引进磁极位置检测元件的同步电动机其实是被解体的直流电动机中的电机本体,而磁极位置检测元件则是电刷及其刷座的衍生产物. 在他控式变频器 同步电动机系统中介入磁极位置检测元件即呈直流电动机运行性能,说明电动机的运行机制已发生改变,自控变频的"同步电动机"系统其实是广义的直流电动机. 按此认识,新型电动机系统的出现不会冲击传统的同步电机理论,关键是需更新对直流电动机的认识.从电流相位自控、电枢磁动势分析、电机本体的数学模型及电磁转矩控制方式等几方面阐明了由静止变频器与电机本体组成的广义直流电动机的基本作用原理.

A synchronous motor imported a position sensor becomes the motor body coming from disintegrated DC motor. The position sensor was an element within the motor body derived from brushes with their sets. A position sensor intervened into a converter-synchronous motor system made the motor system showed the performance of DC motor. This fact revealed that the running mechanism of the motor was changed. The synchronous motor system with self-controlled variable frequency would be transformed into the generalized DC motor. According to this viewpoint, it did not come into conflict with the classical theory of the synchronous motor. But we must renew our knowledge about DC motor. The basic operational principle of the generalized DC motor was explained.
