摘要： A rolling bearing device includes a bearing portion and a power generation portion. The power generation portion has a plurality of projecting portions provided on an outer ring spacer, a pair of core members provided on an inner ring spacer, a magnet, and a coil. The power generation portion generates an induced current in the coil as the projecting portions pass in the vicinity of first side end portions of the core members during rotation. There are two different loop paths along which magnetism generated by the magnet flows: a first loop path formed when the projecting portions are close to the first side end portions of the core members; and a second loop path formed when the projecting portions and the first side end portions of the core members are away from each other.

摘要： A magnetic bearing system for support of a body, such as an energy storage flywheel, for rotational about a substantially vertical axis of rotation through its center of mass. The bearing system includes a rotating portion and a stationary portion on each axial side of the center of mass. Two or more concentric axially magnetized ring poles on an axial surface of the rotating body are constructed of multiple individual permanent magnet pieces, arranged in rigs inside a containment cup in the end face of the rotor with radially adjacent rings having alternating magnetic polarities. On the stationary portion, two or more concentric axially magnetized pole rings of permanent magnet material cooperate with the rotating ring magnets to produce both an axial attractive force and a radial centering force.

摘要： A novel rotary mechanism comprising a stator body defining a chamber and an elongated rotor operationally disposed within the chamber. The elongated rotor has opposed ends with a central axis defining an axis of rotation, with magnetic driven means disposed on the rotor and positioned outwardly of the rotor axis between the opposed ends. Passive magnetic bearing pairs are positioned along opposed ends of the rotor body with each bearing pair being similarly polarized so as to be in mutually attracting or mutually repelling relationship. A third passive magnetic bearing pair is positioned along the rotor axis between the opposed ends with the third bearing pair being magnetically coupled similarly to the first and second bearing pairs, with the passive magnetic bearings creating an unstable negative force in a plane perpendicular to the axis of rotation of the rotor with the negative stiffness being overcome upon rotation of the rotor creating a centrifugal force of a magnitude greater than that of the unstable negative force.

摘要： Radial, soft magnetic rotor disk elements which engage in each other and soft magnetic stator disk elements form a magnetic bearing device. The elements are provided with teeth-like extensions which are arranged opposite to each other over an air gap on sides which are oriented towards each other. Magnetic fields, which may be produced by permanent magnets or electromagnets, are assigned to the stator disk elements to produce a magnetic maintaining flow which is oriented in an axial direction between the disk elements for radial adjustment. An electromagnetic winding is also provided in the region of the central plane of the bearing device for axial adjustment, which enables a magnetic control flow, which superimposes the magnetic maintaining flow, to be produced.
