The double stator switched reluctance motor is a derivative of the traditional SRM, using a segmented rotor and two coaxial stators to increase flux density in the machine and improve torque density. Switched reluctance motors suffer from a propensity to high torque ripple, and the DSSRM inherits this shortcoming. This work investigates a method to reduce torque ripple in the DSSRM by strategically misaligning the two stators, which are aligned in the nominal design. The methods for simulation and data postprocessing will be discussed, as well as a discussion of the mechanism for reduced torque ripple.
