Abstract: A magnetic linear drive has a coil in whose interior the current can produce a magnetic flux in an axial directions, having an armature which can move only at right angles to the axial direction and which has a magnetically active part which is magnetized, in particular, parallel to, but in the opposite direction to, the axial direction. The armature is driven by a current surge which accelerates the magnetically active part toward the coil center irrespective of its initial position.

Abstract: The invention relates to a magnetic bearing assembly of a rotor in a stator, with at least one magnetic bearing (1) comprising a stator part (2) and a rotor part (3) arranged coaxially thereto in the operating position without contacting the stator part. The bearing effective area of the rotor part is formed by a radial exciting system (6) having a permanent magnet (4), while the stator part (2) comprises a high-temperature superconductor concentrically surrounding the radial exciting system (6) while maintaining an annular air gap (10).

Abstract: An electromagnetic accelerator arrangement includes a stationary arrangement including at least one stationary primary coil, and a movable arrangement including at least one moveable secondary coil. The planes of the stationary and the moveable coils are parallel to a direction of movement of the moveable arrangement. The coils of the stationary and the movable arrangements have approximately the same coil width in the direction of movement of the moveable arrangement and transversely thereto, as well as the same coil separation in the direction of movement of the moveable arrangement. The at least one stationary primary coil includes at least two layers between which the at least one secondary coil of the movable component is movably disposed, the distance between the layers being kept small transversely to the direction of movement of the moveable arrangement.

Abstract: An electrical machine, which may be designed as a rotating machine or as a linear drive, includes a stationary part having an odd number multiphase winding (preferably five or seven phases), and a movable part separated from the stationary part by an effective gap. Each pole of the movable part includes two pole portions which diverge from each other in the direction away from the effective gap and between the end regions of which at the effective gap a magnetically non-conductive separating gap is provided which is greater than the effective gap. In such a machine, which is characterized by a permanent excitation in the movable part, there is provided between the proximate pole portions of each of adjacent poles a respective permanent magnet, the direction of flux of each permanent magnet being directed oppositely to the direction of flux of each adjacent permanent magnet.
