Abstract :
This paper investigates the effect of various rotor structures on the torque production capability of DC excited flux-switching motors. In these machines two set of windings, excited with DC and three-phase AC currents, are placed within the stator and the rotor structure should ensure that the applicable magnetic circuit is present to achieve both a high and smooth torque. As such, the rotor structure is an important factor that affects the performance of DC excited flux-switching motors. Results show that it is possible to increase the mean torque by varying the rotor tooth width or decreasing the torque ripple value by shaping the rotor tooth tip.
