摘要
提出了一种环形绕组盘式永磁电机弱磁控制新方法，该方法采用附加直流绕组产生定子附加磁通的手段降低定子铁心的导磁率μＦｅ，增加定子磁压降，达到削弱气隙主磁通的目的。采用文中提出的弱磁方法不会使气隙主磁通波形发生畸变，控制简单，弱磁效果明显。
A new field weakening control method of the torus PM machine is presented.A DC winding is added in stator slot for producing additional stator flux,decreasing stator core permeance μ Fe and incrensing stator core magnet voltuge,so that the air gap flux can be weakened.The field weakening control method proposed in this paper has many advantages such as simple control,not distorting air gap flux waveform and having obvious effect of field weakening.
