Abstract: A linear motor system comprises a plurality of stator elements that have one or more magnetic coils for generating a magnetic flux in the respective stator element and at least one mover that has at least one magnetic element that interacts with the magnetic coils of the stator elements. The mover is moved by means of activation of at least one stator element in a direction of movement relative to the stator elements. At least one selected stator element is configured to change with respect to the magnetic flux from a first state into a second state or to have the second state permanently while at least some of the other stator elements remain in the first state so that the selected stator element exerts a braking and/or holding force on the mover in the second state.

Abstract: A drive arrangement with an inductively energizable drive motor, having a wheel, a wheel carrier, at least one receiver coil that is arranged in the circumferential direction of the wheel, a stator, and a rotor arranged in a rotationally resistant manner on the wheel having at least one rotor winding that is electrically connected to the at least one receiver coil. The rotor can be magnetically coupled to the stator. In this case, the drive arrangement is configured such that a current can be induced by an underground base providing a magnetic field in the at least one receiver coil, by which the at least one rotor winding is energized to generate a magnetic field.

Abstract: A method for operating a rotation damper for a motor vehicle which has an electric generator with a stator and a rotor includes detecting with a direction of rotation detection module a change of a direction of rotation of the rotor relative to the stator between a first direction of rotation and a second direction of rotation which is opposite to the first direction of rotation; generating with the direction of rotation detection module a signal indicative of an actual direction of rotation of the rotor relative to the stator; and as a function of the signal conducting an electrical current converted by the electric generator to a first electrical load having a first resistance value when the rotor rotates in the first direction of rotation, or to a second load having a second resistance value when the rotor rotates in the second direction of rotation.
