1. An electric machine comprising:

  • a housing;

    a pair of stators which are fixedly disposed within said housing and which each include a core and a winding;

    a first rotor which is rotatably mounted to a shaft and which is disposed between said pair of stators, said rotor having a first plurality of permanent magnets, a first plurality of consequent poles, a second plurality of permanent magnets which cooperate with said first plurality of permanent magnets to selectively generate a first magnetic flux, and a second plurality of consequent poles which cooperate with said first plurality of consequent poles to selectively generate a second magnetic flux; and

    a field coil, said field coil being fixedly and circumferentially mounted within said housing; and

    a controller which is operatively coupled to said field coil and which selectively provides power to said field coil, thereby causing said field coil to selectively vary said second magnetic flux.
