Induction machine modelling using permeance network for vector control drive applications.

In order to obtain a good compromise accuracy/computation time, we use permeance network method to solve the magnetic equations of an electromagnetic system. This method is explained in the first part of the paper: the network elements are calculated from finite element method, and then, the saturation is considered with Bur depending permeances. As for the electric and mechanic coupling, they are represented with the bond-graph method which the main principles are remained. In the second part, the method is applied to a squirrel cage induction machine. The results are discussed and accounting for the low computation time of the method, it is used to study the vector controlled induction machine behaviour.
