Modeling of a claw-pole alternator using permeance network coupled with electric circuits

We propose in this paper, a modeling and simulation method of electrical machines by electric-magnetic coupled network, based on the Bond-Graph models and permeance network. The proposed approach allows us to easily take into account nonlinearities such as saturation and simple hysteresis effects, and to obtain forces applied on the teeth, with a simulation time very weak compared to the finite element method. This method is very interesting for three dimensional studies of typical machines, as for example: a claw-pole alternator
