    摘要: The invention relates to a magnetic axial bearing for taking up axial forces that act on a rotor component that is rotatably supported about a rotational axis with respect to a stator component. The bearing comprises a first bearing part consisting of at least one permanent magnet and at least two flux guide elements associated with the permanent magnet that are disposed on opposing end faces of the permanent magnet and aligned substantially radial and perpendicular to the rotational axis, and a second bearing part consisting of at least two flux guide elements that are disposed at a mutual spacing to one another and aligned substantially radial and perpendicular to the rotational axis, each flux guide element of the second bearing part being associated with a flux guide element of the first bearing part and lying directly opposite the latter in a radial direction and separated from it by an air gap. The invention further describes a spindle motor having a magnetic axial bearing of this kind, used, for example, for driving a hard disk drive.

    摘要: An electromechanical energy converter (1) is provided that can convert mechanical vibration energy into electrical energy. For this purpose, the energy converter (1) has a housing (2) in which a coil (12) and a permanent magnet (15) are disposed moveable with respect to each other, the coil (12) lying within the magnetic field of the magnet (15). To fully utilize the entire field intensity of the magnet (15), flux guides (18) are disposed at the poles of the magnet (15) that divert the magnetic flux lines (17) substantially in the direction of the coil (12).
