和空轴的不同功能:时轴用于投影,空轴用于定位。空间矢量没有“相”的概念,只有“位”的概念。This paper summarizes three laws of rotating magnetic field,i.e.position law,rotating speed law and rotating direction law.“Space axis”is introduced to take the place of“phase axis”.It is pointed out that time axis and space axis have different functions:time axis is used for projection,while space axis is used for location.Space vectors have no conception with“phase”,but have conception with“position”.

关 键 词：旋转磁势 旋转磁密 旋转磁场 相量 空间矢量 时空矢量图
