Axial flux machine design for hybrid traction applications

Now a days, hybrid traction seam s to be one of the best ways in order to reduce fuel consumption for vehicles. It consists of associating an electric motor next to the classical thermal machine. Bi such an embedded system , the efficiency and the torque per unit mass are very important. So it seem s to be a good idea to use the permanent magnet synchronous machine, which is recognized for satisfying these two objectives. Since the allocated volume is rather flat, axial flux topologies are interesting [1] .This papers goal is to propose an optimal first design method for such structures, given the allocated volume and the machine requirements. Then we study the flux weakening capabilities of the machine, which is always an important point for traction applications.
