Axial airgap dynamoelectric machine

Claim 1

A BRUSHLESS DYNAMOELECTRIC MACHINE COMPRISING: A WINDING-FREE ROTOR HAVING A PAIR OF DISCS EACH WITH AN AXIS OF ROTATION AND PROVIDED WITH A FACE CONTAINING MAGNETIC MATERIAL LYING IN A PLANE SUBSTANTIALLY PERPENDICULAR TO THE AXIS OF ROTATION, SAID MAGNETIC MATERIAL EXTENDING INCOMPLETELY, BUT TO A SUBSTANTIAL EXTENT, AROUND THE AXIS OF ROTATION, A STATIONARY ARMATURE LOCATED ADJACENT AND JUXTAPOSED TO THE FACE OF EACH DISC, THE TWO DISCS BEING LOCATED BETWEEN THE TWO ARMATURES, EACH ARMATURE HAVING A CORE OF MAGNETIC MATERIAL EXTENDING CONCENTRICALLY AND COMPLETELY AROUND THE AXIS OF ROTATION AND HAVING AN ARMATURE WINDING PROVIDED WITH MEANS FOR CONNECTION WITH EQUIPMENT EXTERNAL OF THE MACHINE AND HAVING A FACE ALSO SUBSTANTIALLY PERPENDICULAR TO SAID AXIS OF ROTATION AND JUXTAPOSED TO SAID DISC FACE TO WHICH IT IS ADJACENT, WITH AN AXIAL AIR GAP BETWEEN THE ARMATURE FACE AND THE ADJACENT DISC FACE, STATIONARY MEANS COMPRISING MAGNETIC MATERIAL FORMING PARTS OF A PAIR OF CLOSED PATHS FOR MAGNETIC FLUX, ONE OF SAID PATHS PASSING THROUGH THE MAGNETIC MATERIAL OF ONE OF THE ROTOR DISCS AND ITS RESPECTIVE ARMATURE CORE AND THE OTHER PATH PASSING THROUGH THE MAGNETIC MATERIAL OF THE OTHER OF SAID ROTOR DISCS AND THE OTHER OF SAID ARMATURE CORES, AND A FIELD WINDING MEANS MAGNETICALLY RELATED TO SAID STATIONARY MEANS, WHEREBY WHEN SAID FIELD WINDING MEANS IS ENERGIZED MAGNETIC FLUX IS CREATED THROUGH SAID PATHS AND THE FLUX BETWEEN THE DISCS AND THE RESPECTIVE ARMATURES ACROSS THE RESPECTIVE AIR GAPS ROTATES WITH ROTATION OF THE ROTOR AND THEREBY CUTS SAID ARMATURE WINDINGS.
