  • Publication number: 20200391784
    Abstract: A stopper device for vehicle includes a movable member, a swing lever capable of swinging in the direction in which the movable member is locked, a solenoid coupled to the swing lever, and a pushing member that pushes the swing lever in the unlocking direction relative to the movable member. The solenoid includes a plunger coupled to the swing lever, and a magnetizing coil to drive the plunger.

  • Patent number: 6998750
    Abstract: Several embodiments of permanent magnet type three-phase AC rotary electric machines wherein the phase current flow is formed by parallel circuits formed by a plurality of serial circuits each comprising one or a plurality of stator coils so that electromagnetic voltage or counter electromagnetic voltage generated across opposite ends of the plural serial circuits may be always almost the same. Thus, a circulating current does not flow in the parallel circuits, whereby the efficiency of the rotary electric machine can be improved. Also, since the line current circuit of each of the phases is constituted of a parallel circuit, the current flowing in each of the stator coils is small so that the diameter of the stator coil wire can be small. Thus, the winding of the coils can be improved. Also, the processing of the coil terminals is facilitated and the processed portions of the terminals can be made small, resulting in a compact rotary electric machine.

  • Publication number: 20020145348
    Abstract: Several embodiments of rotors for rotating electrical machines configured to increase the stiffness without increasing the weight and to promote the flow of coolant across the rotor. This is achieved by utilizing stiffening ribs and flow openings in an intermediate portion of the rotor that interconnects the cylindrical portion that carries the permanent magnets and the hub section.

  • Publication number: 20020047459
    Abstract: A rotating electrical machine such as an electrical generator that can be utilized to provide high efficiencies and high outputs in connection with a compact construction. This achieved by having a plurality of spaced permanent magnets of opposite polarity that cooperate with armature coils. The armature coils are wound around core teeth formed from an electromagnetic steel plate having a thickness in the range of 0.25-0.65 mm. The permanent magnets are disposed in circumferentially spaced orientation relative to the axis of relative rotation at a magnet electrical angle &thgr; that is in the range of 120° to 140°.
