Self-regulating brushless permanent magnet ac generator

Claim 1

A SELF REGULATING BRUSHLESS PERMANENT MAGNET ALTERNATING CURRENT GENERATOR COMPRISING A MAGNETICALLY CONDUCTIVE SHAFT, A PERMANENT MAGNET ROTOR MOUNTED ON THE SHAFT, A SLUG CONDUCTIVE TO MAGNETIC FLUX HAVING HALF AS MANY POLES AS THE ROTOR MOUNTED ON THE SHAFT ADJACENT TO THE ROTOR, A NONMAGNETIC SPACER MOUNTED ON THE SHAFT BETWEEN THE ROTOR AND THE SLUG TO ISOLATE THE ROTOR FROM THE SLUG, AN ANNULAR STATOR CONTAINING A WINDING, SAID STATOR BEING DISPOSED AROUND AND RADIALLY EQUIDISTANT FROM THE ROTOR AND THE SLUG, END BELLS CONDUCTIVE TO MAGNETIC FLUX ARRANGED AROUND THE ENDS OF THE SHAFT IN CONTACT WITH THE STATOR BUT SEPARATED FROM THE SHAFT BY AN AIR GAP, AND MEANS MOUNTED IN THE END BELL AND ELECTRICALLY CONNECTED TO THE STATOR WINDING FOR ENERGIZING THE SLUG AND CREATING A SEPARATE REGULATING FLUX PATH THROUGH THE SHAFT, STATOR, AND END BELL TO INDUCE A VOLTAGE IN THE STATOR WINDING WHICH CAN BE MADE TO OVER COMPOUND, LEVEL COMPOUND, OR UNDER COMPOUND THE INHERENT VOLTAGE INDUCED BY THE ROTOR FOR A SPECIFIED LOAD CURRENT.
