Claim:
1. A double-rotor switched reluctance machine comprising: a stator, a first rotor, and a second rotor; the stator and the first rotor configured to operate as a first electric machine having an output torque profile that, for a first average output torque, fluctuates periodically between a first maximum instantaneous torque and a first minimum instantaneous torque as the first rotor rotates relative to the stator; the stator and the second rotor configured to operate as a second electric machine having an output torque profile that, for a second average output torque, fluctuates periodically between a second maximum instantaneous torque and a second minimum instantaneous torque as the second rotor rotates relative to the stator; the double-rotor switched reluctance machine configured so that when the first and second electric machines are operated at a common electrical frequency, the first and second maximum instantaneous torques are temporally offset, thereby reducing an overall torque ripple of the double-rotor switched reluctance machine.
