Abstract 1. THE METHOD OF FABRICATING AN INTEGRAL ROTOR ASSEMBLY FOR A DYNAMOELECTRIC MACHINE, SAID ROTOR ASSEMBLY INCLUDING A ROTOR AND A FORCE-TRANSMITTING ELEMENT, SAID ASSEMBLY BEING MOLDED OF A MIXTURE OF THERMOPLASTIC AND PERMANENTLY MAGNETIZABLE PARTICLES, SAID ROTOR HAVING A MAGNETIZED PERIPHERAL PORTION, SAID ELEMENT BEING SPACED RADIALLY INWARDLY FROM SAID PERIPHERAL PORTION AND NOT BEING MAGNETIZED; COMPRISING THE STEPS OF MIXING PREDETERMINED QUANTITIES OF THERMOPLASTIC AND MAGNETIZABLE PARTICLES, INJECTION MOLDING SAID ASSEMBLY OF SAID MIXTURE, SAID MOLDING STEP INCLUDING THE MELTING OF SAID THERMOPLSTIC PERMITTING IT TO COOL AND THEREBY SOLIDIFY, MAGNETICALLY ORIENTING SAID PARTICLES BY PASSING FLUX LINES RADIALLY THROUGH SAID PERIPHERAL PORTION DURING THE PERIOD WHEN SAID THERMOPLASTIC IS MOLTEN, SHUNTING THE FLUX LINES AWAY FROM SAID FORCE-TRANSMITTING ELEMENT, AND CAUSING SAID THERMOPLASTIC TO SOLIDIFY THEREBY SECURING SAID PARTICLES IN SAID PERIPHERAL PORTION IN MAGNETIICALLY ORIENTED POSITION.
THE METHOD OF FABRICATING AN INTEGRAL ROTOR ASSEMBLY FOR A DYNAMOELECTRIC MACHINE, SAID ROTOR ASSEMBLY INCLUDING A ROTOR AND A FORCE-TRANSMITTING ELEMENT, SAID ASSEMBLY BEING MOLDED OF A MIXTURE OF THERMOPLASTIC AND PERMANENTLY MAGNETIZABLE PARTICLES, SAID ROTOR HAVING A MAGNETIZED PERIPHERAL PORTION, SAID ELEMENT BEING SPACED RADIALLY INWARDLY FROM SAID PERIPHERAL PORTION AND NOT BEING MAGNETIZED; COMPRISING THE STEPS OF MIXING PREDETERMINED QUANTITIES OF THERMOPLASTIC AND MAGNETIZABLE PARTICLES, INJECTION MOLDING SAID ASSEMBLY OF SAID MIXTURE, SAID MOLDING STEP INCLUDING THE MELTING OF SAID THERMOPLSTIC PERMITTING IT TO COOL AND THEREBY SOLIDIFY, MAGNETICALLY ORIENTING SAID PARTICLES BY PASSING FLUX LINES RADIALLY THROUGH SAID PERIPHERAL PORTION DURING THE PERIOD WHEN SAID THERMOPLASTIC IS MOLTEN, SHUNTING THE FLUX LINES AWAY FROM SAID FORCE-TRANSMITTING ELEMENT, AND CAUSING SAID THERMOPLASTIC TO SOLIDIFY THEREBY SECURING SAID PARTICLES IN SAID PERIPHERAL PORTION IN MAGNETIICALLY ORIENTED POSITION.
