The
system for generating electrical energy enables the generation of electrical energy in a
linear motion device having a first device component and a second device component, wherein the second device component is supported on the first device component via rolling elements (WK), such that the second device component is linearly movable relative to the first device component. The
system for generating electrical energy comprises: the rolling elements (WK), which are movable along a direction of movement (BR) during operation of the
linear motion device;a device (PM) for generating a static
magnetic field in a spatial region (RB) which the rolling elements (WK) must
traverse one after the other during operation of the
linear motion device during a movement along the direction of movement (BR), wherein the rolling elements (WK) consist of a magnetically permeable material, so that the rolling elements (WK) are suitable for influencing the
magnetic field depending on the position of the rolling elements (WK) in the one spatial region (RB);and at least one
induction coil (IS) with at least one coil turn, wherein the at least one
induction coil (IS) is arranged stationary relative to the device (PM) for generating a static
magnetic field in such a way that, due to a change in the position of the rolling elements (WK) during a movement of the rolling elements (WK) along the direction of movement (BR) through the one spatial region (RB), it experiences a change in a
magnetic flux which induces an electrical
voltage (Uind) in the at least one coil turn;
