  • Patent number: 10224774
    Abstract: A method for mounting laminated sheets onto a shaft of a rotor provided for an electrical machine may involve sliding the laminated sheets onto the shaft and bracing the laminated sheets between two rotation-resistant thrust washers connected with the shaft. The laminated sheets may be slid onto the shaft to lie against a stop in the form of a first thrust washer arranged upon a first subsection of the shaft. A second thrust washer may be pressed in by axially bracing the laminated sheets onto a second axial subsection of the shaft in a frictional interlocking manner. The second thrust washer may be positioned after a surface of the second subsection has been enlarged by the introduction of an exterior surface profile.

  • Patent number: 8574291
    Abstract: The invention relates to an electrical linear drive, in particular for a pump system of an artificial heart, with a movable part and a stationary part, wherein the stationary part is formed by a permanent magnet arrangement and the movable part is formed by a coil arrangement, or vice versa, and wherein the coil arrangement and the permanent magnet arrangement can be moved to and fro relative to each other in an axial direction by means of current passed through the coil arrangement. The invention further relates to an electrical linear drive of this kind in which the permanent magnet arrangement is designed as a stack of frame-shaped, in particular ring-shaped magnets, which are magnetized alternately radially and axially in the axial direction, such that the magnetic field is strengthened on one side of the frame.
