Abstract:
A reluctance electric motor comprising: a substantially flat circular stator with a plurality of stator poles; and a substantially flat circular rotor having a plurality of rotor poles, the rotor being rotatably mounted relative to the stator and coaxial therewith, wherein the rotor further includes an amorphous ferromagnetic material having a ribbon structure as formed, the ribbon structure having a face and a side, the face having a width and the side having a thickness, the width of the face being greater than the thickness of the side, the face having the plurality of rotor poles formed therein, the rotor being rotatable mounted for rotation about an axis and is axially spaced from the stator, the rotor further being mounted on a bearing assembly defining a rotational axis; wherein the rotor has a central hole therein, and wherein the bearing assembly has a spherical bearing surface with a first diameter greater than a second diameter of the central hole for supporting and centering the rotor relative to the rotational axis when the central hole in the rotor is placed on the spherical bearing surface.
