An axial flux machine comprises: a soft magnetic composite stator extension positioned in parallel with a rotor disk and having slots; soft magnetic composite pole pieces attached to the stator extension and facing a permanent magnet on the rotor disk, each comprising a protrusion situated within a respective one of the slots, each protrusion shaped so as to facilitate orientation of the respective pole piece with respect to the stator extension; electrical coils, each wrapped around a respective one of the pole pieces. In another embodiment the soft magnetic composite pole pieces each comprise a base portion around with the electrical coils are wound and a trapezoidal shield portion a plurality of heights with a first height in a first region being longer than a second height in a second region, the second region being closer to a pole-to-pole gap than the first region.
An axial flux machine comprising:
An axial flux machine stator comprising:
An axial flux machine comprising:
An axial flux machine stator comprising:
An axial flux machine stator pole piece comprising:
A method of fabricating an axial flux machine stator comprising attaching soft magnetic composite pole pieces to a soft magnetic composite stator extension by situating protrusions of the pole pieces within respective slots of the stator extension, each protrusion shaped so as to facilitate orientation of the respective pole piece with respect to the stator extension.
