  • Patent number: 7348704
    Abstract: A rotor of a motor includes a cylindrical magnet having at least one first coupling portion at an inner circumferential surface of the cylindrical magnet; and a rotor core coupled with the cylindrical magnet, the rotor core having at least one second coupling portion at an outer circumferential surface of the rotor core, the at least one second coupling portion being engaged with the corresponding at least one first coupling portion.
    Type: Grant
    Filed: January 25, 2006
    Date of Patent: March 25, 2008
    Assignee: LG Electronics Inc.
    Inventors: Young-Kwan Kim, Deok-Jin Kim, Byung-Taek Kim, Jin-Soo Park
  • Patent number: 7161271
    Abstract: A motor for a washing machine includes a stator core having one or more bolt thru holes. A stator assembly having the stator core is directly coupled to a bearing housing using the bolt thru holes.

  • Publication number: 20060055263
    Abstract: Disclosed is a rotor of a BLDC motor including a frame rotatably disposed on an inner circumference of a stator, rotor teeth connected to the outer circumference of the frame in the radial direction at regular intervals, and magnets fixed between the rotor teeth, and arranged in the radial direction so that the facing sides can have the same polarity. The rotor of the BLDC motor improves a torque of the motor by minimizing flux leakage of the magnets.

  • Patent number: 6954018
    Abstract: Disclosed are a rotor of a line start permanent magnet motor and a manufacturing method thereof. The rotor comprises: a core provided with an axial hole for inserting an shaft and a plurality of penetrated magnet coupling holes formed at a periphery of the axial hole; permanent magnets respectively coupled to the magnet coupling holes of the core; a third end ring provided with magnet paths for respectively passing the permanent magnets and coupled to one side surface of the core; a fourth end ring having the same appearance as the third end ring and coupled to another side surface of the core to be connected with the third end ring; a magnet supporting plate positioned between one side surface of the core and the fourth end ring for preventing the permanent magnets from being separated; and a fixing member inserted into the magnet paths of the third end ring for preventing the permanent magnets from being separated.
