  • Patent number: 9106116
    Abstract: A rotor of a rotating electrical machine includes a rotor core which includes an annular core plate formed by coupling a plurality of arc shaped core plate pieces. Multiple core plates are stacked together. A circumferential position of a seam formed by coupling the core plate pieces is alternately displaced for every predetermined number of core plates in a stacking direction of the core plates. A bar-shaped member is inserted in a plurality of through holes formed in the respective core plate pieces and aligned in the stacking direction. Both side surfaces of the rotor core in the stacking direction are interposed between end plates, the end plates contact the core plates, and the end plates do not contact the bar-shaped member at least on a radially outside of the bar-shaped member, which is a side in a direction of a centrifugal force that acts on the bar-shaped member.

  • Patent number: 8193631
    Abstract: A first interconnection is formed along a groove of a substrate and on a bottom surface of the groove, and has a first thickness. A second interconnection is electrically connected to the first interconnection and has a second thickness larger than the first thickness. An acceleration sensing unit is electrically connected to the second interconnection. A sealing unit has a portion opposed to the substrate with the first interconnection therebetween, and surrounds the second interconnection and the acceleration sensing unit on the substrate. A cap is arranged on the sealing unit to form a cavity on a region of the substrate surrounded by the sealing unit. Thereby, airtightness of the cavity can be ensured and also an electric resistance of the interconnection connected to the acceleration sensing unit can be reduced.
