CLAW-POLE ALTERNATOR MODELING USING PERME ANCE NETWORK COUPLED WITH ELECTRICAL CIRCUIT

We propose in this paper, a modeling and simulation method of a three dimensionnal (3D) machine by electric-magnetic coupled network, based on the permeance network. The proposed approach allows us to easily ta ke into account non linearities such as saturation and rotor movement, with a very weak simulation time. We present the modeling of the auto motive alternator, that is an axial flux machine called modified Lunde ll alternator. Different results of computations of two claw-pole alte rnators at no-load and at load are presented and compared with experim ental results, showing that the proposed method is a satisfactory comp romise between precision and simulation time for dynamic modeling of g eometricaly complex electrical devices.
