Résumé : Some methods for considering skewed slots are briefly discussed. It is shown that for a rigorous modelling of skew and of the ensuing axial variation of saturation, a 2.5D multi-slice model is a viable alternative to a fully 3D model. The computational cost of time stepping such a FE model connected to an external electrical circuit using either a direct or an indirect coupling method is studied. The latter is applied to the simulation of a squirrel-cage induction motor, for which four different rotors (with unskewed or skewed slots and with open or closed slots) are available. A satisfactory agreement between measured and computed stator phase current waveforms has been obtained for both no-load and load.
