A rotor 30 for a synchronous reluctance machine wherein a torque ripple behaviour of the machine is optimized by altering the geometry of insulating barriers 4 of the rotor 30. A q-axis pitch angle 12 is used as a design variable instead of setting its value equal to the rest of the rotor slot pitches or binding its value to the stator slot pitch. The resulting rotor 30 has a non-regular slot pitch across the q-axis and substantially regular slot pitch otherwise. Synchronous reluctance machines that employ rotor discs 1 and rotor assemblies in accordance with the present invention may exhibit low torque ripple without sacrificing high torque values. |
