In the isolated stator sections 6/8 SRMs, wide stator teeth produce high flux, yet not all of this flux generates output torque. For proper design of the 6/8 SRM, the rotor teeth widths are less than the stator teeth widths, which means that not all the flux in the stator transfers to the rotor. In this study, the stator teeth are tapered to optimise the stator flux transfer from the stator to the rotor in order to increase the output torque. A comparison between the torque of the SRM with and without tapered stator teeth is presented.
