Ultra-high speed permanent magnet axial gap alternator with multiple stators

An ultra-high speed, permanent magnet, axial-gap alternator for supplying at least two loads, which comprises:

• a rotatable shaft having an axis;
• means for rotating said shaft around said axis at a selected speed;
• a disk-type rotor member fixedly attached to said shaft so as to rotate with said shaft, said rotor member having first and further parallel surfaces perpendicular to said axis, said rotor member fabricated from laminated disk-type layers having
• a. a central disk-shaped layer of a magnetic material extending from proximate said shaft to a peripheral edge, said central layer terminating at said peripheral edge in a rim that extends from said first to said further surfaces of said rotor member,
• b. a first layer of a non-magnetic material joined to a first surface of said central layer, said first layer of non-magnetic material defining said first surface of said rotor member,
• c. a second layer of non-magnetic material joined to a second surface of said central layer, said second layer of non-magnetic material defining said second surface of said rotor member,
• d. a first set of an equal number of cylindrically-shaped magnets positioned within said first layer of non-magnetic material and arranged at a first common radius from said shaft, said magnets of said first set extending substantially from said first surface of said rotor member to said central layer of said rotor member and oriented to have alternating polarities, and
• e. a second set of an equal number of cylindrically-shaped magnets positioned within said second layer of non-magnetic material and arranged at a second common radius from said shaft, said magnets of said second set extending substantially from said further surface of said rotor member to said central layer of said rotor and oriented to have alternating polarities opposite said polarities of said first set of magnets across said central layer of said rotor member;
• a first disk-type stator member positioned at close proximity to said first surface of said rotor member, said first stator member having a surface, facing said first surface of said rotor member, provided with equally-spaced radially extending slots, said slots containing winding members each electrically connected to a first output cable for said first stator member to connect said first stator member to a first load;
• and
• a second disk-type stator member positioned at close proximity to said further surface of said rotor member, said second stator member having a surface, facing said further surface of said rotor, provided with equally-spaced radially extending slots, said slots containing winding members each electrically connected to an output cable for said second stator member to connect said second stator member to a second load.
