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 ). |
