Design and optimization of a permanent magnet axial flux wheel motors for electric vehicle
Axial flux motor with two flat PM rotors and one coreless stator is designed and manufactured for the propulsion of an electric vehicle supplied by a Fuel cell. The originality of the architecture consists in the stator winding which is manufactured as a printed circuit with thick copper lamination. The second originality in this paper consists on the use of the duality between magnetic vector potential and flux density in a magneto-static problem. It allows using standard 2D finite element code for the computation of the fluxes and electromotive forces of an axial flux PM motor. The model is then used to optimize the winding topology in order to increase the efficiency of the propulsion system of electric vehicle powered by a fuel cell.
