  • Patent number: 9806576
    Abstract: An armature includes plural core configuration members and plural insulators integrated with the core configuration members, each insulator including a coupling portion that couples a pair of insulation portions. The armature includes plural coil wires, each including a pair of wound portions wound onto respective core configuration members, and a crossing wire connecting the pair of wound portions. Plural armature configuration units are configured independently by integrating a pair of the core configuration members with each insulator and winding the coil wire onto the pair of core configuration members. Plural armature configuration sections are configured by combining two armature configuration units adjacent in the circumferential direction.

  • Patent number: 8482180
    Abstract: An inner rotor type brushless motor includes a stator. The stator is made of a plurality of stator sections. Each one of the stator sections has a plurality of core members, an insulator, and a winding wound on the core members via the insulator. The core member includes a yoke portion and a tooth portion. The insulator includes a ring portion to connect the core members. Since each stator section can provide sufficient distance and space between two core members on the same stator section, it is easy to wind the winding on the tooth portions. The stator sections can be assembled along an axial direction to form the stator. The yoke portions are circumferentially arranged to connect each other to form a magnetic path.

  • Patent number: 8166629
    Abstract: A stator having a stator core and coils is disclosed. The stator core includes split core pieces each having a tooth portion. The split core pieces are arranged annularly such that the distal ends of the tooth portions face radially inward. A lead wire is continuously wound about an adjacent pair of the tooth portions such that coils of different phases are formed in the circumferentially adjacent tooth portions, so that a plurality of connecting wires are provided, each connecting wire connecting coils of different phases. The connecting wires are connected to one another while being connected to one another, such that a neutral point is created.

  • Patent number: 5043035
    Abstract: In a method of disassembling resin-molded equipment, a gap is formed in the boundary portion between a metal body and a resin layer disposed around the metal body in order to separate the metal body is separated from the resin layer. To form the gap, either the metal body or the resin layer may be heated, so that the gap is formed by the difference in thermal expansion between the metal body and the resin layer. Alternatively, a microorganism such as ray fungus of Nocardia is attached to the boundary portion between the metal body and the resin layer, and decomposes the resin to form the gap. Since the gap reduces the bonding strength between the metal body and the resin layer and in some cases the metal body may even separate from the resin layer, the metal body may be pulled out with ease.
