This paper presents a hybrid excitation synchronous machine which combines a permanent magnet excitation with a wound field one. With two sources of flux, this kind of machines is cited more and more frequently in vehicle application for easier control of flux. After a brief description of the structure, some methods will be presented to improve the performances of this machine. Simulation results have shown that the armature reaction has a magnetizing effect when it enters in a pole face and a demagnetizing effect when getting out from the same pole, which distorts the main field and to some extent deteriorates the performances of the machines. The methods we present here are based on the principle of armature reaction compensation which might be extended to many synchronous machines. And then, in the last section, a general optimization tool (numerical design of experiments and optimization) is used to maximize the impacts of these methods.
