This paper presents a method of predicting the steady-state performance of a new hybrid-excitation synchronous machine (HESM) theoretically. The field pole of this HESM is axially divided into two parts; one is an excitation part and the other a permanent-magnet (PM) part. A nonlinear equivalent circuit, which can include the saliency of the rotor and the magnetic saturation due to iron core, is derived. Based on this equivalent circuit, the steady-state performance of the HESM is calculated, and the results are confirmed through experiments.
