<p>By an appropriate arrangement of a permanent magnet (4) and ferromagnetic conducting material a stable levitation and carrying condition can be obtained. The permanent magnet (4) places the ferromagnetic material into a state of partial magnetic saturation. In order to move the load held by the magnet (4) as easily and efficiently as possible, electro-magnets are to be arranged in such a way that they influence the movement of the permanent magnet (4) in that, taking into account the magnetic saturation of the carrier section (1), the magnetic circuit generated by coupling the permanent electro-magnetic force fields tries to shorten itself. As a further development of the invention the coil cores (2) too can be integrated into the permanent-magnetic partial saturation which leads to the levitation and carrying condition so that a change in the saturation and thus the envisaged movement can be achieved by relatively few components, with little wear and a relatively small amount of electrical energy with which the coils (3) need to be supplied.</p> |
