Pangeun KIM has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11355979
    Abstract: A motor includes a stator and a rotor. The rotor includes: a plurality of rotor core segments arranged along a circumferential direction of the rotor on the inner side or the outer side of the stator and spaced apart from one another to define a plurality of permanent magnet arrangement slots between the plurality of rotor core segments, a plurality of permanent magnets inserted into the plurality of permanent magnet arrangement slots, respectively, a rotor frame that couples the plurality of rotor core segments and the plurality of permanent magnets to each to other, and an outer ring that is made of a non-magnetic material and that surrounds an outer end of the plurality of rotor core segments and an outer end of the plurality of permanent magnets. The plurality of rotor core segments and the plurality of permanent magnets are alternately arranged along the circumferential direction of the rotor.
    Type: Grant

  • Patent number: 11349360
    Abstract: A motor includes a stator and a rotor rotatably disposed at an inner side of the stator or an outer side of the stator. The rotor includes a rotor core block including a plurality of rotor core segments that are arranged along a circumferential direction of the rotor, where each of the rotor core segments includes a plurality of electrical steel sheets that are stacked on one another. The rotor further includes a plurality of permanent magnets disposed between the plurality of rotor core segments, where the plurality of rotor core segments and the plurality of permanent magnets are alternately arranged along the circumferential direction of the rotor. The plurality of electrical steel sheets include bridges that connect the plurality of rotor core segments to one another along the circumferential direction of the rotor.

  • Patent number: 11264851
    Abstract: A motor includes a stator and a rotor. The rotor includes: a plurality of rotor core segments arranged along a circumferential direction of the rotor on the inner side or the outer side of the stator and spaced apart from one another to define a plurality of permanent magnet arrangement slots between the plurality of rotor core segments; a plurality of permanent magnets inserted into the plurality of permanent magnet arrangement slots, respectively; a first frame that couples the plurality of rotor core segments to the plurality of permanent magnets, the first frame being made of a first material; and a second frame that surrounds the plurality of rotor core segments, the plurality of permanent magnets, and the first frame and that couples the plurality of rotor core segments, the plurality of permanent magnets, and the first frame to one another. The second frame is made of a second material different from the first material.

  • Patent number: 11258321
    Abstract: A motor includes a stator and a rotor rotatably coupled to a rotation shaft. The rotor includes: rotor core segments arranged along a circumferential direction of the rotor on the inner side or the outer side of the stator and spaced apart from one another to define permanent magnet arrangement slots between the rotor core segments; permanent magnets inserted into the permanent magnet arrangement slots, respectively; and a rotor frame including rotor frame pins that fix each of the permanent magnets between the rotor core segments. Each of the rotor core segments defines a rotor core hole that extends parallel to an axial direction of the rotation shaft.
