Abstract
Abstract THEREBETWEEN. THE JOURNAL AND SUPPORT STRUCTURE FOR THE ROTOR AND STATORS IS OF A CONFIGURATION TO PERMIT MAXIMUM ROTOR AND STATOR INTERFACE SURFACE ALIGNMENT AND TO PROVIDE MAXIMUM EFFICIENCY FROM THE DYNAMOELECTRIC MACHINE. A DYNAMOELECTEIC MACHINE HAVING COAXIAL INNER AND OUTER CYLINDRICAL STATORS AND A PAIR OF END STATORS WITH EACH STATOR BEING PROVIDED WITH A PLURALITY OF MAGNETIC FLUX PRODUCING PERMANENT MAGNETS. THE ROTOR IS A CYLINDRICAL CONFIGURATION AND IS DISPOSED IN THE MAGNET GAP BETWEEN THE INNER AND OUTER STATOR AND END STATORS COMPRISES A PLURALITY OF RADIALLY DISPOSED COILS, MAGNETIC CORES WITH WINDINGS AND INTERMEDIATE MAGNETIC CORES WITHOUT WINDINGS DISPOSED
