A permanent magnets synchronous machine electromagnetic design is presented in this paper. The machine is characterised by a concentrated windings stator and focusing principle ferrite permanent magnets rotor. First, an analytic study is lead to determine the main influent parameters. A finite element analysis is then achieved in order to study more precisely the geometric parameters impact on the...
In this paper the suitability of a class of electric machines for vehicle traction application is discussed. These machines, known as hybrid excitation synchronous machines, combine a permanent magnet excitation with wound field excitation. The goal behind the principle of hybrid excitation is to combine advantages of PM excited machines and wound field synchronous machines. It is shown that these...
This paper presents a description and operating principle of different hybrid excitation synchronous machines. Four prototype machines of different power rating (3 kW and 15 kW) have been studied. These machines combine two flux sources: permanent magnets, located in the rotor, and field coils, located in the stator. Thanks to this particular configuration the air gap flux can be easily controlled,...
