In the present work we studied the possibilities of operating Switched Reluctance Motor (SRM) in regime of flux-weakening. The influence of control and geometrical parameters has been investigated and is presented for a 4 Kw machine of the type OULTON TM 8/6. We studied especially the effect of the rotor pole arc (βr) on the zone of flux-weakening. A purpose-built rotor with a different βr° fabricated in a framework of collaboration with two Tunisian companies has allowed validation of the numerical results.
