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 for the mounting of a shaft, in particular for a spinning rotor of an open-end spinning device, features several pole shanks of a stator for the active radial magnetic mounting of the shaft in two degrees of freedom, which in each case are surrounded by a coil and are radially arranged to each other, in such a manner that they define an opening for the shaft. In the area of the opening, the pole shanks are connected to each other. For the passive axial mounting of the shaft, at least one permanent magnet is arranged between the coils and the opening. The invention also includes a shaft for mounting with at least one corresponding magnetic bearing. The shaft is a composite component, which at least partially consists of non-ferromagnetic material. In the area of the radial and axial mounting, a component made of a ferromagnetic material is arranged. A shaft mounting is also provided and features, for the passive axial mounting of one degree of freedom of the shaft and for the active radial mounting of two degrees of freedom of the shaft, at least one, preferably two, corresponding magnetic bearings.

摘要： A magnetic bearing device (1) with an improved vacuum-tight electrical feedthrough through its housing (10) is disclosed. The feedthrough (30) comprises a flat connection element (31) such as a rigid or flexible printed circuit board extending through the wall of the housing (10), preferably all the way along an inner circumference of the housing. The connection element is sealed in a gas-tight manner to the housing. The element preferably has a central opening (36) for receiving the rotor shaft. Connections to the bearing units and sensors may be achieved by flat-ribbon cables (51) or flexprints. The sensors are preferably also implemented as printed sensors. Thus a very compact and cost-efficient magnetic bearing device can be obtained. An alternative embodiment uses a connection element on a side wall of the housing as a feedthrough to the bearing components.
