| Popis: | The switched reluctance motor (SRM) is of great interest in industrial applications due to its highly appreciated performances and especially for its open loop operating capacity. However, its model is highly nonlinear when taking into account magnetics saturation effects. In this paper, in order to increase the zones of acceleration of the SRM, a new shape of rotor is proposed in order to push the limits of operation towards the high frequencies. The finite element method (FEM) through the FEMM field calculation software was used in order to take into account the geometric structure and saturation phenomena of the magnetic circuit of the machine. Using some tools of chaos, the results obtained have been compared with other SRM structures such as conventional and attack-teeth structures. It appeared that the proposed hollow-teeth structure shows a good dynamic performance in open loop and allows a perfectly periodic dynamic response at high control frequencies. Indeed, the presence of small teeth on the rotor teeth increases the acceleration zones of the machine, which allows it to operate at high frequencies. |
