摘要
对隐极同步电动机恒磁变载时的圆图分Ef>U、Ef=U和Ef<U三种情形进行了详尽的研究 。
This paper makes a detailed study of circular diagrams for non-salient synchronous motors at constant magnetic field and variable load from three conditions of E_f>U, E_f=U, and E_f<U and deduces the feature of power factor of motor under different exciting conditions on the basis of this.
