This paper deals with the performance analysis of a DC-excited dual-speed synchronous machine (DSSM) with salient poles equipped with a damper winding. The proposed DSSM can operate at two speeds when connected to the mains. The number of pole pairs can be adjusted while running by the special design of the stator and rotor windings, which can commute between p = 1 and p = 2 pole pairs (by adjusting simultaneously the stator and rotor coil connections). The presence of the damper winding is helpful for the machine to self-start when directly connected to the grid as a motor and to pass smoothly from one speed to the other. The 2D finite element computations used to estimate the machine transient regimes and to determine its specific characteristics were carried out using the professional software package Flux® dedicated to electromagnetic field analysis. The proposed machine was analyzed both as a motor and as a generator.
