交流电机旋转磁场CAI课件的开发

Development of Pedagogical Software for Rotating Magnetic Field in AC Machine

电机学课程教学中涉及到三种典型磁场:单相脉振磁场、圆形旋转磁场和椭圆形旋转磁场。旋转磁场CAI课件,把旋转磁场特点及形成过程以动态直观形式表现出来,展示了单相绕组脉振磁势和三相绕组合成旋转磁势的时空关系。

There are three kinds of typical magnetic fields concerned in the pedagogy of electrical machines curriculum, i.e. the pulsating magnetic field, the round rotating magnetic field and the elliptical rotating field. The pedagogical software of rotating magnetic field designed by authors can manifest the feature of various magnetic fields and their formative process by means of dynamic and perceivable manners. It shows the relationship between time and space for the single-phase pulsating magnetic field and the rotating magnetic field of three-phase winding.
