A permanent magnet machine is provided including a stator and a rotor, the rotor being adapted to rotate relative to the stator, the rotor including a plurality of permanent magnets separated in the circumferential direction from each other by radially extending rotor pole pieces for concentrating the magnetic flux from the permanent magnets, the stator having a structure that defines radial limits of an air gap between the stator and the rotor for communicating magnetic flux between the stator and the rotor, wherein at least some of the permanent magnets extend radially outside the radial limits of the air gap as defined by the stator structure.
