Patent Images

20. A PERMANENT MAGNET GENERATOR COMPRISING (A) A STATOR CORE OF ANNULAR LAMINATIONS WITH RADIAL TEETH AND SLOTS ON THEIR INTERNAL PERIPHERY;

(B) A THREE-PHASE WINDING DISTRIBUTED IN THE SLOTS OF SAID STATOR CORE;

(C) A ROTOR CONSISTING OF A PERMANENT MAGNET STRUCTURE WITH POLE PIECES AT THE ENDS OF THE PERMANENT MAGNET STRUCTURE, EACH POLE PIECE HAVING AN ARCUATE PERIPHERAL SURFACE AND A FLAT END SURFACE, THE PERIPHERAL SURFACES BEING SAPCED FROM THE STATOR CORE BY A NARROW AIR GAP DURING OPERATION;

(D) AN AUXILIARY STATOR CORE STRUCTURE CONSISTING OF A PLURALITY OF SUBSTANTIALLY C-SHAPED ELEMENTS POSITIONED ADJACENT THE PATH OF ROTATION OF THE POLE PIECES AND DISPOSED TO BE MAGNETICALLY COUPLED TO SAID POLE PIECES DURING THEIR ROTATION, AND (E) WINDINGS ON SAID AUXILIARY CORE ELEMENTS TO GENERAGE A ROTATING MAGNETIC FIELD.
