  • Technique of fixing a permanent magnet in rotor
    Patent number: 8844119
    Abstract: A technique for fixing permanent magnets of a drive motor rotor for a vehicle may include inserting permanent magnets into a plurality of permanent magnet insertion holes that are formed at a predetermined distance from each other in a circumferential direction of a rotor core, applying magnetic force to the rotor core with a magnetic force generator, such that the magnetic force is formed in an axial or a radial direction of the rotor core to instantly fix the position of the permanent magnets, and adding a fixation material to the permanent magnet insertion holes to fix the permanent magnets.
    Type: Grant
    Filed: December 9, 2011
    Date of Patent: September 30, 2014
    Assignees: Hyundai Motor Company, Kia Motors Corporation

  • FIXING A PERMANENT MAGNET IN A DRIVING MOTOR ROTOR
    Publication number: 20120326549
    Abstract: A method of fixing a permanent magnet in a rotor of a driving motor, e.g., for a vehicle, includes inserting the permanent magnet into a core of the rotor and fixing the permanent magnet by supplying resin to the permanent magnet, wherein a coefficient of thermal expansion of the resin is substantially equal to that of the rotor core.
