摘要:
The invention concerns a magnetic guiding device (1) having at least one element (2) to be guided magnetically in the axial direction, e.g. a shaft or an actuation member that is movable in the axial direction, the element (2) having a radial flange (14) made of magnetizable material that is enclosed by an axial yoke (47) made of ferromagnetic material and constituting a stator, forming magnet gaps (51, 52) in which is producible, by means of a combination of permanent magnets and electromagnets (53, 54, 55), an axial magnetic flux with which the axial position of the element (2) can be influenced, which is characterized in that in the axial yoke (47), at least one pair of axially oppositely polarized permanent magnets (53, 54) are arranged axially next to one another, and an electromagnetic coil (55) is moreover arranged radially adjacently as an electromagnet, the magnetic flux in the coil (55) being controllable in such a way that an asymmetrical magnetic flux having an axial resultant force is producible in the magnet gaps (51, 52).
